摘要： A tomographic x-ray imaging system comprises a large plurality of parallel data acquisition channels which integrate and digitize signals from an array of x-ray detectors. Calibration pulses are injected into each data acquisition channel to permit measurement of drift in electronic gain and dc offset parameters. Separate x-ray detectors continuously monitor the intensity of the x-ray source.The measured values for channel gains, dc offsets, and source intensity are fed to a digital computer where they are automatically combined with x-ray transmission data to compensate for system drift and extend the period between calibration measurements.

摘要： A multiple source, rotating, tomographic x-ray scanner includes x-ray sources adaptably configurable to operate in two modes. The first mode of operation, in which the sources are planarly configured, permits high speed, single slice scans to be made. The second mode of operation in which the x-ray sources are configured so as to scan distinct, but contiguous planes, permits multiple slices to be made in a single scan.
