MULTI-SLICE

• 4 slice since 1999

(GE, Siemens, Philips, Toshiba)• 8 slice since 2001

(GE)• 16 slice since 2002

(GE, Siemens, Philips, Toshiba)


MAIN PARTS Generator• High voltage generator 60 kw out put

X-ray tube• Rotating anode tube• Very high heat capacity

Detector• Solid state detector


DIFFERENCE


LIMITATIONS OF SINGLE SLICE CT

• Speed performance• MPR low accuracy• image quality and artifacts• More intravenous contrast


ADVANTAGES

• Improved spatial resolution.• Motion artifacts reduced.• Patient breath hold is much less demanding.• Imaging larger z-axis volume in less time.• Less contrast medium required.• Improved accuracy in needle placement CT

fluoroscopy.


ARTIFACTS IN MULTI-SLICE SCANNING

• Motion artifact reduced by faster scanning.• Stair-step artifacts in 3D reconstruction

reduced by using thinner slices.• Partial volume artifacts reduced by using

thinner slices.

DETECTOR DESIGN





MAJOR IMPACT AREAS FOR MULTI-SLICE CT

• The multi-slice technique has added new possibilities for faster, better and safer evaluation of many different disease



STELLAR DETECTOR• The stellar detector

provide ultra-thin slices.• very high spatial

resolution• It significantly reduces

electronic noise for uncompromised diagnostic outcome at a low dose.
