摘要： A patient (14), at rest, is injected with a first isotope tracer. After a first uptake period, the patient is stressed and injected with a second isotope tracer. After a second isotope tracer uptake period, first and second isotope imaging data are concurrently detected by data acquiring devices (16). The first and second isotope imaging data are reconstructed into a first or rest state image, a second or stressed state image, and optionally a combined first and second isotope image. The image with the better image statistics is segmented to generate segmentation parameters, which segmentation parameters are applied to both the first or rest and second or stressed state images. In this manner, an image whose image statistics may be too weak for accurate segmentation is accurately segmented by generating two inherently aligned images and applying the same segmentation parameters to both.

摘要： An imaging system (10) comprises at least one radiation detector unit (16) disposed adjacent a field of view (20) to detect and measure radiation from the field of view (20). The detector unit (16) includes multiple detection modules (18) which each detects radiation from a prespecified region of the field of view (20), each region being a fraction of the field of view. One or more pinholes (52) are associated with the detector unit (16). Each pinhole (52) receives radiation from the prespecified region of the field of view (20) and transmits radiation to one or more associated detection modules (18).

摘要： In a disclosed imaging method, the instantaneous speed or data acquisition dwell times of a detector head is optimized as a function of position along a path of the detector head around a subject. The optimization is respective to an expected radioactive emission profile of a region of interest that is less than the entire subject. The detector head is traversed along the path using the optimized instantaneous speed or data acquisition dwell times. During the traversing, imaging data are acquired using the detector head. The acquired imaging data are reconstructed to generate a reconstructed image of at least the region of interest. A gamma camera configured to perform the foregoing imaging method is also disclosed.

摘要： In a disclosed imaging method, the instantaneous speed or data acquisition dwell times of a detector head (14, 16) is optimized as a function of position along a path (P) of the detector head around a subject (S, SS, SXL). The optimization is respective to an expected radioactive emission profile (EPROI) of a region of interest (H, HS, HXL) that is less than the entire subject. The detector head is traversed along the path using the optimized instantaneous speed or data acquisition dwell times (40). During the traversing, imaging data are acquired using the detector head. The acquired imaging data are reconstructed to generate a reconstructed image of at least the region of interest. A gamma camera (10) configured to perform the foregoing imaging method is also disclosed.

摘要： A radiation imaging device suitable for SPECT or other nuclear imaging includes a detector (22) which receives radiation. A fan beam-slit collimator (20) is positioned adjacent a radiation receiving face (32) of the detector, intermediate the detector and a radiation source (12, 18). The collimator includes a plurality of slats (30) having a common focus. A body (44) adjacent the slats defines one or more elongate slits (46). The slit is arranged such that radiation passes through the slit and between the slats to the detector face. The body is at least substantially impermeable to the radiation. The fan beam-slit collimator (20) enables higher resolution or efficiency to be achieved from the detector.
