General Information

Loading Studies

There are three ways to load a study into an application. See the section on “Loading a Study” in the JETStream Workspace Instructions for Use for details. To run an application directly, click its button on the application toolbar.

Object Associations

Each application is configured to open studies with specific object names (a field in the study’s header). To change the object names an application accepts, see “Matching Datasets to Dataset Drop Boxes” in the Configuring JETStream Workspace Instructions for Use. If you try to use an application to open a study with incompatible object names, a message appears stating that auto-matching failed, and asking if you want to open it manually.

Common Controls

The controls in the top toolbar are common to all applications: exiting, saving, printing, annotating, etc.:


Figure 1 Common controls

For information on these, see the section on “Common Tasks” in the JETStream Workspace Instructions for Use.

JET

General Information

Viewing Snapshots and Pages

Most of the JETStream Workspace applications include layouts for viewing the following types of screenshot images:

• Snapshots

Snapshots are screenshots saved from systems other than JETStream Workspace (e.g., secondary captures; or snapshots from a Pegasys, whose snapshot filenames contain the suffix _SS).

• Pages

Pages are screenshots saved from a JETStream Workspace application.

You can load multiple snapshots and pages into an application, although you can view only one snapshot or page at a time.

If you have loaded more than one snapshot or page, a screenshot button appears on the layout toolbar in the appropriate layout for each snapshot or page you have loaded. The tooltip for each button is the filename of the corresponding image; click a button to view that image.

Figure 2 Screenshot button

You can also use the Previous Object and Next Object


buttons to browse through multiple snapshot and page images.

General Information

8

Figure 3 Previous Object and Next Object buttons

Note Many of the JETStream Workspace applications allow you to load and view only a snapshot or a page (without other datasets). For some applications, however, you must load the application’s minimum dataset requirement with any snapshots or pages you want to view. For each of these applications, this restriction is indicated in its corresponding chapter.

Snapshot Layout

The Snapshot layout displays a single snapshot image in a 1-zone display.

For snapshots, the only image control you have is colormap choice. For more on this, see “Controlling Image Colors” in the JETStream Workspace Instructions for Use.

Note Although multiple images may appear in a snapshot, they cannot be selected individually, since they are displayed only as part of the snapshot.

Page Layout

The Page layout displays a single page image in a 1-zone display.

Previous Object

Next Object


Unlike the Snapshot layout, the Page layout is interactive: With the exception of layout toolbar buttons, the same basic JETStream Workspace controls that were available in the layout from which a page was saved are available in the Page layout display of that page.

JET

Warnings and Precautions

Warnings and Precautions

C a u t i o n It is important to note that when you use Load during a manual load, JETStream Workspace may not load the objects in the proper thumbnail squares. This means that some objects may be mislabeled in the application.

C a u t i o n Do not use captured images or saved screens for diagnostic use. They may not include all the information necessary for a diagnosis. For this reason, they are only for reference, or inclusion in documents such as reports and presentations.

C a u t i o n Ensure that any hardcopy output that is to be used for interpretation is of diagnostic quality (printed on Codonics printers, for example). Non-diagnostic output may lead to misinterpretation.

Quality Assurance

This application module requires no diagnostics, calibration, or testing.

Layout Tools and Graphic Controls
What this Chapter Contains

This chapter contains the following sections:

• Introduction (page 11)

• Tools and Controls (page 12)

Introduction

The applications described in this book contain various layout tools and graphic controls that appear either as buttons in the layout toolbar or in various forms (e.g., sliders) next to viewports in which you use them. These tools can be divided into two basic categories:

• Image Display

Buttons and sliders you use to change the appearance of displayed images.

• Layout Display

Stream Workspace Display Applications 2: Layout Tools and Graphic Controls 11

Buttons you use to change what images and data are displayed in a layout.

This chapter contains descriptions of tools and controls that appear in applications in the JETStream Workspace Review Module.

Tools and Controls

12

Note The tools and controls do not appear in all applications or layouts; depending on the loaded datasets, all layouts may not be available in an application.

Tools and Controls

Image Display

Isolevel

The Isolevel sliders appear in the following applications:

• Fusion Display




2: Layout Tools and Graphic Controls JETStream Workspace Display Applications

Figure 4 Isolevel sliders

JET

Tools and Controls

The Isolevel sliders adjust the threshold of the counts displayed in a 3D isocontour image. The thresholds, on a scale from 0 to 1, appear below each slider.

For images that display a single 3D isocontour image, only the Isolevel 1 slider is available.

For viewports that display two overlaid isocontour images generated from the same dataset (a “hot” area in the context of a larger volume), the Isolevel 1 slider affects the image that displays the upper isolevel range only; the Isolevel 2 slider affects the image that displays the entire isolevel range.

