These instructions provide guidelines for preparing manuscripts for submission to the Conference Record (CR) of the 2016 IEEE Nuclear Science Symposium and Medical Imaging Conference. If you are using Microsoft Word to prepare your manuscript, you should use this document as a template. Define all symbols used in the abstract. Do not cite references in the abstract. Do not delete the blank line immediately...
A GEANT4 simulation of the phase II proton CT (pCT) scanner built by the pCT collaboration was used in order to study the spatial resolution of the imaging system. A digital edge phantom composed of water-equivalent polymer with 6 body-equivalent material inserts was created. A modified version of the oversampling method was used in order to construct edge spread functions and modulation transfer...
We present algorithms for the proton track reconstruction for the Phase II proton CT scanner designed and built by the pCT collaboration. The entrance and exit telescopes of the scanner consist of four planes of silicon sensors with horizontal and vertical strips for proton track reconstruction. The goal of the track reconstruction is to allow usage of submillimeter voxels for subsequent image reconstruction...
We report on the first beam test results with our pre-clinical (Phase-II) head scanner developed for proton computed tomography (pCT). After extensive preclinical testing, pCT will be employed in support of proton therapy treatment planning and pre-treatment verification in patients undergoing treatment with particle beam therapy. The Phase-II pCT system consists of two silicon-strip telescopes that...
Proton radiography has applications in patient alignment and verification procedures for proton beam radiation therapy. In this paper, we report an experiment which used 200 MeV protons to generate proton energy-loss and scattering radiographs of a hand phantom. The experiment used the first-generation proton computed tomography (CT) scanner prototype, which was installed on the research beam line...
Proton radiography generates two-dimensional projection images of an object and has applications in patient alignment and verification procedures in preparation for proton beam radiation therapy. The quality of the image, both contrast and spatial resolution, is likely to be affected by the energy of the protons used in the creation of the radiograph, as well as by multiple Coulomb scattering and...
We report on the development of a range counter to be used in a new head scanner developed for proton Computed Tomography (pCT) in support of proton therapy treatment planning. The scanner consists of two silicon telescopes which track the proton before and after the phantom/patient, and an energy detector which measures the residual energy or range of the proton to reconstruct the Water Equivalent...
We continue our timing measurements of Silicon Photomultipliers (SiPM) at the picosecond level at Fermilab.. We using SiPMs readout based on Ortec system, also as on fast waveform digitizer DRS4 [1]. SiPM's signal pulse shape was investigated. The single photoelectron time resolution (SPTR) was measured for the signals coming from the SiPM's. Dependence of the SPTR on the SiPms size was measured....
