Top 10 Questions for Medical Physics Teacher Interview

1. Describe the fundamental principles of radiation physics as they apply to medical imaging.

In medical imaging, radiation physics plays a crucial role in creating images of the human body for diagnostic purposes. It involves the interaction of radiation with biological tissues, and understanding these interactions is essential for optimizing image quality and minimizing patient exposure.

• X-ray production: X-rays are produced when high-energy electrons interact with a target material, such as tungsten or molybdenum. The energy of the X-rays depends on the accelerating voltage applied to the electrons.
• X-ray attenuation: As X-rays pass through tissues, they are attenuated or absorbed to varying degrees depending on the density and atomic number of the tissues. Denser tissues, such as bone, attenuate X-rays more than less dense tissues, such as soft tissue.
• Image formation: The attenuated X-rays are detected by a detector, such as an image intensifier or a digital detector. The resulting electrical signals are processed to create an image that represents the distribution of X-ray attenuation in the body.

2. Explain the concept of radiation dosimetry and its importance in medical imaging.

Radiation dosimetry is the measurement and calculation of the amount of radiation absorbed by a patient during an imaging procedure. It is important to ensure that patients are exposed to the lowest possible radiation dose while still obtaining diagnostic-quality images.

Factors affecting radiation dose

• kVp (peak kilovoltage): Higher kVp results in higher X-ray energy and less patient dose.
• mA (milliamperes): Higher mA results in more X-rays being produced and higher patient dose.
• Exposure time: Longer exposure time results in higher patient dose.
• Collimation: Using collimators to narrow the X-ray beam reduces patient dose.
• Patient size and composition: Larger patients and patients with denser tissues absorb more radiation.

Methods of radiation dosimetry

• Ionization chambers: Measure the amount of ionization produced by radiation in a gas-filled chamber.
• Thermoluminescent dosimeters (TLDs): Measure the amount of light emitted by a material after it has been exposed to radiation.
• Film badges: Measure the amount of radiation exposure by darkening of a photographic film.

3. Describe the different types of medical imaging modalities and their applications.

• X-ray radiography: Produces 2D images of the body using X-rays.
• Computed tomography (CT): Produces cross-sectional images of the body using X-rays and computer processing.
• Magnetic resonance imaging (MRI): Produces images of the body using magnetic fields and radio waves.
• Ultrasound: Produces images of the body using high-frequency sound waves.
• Nuclear medicine: Uses radioactive tracers to image the body and assess its function.

4. Explain the role of quality assurance (QA) in medical imaging and describe some common QA tests.

QA is essential in medical imaging to ensure that equipment is functioning properly and that images are of high quality and diagnostic value.

• Equipment calibration: Regularly calibrating imaging equipment ensures that it is operating within specified parameters.
• Image quality control: Regularly performing image quality control tests, such as phantom imaging, helps to identify and correct any problems with image quality.
• Radiation safety: Implementing radiation safety protocols helps to protect patients and staff from unnecessary radiation exposure.

5. Discuss the ethical considerations in medical imaging, including patient privacy and informed consent.

Medical imaging involves the use of potentially harmful radiation, and it is important to ensure that patients are fully informed about the risks and benefits of the procedure and that they provide informed consent before undergoing the imaging exam.

• Patient privacy: Medical images and patient information must be kept confidential and secure.
• Informed consent: Patients must be provided with clear and concise information about the imaging procedure, including the risks and benefits, before they consent to the exam.
• Radiation safety: Patients should be exposed to the lowest possible radiation dose while still obtaining diagnostic-quality images.

6. Describe the different career paths available to medical physics teachers.

• Academia: Teaching and research in medical physics at universities and colleges.
• Clinical physics: Working in hospitals and clinics to ensure the safe and effective use of radiation in medical imaging and therapy.
