INSTRUCTIONS FOR SRS QUALITY AUDIT SYSTEM
Enclosed is a head phantom with two inserts; an imaging insert containing the "tumor," and a dosimetry insert
containing film and TLD.
The purpose of the phantom is to verify dose and dose distribution, as well as
localization of the dose relative to a simulated “tumor."
The imaging insert contains a nylon sphere suspended in water as the target volume (tumor).
The dosimetry
insert contains two orthogonal sheets of GAFchromic film passing through the center of the target and two
TLD within 0.5 cm of the center of the target (see the figure).
In order to ensure optimum precision of our evaluation, the following constraints should be observed in
planning the treatment:
The maximum dose to the film should be approximately 30 Gy.
The dose to the TLD (at the center of the target) should be approximately 30 Gy.
Our report to you will include the following:
The dose at the center of the target (nylon ball) measured by TLD.
Dose profiles measured by film.
Image, plan, and treat this phantom as if it were a real patient.
Please send us enough documentation so
we can tell what you have done.
Please follow the enclosed instructions and return the phantom and
paperwork as soon as possible.
