A stopping criterion for iterative proton CT image reconstruction based on correlated noise properties
Ethan A. DeJongh, Alexander A. Pryanichnikov, Don F. DeJongh +1
Background: Whereas filtered back projection algorithms for voxel-based CT image reconstruction have noise properties defined by the filter, iterative algorithms must stop at some…
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.…
An Iterative Least Squares Method for Proton CT Image Reconstruction
Don F. DeJongh, Ethan A. DeJongh
Clinically useful proton Computed Tomography images will rely on algorithms to find the three-dimensional proton stopping power distribution that optimally fits the measured proton…
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…
