  • Patent number: 7015460
    Abstract: A method and apparatus for detecting radiation including x-ray, gamma ray, and particle radiation for nuclear medicine are described. A detection system employs fixed or configurable arrays of one or more detector modules comprising detector arrays that may be electronically manipulated through a computer system. The detection system, by providing the ability for electronic manipulation, permits adaptive imaging. The components of the imaging chain can be calibrated or corrected using processes of the invention. One or more reference sources with know properties (such as shape, composition, radionuclide activity distribution and energies, incorporated magnetic, acoustic inductive, or x-ray attenuating materials) can be inserted into the subject. The position of the reference sources can be monitored. Once the reference sources are near the desired location or locations they can be used to calibrate or tune the detection system. The detection system can be focused.

  • Publication number: 20040251419
    Abstract: A method and apparatus for detecting radiation including x-ray, gamma ray, and particle radiation for radiographic imaging, and nuclear medicine and x-ray mammography in particular, and material composition analysis are described. A detection system employs fixed or configurable arrays of one or more detector modules comprising detector arrays that may be electronically manipulated through a computer system. The detection system, by providing the ability for electronic manipulation, permits adaptive imaging. Detector array configurations include familiar geometries, including slit, slot, plane, open box, and ring configurations, and customized configurations, including wearable detector arrays, that are customized to the shape of the patient. Conventional, such as attenuating, rigid geometry, and unconventional collimators, such as x-ray optic, configurable, Compton scatter modules, can be selectively employed with detector modules and radiation sources. Novel Compton gamma camera designs can be implemented.
