I am having a big headache troubleshooting this GE ProSpeed CT system, hilight detector. There are multiple rings or band, not sure how to explain, different shape of gray, and a spot in the middle of the image with a circle of another gray around it.
The CAM LINEARITY TEST, NO X-RAY, is all out of specification, but not only one or two pulses, neither a periodic pulses, but a curve with lot of pulses, some up of specs, some under the specs. Just replaced the X-ray tube, Bow tie filter and CIF board.

Dear Friends:
I am having a big headache troubleshooting this GE ProSpeed CT system, hilight detector. There are multiple rings or band, not sure how to explain, different shape of gray, and a spot in the middle of the image with a circle of another gray around it.
The CAM LINEARITY TEST, NO X-RAY, is all out of specification, but not only one or two pulses, neither a periodic pulses, but a curve with lot of pulses, some up of specs, some under the specs. Just replaced the X-ray tube, Bow tie filter and CIF board.
PLEASE HELP!!

Try reinstall a copy of cal tables, and check the power of DAS. Check matrix scan for stripes or lines witj no correction tables.
