Our Medical Physics Expertise
Our radiologic physics group
Our Department of Radiation Oncology boasts one of the strongest physics departments of any cancer center in the U.S., with nine full-time medical physicists on staff. This allows us to take full advantage of powerful new technologies to provide the most advanced treatment options for our patients.
Safely increasing the dose of radiation, while limiting the exposure to healthy
tissue, is the key to better control of tumors with the fewest possible side
effects. Our physicists work side-by-side with physicians in each patient's
Physicists meet weekly with clinical faculty to share ideas about how emerging
technologies can be used to deliver better care to patients. In addition, they
hold biweekly research conferences to share innovations and foster collaboration.
Bringing Research Discoveries to Patients
UMGCC's strong commitment to translating research into new treatments has yielded
some important innovations. UMGCC researchers developed Direct Aperture Optimization
(DAO), a treatment planning tool to enhance IMRT
treatment plans. Other research initiatives currently underway include 4D CT
imaging for treatment planning, synchronizing treatment with the respiratory
cycle, and intensity-modulated arc therapy (IMAT) planning.
This emphasis on translational research in radiation therapy has led to UMGCC
being among a select group of only four centers in the country to have a Master
Research Agreement with Varian Medical Systems, the market leader in the development
of radiation therapy technology.
Calculating the dose of each radiation treatment is the job of the medical
dosimetrist. These specially-trained professionals are involved in treatment
planning, dose measurement, dose calculations and quality assurance for radiotherapy
treatments designed to treat cancer. The medical dosimetrist is an integral
member of the treatment team, which includes radiation oncologists, medical
physicists, radiation therapists and nurses.
Under the direction of the medical physicist and/or radiation oncologist, the dosimetrist determines the beam arrangements, beam shapes, beam weights and beam energies that provide the highest quality treatment plan. The dosimetrist is also responsible for maintaining continuing quality assurance and for the construction of special treatment devices.
The University of Maryland School of Medicine’s dosimetrist
training program is one of only eight programs in the U.S. accredited by
the Medical Dosimetry Certification Board. Our one-year program combines extensive
curriculum with hands-on training to prepare our students for a career in medical
