3D Image Reconstruction from Compton camera data
In this paper, we address analytically and numerically the inversion of the integral transform (cone or Compton transform) that maps a function on R 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 called Compton cameras are involved. Several inversion formulas are deve...
متن کامل3 D image reconstruction for a Compton SPECT camera model 1
In this paper we propose a 3D image reconstruction algorithm for a 3D Compton camera being developed at the University of Michigan. We present a mathematical model of the transition matrix of the camera which exploits symmetries by using an adapted spatial sampling pattern in the object domain. For each projection angle, the sampling pattern is uniform over a set of equispaced nested hemisphere...
متن کاملTowards direct reconstruction from a gamma camera based on Compton scattering
The Compton scattering camera (sometimes called the electronically collimated camera) has been shown by others to have the potential to better the photon counting statistics and the energy resolution of the Anger camera for imaging in SPECT. By using coincident detection of Compton scattering events on two detecting planes, a photon can be localized to having been sourced on the surface of a co...
متن کامل3-D Reconstruction of Images from a Miniature Camera
A wireless implantable image sensor is advantageous for small bowel endoscopy or other subcutaneous monitoring due to the lack of lead wires that will impede motion or raise complication risks. However, to decrease the size of the implanted sensor, power to the device must be delivered wirelessly since batteries typically occupy a significant area. This leads to the need to decrease the power c...
متن کاملOptimization of a parallel hole collimator/CdZnTe gamma-camera architecture for scintimammography.
PURPOSE Small field-of-view CdZnTe (CZT) gamma cameras are increasingly studied for breast lesion detection to complement mammography or ultrasonographic findings. However, in classical collimation configurations, they remain limited by the trade-off between spatial resolution and sensitivity. The HiSens architecture was proposed to overcome these limitations. Using an accurate 3D localization ...
