摘要： Attenuation correction data is obtained from one or more transmission sources to calculate the attenuation factors of a reconstruction area of an object being imaged by a nuclear medicine apparatus, such as a SPECT gamma camera. The transmission sources are capable of swiveling the direction of the transmission to correspond with the direction of capture of the gamma detectors. Additionally, the transmission sources are capable of linear movement to correspond with any linear movement of the detectors. The transmission sources are able to follow the same path as the detectors in order to determine the attenuation factors through the same reconstruction area being scanned by the detectors.

摘要： A method for optimizing imaging dwell time during nuclear imaging. A fast pre-scan is conducted over the angular range of imaging, with equal dwell time at each position. A statistical sub-sampling is conducted over a region of interest to a desired fraction of the acquisition time. The statistical sub-sampling is used to simulate a varying dwell time tomographic dataset according to a profile pre-generated by an analysis of patient specific anatomic or functional information. Reconstructed data with equal dwell time and with simulated adaptive dwell time are constructed and compared to generate a difference image, a parameter of interest of which is evaluated. If the parameter of interest is within an acceptable level, the reduced dwell time for the given angular position is established; otherwise, the fraction is varied and the process is repeated. Once dwell times are computed for all view angles, a full scan is conducted.

摘要： A radiographic three dimensional imaging apparatus capable of focusing on a center of rotation point, includes at least two gamma ray detectors, each having a radiation input face, with each detector positioned on a linear path, wherein each detector is movable along the detector's linear path, while simultaneously swiveling to maintain the detector's input face towards the rotation point. The apparatus allows for organ-targeted tomography as a virtual center of rotation can be placed arbitrarily with respect to a patient, constrained only by the physical limits of the detector motion.

摘要： A process for obtaining an attenuation map from a truncated transmission scan of an imaged object, by compensating for missing emission data as a result of truncation by using non-truncated emission data of the imaged object to derive “fill-in” emission data. The truncation-compensated emission data then is used to generate an attenuation map for correcting a reconstructed emission image for effects of attenuation.
