Medical Physics

The Department of Radiology's Medical Physics division:

  • Provides technical support for the Division of Radiation Oncology in treating over 800 patients annually by ensuring that each treatment is safely and accurately administered. We also provide support for other divisions of the Department of Radiology – performing more than 60,000 procedures each year
  • Provides quality assurance services for the radiation oncology division and monitors radiation safety for all Scott & White facilities
  • Conducts research for the radiology department. Research efforts focus on improving patient care and advancing radiation technology
  • Provides education and training to dosimetrists, residents, medical students and fellowsmore

Diagnostic Radiology Support

The physicists at Scott & White supporting Diagnostic Radiology are intimately familiar with the:

  • Principles of imaging physics and of radiation protection
  • Current guidelines of the National Council on Radiation Protection and Measurements (NCRP)
  • Laws pertaining to the performance of the equipment being tested
  • Function, clinical uses and performance specifications of the imaging equipment
  • Calibration processes and limitations of the instruments used for testing performance

The medical physicists perform initial and annual surveys of diagnostic imaging equipment and review, interpret and approve all data measurement.

The diagnostic radiology physicists at Scott & White are certified in diagnostic physics by the American Board of Radiology and hold licenses from the Texas Board of Licensure for Professional Medical Physicists renewed annually having satisfied the Board's criteria for Continuing Medical Education.

Therapeutic Radiology Support

Support for Radiation Oncology

Responsibilities of a radiation oncology physicist:

  • Calibration of the therapy equipment
  • Determine radiation dose distributions in patients undergoing treatment (i.e., computerized dosimetry planning or direct radiation measurement)
  • Weekly review of the dose delivered to the patient
  • Certify that the treatment machines perform according to specifications after installation
  • Generate the data necessary for accurate treatment planning and delivery of the radiation therapy
  • Outline written QA procedures that include tests to be performed, tolerances and frequency of the tests
  • Understand and appropriately respond to machine malfunctions and related safety issues

Working with technology and other physicians to develop customized treatment plans

Scott & White's physicists and dosimetrists consult with the radiation oncologists and other team members to ensure that the optimum treatment plan is developed for each patient.

Using computerized treatment planning systems to calculate, analyze, and optimize the treatment parameters, medical dosimetrists and medical physicists at Scott & White ensure that the treatment plan for every individual patient complies with the physician's dose prescription.

Certified and licensed medical physicists

The radiation oncology physicists at Scott & White are certified in radiation oncology physics by the American Board of Radiology and hold licenses from the Texas Board of Licensure for Professional Medical Physicists renewed annually after having satisfied the Board's criteria for Continuing Medical Education.
