Consultant Medical Physicist

Job Code


Basic Function

Under the direction of the Supervisor of the Imaging Support Team, the employee will augment the existing diagnostic medical physics support services being provided to ensure safe use of JHAH diagnostic x-ray emitting devices, primarily in Radiology, but also may include: Urology, Catheter Lab and Dentistry. This would include but not be limited to: equipment procurement documentation development, modality acceptance testing & commissioning, quality control program development and annual testing, modality specific accreditation program implementation, equipment imaging chain troubleshooting with vendor service engineers and onsite clinical engineers, image/dose optimization studies, patient dosimetry measurements and Radiology staff technical development.


The employee will be based at the Johns Hopkins Aramco Healthcare (JHAH) Dhahran facility within Radiology Imaging Services of the Medical & Technical Support Services Department. On occasion the employee may be required to also travel to the district facilities (Ras Tanura, Al-Hasa, Abqaiq and Udhailiyah), remote clinics (Haradh, Tanajib, Shaybah and Khurais) and JHAH designated facilities. The employee will work as a Consultant Medical Physicist during regular working hours and may on occasion provide after hour coverage as well. Hence, the work hours will be mandated to meet the operational needs as directed by Radiology management.

Principal Contacts

The employee’s primary contacts will be with all staff within Radiology Imaging Services and Radiology Imaging Division, in addition to other JHAH medical staff that is responsible for safe use of x-ray emitting devices. Per operational demand the employee may also be required to interact with IT, clinical engineering unit, Gulf Medical/Agfa onsite service engineers, Radiology PACS administrators, imaging equipment vendor service engineers, medical and facility services staff and/or other services’ key personnel. On occasion, the need may also arise to communicate with JHAH medical designated facility personnel, tele-radiology vendor contact personnel and the public.

Principal Duties

  1. Development of purchasing and acceptance specifications documentation for imaging equipment procurement.
  2. Evaluate vendor RFQ responses, perform comparative analysis and provide technical recommendation to Radiology Imaging department equipment purchasing committee.
  3. Perform acceptance testing, calibration and annual safety surveys of imaging equipment (e.g.: CT, ultrasound, mammography, fixed and portable general radiography, fixed and portable fluoroscopy, angiography suites, lithotripsy, dentistry and cath. lab suites), most of which use flat panel receptor technology.
  4. Perform acceptance testing and calibration of auxiliary devices (e.g.: workstation display monitors, CR digitizers, etc.).
  5. Develop, implement and supervise modality quality control programs.
  6. Develop, implement and supervise modality accreditation programs.
  7. Participate in modality imaging chain troubleshooting (working with vendor service engineers and onsite clinical engineers).
  8. Perform image/dose optimization studies.
  9. Provide consultation with radiologist concerning patient and fetal dose determinations.
  10. Consult with other physicians and patients regarding radiation exposure and safety.
  11. Develop and maintain modality patient dose management system.
  12. Provide mammography consultative services to JHAH designated facility clinical sites.
  13. Participate in Radiology Imaging Department financial and staff planning; and equipment utilization studies.
  14. Teaching and presentation of continuing education programs for radiology residents and technologists, graduate students, physicians, nurses, ancillary personnel and other staff.
  15. Participate in planning for future radiology facilities.
  16. Assist in the Radiology safety program.
  17. Perform clinical trials of new imaging devices and/or modalities for improving diagnostic uses of radiation.
  18. Participate in the Saudi Board of Radiology resident medical physics course (coordinated by Saudi Medical Physics Society).
  19. Participate in clinical and basic research.
