Interactive Radiotheraphy

IRIS, a dynamic imaging radioscopic system with a high level of contrast and sensitivity, is used in cancer therapy to monitor the patient’s position during treatment with external beams.
IRIS improves the quality of the treatment and allows more accurate visualization for localization of the treatment area.
IRIS is independent from the accelerator builders. It is compact, can easily be integrated in any standard medical linear accelerator equipment and improves its performances. It produces, in real-time, up to 10 images per second, with a 16-bit resolution readout. IRIS uses a large area pixel matrix with a sensitive surface of 20 cm x 20 cm or 41 cm x 41 cm based on a solid state amorphous silicon detector.
The excellent quality of the images enables on-line identification and correction of small shifts of the treatment field and real-time monitoring of internal organ movements. As a result, the risk of irradiating healthy tissues diminishes and the treatment efficiency increases.
IRIS enables on-line mapping of the exit dose and recording of the delivered dose from one session to another. The high speed and quality of images make possible on–line beam modulation, collimator control and fast position adjustment. IRIS ensures quality control for IMRT.
The images are directly displayed on the PC monitor and archived in a digital form thanks to IRIS-View, a very userfriendly image processing software. Telemedicine is made possible: the medical information can be transferred through PACS or Internet networks.
