NEW YORK, Nov. 8, 2016 /PRNewswire/ -- The global ultrasound market is projected to reach USD 6.92 million by the end of 2021, growing with a CAGR of 5.5% from 2016 to 2021. Ultrasound is a sound with frequencies higher than about 20 kHz. It moves in a wavelike manner through which it travels. The waves travel with different speed in different medium. The medical ultrasound system operates at higher frequencies, typically 1-10 MHz.Ultrasound imaging is a medical imaging technique which uses high frequency sound waves and their echoes. It exposes body parts to high frequency sound waves in order to create images of the internal organs of the body. It does not use ionizing radiation. It provides a real time structure and movement of body's internal organs and blood flowing through blood vessels. It helps in evaluation of symptoms such as swelling, pain, infection and hematuria. In addition, it is also used for guide procedures such as needle biopsies, guide biopsy of breast and diagnosis of various heart conditions. However, it cannot penetrate mature bones and substantial gas layers. Segments Covered:The report segments the global ultrasound market by technology, device display, device portability, application and region. The technologies include diagnostic ultrasound and therapeutic ultrasound. Device displays include color devices, and black & white devices. The market by device portability is segmented into trolley/cart based devices and compact/handheld devices whereas the market by application is segmented into radiology/general imaging applications, obstetrics/gynaecological applications, cardiological applications, urological applications, vascular applications, and other applications.
