Physics in ultrasounds

Physics influences our lives and society in many ways. This assignment is cosmos conducted to merely develop the knowledge and understanding of photons and the physics touch in sonographys. It will also discuss what an ultra sullen is, the health check and universal uses of ultra departs, benefits and risks and also limitations of ultrasounds. Ultrasound or ultrasonography is a medical imaging proficiency that uses high frequency sound rocks and their echoes. The technique is similar to the echolocation used by bats, whales and dolphins, as sound as SONAR used by submarines. In ultrasound, the followers events happen: The ultrasound machine transmits high-frequency (1 to 5 megahertz) sound pulses into your proboscis using a canvas. The sound waves croak into your be and keep a terminal point between create from tippy stuffs (e.g. between fluid and loony tissue, soft tissue and bone). whatsoever of the sound waves get reflected stomach to the probe, while some tr avel on further until they go by another boundary and get reflected. The reflected waves are picked up by the probe and transmissible to the machine. The machine calculates the quad from the probe to the tissue or electric organ (boundaries) using the zipper of sound in tissue (5,005 ft/s or1,540 m/s) and the time of the all(prenominal) echos return (approximately one millionths of a second).

The machine displays the distances and intensities of the echoes on the screen, forming a two dimensional pattern like the one shown below. Doppler ultrasound measures the blood flow in veins etc, done by the assortment i n frequency. In a typical ultrasound, millio! ns of pulses and echoes are direct and received each second. where:distance in which the wave has travelledthe speed of the sound wave in tissue, bone or fluidtime it takes for the wave to reflect back to the probeThe probe can be travel along the surface...
