摘要： Methods and systems for calibrating a nuclear medicine imaging system are provided. One method includes acquiring spatially determined non-uniform radiation flux information from a calibration scan of a calibration source using a gamma camera having an attached non-parallel-hole collimator. The method further includes determining a measured non-uniform count density profile from the acquired non-uniform radiation flux information. The method also includes creating a gamma camera uniformity correction map derived from (i) the measured non-uniform count density profile and (ii) a modeled or calculated non-uniform count density profile for calibrating the NM imaging system.

摘要： A method and a device for performing stack operations within a processing system. A first and second stack pointers point to a top of a stack and to a memory location following the top of the stack. A first stack pointer is used during pop operations and a second stack pointer is used during push operations. When a stack pointer is selected, it replaces the other stack pointer. The selected memory pointer is provided to a memory module in which a stack is implemented, and is also updated. When a pop operation is executed the updated stack pointer points to a memory location preceding a memory location pointed by the selected stack pointer and when a push operation is executed the updated stack pointer points to a memory address following that address.

摘要： Systems and methods for nuclear medicine (NM) imaging using different radiopharmaceuticals are provided. One method includes generating images of a region of interest (ROI) from radioactive emissions from a localization radiopharmaceutical to position the ROI in a field-of-view (FOV) of a gamma camera based on the generated images of the ROI. The method further includes performing an imaging scan of the ROI using an imaging radiopharmaceutical to acquire image data of the ROI, wherein the imaging radiopharmaceutical is different than the localization radiopharmaceutical.

摘要： A power saving device and method for either adding or subtracting a constant from an operand, by checking a logic value of a portion of the operand and deciding whether to activate a multi-bit adder or to perform the subtraction or addition by inverting a portion of the operand. The power saving device and method is especially efficient when the constant K equals 2n. Then, the n'th bit of the operand is checked and if the addition or subtraction operation can be performed by inverting the n'th bit of the operand, a result is generated by that inversion, while a multi-bit adder is disabled.
