dc.description.abstract	Ultrasound is used in medicine for both diagnostic and therapeutic procedures, but the equipment differs. For diagnosis, ultrasound echography is commonly used to produce cross-sectional images of the body. The Doppler technique is used mainly for blood flow measurement. For therapy, ultrasound is used in ophthalmology for lens treatment, as well as for lithotripsy of kidney stones and gallstones. Modern ultrasound scanners are very reliable. They are also technologically sophisticated; the physician can only maintain the instrument as explained in the section on regular preventive maintenance (page 118). The hospital engineer should be able to rectify about 50% of all the common problems, as these tend to be fairly simple, and involve the transducer (probe) cable or power supply.	en_US
