MD R&D is an initiative that aims to develop medical quality control equipment, especially radiotherapy. Most cancer patients receive radiotherapy at some stage of their treatment, and the quality controls of medical linear accelerator (LINAC) devices used for radiotherapy directly affect the success of the treatment. With the developed User Free Control (UFC) device, both mechanical and dosimetry quality controls of LINAC devices can be performed quickly, accurately, sensitively and independently of the user.