For viewports that display fusion images generated from two different datasets (e.g., functional and anatomical), the Isolevel 1 slider affects the functional image; the Isolevel 2 slider affects the anatomical image.

Slice Thickness

The Slice Thickness buttons appear in the following applications:





There are two Slice Thickness buttons.


Figure 5 Slice Thickness buttons

Increase slice thickness

Decrease slice thickness

Tools and Controls

14

The Slice Thickness buttons allow you to change the thickness of the slices displayed by summing adjacent slices of a multiframe dataset. Use the Increase Slice Thickness button to increase the number of frames summed; use the Decrease Slice Thickness button to decrease the number.

Summing begins with the first frame in the dataset. Clicking the Increase Slice Thickness button once sums frames 1 and 2, 3 and 4, and so on; clicking it twice sums frames 1 through 3, 4 through 6, and so on. The Decrease Slice Thickness button functions similarly (on frames already summed).

Each summed frame represents the average activity for each pixel across the range of summed slices. For SPECT volumes, you can sum up to 5 images. For dynamic studies, you can sum as many frames as there are in the dataset.

Refer to the JETStream Workspace Instructions for Use for more information on summing images.

Transparency

The Transparency sliders appear in the following applications:


• Fusion Display


JET

Tools and Controls

Figure 6 Transparency sliders

The Transparency sliders adjust the overlay ratio of 3D isocontour images when two such images are displayed in a single viewport (overlaid or fusion images).

For viewports that display two overlaid isocontour images generated from the same dataset (a “hot” area in the context of a larger volume), the Transparency 1 slider changes the contribution from the image that displays the upper isolevel range only to the composite 3D image; the Transparency 2 slider changes the contribution from the image that displays the entire isolevel range to the composite 3D image.

For viewports that display fusion images generated from


two different datasets (e.g., functional and anatomical), the Transparency 1 slider changes the contribution from the functional dataset to the composite 3D image; the Transparency 2 slider changes the contribution from the anatomical dataset to the composite 3D image.

Tools and Controls

16

The thresholds, on a scale from 0 to 1, appear below each slider. Setting either slider level to 0 displays just the information from the other image or modality. Higher numbers increase the visibility of data.

Zoom

The Zoom slider appears in the following applications:



• Fusion Display


Figure 7 Zoom slider

Using the Zoom slider, you can adjust the display size of an


MIP image. Drag the slider up to enlarge the image and down to shrink the image. The zoom factor, on a scale from 1 (smallest) to 10 (largest), appears below the slider.

JET

Tools and Controls

Layout Display

Normalization

The Normalization buttons appear in the following applications:


• Renal Display

• Gastric Emptying Display


• Lung Washout Display

There are three Normalization buttons.

Figure 8 Normalization buttons

Depending on the layout and the datasets you have loaded:

• All Normalization buttons may not be available.

• Multiple sets of Normalization buttons may be available. Each tooltip indicates which images the button affects (series, frame, or myocardium).

Normalize to series

Normalize to each frame

Normalize to myocardium


Clicking the Normalize to the series button performs the usual normalization using the hottest pixel in the entire slice volume (for volume datasets) or series (for dynamic datasets). This button appears in both cardiac and non-cardiac applications.

Tools and Controls

18

Clicking the Normalize to each Frame button normalizes to the maximum pixel value in the superior half of the pixel data space in each frame. This button appears only in non-cardiac applications.

Clicking the Normalize to myocardium button normalizes each cardiac slice individually to the maximum pixel value in the myocardium. This button appears only in cardiac applications.

For more on normalization, see “Adjusting an Image’s Dynamic Range” in the JETStream Workspace Instructions for Use.

Basic JETStream Workspace controls, such as keyboard commands and right-mouse controls, are available in this layout. Descriptions of all basic controls can be found in the JETStream Workspace Instructions for Use under “Basic Image Controls.”

2D Image Controls

Here are some of the controls that may appear when you right-click in a viewport in this layout:

• Browse

• Pan

• Zoom

• Background:Brightness

The Background:Brightness Functional control affects the functional image; the Background:Brightness Anatomical control affects the anatomical image.

• Overlay Ratio

The Overlay Ratio control adjusts the contribution for each dataset to the composite image. Drag on an image right or left to change the anatomical image, and up or down to change the functional image.

MIP Controls


You can use the Palette panel (<F4>) to change the image’s color display using the Secondary colormap controls.

• Use the Zoom slider to enlarge and shrink the image.

