Data acquisition modifications for improved reconstruction with conventional CT

Methods and corresponding apparatus for imaging a portion of a patient's body with a computed tomographic imaging system configured to scan the patient's body at a cyclically varying view angle, in which the imaging system includes a radiation source and detector array providing a fan angle width of image data. In one embodiment, the method includes axially scanning the portion of the patient's body, gating the radiation source on over less than a 360 &deg;view angle cycle of the axial scan, acquiring image data of the portion of the patient's body during at least a portion of the time the radiation source is gated on, and assembling the acquired image data into an image of the portion of the patient's body.

Methods and apparatus for reduced radiation coronary computed tomography imaging

A CT imaging system employs a command sequencer to control the operation of the x-ray source and the data acquisition system. The command sequencer stores a set of commands in a FIFO memory that are read out in sequence to perform a scan. Each command contains a count field which indicates how long it is active and other fields enable different clock sources to be selected, enable commands to be repeated and enable command execution to be halted.
