multi slice

1. MULTI-SLICE CT Prepared by, Anand and Shonima

2. MULTI-SLICE AQUISITION 4 slice since 1999 (GE, Siemens, Philips, Toshiba) 8 slice since 2001 (GE) 16 slice since 2002 (GE, Siemens, Philips, Toshiba)

3. MAIN PARTS Generator High voltage generator 60 kw out put X-ray tube Rotating anode tube Very high heat capacity Detector Solid state detector

4. DIFFERENCE

5. LIMITATIONS OF SINGLE SLICE CT Speed performance MPR low accuracy image quality and artifacts More intravenous contrast

6. 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.

7. 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.

11. TECHNICAL SPECIFICATION

12. DETECTOR DESIGN

13. 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

14. 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.
