Department of Physics, Unit Catalogue 2011/12
|Level:||Honours (FHEQ level 6)|
|Supplementary Assessment:||Mandatory extra work (where allowed by programme regulations)|
|Requisites:||Before taking this unit you must take PH10007 and take PH10008. Students must have A-level Physics in order to undertake this unit.|
The aim of this unit is to introduce the application of physics and engineering to medicine, for both diagnosis and therapy.
After taking this unit the student should be able to:
* outline the diagnostic and therapeutic uses of x rays, gamma rays, radio frequency radiation, magnetic fields, electrons, neutrons, radionuclides and ultrasonic waves;
* describe the physical principles underlying specific areas of medical imaging and ionising radiation therapy;
* relate the quality of medical images to the physical principles underlying the equipment associated with their production, use, measurement and evaluation;
* perform basic calculations on medical applications of ultrasound, ionising radiations and magnetic resonance imaging;
* describe the principles of measurement of physiological actions, and associated means of signal processing and interpretation;
* develop an awareness of the magnitude of physiological signals obtained from the human body.
