The USC Radiation Oncology Physics Division has developed its own advanced 3D medical imaging and radiation treatment planning software for both external beam and brachytherapy treatment. The Physics faculty of the USC Department of Radiation Oncology are continually developing and improving powerful and cost-effective software for 3D radiation treatment planning. Most of our software is designed to run on our department's network of PowerPC Macintosh computers. Development and demo versions of our latest versions may be downloaded from these pages for the convenience of our remote "beta" testers and prospective new users.

These files are binhex4 encoded self-extracting archives, They are downloaded as text and require a binhex4 decoder program, such as "Stuffit Expander" on your Mac. They are also available for anonymous downloading from /Pub on our ftp server. E-mail astrahan@hsc.usc.edu for information on how to access our ftp server.

Medical Imaging (Macintosh)

The RT Simulator is used for general-purpose 3D visualization and treatment planning for cancers anywhere in the body. It allows physicists and physicians to precisely define and target the tumor, and then design dose distributions which conform precisely to the shape and location of the tumor.

Virtual Simulation and Digital Radiography is a process in which detailed 3D models of our patients are built from dozens or sometimes hundreds of closely spaced transverse CT (or MRI) images.

Plaque Simulator is designed for 3D treatment planning of radioactive I-125 "plaque" therapy for eye tumors such as choroidal melanoma in adults and retinoblastoma in young children.

MU Calculator

The MU Calculator provides a rapid solution for getting radiation therapy treatments started ASAP. Full 3D planning is later developed for each patient.

Gap Calculator

Gap Calculator is an application for PalmOS handheld computers which calculates the skin gap between two adjacent (and diverging) radiotherapy fields matched at depth for dose uniformity.

TDF Calculator

TDF Calculator is an application for PalmOS handheld computers that implements the linear-quadratic model to compare different radiotherapy fractionation regimens. TDF Calculator and the tutorial below implement the model calculations found in Time, Dose, and Fractionation in Radiotherapy, chapter 22 in Radiobiology for the Radiologist, Fifth Edition, by Eric J. Hall, Lippincott Williams & Wilkins, Philadelphia, 2000, pp 397-418.

Medical Image Viewer and Image Processing

Madena is a medical image viewer and image-processing program. Madena can open all QuickTime compatible image file formats as well as most Digital Imaging and Communications in Medicine (DICOM) and ACR/NEMA file formats. DICOM is the current industry standard for medical images and is widely used for CT, MR and US images. No additional drivers or licenses are required.
