Nik Kamarullah Bin Ya Ali
Medical Physicist (Radiology)
Department of Radiology, HUSM.
Works under Supervision of Senior Medical Physicist,
Professor Dr Wan Ahmad Kamil Wan Abdullah.
General Responsibilities
- The Medical Physicist plays an important role in the quality assurance of equipment and ensuring optimum image quality.
- The Medical Physicists protect the patient from over-exposure to ionising radiation, make sure that the equipment is running properly and is being utilized correctly in the diagnosis or treatment of a patient.
- For applications involving ionising radiation, the medical physicist is crucial in ensuring that the dose to the patient is the minimum possible while achieving images of diagnostic quality.
- Involved as a member in Radiation Protection Committe (RPC) HUSM.
- Organize all licensing requirements by the Ministry of Health.
- Create tender specification, review tender submission and help in the tender evaluation.
- Perform Testing & Commissioning (T&C) for all new irradiating apparatus and new x-ray rooms before vendor hand over the equipment for hospital usage.
- Guide and train medical technicians / medical radiation student in the department to do QC testing for irradiation apparatus as scheduled.
- Carry out dose monitoring for radiation workers, workplace and calibration of radiation monitoring devices, measuring leakage radiation and scatter radiation from the x-ray facility.
- Organize all activities regarding radiation protection & safety including training to radiation workers, public awareness and research study.
- Perform dose audit for patients who going for radiology examinations and develop internal Diagnostic Reference Level (Radiology) for HUSM.
- Teaching and presentation of continuing education programs for radiology residents, medical students, medical officers, mmed students, nurses, ancillary personnel and other staff.
- Performance of acceptance testing, calibration, and safety surveys of imaging and radiation radiology equipment and Participate in planning for future radiology facilities.
Quality Control Tests for Lead Gowns
Lead gowns are expensive
protective items that should be kept in good condition for as long as possible.
Apart from deterioration due to aging, very often lead gowns are damaged due
to incorrect handling. A lead gown(even with the latest improved material)
tends to crack when being folded, cross folding would even be worse.
When not in use, gowns should be
hung carefully on designated hangers or wrapped over a reinforced towel bar. Lead
gowns should be tested for defects at least every 12 months. The tests can be
carried out with a fluoroscopy unit or using conventional film/screen or
digital radiography.
