A scintillation camera and computer assembly is described whereby clinical and research scintigraphic data can be processed by a computer through a videotape transfer system. This assembly can provide a full computer capability to hospital clinics which are not equipped with a computer but still require convenient and rapid data analysis. Tomographic and anatomical marker data can also be acces...

Dedicated γ-cameras based on pixelated scintillators have long been used for breast tumor imaging. Intercrystal scattering (ICS) increases the background counting rate and degrades the image quality when small crystal pixels are used. Because of the small size of applied collimators, scattered radiation and septal penetration are high, and therefore collimator characteristics must be carefully ...

Animals, such as Savannah sparrows and North American monarch butterflies, are able to obtain compass information from skylight polarization patterns to help them navigate effectively and robustly. Inspired by excellent navigation ability of animals, this paper proposes a novel image-based polarized light compass, which has the advantages of having a small size and being light weight. Firstly, ...

OBJECTIVE This study compared the 123I thyroid uptake measurements obtained from a gamma camera fitted with a low-energy all-purpose (LEAP) collimator to those obtained from a thyroid uptake probe and gamma camera fitted with a pinhole (PH) collimator. METHODS Thirty-one patients (27 female and 4 male patients) were studied for comparison between a probe and a gamma camera fitted with LEAP co...

The Daily intrinsic flood uniformity test of a gamma camera is required to be performed before using the gamma camera to acquire patient images. It is meant to detect changes in the performance of a gamma camera system that may affect the interpretation of clinical studies adversely.

UNLABELLED Paraaortic sentinel node biopsy may be a challenging procedure because the sentinel nodes are located retroperitoneally in close proximity to vital structures. The purpose of this study was to describe and evaluate the value of preoperative SPECT/CT for lymphatic mapping, and a portable gamma-camera for intraoperative radioguidance, in patients with paraaortic sentinel nodes. METHO...
