Study Notes
Terminology, Modeling, and Measurement in Medical Physics
- Terminology is the science of terms.
- Physics is the science of nature.
- Medical physics is a term of science that overlaps two fields: medicine and physics.
- Medical physics concerns the study of several fields of physics in the body, including:
- Physical parameters that involve in the function of the body and affect the body (e.g., pressure, force, energy, power, and electricity).
- Physics of body organs and systems (e.g., vision, hearing, skeletal, pulmonary, cardiovascular, and nervous systems).
- Applications of physics in the practice of medicine (e.g., laser, sound and ultrasound, X-rays, CT scans, MRI, ECG, EEG, ERG).
Standard and Nonstandard Units in Medicine
- Standard units: some quantities in medicine are measured in the same units for measurement (e.g., force in newton, work in joule, power in watts).
- Nonstandard units: some quantities in medicine are measured in special units that are different from the units used outside of medicine (e.g., pressure in mmHg or cmHg instead of N/m² or dyne/cm², energy in kilocalorie or calorie instead of joule).
Repetitive and Nonrepetitive Measurements
- Repetitive measurements: include quantities that are measured in repetition per unit time (e.g., pulse rate, breathing rate, electrical signals from the brain).
- Nonrepetitive measurements: include quantities that are not repetitive or uniform (e.g., time of kidney function, food digestion, nerve signals, eye movement).
Accuracy of Measurement
- Medical measurements should be very accurate, with a low percentage of error to avoid risky results.
- Errors can occur due to measuring instruments, psychological reasons, and other factors.
- Inaccurate measurements can lead to false negative or false positive errors.
Reducing Diagnostic Errors and Measurement Uncertainties
- Ways to reduce errors and uncertainties:
- Research into causes of misleading laboratory test values.
- Repeating measurements.
- Care in taking measurements.
- Developing new clinical tests.
- Improving instrumentation.
- Using reliable instruments.
- Calibration of instruments to standard or already calibrated instruments.
Medical Measurements and Treatment
- Medical measurements that precede treatment:
- Routine measurements (e.g., body temperature, pulse rate, blood pressure, body weight).
- Other required tests according to the patient's case (e.g., laboratory investigation, body signals investigation, machinery measuring instruments).
Applications of Physics in Medicine
- Sound in medicine:
- General properties of sound.
- The stethoscope.
- Ultrasound picture of the body.
- Ultrasound to measure motion.
- Physiological effects of ultrasound in therapy.
- Light in medicine:
- Measurement of light and its units.
- Applications of visible light in medicine.
- Applications of microscopes in medicine.
- Physics of the eyes and vision:
- Defective vision and its correction.
- Instruments used in ophthalmology.
- Laser in medicine:
- Generation of laser light.
- Applications to medicine.
- Physics of diagnostic X-rays:
- Production of X-ray beams.
- How X-ray is absorbed.
- Fluoroscopy.
- CT scan.
- Physics of nuclear medicine:
- Units of radioactivity.
- Basic instrumentation of nuclear medicine.
- Radiation doses in nuclear medicine.
- Physics of radiation therapy:
- Dose units in radiotherapy.
- Principles of radiation therapy.
- Radiation detection:
- Biological effects of ionizing radiation.
- Radiation protection in radiation therapy.
- Magnetic resonance imaging (MRI).
