Medical Physicists

UW Health medical physicists work directly with radiation oncologists during treatment planning and delivery at the University of Wisconsin Carbone Comprehensive Cancer Center.


They oversee the work of the dosimetrists and help ensure that treatments are tailored to each patient. Medical physicists are responsible for developing and directing quality control programs for equipment and procedures.


Our experienced team of experts is involved in the treatment of every patient, and incorporates recommendations and guidelines from the American Association of Medical Physicists (AAPM), American College of Radiology (ACR) and the American Society of Therapeutic Radiation Oncology (ASTRO) in addition to federal and state guidelines.


The medical physics group determines the need for and establishes specifications for dosimetric and treatment planning equipment, including:

  • Measurement instruments to calibrate all treatment equipment and patient monitoring devices, including ionization chambers/electrometers used as local standards and field instruments, readout devices, constancy check instruments and phantoms
  • Computerized treatment planning systems
  • Computerized water phantom systems with appropriate ionization chambers or diodes
  • Film density systems
  • Patient dose monitoring systems, such as diodes and thermoluminescence dosimeters (TLDs)
  • Radiation protection measurement devices
  • Quality assurance test tools for radiation therapy equipment
