CT Beam Width Tool Kit
The CTBW Tool Kit is used to make beam width measurements quickly and easily based on a new patent pending* technique. The toolkit includes three radiopaque masks of different sizes that are appropriate for measurement of standard CT machine beam widths. Dose measurements are made using a Radcal Accu-Gold family system equipped with a CT ion chamber. The mask fits securely over the chamber and measurements are performed with and without the mask in place. From these measurements alone the beam width is calculated with excellent precision. The mask is the only specialized equipment needed using this method, and no image analysis is required.
The kit includes three precision masks packaged in a compact zippered case. Each mask is engraved with its specifications.
