PROTON RADIOGRAPHY EXPERIMENT BASED ON A 100 MeV PROTON CYCLOTRON*
A proof-of-principle test-stand for proton radiography is under construction at China Institute of Atomic Energy (CIAE). This test-stand will utilize the 100 MeV proton beam provided by the compact cyclotron CYCIAE-100, which has been built in the year of 2014, to radiograph thin static objects. The assembling of the test-stand components is finished by now. We will carry out the first proton r...
متن کاملWater-equivalent path length calibration of a prototype proton CT scanner.
PURPOSE The authors present a calibration method for a prototype proton computed tomography (pCT) scanner. The accuracy of these measurements depends upon careful calibration of the energy detector used to measure the residual energy of the protons that passed through the object. METHODS A prototype pCT scanner with a cesium iodide (CsI(Tl)) crystal calorimeter was calibrated by measuring the...
متن کاملTitle: Proton radiography and tomography with application to proton therapy Short title: Proton radiography and tomography
Proton radiography and tomography have long promised benefit for proton therapy. Their first suggestion was in the early 1960s and the first published proton radiographs and CT images appeared in the late 1960s and 1970s, respectively. More than just providing anatomical images, proton transmission imaging provides the potential for the more accurate estimation of stoppingpower ratio (SPR) insi...
متن کاملProton radiography.
Energetic protons from an accelerator may be used to produce radiographs showing unusually high contrast but relatively poor spatial resolution.
متن کاملTracking Study of 200 MeV Protons within a PMMA Phantom
This paper describes an experiment that determined the position, and its associated uncertainty, of a proton at three different depths inside of a polymethyl-methacrylate (PMMA) absorber. These observed positions prove the fact that one can predict the most likely path (MLP) of a proton moving through a uniform medium, as long as the displacement and angle of that proton are known at the absorb...
