 Definition of Medical physics  التعريف منقول عن موسوعة ويكيبدياMedical physics is the application of physics to medicine. It generally concerns physics as applied to medical imaging and radiotherapy, although a medical physicist may also work in many other areas of healthcare. A medical physics department may be based in either a hospital or a university and its work is likely to include research, technical development, and clinical healthcare. Areas of specialtyOf the large body of medical physicists in academia and clinics, roughly 85% practice or specialize in various forms of therapy, 10% in diagnostic imaging, and 5% in nuclear medicine Areas of specialty in medical physics however are widely varied in scope and breadth. Medical imaging Para-sagittal MRI of the head in a patient with benign familial macrocephaly. Treatment of diseaseDiagnostic radiology, including x-rays, fluoroscopy, mammography, Dual energy X-ray absorptiometry, angiography and Computed tomography Ultrasound, including intravascular ultrasound (Non-ionising radiationLasers, Ultraviolet etc.) Nuclear medicine, including SPECT and positron emission tomography (PET) Magnetic resonance imaging (MRI), including functional magnetic resonance imaging (fMRI) and other methods for functional neuroimaging of the brain. For example, nuclear magnetic resonance (often referred to as magnetic resonance imaging to avoid the common concerns about radiation), uses the phenomenon of nuclear resonance to image the human body. Magnetoencephalography Electrical impedance tomography Diffuse optical imaging Optical coherence tomography High intensity focussed and Lasik Nuclear medicine, including unsealed source radiotherapy Physiological measurement techniquesPhotomedicine, the use of light to treat and diagnose disease Radiotherapy TomoTherapy Cyberknife Gamma knife Proton therapy Brachytherapy Boron Neutron Capture Therapy Sealed source radiotherapy Terahertz radiation ECG trace Radiation protectionUsed to monitor and measure various physiological parameters. Many physiological measurement techniques are non-invasive and can be used in conjunction with, or as an alternative to, other invasive methods. Electrocardiography Electromyography Electroencephalography Electronystagmography Endoscopy Medical ultrasonography (Non-ionising radiationLasers, Ultraviolet etc.) Near infrared spectroscopy Pulse oximetry Blood gas monitor Blood pressure measurement Background radiation Medical computing and mathematicsRadiation protection Dosimetry Health Physics Radiological Protection of Patients CT image reconstruction Education and trainingMedical informatics Telemedicine Picture archiving and communication systemsPACS) ( DICOM Tomographic reconstruction, an ill-posedinverse problem [Advanced Digital Imaging Solutions LaboratoryADISL] The primary clinical responsibility of the Qualified Medical Physicist is to "assure the safe and effective delivery of radiation to achieve a diagnostic or therapeutic result as prescribed in patient care (Medical Physics Scope of Practice)". Various training programs exist to accommodate the demand for specialization in this field. Legislative and advisory bodies |
