## Abstract

A stabilization bar and a stabilization method for stabilizing patients during radiation therapy treatment.

## Claims

### Claim 1

A method of immobilizing a patient's body for radiation therapy medical treatment using computed tomography equipment wherein said computed tomography equipment has at least a table, said method comprising:
i attaching a locator bar to said computed tomography table;
ii mounting a stabilizer bar on said locator bar said stabilizer bar having a predetermined length and predetermined outside dimensions, said stabilizer bar having at least one flat surface and said flat surface having at least two spaced-apart openings therein;
iii placing an immobilization device over said stabilizer bar;
iv placing said patient's body in said immobilization device.

### Claim 2 (depends on 1)

A method as claimed in claim 1 wherein the immobilization device is a foamed immobilization device.

### Claim 3 (depends on 1)

A method as claimed in claim 1 wherein the immobilization device is a vacuum bag.
