Three-Dimensional Image Reconstruction from Compton Camera Data
SIAM Journal on Imaging Sciences, 2016Summary: In this paper, we address analytically and numerically the inversion of the integral transform (cone or Compton transform) that maps a function on \(\mathbb{R}^3\) to its integrals over conical surfaces. It arises in a variety of imaging techniques, e.g., in astronomy, optical imaging, and homeland security imaging, especially when the so ...

Performance evaluation of MACACO: a multilayer Compton camera
Physics in Medicine & Biology, 2017Compton imaging devices have been proposed and studied for a wide range of applications. We have developed a Compton camera prototype which can be operated with two or three detector layers based on monolithic lanthanum bromide ([Formula: see text]) crystals coupled to silicon photomultipliers (SiPMs), to be used for proton range verification in hadron

2003 IEEE Nuclear Science Symposium. Conference Record (IEEE Cat. No.03CH37515), 2003
To bring a breakthrough in the observation of the gamma-ray universe, we are working on the development of Semiconductor Multi-Compton Telescope(SMCT). In the SMCT, all the energy, positional and timing resolution must be high to ensure high sensitivity. The imaging device based on the high resolution CdTe diode and Si, such as CdTe pixel detectors and

Gamma-ray imaging with Compton cameras
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1995Abstract Compton cameras use the kinematics of Compton scattering to construct a source image without the use of collimators or masks. Compton telescopes were first built in the 1970s for astronomical observations. The first laboratory instrument was designed for medical imaging.

Production of 95mTc for Compton camera imaging
Journal of Radioanalytical and Nuclear Chemistry, 2014With the development of the Compton camera which can realize high position resolution, technetium isotopes emitting high energy gamma-rays are required. In this study, Technetium-95m which emits some gamma rays with higher than 200 keV was produced by the 95Mo(p,n)95mTc reaction. Image of gamma-rays from 95mTc was taken by a Compton gamma-ray camera.

Stochastic image reconstruction method for Compton camera
2009 IEEE Nuclear Science Symposium Conference Record (NSS/MIC), 2009Compton camera has been proposed as an imaging tool in astronomy, industry, homeland security and medical imaging where source location can be identified based on detection of Compton scattered and photoabsorbed photons. However, due to the geometrical complexity of the problem, image reconstruction from Compton camera data is difficult and/or ...

3D reconstruction optimization for compton camera events
2015 IEEE Nuclear Science Symposium and Medical Imaging Conference (NSS/MIC), 2015Due to the nature of the Compton Camera operation, the detection efficiency for distributed γ-sources is strongly affected by the angular acceptance and the interaction probability of the photon for a given tracer energy. In order to overcome imposed artifacts and other deformation effects in the final image, an optimization method for the ...

Reconstruction of Compton Camera Images
2011The necessity of studying the targeting capability of pharmaceuticals in oncology brought to the development of different imaging techniques. Some examples are Positron Emission Tomography (PET) and Single Photon Emission Computed Tomography (SPECT), which involve the detection of gamma-rays emitted from radio-isotope markers.

Performance evaluation of the UCL Compton camera
IEEE Nuclear Science Symposuim & Medical Imaging Conference, 2010An 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 other imaging modalities used in nuclear medicine. These advantages include a wide field of view, the ability to reconstruct 3D images without tomography, and the fact that ...
