Diagnostic management system MLC QA

for radiation therapy

The quality management of radiotherapy machines ensures the safe and accurate operation of the equipment. These crucial procedures are essential for the reliability and efficiency of diagnostic and therapeutic interventions for patients, thereby ensuring quality care in the field of radiotherapy. The multileaf collimators (STATIC, IMRT, VMAT) To address the quality control of multileaf collimators, we offer the MLC QA Pack. For this pack, we follow these recommendations: The French decision of July 27, 2007, which establishes the internal quality control procedures for external radiotherapy installations. The French decision of February 28, 2023, fixing the modalities of quality control for external radiotherapy and radiosurgery installations.
