Our Services




Medical Physicists have specialised training in the medical applications of physics. They contribute specialist scientific and technical expertise and skills towards the diagnosis and treatment of individual patients as part of a multi-disciplinary team. Medical Physicists work in hospital diagnostic imaging departments or cancer treatment facilities.    

Medical Physicists specialise in one of three areas:

  • Diagnostic Radiology 
  • Nuclear Medicine 
  • Radiotherapy

Medical Physicists play an essential role in the safe medical use of many different types of radiation producing equipment and uses of radioactivity. The Medical Physicist will use specialised ​​equipment to measure and calculate the doses of radiation received by patients during their diagnostic imaging or treatment a​nd by the staff delivering it. The Medical Physicist will providing scientific and technical expertise on the design of radiation facilities, the safe handling, storage and disposal of radioactive materials and will also survey the working environment.

The Medical Physicist will also be involved in the specification, procurement, acceptance testing and quality control of complex and expensive medical equipment including radiotherapy linear accelerators and imaging equipment such as X-ray CT scanners and MRI scanners.

Back Office Process

Radiotherapy Medical Physics

Radiotherapy involves the use of radiation to kill cancer cells and shrink tumours. Radiotherapy often refers to external beam radiation therapy where the source of radiation is external to the body; on the other hand, brachytherapy is another radiotherapy modality whereby a source of radiation is implanted temporarily or permanently inside the body to treat cancer.

The involvement of Radiotherapy Medical Physicists in clinical practice is extensive, having a direct and pivotal role in patient care. The roles and responsibilities include dose optimisation for each radiotherapy patient treatment. The patient treatment request is received and an optimal dose delivery aimed at maximising dose to tumour and minimising doses to healthy tissues and other organs at risk is prepared. This is achieved through the application of dedicated software for dose calculation and optimisation. Furthermore, Radiotherapy Medical Physicists are responsible for the acceptance testing, commissioning and quality control of radiological equipment and other ancillary software such as treatment planning systems used for patient radiotherapy. Apart from linear accelerators, radiotherapy medical physicists are responsible for ionising and non-ionising imaging equipment and techniques integral to the patient radiotherapy process. These, together with the use of advanced dosimetry systems allow for the safe and accurate delivery of radiotherapy to patients. 

Radiotherapy Medical Physicists form part of a multi-disciplinary team and are closely involved with radiotherapy professionals to develop clinical techniques and optimize technological systems to implement improved therapeutic patient procedures.​​​

Nuclear Medicine

Nuclear medicine is the use of radioactive substances (such as radiolabelled pharmaceuticals) to help diagnose and treat patients. Medical Physicists may be engaged in manufacturing radiolabelled pharmaceuticals and then obtaining images and making measurements. They ensure that radioactive materials are purchased, used and disposed of safely and are involved in interpreting results and developing new procedures for both diagnosis and therapy.

Diagnostic & Interventional Radiology

Diagnostic & Interventional Radiology involves a wide range of high-tech medical imaging modalities: general projection X-ray imaging, mammography, diagnostic fluoroscopy, interventional and cardiology systems, computed tomography (CT), magnetic resonance imaging (MRI), ultrasound imaging (USI) and dental x-ray imaging. All these imaging modalities involve advanced physics. Medical Physicists provide the expert physics advice and troubleshooting necessary to ensure that they are used effectively (accurate diagnosis) and safely with patients and that the equipment is properly acceptance tested and quality assured. Medical Physicists work closely with radiologists, radiographers as well as with biomedical engineering to develop technical specifications and commissioning of new systems. Our role is to contribute to help improve patient outcome, save lives and reduce radiation damage to the genetic pool of the Maltese population.​​
