We have developed a dual-modality CT/SPECT imaging system for small-animal imaging
applications. The X-ray system comprises a commercially available micro-focus X-ray tube …

This paper presents the design and feasibility study of a very-high resolution gamma camera
for detecting 27-35 keV X and gamma rays emitted by I-125 labelled radiotracers. This …

Pinhole collimation is widely recognized for offering superior resolution-sensitivity trade-off
in SPECT imaging of small subjects. The newly developed EXIRAD-3D autoradiography …

High-resolution single-photon emission computed tomography (SPECT) imaging in small
animals tends to use long imaging times and large injected doses due to the poor sensitivity …

Channel-edge pinhole designs have been proposed in order to reduce the penetration of
gamma rays through the edge of the pinhole aperture. A characterization of penetration and …

The field of diagnostic radiology encompasses a wealth of imaging techniques that now are
essential for evaluating and managing patients who need medical care. Traditional imaging …

Pinhole SPECT often provides an excellent resolution sensitivity trade-off for radionuclide
imaging compared to SPECT with parallel holes, particularly when imaging small …

Silicon double-sided strip detectors offer outstanding instrinsic spatial resolution with
reasonable detection efficiency for iodine-125 emissions. This spatial resolution allows for …

Stationary small-animal SPECT systems are being developed for rapid dynamic imaging
from limited angular views. This work quantified, through simulations, the performance of …

The purpose of this study was to investigate an optimal readout for a high-resolution
compact gamma camera with maximum performance in crystal element identifications. The …
