I have chosen Ultra Sound Medical Imaging, because of personal interest and experience. This technology is very impotent in detecting healthy or unhealthy births, cancer or tumors without going through painful surgery.
Ultra sound can detect breast cancer missed by mammograms.
Ultra Sound works similar to the Sonar systems they have on ships. Sonar has been used as far back as World War 2, for military work to detect enemy submarines. Sonar sends out short pulses of sound, which travels through the water to detect an object. The detector receives this information and it is sent back to the boat. Ultra Sound uses high-frequency sound waves to produce images.
