Medical Physics Web Applications

This page lists some web applications designed to help explore medical physics concepts further. Using these apps you can simulate and visualize different concepts and technologies regarding physics in medicine. To understand more about how these work, take a look at the medical physics tutorials as well as the labs. You can also visit the source code pages to see the code that runs these apps.

Simulation Tools

Planner 2D

Planner 2D image In external beam radiation therapy (EBRT), a medical linear accelerator generates beams of photons to deposit radiation dose in a target (or tumor). Use the Planner 2D app to plan simple photon treatments and learn more about EBRT.

Brachy 2D

Brachy 2D image In brachytherapy treatments, a radioactive source is placed inside the patient, using an applicator, to deposit radiation dose in a target (or tumor). Use the Brachy 2D app to learn more about brachytherapy by planning simple treatments.

RayCT Lite

RayCT Lite image Computed tomography (CT) imaging is used often to diagnose (or detect) a wide vareity of diseases, and can also be used to plan radiation therapy treatments. Learn about CT imaging by simulating CT scans and viewing the resulting images.

Data Analysis Tools

TASMIP Spectra Calculator

TASMIP spectra image Learn more about the radiation sources used for x-ray imaging (for example CT imaging). You can use this app to calculate and visualize the energy spectra for x-ray sources that use a tungsten anode.

NISTX Calculator

Attenuation coefficient plot Both x-ray imaging and radiation therapy depend on how x-rays (or photons) interact with the human body. This is defined mathematically using photon attenuation coefficients. You can use this application to calculate photon attenuation coefficients for any material from the NIST website.
