A Mode Ultrasound
Der a mode ist die urform der sonographischen diagnostik.
A mode ultrasound. The echo information derives from tissue interfaces along a single line in the direction of the sound beam. Ultrasound or sonography in medicine technique that uses sound waves to study and treat hard to reach body areas. The different types of modes can be controlled by the operator or tech. And if some of the scatterers are moving the motion curve can be traced by letting the b mode image sweep across a screen or paper as illustrated in fig.
A mode is an operational state that a system has been switched to. A normal mode occurs when all parts of a system oscillate with the same frequency. In scanning with ultrasound high frequency sound waves are transmitted to the area of interest and the returning echoes recorded for more detail see ultrasonics ultrasonics study and application of the energy of sound waves vibrating at frequencies greater than 20 000 cycles. The mode is used in echoencephalography.
Medical ultrasound also known as diagnostic sonography or ultrasonography is a diagnostic imaging technique or therapeutic application of ultrasound it is used to create an image of internal body structures such as tendons muscles joints blood vessels and internal organs its aim is often to find a source of a disease or to exclude pathology the practice of examining pregnant women using.
