  1. Computed Tomography

  2. Proviz 8 Multi-slice CT Scanner 2003 CT-C3000Dual Dual-slice CT Scanner CT-C3000 2002 1999 2000 Spiral CT Scanner CT-C2000 Whole body CT scanner 1998

  3. CT-C3000

  4. CT Working Principle Image display X-ray generation Data acquisition Reconstruction and post-processing

  5. Conventional Scanning Scanning Interval Scanning Interval ◎ Scanning speed is restricted because of non-continuous scanning.

  6. Spiral Scanning Spiral Scanning = Volume Scanning

  7. Working Principle of Spiral CT Scanner ◎ Continuous rotation of X-ray tube and detectors ◎ Continuous emission of X-ray ◎ Continuous couch move-in at an even speed ◎ Continuous data acquisition

  8. Advantage of Spiral Scanning More easy to patient exam Increase outpatient Scanning speed is increased greatly Reduce motion artifacts Lower dosage of enhancement medium Reduce mechanical faults + Reduce the missed diagnosis Image post-processing making 3D visualization into reality Volume scanning

  9. ◎ More easy to patient exam Advantage of Spiral Scanning Breath motion Successful holding breath Reduce breath and motion artifacts

  10. ◎ Increase outpatient Advantage of Spiral Scanning

  11. ◎ Lower usage of enhancement medium Advantage of Spiral Scanning Artery phase Portal vein phase To acquire different phases images of viscera

  12. ◎ Thin slice scanning of large range Advantage of Spiral Scanning 10mm scanning 3mm scanning Nodular pathologic changes can be displayed clearly.

  13. MPR Advantage of Spiral Scanning 3D

  14. Advantage of CT-C3000 ◎ High speed ◎ Thin slice ◎ Strong capability of spiral scanning ◎ High quality images ◎ Rich functions of image processing

  15. 360°/sec. High Speed Clinical application： ◎ Volume scanning of ROI can be achieved with holding breath one time ◎ Reduce the missed diagnosis rate of small focus without interval data acquisition ◎ Reduce breath and motion artifacts ◎ Easy to acquire enhancement image Advantage of CT-C3000

  16. Thickness of 1mm Thin slice Clinical Application： Advantage of CT-C3000 ◎ Increase diagnosis rate of small focus ◎ reconstruction with high resolution ◎ The base of 2D and 3D reconstruction

  17. Strong capability of spiral scanning Continuous scanning of 80sec. Basis Advantage of CT-C3000 Top-grade configuration of CT-C3000 Key parts are imported from world leading manufactures.

  18. X-ray Tube Made by VARIAN Co. of U.S.A. Metal tube Dual focus Advantage of CT-C3000 ◎ Special designed for spiral CT of 1 and sub-second CT scanner ◎ Large heat storage capacity：3.5MHU ◎ High heat dispassion：750KHU／min.

  19. Advantage of Metal Tube Advantage of CT-C3000

  20. Advantage of metal tube ◎ Large heat storage capacity, high heat dispassion and strong capability of spiral scanning ◎ Increase images quality and extend service life of tube with restraining electron radiation. Advantage of CT-C3000

  21. Advantage of metal tube Advantage of CT-C3000 Large range continuous scanning can be achieved with 175mA and 80s.

  22. Dual focus technique Advantage of CT-C3000

  23. Contrast the large focus with the small one Large focus Advantage of CT-C3000 Small focus

  24. Heel effect of focus ◎ Focus of electron beam on the anode target is the same with heel on the floor. ◎ Sand blast will appear on anode target because of small focus. ◎ Image quality will be effected. Advantage of CT-C3000

  25. High voltage generator Made by Spellman Co. Apply high voltage and phase controlling technology ◎ Power：28KW ◎ Small volume and light weight ◎ Patent controlling technique ◎ Reduce noise effectively ◎ Reduce fluctuation of tube current and voltage ◎ Tube current and voltage can be controlled effectively and accurately. Advantage of CT-C3000

  26. Guarantee of high quality image Advantage of CT-C3000 More…… Super high speed GOS detector Slip ring and brush assembly made of silver plated copper Strong computer system Advanced system design

  27. Guarantee of high quality image Detector ◎ Made by Hamamatsu Co. of Japan ◎ Super high speed GOS solid detector ◎ Channel number：688 Advantage of CT-C3000

  28. Super high speed GOS detector ◎ Stand for the most leading level of the world ◎ X-ray absorptivity:99.98% ◎ Response speed: 40% higher than that of other materials ◎ Extra-short afterglow effect Advantage of CT-C3000 ◎ Images acquired from high-speed and long-time spiral scanning are much better than that of other materials.

  29. Guarantee of high quality image Slip ring and brush assembly Made by Litton Co. Silver plated copper Advantage of CT-C3000 ◎ Signals are transmitted accurately in real time. ◎ High stability and wearability ◎ 2000000 times is guaranteed by Litton Co.. ◎ Low cost maintenance

  30. Guarantee of high quality image Strong computer system Open workstation with Pentium IV multi-CPU ◎ Multi-task can be processing in parallel mode. ◎ Image reconstruction with high speed ◎ Huge capacity of image storage ◎ Easy to upgrade and low cost of maintenance Advantage of CT-C3000 1sec. 120000 images

  31. Computer system ◎ Main frequency：2.0G ◎ Memory：512MB ◎ Hard disk：80GB ◎ Multi-medium of storage：1.3GB MO disk,external hard disk,CD-R ◎ Monitor：21″ real-flat high resolution color monitor Advantage of CT-C3000
