A Comparison of Proton Stopping Power Measured with Proton CT and x-ray CT in Fresh Post-Mortem Porcine Structures
Don F. DeJongh, Ethan A. DeJongh, Victor Rykalin +13
Purpose: Currently, calculations of proton range in proton therapy patients are based on a conversion of CT Hounsfield Units of patient tissues into proton relative stopping power.…
Analysis of characteristics of images acquired with a prototype clinical proton radiography system
Christina Sarosiek, Ethan A. DeJongh, George Coutrakon +8
Verification of patient specific proton stopping powers obtained in the patient treatment position can be used to reduce the distal margins needed in particle beam planning. Proton…
Technical Note: A fast and monolithic prototype clinical proton radiography system optimized for pencil beam scanning
Ethan A. DeJongh, Don F. DeJongh, Igor Polnyi +9
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…
A Real-time Image Reconstruction System for Particle Treatment Planning Using Proton Computed Tomography (pCT)
Caesar E. Ordoñez, Nicholas Karonis, Kirk Duffin +4
Proton computed tomography (pCT) is a novel medical imaging modality for mapping the distribution of proton relative stopping power (RSP) in medical objects of interest. Compared t…
Results from a Prototype Proton-CT Head Scanner
R. P. Johnson, V. A. Bashkirov, G. Coutrakon +8
We are exploring low-dose proton radiography and computed tomography (pCT) as techniques to improve the accuracy of proton treatment planning and to provide artifact-free images fo…
