Description

We will be discussing the following two papers about the Planning Target Volume Tool in class next Wednesday:

• Kromhout-Schiro, Austin-Seymour, & Kalet - A Computer Model for Derivation of the Planning Target Volume from the Gross or Clinical Tumor Volume: PS or PDF
• Ketting, et al. - Evaluation of an Expert System Producing Geometric Solids as Output: PS or PDF

To prepare yourself for the discussion, write short responses to the following points:

1. A brief description of the purpose, inputs, and outputs of the PTVT.
2. We touched briefly on evaluation (the Turing Test). Did the evaluation methodology appear to be sound? Can you think of alternatives?
3. The evaluation addressed whether the tool output was acceptable to experts. This is different from determining whether the program is doing the calculation correctly, i.e., according to the model. How would you address this latter problem?
4. What would seem to be the consequences of errors in the output of this tool? Could the user of it identify such errors and correct them?

Guidelines

Your responses are due (on paper) at the beginning of class on August 8. The assignment will be worth 5 points. As with Homework 3, please bring two copies of your answers to class -- one to hand in at the beginning and one to use for reference during class discussion.

Questions & Clarifications

Please write with any questions, and we'll post clarifications here.
