In this project I helped Mevion design their next generation of proton accelerator (called HyperScan & Adaptive Aperture) for cancer therapy. I wrote a simulation of various designs of the machines and calculated the radiation dose which would be delivered to the caner tumor, as well as the accidental dose delivered to adjacent healthy tissue.

A treatment is a series of spots.

Mechanical Simulation
In this simulation we see the proton beam (lower left panel - as a vector) passing through various control plates. The upper three panels show the location of the adaptive aperture (multi-leaf collimator). The lower right panel shows the dose-spots as delivered to the tumor.

Radiation Dosage Simulation
In this simulation we see the radiation being delivered. The red outlined "rainbow" is the target tumor area. The upper panels are the accumulated dosage. The lower panels are the instantaneous dosage.

DICOM Decoding
In order to correctly simulate the proton beam passing through the body I needed to know the density of the tissues in the body. I was given a "DICOM" file, a 3d medical image file from an MRI. I wrote a decoder and a visualizer to make sure we handled this data correctly. This is a scan from the shoulders to the top of the head. The tumor is at the top of the spinal cord.
