Phantom for MOSFET Dosimeters & Superimposed Film / Ion Chamber
>5 Absolute Dose Points
The XWU-IMRT Phantom is ideal for obtaining qualitative dose measurements for film and MOSFET dosimetry. This 20 x 20 cm block phantom houses film and nine or more MOSFET dosimeters on two orthogonal planes.

One of the planes, containing five MOSFET detection points, is the dividing plane of the two sub-phantoms where a film is housed. Five absolute MOSFET dose points on the plane of the film provide dose verification. Easy to use cassettes come with pre-manufactured slots for the dosimeters and allow for greater versatility.

Advanced Applications: IMRT
Reliable and efficient MOSFETs are well suited for Quality Assurance in IMRT programs because they provide quantitative dose measurements. Due to their small size and excellent isotropic response, MOSFETs can be positioned in the XWU-IMRT Phantom for treatment planning QA of IMRT procedures. This can be done with single dosimeters or with the Linear 5ive Array, both in the phantom and on the patient.