You can change the display by right-clicking in it and selecting from the menus:


24

• To toggle between the MIP (Maximum Intensity Projection) display and a 3D display, select 3D or MIP.

• Select Cine to animate the view.

• Select a perspective from the list to change the view angle.

Additional menu choices are also available to control the image’s gamma value. Gamma adjusts the linearity of the colormap scale, which changes the image’s intensity and contrast. Log3 uses the highest gamma value (4.0), and Exp3 uses the lowest (0.3); Linear uses a gamma of 1.0.

3D Image Controls

In the volume viewport, drag with the left mouse button to rotate the image.

With the cursor positioned on the 3D isocontour image, you can use the up and down arrow keys on the keyboard to increase and decrease the zoom level.

Use the Isolevel sliders next to the 3D isocontour image to view areas in the image with identical counts. Since this is a 3D image, areas with identical counts define a volume.

Use the Transparency sliders to adjust the overlay ratio of the 3D isocontour image.


• To toggle between the MIP (Maximum Intensity


Projection) display and a 3D display, select 3D or MIP.

• 1 MIP image (and a 3D isocontour version)

The 3D isocontour image displays a “hot” area (an area of maximum counts) in the context of a larger volume by superimposing two images created from the same dataset.

The two images are rendered independently using the standard depth-dependent, surface reflection algorithm. The rendered images are then overlaid using the same (monochrome) scale for the upper and lower level iso-images. The lower level is shown in one intensity range, and the lower plus upper levels in a higher intensity range.


The upper level alone does not exist, since the upper isolevel is entirely contained within the lower isolevel.

JET


N ote For brain studies, the maximum activity level is normally in the cerebellum or occipital lobe. The SPECT volume should be attenuation-corrected for this to be relevant.

N ote Colormap changes do not affect the 3D isocontour image.

Optionally, in addition to the 4 required views, you can load the following:

• 2 additional perfusion or ventilation datasets in the following views: LPO, RPO

or

• 4 additional perfusion or ventilation datasets in the following views: LPO, RPO, LAO, RAO

You can load both perfusion and ventilation datasets in the same session, but the set of datasets for each type must be complete (4, 6, or 8 views), and each set must contain the correct views for the number loaded. You do not need to load the same number of views for both types of images (perfusion and ventilation).


This layout is available only if you have loaded at least 4 perfusion datasets in the required views.

This layout displays 4 to 8 views, depending on the datasets loaded:

• Anterior and Posterior

Introduction

The dynamic display applications provide a way to review hepatobiliary, renal, gastric emptying, and gastrointestinal bleed images acquired as dynamic studies. There are four dynamic display applications:


• Renal Display

• Gastric Display


Stream Workspace Display Applications 10: Dynamic Display 75

Introduction

76

Figure 38 Dynamic display application icons

The minimum dataset requirements for loading a study in these applications are shown in the table below.

Hepatobiliary Display

Renal Display

Gastric Display

GI Bleed Display

Application Minimum Dataset Requirements

Hepatobiliary Display 1 dynamic flow dataset + 1 dynamic function dataset

Note: Optionally, you can load a series of static datasets

in addition to the dynamic datasets.

Renal Display 1 dynamic flow dataset + 1 dynamic function dataset

or

1 dynamic multi-phase dataset

Gastric Display 1 dynamic anterior dataset + 1 dynamic posterior dataset

Note: Optionally, you can load a series of static datasets

in addition to the dynamic datasets.

GI Bleed Display 1 dynamic flow dataset + 1 dynamic function dataset

Optionally, you can load a dynamic multi-phase dataset

and/or a series of static datasets, in addition to the

dynamic flow and function datasets

10: Dynamic Display JETStream Workspace Display Applications

Note If a GI Bleed study is loaded during the workflow, you may see a document error and an automatching setup error. This can happen when you have only a dynamic function image (the application expects both flow and function

JET

Series Layout

objects). If this happens, you can use the GI Bleed icon and load the study into both the Flow and Function buckets. You can also use the Layout Editor to allow such a situation:

1 In JETStream Workspace, select Edit->Layouts.

2 Select the GI bleed display and choose a patient.

3 In the Layout Editor, right-click on the flow icon.

4 Set excludes to “Anterior Dynamic” or whatever you call that function at your site.

5 Save the layout and exit the Layout Editor.

You will still receive the error “Scripted operation failed copy:function Copy function code 1,” because the program expects a flow, but if you click OK, the data will still display. If a dataset is loaded into the Function bucket instead of Flow, the error message reports “flow” in place of “function” in the above error.

Series Layout

For each dataset you have loaded, this layout displays the following:

• 1 cine

• 8 image frame display



• 64 x 64

• 128 x 128

• 256 x 256
