Compton camera based on Timepix3 technology
Journal of Instrumentation, 2018The Compton camera concept is based on the reconstruction of recorded Compton scattering events of incoming gamma rays. The scattering of primary gamma ray occurs in the first detector (called scattering detector—usually thin) recording the position and energy of the recoiled electron.

Compton-camera-based SPECT for thyroid cancer imaging
Journal of X-Ray Science and Technology: Clinical Applications of Diagnosis and Therapeutics, 2020Thyroid cancer is the most common type of endocrine-related cancer and the most common cancer in young women. Currently, single photon emission computed tomography (SPECT) and computed tomography (CT) are used with radioiodine scintigraphy to evaluate patients with thyroid cancer.

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2019
Abstract Compton cameras have been developed for almost fifty years in various fields (astronomy, medical imaging, safety and industrial inspections, etc.), employing different types of detectors. Their potential use has gained renewed interest with the emergence of high light yield scintillator crystals and silicon photomultipliers (SiPMs).

Performance evaluation of a pixellated Ge Compton camera
Physics in Medicine and Biology, 2011An ongoing project is being carried out to develop a high purity germanium (HPGe) Compton camera for medical applications. The Compton camera offers many potential advantages over the conventional gamma camera. The camera reported in this paper comprises two pixellated germanium detector planes housed 9.6 cm apart in the same vacuum housing. The camera

Image reconstruction from limited angle Compton camera data
Physics in Medicine and Biology, 2002The Compton camera is used for imaging the distributions of gamma ray direction in a gamma ray telescope for astrophysics and for imaging radioisotope distributions in nuclear medicine without the need for collimators. The integration of gamma rays on a cone is measured with the camera, so that some sort of inversion method is needed.
