The Department of Medical Physics is responsible for the purchase, quality control, and optimal and safe operation of all radioactivity devices as well as for the design and calculation of radiotherapy in collaboration with the Radiologist Oncologist in the two linear accelerators installed at GOC, (Versa HD LINAC, Synergy LINAC) and the High Dose Rate Brachytherapy Unit (microSelectron HDR).
External Beam Radiotherapy
Medical Physicists are responsible for checking the proper functioning and calibration of linear accelerators (LINACs) with the aid of their measurement systems and following international reference protocols. In addition, they are responsible for checking the proper functioning of imaging systems incorporated in linear accelerators (iView, XVI), which allow image-guided Radiotherapy (IGRT).
The Medical Physics team performs the treatment planning for patients receiving Radiotherapy in collaboration with the Radiologist Oncologist and is responsible for the safe and accurate application of the treatment. Applying radiotherapy techniques in the Treatment Planning System (Monaco), such as Intensity Modulated Radiation Therapy (IMRT), Intracranial Stereotactic Radiation Therapy (SRS / SRT), Volumetric Modulated Arc Therapy (VMAT) allows the attending physician to achieve target dose escalation while protecting adjacent healthy tissues. In addition, by using independent dose calculation software and in vivo dose measurement systems (DoseCheck, perFraction) Medical Physicists ensure the accuracy of radiotherapy and control a variety of parameters related to the optimization of the therapeutic session.
Finally, the Department of Medical Physics controls the Therapy Management Software (Mosaiq) in collaboration with the IT department of the GOC.
High Dose Rate Brachytherapy
The Department of Medical Physics is responsible for the purchase handling and export of the Iridium-192 sealed radioactive sources, their activity measurement, and the quality control of the brachytherapy automatic remote afterloader system.
In addition, the department is responsible for the quality control of GOC brachytherapy, Oncentra Prostate planning systems as well as brachytherapy treatment planning as well as its implementation in collaboration with the Radiation Oncologists, with image guidance using either transrectal ultrasound, computed tomography (CT) and/or magnetic resonance imaging (MRI).
