Development of a two-layer dense-pixel LYSO Compton camera prototype for prompt gamma imaging
Physics in Medicine and Biology, 2023Objective. Lutetium–yttrium orthosilicate (LYSO)-based Compton camera (CC) has been proposed for prompt gamma imaging due to its high detection efficiency and position resolution.

The goal of the Compton camera imaging is to visualize the gamma-ray intensity map. Here, we focus on the case where the gamma-ray sources are sufficiently far from the camera and propose a new reconstruction method for the Compton camera imaging. The method is called the bin-mode estimation (BME).

Compton Cameras have been proposed as an alternative to SPECT imaging with Gamma Camera, mainly due to factors such as the electronic collimation, which allows a bigger field of view and provides further information from the acquired events if compared to devices with mechanical collimation.

Cameras shapes for medical imaging Compton cameras
SPIE Proceedings, 2010The shape of the detectors that comprise a Compton camera largely determines the geometric distribution of the set of data that is measured. It is our hypothesis that the geometric distribution of a set of data determines the informational contents of the data.

A Compton camera for multi-tracer imaging
2000 IEEE Nuclear Science Symposium. Conference Record (Cat. No.00CH37149), 2001A high-energy resolution Compton camera consisting of two segmented Ge detectors is proposed for multitracer research. The basic parameters affecting its spatial resolution are described. Monte Carlo simulations were performed to optimize the detector system. Its suitability for multitracer technology was demonstrated by a test experiment.

Abstract The SPEctroscopic Imager for γ - Rays (SPEIR) is a Compton scatter γ -ray imaging system of high efficiency and spectroscopic resolution with a 4- π field-of-view. The imaging system consists of double-sided segmented (DSSD) planar Ge detectors, an acquisition system instrumenting the detectors, and a set of data analysis methods.

A new modality of bidimensional Compton camera
2015 37th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2015The concept of Compton camera originates from the need to improve sensitivity in Single Photon Emission Imaging, which uses hole collimators. It advocates electronic collimation which registers radiation emitted by the radiating object and scattered by a scattering detector placed before an absorption detector.

Resolution recovery reconstruction for a Compton camera
Physics in Medicine and Biology, 2013The spatial resolution from Compton cameras suffers from measurement uncertainties in interaction positions and energies. The degree of degradation in spatial resolution is shift-variant (SV) over the field-of-view (FOV) because the imaging principle is based on the conical surface integration.

It is widely acknowledged that maximum a posteriori (MAP) estimation, when combined with a Markov random field (MRF) prior, is an effective tool for Compton camera imaging from Poisson data.
