We'll also provide insights on finding qualified medical physics professionals and highlight recent trends in the field.

By the end of this article, you'll have a deeper understanding of how medical physics contributes to delivering safe and effective healthcare in Georgia.

Article Outline

Key Medical Physics Services in Georgia

Medical physics encompasses a wide range of services essential for the safe and effective use of radiation in healthcare. In Georgia, these services can be broadly categorized into diagnostic imaging physics and radiation therapy physics.

Diagnostic Imaging Physics

Diagnostic imaging is a critical component of modern medicine, allowing healthcare professionals to visualize the inside of the human body without invasive procedures. Medical physicists play a vital role in ensuring the quality and safety of various imaging modalities, including X-ray, CT, MRI, Ultrasound, and Nuclear Medicine.

For each of these modalities, medical physicists are responsible for:

  1. Quality assurance: Regularly testing and calibrating imaging equipment to ensure optimal performance and image quality.

  2. Equipment optimization: Fine-tuning imaging protocols to balance image quality and radiation dose, minimizing patient exposure while maintaining diagnostic accuracy.

  3. Radiation safety protocols: Developing and implementing safety measures to protect patients and staff from unnecessary radiation exposure during imaging procedures.

According to a published review paper by Virginia Tsapaki entitled “Radiation dose optimization in diagnostic and interventional radiology: Current issues and future perspectives,” Medical physicists' regular quality assurance reduces the average radiation dose per CT scan, highlighting their importance in diagnostic imaging for both patients and establishments.

Radiation Therapy Physics

Radiation therapy is a cornerstone of cancer treatment, using high-energy radiation to destroy cancer cells. Medical physicists are integral to the planning and delivery of radiation therapy, ensuring that treatments are precise, effective, and safe. Their responsibilities include:

  1. External Beam Therapy: Medical physicists work closely with radiation oncologists to develop personalized treatment plans for each patient. They perform complex dose calculations, machine calibrations, and quality checks to ensure the radiation is delivered accurately to the tumor while minimizing exposure to healthy tissues.

  2. Brachytherapy: For cancer treatments involving the implantation of radioactive sources directly into the tumor, medical physicists are responsible for treatment planning, source calibration, and ensuring the safety of both patients and staff.

Meeting Compliance Requirements with Medical Physics

Medical physics services are essential for patient care and for ensuring that healthcare facilities comply with state and federal regulations. In Georgia, medical physicists play a crucial role in meeting the Department of Health and the Nuclear Regulatory Commission (NRC) requirements.

State and Federal Regulations

Medical physicists work diligently to ensure that healthcare facilities adhere to the radiation safety regulations set forth by the Georgia Department of Health and the NRC.

These regulations cover various aspects of radiation use, including:

  1. Occupational dose limits for healthcare workers

  2. Patient exposure limits for diagnostic and therapeutic procedures

  3. Proper handling, storage, and disposal of radioactive materials

  4. Reporting requirements for radiation incidents and overexposures

By staying up-to-date with the latest regulatory changes and incorporating them into daily practice, medical physicists help healthcare facilities maintain compliance and avoid penalties.


In addition to regulatory compliance, medical physicists assist healthcare facilities in attaining and maintaining accreditation from organizations such as the American College of Radiology (ACR). Accreditation demonstrates a facility's commitment to quality and safety and often requires meeting stringent standards for equipment performance, staff qualifications, and patient care.

Medical physicists contribute to the accreditation process by:

  1. Conducting comprehensive equipment evaluations and performance testing

  2. Developing and implementing quality assurance programs

  3. Providing training and education to staff on radiation safety and best practices

Patient and Staff Safety

One of the primary responsibilities of medical physicists is to ensure the safety of patients and staff in radiation environments. They achieve this through dose optimization, facility shielding, and rigorous equipment safety and quality assurance protocols.

Radiation Dose Optimization

Medical physicists work to minimize radiation exposure to patients while maintaining the diagnostic or therapeutic efficacy of the procedure. They achieve this by:

  1. Designing treatment plans that deliver the prescribed radiation dose to the tumor while sparing healthy tissues

  2. Optimizing imaging protocols to balance image quality and radiation dose

  3. Regularly reviewing and updating protocols to incorporate the latest evidence-based practices

Facility Shielding

Medical physicists are also responsible for designing and evaluating the shielding of radiation treatment rooms and imaging suites. Proper shielding is critical for protecting staff and the public from unnecessary radiation exposure. Medical physicists use their expertise in radiation physics to:

  1. Calculate the required thickness and composition of shielding materials

  2. Assess the effectiveness of existing shielding and recommend improvements

  3. Ensure that shielding designs comply with state and federal regulations

Equipment Safety and Quality Assurance

Medical physicists conduct routine testing and maintenance procedures to ensure the safe and effective operation of radiation equipment. These include:

  1. Daily, monthly, and annual quality assurance tests to verify equipment performance

  2. Calibration of radiation output to ensure accurate dose delivery

  3. Troubleshooting and resolving equipment issues

  4. Providing training to staff on the safe operation of radiation equipment

Finding Qualified Medical Physics Services in Georgia

When seeking medical physics services, you must ensure that the professionals you work with are properly qualified and credentialed.


The two primary board certifications for medical physicists in the United States are:

  1. American Board of Radiology (ABR): The ABR offers certification in Diagnostic Medical Physics, Nuclear Medical Physics, and Therapeutic Medical Physics.

  2. American Board of Medical Physics (ABMP): The ABMP offers certification in MRI Physics, Medical Health Physics, and Radiation Oncology Physics.

To verify a physicist's qualifications, search for their name in the ABR or ABMP online directories or request their certification documents.

  1. Proton therapy: In 2018, the first proton therapy center in Georgia opened its doors, offering a highly precise form of radiation therapy for cancer patients. Medical physicists have been instrumental in the planning, commissioning, and operating of this cutting-edge facility.

  2. AI-assisted treatment planning: Several cancer centers in Georgia have begun incorporating artificial intelligence (AI) tools into their radiation treatment planning processes. These tools, developed in collaboration with medical physicists, can help optimize treatment plans and reduce planning time, ultimately improving patient care.

  3. Real-time dosimetry: Medical physicists in Georgia have been working on implementing real-time dosimetry systems that can monitor the radiation dose delivered to patients during procedures. This technology can help ensure that patients receive the prescribed dose while minimizing the risk of overexposure.
