Features
- Makes it possible to check the monitor calibration by inserting an ionization chamber into a hole of the acrylic block
- Slides into the accessory tray of the LINAC
The MONICHECK test object is an acrylic device to check the constancy of the dose monitor calibration of linear accelerators easily, which is the most important parameter for correct patient treatment. The basic component is an acrylic block with a hole to insert a 0.3 cm3 ionization chamber model 31003/31013. Adapters for other chamber types are available upon request. The chamber is connected to a dosemeter such as the UNIDOS. The measuring depth of the chamber is 16 mm or 33 mm depending on the orientation of the acrylic block. The block is mounted to an appropriate plate, which is inserted into the accelerators accessory holder. The type of the accelerator has to be specified, since the mechanical design of the accessory holder geometry differs with the type of linear accelerator. For constancy tests, the measuring results are compared with previous measurements under identical irradiation conditions.
