Abstract: A CT detector module utilizes a simplified FET that effectively sums detector cells in the X direction, allowing for a doubling of scan slices in the Z direction with the same or a lesser number of DAS channels found in conventional CT detector modules.

Abstract: An anti-collision method and apparatus for use with a C-arm x-ray imaging machine to prevent damage to the imaging apparatus and injury to patients and health care workers includes a load cell, a differential buffer and integrator, an analog to digital converter, and a microcontroller controlling the motor drive. The present invention also provides a method for controlling the apparatus via a microcontroller and includes the steps of determining whether an up/down switch is actuated, reading and comparing a value with a tabulated value, halting the C-arm if the difference between the tabulated value and the recorded value exceeds a threshold value and reversing the apparatus.
