The authors have developed a single photon emission computed tomography (SPECT) technique for high resolution radiotracer imaging of mice where the object is rotated instead of the scintillation camera. The system uses a 21 cm focal length pinhole co

The authors have developed a new technique for compensating myocardial SPECT images for partial volume errors using coregistered X-ray CT images. The CT-derived myocardial mass defines a template that can be assigned unit activity and mathematically

We have developed and demonstrated an imaging system that couples an X-ray CT scanner to a scintillation camera for the localization and absolute measurement of radionuclide uptake. We use the registered CT images to provide physical information to o

The authors present experimental results for attenuation correction of emission tomography through use of an attenuation map derived from X-ray CT data. The X-ray and gamma-ray data were obtained from a third-generation X-ray CT scanner and a single-

Concurrent Iterative Reconstruction Algorithms use projection data in the iterative process as the data become available during the SPECT acquisition process and continue iterations in the post-acquisition period as conventional iterative algorithms.

An image registration technique that can be used to register microCT and microSPECT images acquired with a high-resolution dual-modality SPECT/CT small animal imaging system is being developed. External fiducial markers containing droplets of the K/s

Increased inferior activity in attenuation-corrected myocardial images has been attributed to scatter from the liver. To study this effect, the authors used EGS4 to simulate the SPECT acquisition of a 1.5-cm thick spherical shell placed inside a 24-c
