A tutorial for treatment

planning in radiation therapy

This tutorial on treatment planning is based on the Prism system. Prism is a radiation treatment-planning system (TPS) developed by the Radiation Oncology Department at the University of Washington, Seattle, Washington, USA. The system has been in clinical operation at the University of Washington since 1994.

The tutorial is divided into three main learning modules (see Figure 1a), with each module having four units (see Figure 1b).
The time frame for each learning module is about 3-4 hours.

The first unit of each learning module deals with the Prism program. Its aim is to introduce all the functions and skills required for the particular learning module.

The second unit comprises several tasks in which the student applies acquired knowledge leading to improved understanding of treatment planning.

The third and fourth unit of each module consist of a challenge and a quiz respectively, both with the intention to test whether the learning objectives of the module have been achieved.

Using this tutorial

The user is guided through the tutorial by using the “Next page”-button at the end of each page. Particular pages can be accessed quickly by selecting the desired content on the explorer bar on the left hand side.

In case you get stuck, the “Tips and tricks”-page might be helpful. The Prism User’s Reference Manual might also be useful for problems with Prism.

If you are not able to solve a problem or discover a problem with Prism, e.g. a crash, a note should be made on the Wiki (see the Treatment Planning Tutorial (PHYS407) link at the bottom of the page).
