Description

Modern medicine is a large consumer of physics technologies. The series of lectures covers medical imaging starting with an overview and the history of medical imaging. Then follows four lectures covering

x-ray imaging
positron emission tomography
imaging blood flow by ultrasound
magnetic resonance

Ultrasound Imaging blood flow with ultrasound Diagnostic ultrasound relies on the reflection of short pulses of ultrasound (2 - 14 MHz) from structures within the body to construct images of an organ, or to measure/image velocities of moving structures such as blood. The most common modalities are pulse-echo B-scanning, spectral Doppler and color flow imaging. Many recent innovations including tissue harmonic imaging, contrast agents, 3-D imaging and tissue Doppler have extended the scope of ultrasound. It is estimated that there are more installed ultrasound machines than all other diagnostic techniques combined. Arteriosclerotic narrowing of the arterial lumen and the resulting blood flow reduction are responsible for stroke, peripheral arterial disease and cardiovascular morbidity and mortality. Thrombus formation in the venous system leads to pulmonary embolism and chronic venous insufficiency. Thus, the application of ultrasound in the diagnosis of vascular disease is an exciting medical innovation.
