摘要： Emission tomography is registered with computed tomography or other modality in reconstruction. The anatomical information is used in the emission tomography reconstruction. In addition to an initial registration to use the anatomical information in the reconstruction, the registration is refined one or more times during other iterations refining the reconstruction of the emission volume. The registration is performed as part of the reconstruction. This multi-modal reconstruction may result in an emission tomography volume better aligned with the anatomical information.

摘要： Methods and apparatuses for quality control in image space for processing with an input data set are disclosed. A method includes providing an image object, including multiple voxels, and an input data set. A data model is determined from the image object. A cumulative distribution function (CDF) for the input data set is determined from the data model and the input data set based on a plurality of projections.

The output of the ICDF is displayed. A nuclear imaging system and a computer readable storage medium are also disclosed. Techniques disclosed herein facilitate efficient quality control for tomographic image reconstruction.

摘要： A method for tomographic nuclear imaging determines the distance between a non-parallel hole collimator surface and a region of interest (ROI) by obtaining difference images between images acquired at different view angles of the ROI. The distance may be used in a nuclear image reconstruction algorithm to more accurately reconstruct an image of the ROI. The method takes advantage of the non-stationary Point Spread Function of a non-parallel hole collimator to determine depth information of gamma events emitted from the ROI.
