Introduction:SURGEOSIGHT is a dedicated intra-operative hand-held gamma camera designed and manufactured by our team to be used for lymphoscintigraphy. Although conventional gamma cameras are widely used, they lack the capability of the sentinel lymph node (SLN) imaging in the operation room. Like conventional gamma cameras it is necessary to calibrate SURGEOSIGHT for linearity...

objective(s):lutetium-177 can be made with high specific activity and with no other isotopes of lutetium present, referred to as “no carrier added” (nca) 177lu. we have radiolabelled dota-conjugated peptide dota‐(tyr3)‐octreotate with nca 177lu (“nca-lutate”) and used it in nearly 40 therapeutic administrations for subjects with neuroendocrine tumours or meningiomas. in this paper, we report on...

Detection of scattered gamma quanta degrades image contrast and quantitative accuracy of single-photon emission computed tomography (SPECT) imaging. This paper reviews methods to characterize and model scatter in SPECT and correct for its image degrading effects, both for clinical and small animal SPECT. Traditionally scatter correction methods were limited in accuracy, noise properties and/or ...

A prototype of the MeV gamma-ray imaging camera based on the full reconstruction of the Compton process has been developed. This camera consists of a micro-TPC that is a gaseous Time Projection Chamber (TPC) and scintillation cameras. With the information of the recoil electrons and the scattered gamma-rays, this camera detects the energy and incident direction of each incident gamma-ray. We de...

The Whipple collaboration pioneered the Imaging Atmospheric Cherenkov Technique (IACT) for the detection of Very High Energy (VHE) gamma rays. The Whipple 10 m gamma-ray telescope was located at the Fred Lawrence Whipple Observatory in Southern Arizona in the United States. The predecessor to VERITAS (Very Energetic Radiation Imaging Telescope Array System), this telescope was in operation from...

Abstract Cascade nuclides emit two or more gamma rays successively through an intermediate state. The coincidence detection of cascade provides several advantages in gamma-ray imaging. In this review article, three applications the double photon method are reviewed. Double-photon emission imaging with mechanical collimators and Compton double-photon can identify radioactive source positions the...

Introduction: Electronic portal imaging devices (EPIDs) could potentially be useful for intensity-modulated radiation therapy (IMRT) and VMAT QA. The data density, high resolution, large active area, and efficiency of the MV EPID make it an attractive option. However, EPIDs were designed as imaging devices, not dosimeters, and as a result they do not inherently measure dose in ...

We introduce neutron-gamma emission tomography (NGET) for the 3D imaging of special nuclear materials (e.g. plutonium, uranium).
