QA Phantom for Arc Therapy and Field Abutment Verification.

The Phantom was designed to provide a means of verification for abutting fields and gaps using film. 

This is an acrylic phantom that is split in half to accommodate an 8 x 10" or 10 x 12" film.  There are four aluminum screws that are tightened after film placement to keep the film from moving and keep the phantom halves aligned.  The phantom has springs loaded into the screw holes which cause the phantom halves to separate when the screws are loosened.  One end of the phantom has a scale for rotation on each half of the phantom.  One scale goes from 0˚ to 180˚ with 30˚, 60˚, 90˚, 120˚ and 150˚ numbered and with markings at every 10˚.  The other scale goes from 180˚ to 360˚ and also has the 10˚ markings with numbers at 210˚, 240˚, 270˚, 300˚ and 330˚.  The scales can be used to position the phantom to match the gantry angle.

The ends of the stand are acrylic plates that have a scribed line for alignment of the phantom.  Two wood dowels between the stand ends provide the phantom support which allows for rotation of the phantom and also give minimal radiation obstruction.  A rubber pad on the bottom of the acrylic end plates prevents the stand from moving.

This item can be customized or a chamber cavity can be added.  Contact RPDinc for customization.
