Our SPECT research has two main areas. One is instrumentation development and the other is image reconstruction development. In instrumentation development, we are working on three projects that develop methods for (1) multi-pinhole small animal SPECT system calibration and normalization, (2) skew-slit collimation for small animal SPECT imaging, and (3) a(More)
T2-weighted carotid artery images acquired using the turbo spin-echo (TSE) sequence frequently suffer from motion artifacts due to respiration and blood pulsation. The possibility of using HASTE sequence to achieve motion-free carotid images was investigated. The HASTE sequence suffers from severe blurring artifacts due to signal loss in later echoes due to(More)
Temporal sampling of MRI Myocardial perfusion studies: Effects with three Analysis Methods EVR DiBella, H Bal, S Vijayakumar, CJ McGann, H Buswell Introduction: A time-series of images can be acquired to follow the time-varying distribution of an injected agent using, for example, dynamic SPECT, dynamic PET or dynamic MRI. One way of analyzing these images(More)
