HI! I'm an Italian Radiologic Technologist and I'm going to make a lesson in the future development of CT Technology. Can someone have some useful links to give me? For example I'd like to know if the new 128slices from Siemens uses the ceramic detector or the flat panel...

i think the siemens uses the ceramic on the 128 slice. the flat panel is a different scanner along with the dual source. i've got a basic history of ct if that will help.

1967 Hounsfield concieves idea for CT
1968 invention of CT EMI Scanner (named for the record company funding the rescearch - funds from record sales of the beatles) Hounsfield
1970 1st generation scanner (pencil beam)
1972 2nd generation (partial fan beam) and first production of CT image Hounsfield
1973 - first whole body scanner, and first scanner that did not need water bath 0100 ACTA Scanner (automated computerized transverse axial) Ledley (DDS)
1976 3rd generation scanner (rotating tube and detector)
1978 4th generation (rotating tube, stationary detector array)
1985 Slip ring technology, and a one second scan
1989 (around) EBCT imaging for the heart (some consider 5th generation)
1989 Spiral CT 6th generation (3rd and 4th generation scanners)
1991 Twin Detector Elsent
1995 Sub Second scanning
1998 MDCT
1999 Half second scan
2001 PET/CT fusion
2002 16+ slice CT
2005 Siemens introduced dual X-ray tube and dual array of 64 slice detectors, at the 2005 RSNA
2007 RSNA, Toshiba announces Aquilion ONE, first scanner to image heart in one rotation (320 slice), minimum detector width of 0.5mm, 16cm coverage

any input from you other guys would also help me out with this.

otherwise, jacopo, i'd contact the separate scanner companies to find out that information.

Thanks for your kind answer...to say the truth I've tried to get in touch with some scanner companies but with no great results...I'd be satisfied if I could get some lectures of the last RSNA meeting in Chicago...does anyone know how to get them?

jacopo, Sorry I couldn't find a good breakdown either. suggest you take a look at the UK site www.impactscan.org.
