PURPOSE Verification of patient specific proton stopping powers obtained in the patient's treatment position can be used to reduce the distal and proximal margins needed in particle beam planning. Proton radiography can be used as a pre-treatment instrument to verify integrated stopping power consistency with the treatment planning CT. Although a proton radiograph is a pixel by pixel representation of integrated stopping powers, the image may also be of high enough quality and contrast to be…

Low Intensity Beam Extraction Mode on the Protom Synchrotron for Proton Radiography Implementation
Proton radiography is one of the most important and actual areas of research that can significantly improve the quality and accuracy of proton therapy. Currently, the calculation of the proton range
A Comparison of Proton Stopping Power Measured with Proton CT and x-ray CT in Fresh Post-Mortem Porcine Structures.
The potential for proton CT to be used for low-dose treatment planning with reduced margins is demonstrated with complex porcine samples and close in time x-ray CT scans of the same samples, and proton stopping power measurements from the two modalities are compared.


Proton radiography as a tool for quality control in proton therapy.
It is found that the precision in range can be improved by a detailed analysis of the calibration data obtained from tissue-substitute measurements, by a factor of 2.5.
Proton radiography with a commercial range telescope detector using dedicated post processing methods.
This work suggests that proton radiographies with good WET accuracy can be obtained with a reasonable experimental effort that would facilitate integration into clinical routine.
Fast in situ image reconstruction for proton radiography
It is demonstrated, through computer simulations of proton irradiation of a pediatric head phantom using the newly built pRad detector and image reconstruction software, that high-quality proton radiographs can be generated for patient alignment and verification of water equivalent thickness of the patient before each treatment.
Image reconstruction and Monte Carlo simulations in the development of proton computed tomography for applications in proton radiation therapy
Proton therapy is a rapidly expanding form of cancer treatment. Because protons have a finite range in matter, this treatment modality allows for a greater degree of conformality than conventional
Technical Note: A prototype clinical proton radiography system
Purpose: To demonstrate a proton imaging system based on well-established fast scintillator technology to achieve high performance with low cost and complexity, with the potential of a

This review introduces hadron therapy and the perceived advantages of pCT and proton radiography for treatment planning, reviews its historical development, and discusses the physics related to proton imaging.
Software platform for simulation of a prototype proton CT scanner
The validated pCT software platform is a versatile tool for clinical proton CT performance and application studies in a virtual setting and can be modified to simulate not yet existing versions of pCT scanners and higher proton energies than those currently clinically available.
Proton radiography and tomography with application to proton therapy
This review introduces the principles of proton radiography and tomography, their historical developments, the raft of modern prototype systems and the primary design issues.
Proton range verification using a range probe: definition of concept and initial analysis.
The concept of the proton 'range probe', a low-dose, high-energy proton pencil beam that would pass through a patient, and whose integral Bragg peak would be measured on the exit side using a multi-layer detector, appears to be feasible for high-resolution range verification.
In vivo proton range verification: a review.
In this review, state-of-the art in vivo proton range verification methods currently being proposed, developed or clinically implemented are described and compared.
