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 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 study using a passive scattered beam
The use of high-energy proton beams enables to delivering high doses to target volumes, while sparing organs at risk compared to X-ray radiotherapy. However, the protons advantages cannot be fully exploited because the range (i.e the stopping powers) of protons in matter is not accurately known. Indeed, the proton stopping powers are obtained by an empirical conversion of X-CT Hounsfield Units ...
متن کاملProton energy and scattering angle radiographs to improve proton treatment planning: a Monte Carlo study
The novel proton radiography imaging technique has a large potential to be used in direct measurement of the proton energy loss (proton stopping power, PSP) in various tissues in the patient. The uncertainty of PSPs, currently obtained from translation of X-ray Computed Tomography (xCT) images, should be minimized from 3–5% or higher to less than 1%, to make the treatment plan with proton beams...

متن کاملInitial studies on proton computed tomography using a silicon strip detector telescope
We report initial results of a feasibility study of Proton Computed Tomography and Proton Transmission Radiography for applications in proton therapy treatment planning and patient positioning. The aim of the study is to explore experimentally if PCT, which is based on the measurement of the specific energy loss of protons traversing tissues of different density, may be preferred to X-ray Compu...
