The development of low profile gamma-ray detectors has encouraged the production of small field of view (SFOV) hand-held imaging devices for use at the patient bedside and in operating theatres. Early development of these SFOV cameras was focussed...
Introduction
The first clinical study of targeted hybrid near-infrared (NIR) fluorescent-radioactive tracers was recently published. In addition, ICG-99mTc-nanocolloid is already being used by some centres for sentinel lymph node biopsy. Once...
Introduction
The development of compact low profile gamma-ray detectors has allowed the production of a small field of view, handheld imaging device which could be used at the patient bedside and in operating theatres. The combination of an optical...
A number of portable gamma cameras for medical imaging use scintillator-CCD based detectors. This paper compares the performance of a scintillator-CCD based portable gamma camera with either a columnar CsI:Tl or a pixelated GOS scintillator...
Objectives:
The Hybrid Gamma Camera (HGC) has been developed to enhance the localisation of radiopharmaceutical uptake in targeted tissues during surgical procedures such as sentinel lymph node (SLN) biopsy. To assess the capability of the HGC, a...
Purpose: Hybrid imaging has proven to be a major innovation in medical diagnosis. In nuclear medicine hybrid imaging allows the fusion of functional information with anatomical detail, however clinical studies have mainly been been carried out with...
Purpose: The development of small field of view (SFOV) gamma cameras for intraoperative imaging is an expanding area of research. Combining gamma and optical imaging in a co-aligned configuration is a new concept that could provide high spatial...
Purpose
The Hybrid Compact Gamma Camera (HCGC) has been developed to provide additional localisation information during procedures such as sentinel lymph node (SLN) biopsies. In this study, a lymph-node contrast (LNC) phantom and an evaluative...
Objective: To estimate the depth of radioisotope distribution in relation to patient anatomy using a portable hybrid gamma camera which combines optical and gamma imaging. This additional information could be of particular help in optimising...
Introduction
The development of portable mini gamma cameras in medical imaging offers new applications for intraoperative nuclear imaging. A new concept for a nuclear diagnostic imaging is presented, Hybrid Compact Gamma Camera (HCGC). This newly...
Introduction:
There is an increasing interest of the applications of handheld gamma cameras in sentinel lymph node biopsy (SLNB) in a broad range of cancers. A prototype hybrid optical-gamma camera has been developed through collaboration between...
A combination of an optical and a gamma camera, in a co-aligned configuration, offers high spatial resolution multi-modal imaging giving a superimposed scintigraphic and optical image. The hybrid Gamma Camera offers new possibilities for assisting...
The Hybrid Compact Gamma Camera (HCGC) is a portable optical-gamma hybrid imager designed for intraoperative medical imaging, particularly for sentinel lymph node biopsy procedures. To investigate the capability of the HCGC in lymphatic system...
Introduction:
Sometimes seeing things from the outside does not tell the whole story. It might look fine on the outside but inside all may not be well. With this in mind, nuclear diagnostic imaging is an area of radiology that allows physicians to...
Abstract: Over the last two decades advances in semiconductor detector technology have reached the point where they are sufficiently sensitive to become an alternative to scintillators for high energy gamma ray detection for application in fields...

Sometimes seeing things from the outside does not tell the whole story. It might look fine on the outside but inside all may not be well. With this in mind, nuclear diagnostic imaging is an area of radiology that allows physicians to...
This dissertation introduces methods to optimise the X-ray CT exposures within SPECT/CT studies. In this project I correlate between the body mass index BMI and the CT dose exposed to patients. In this project SPECT/CT lumbar spine for facet joint...
The development of compact low profile gamma-ray detectors has allowed the production of small field of view, hand held imaging devices for use at the patient bedside and in operating theatres. The combination of an optical and a gamma camera, in a...
Objectives
The Hybrid Compact Gamma Camera (HCGC) [1] has been developed to provide additional localisation information during procedures such as sentinel lymph node biopsies. These procedures trace radiopharmaceuticals, from an injection site to...
Introduction
The development of portable gamma cameras offers new applications for intraoperative imaging [1]. Multi-modality systems have a long heritage in nuclear medicine [2]. A multi-model gamma-optical system has been proposed as one...
