Introduction: Myocardial Perfusion Imaging (MPI) remains a cornerstone of cardiovascular care with 8 million scans per year in the US. Relative to current SPECT technology, cardiac PET has improved sensitivity and specificity and allows for dynamic i

PURPOSE: In traditional multi-pinhole SPECT systems, image multiplexing — the overlapping of pinhole projection images — may occur on the detector, which can inhibit quality image reconstructions due to photon-origin uncertainty. One proposed sys

BACKGROUND: Despite growing interest in Coronary Microvascular Disease (CMVD), there is a dearth of mechanistic understanding. Mouse models offer opportunities to understand molecular processes in CMVD. We have sought to develop quantitative mouse im

Purpose: One approach to preclinical single-photon emission computed tomography (SPECT) imaging that provides both high resolution and high sensitivity is based on imaging a mouse inside a collimating tube; many magnified pinhole projection images fr

We are designing a dual-resolution pre-clinical SPECT system based on square-pinhole apertures for use in applications with a small field-of-view (FOV), such as cardiac imaging of mice. Square pinholes allow for increased sensitivity due to more effi

Ischemic heart disease remains a significant public health concern, accentuating the importance of basic research and therapeutic studies of small animals in which myocardial changes can be reproducibly detected and quantified. Few or no studies have

C-SPECT is a human cardiac SPECT system designed to acquire all necessary views for imaging simultaneously. The system uses slit-slat collimation focused on a cylindrical region with the capability of identifying the heart either through a scout or t

To assess myocardial blood flow (MBF) in mice, and subsequently coronary microvascular function, we have previously developed a non-invasive, in-vivo, dynamic cardiac imaging protocol using the U-SPECT+ system. This work investigates microSPECT quant
