The scan converter in sonography is used to convert the analog signals and to display the data on a visual screen. The converter coordinates the components of the scanner, stores the data in memory and displays the retrieved digital information on a display screen.
Function
The scan converter in sonography will have a computer chip that receives the analog signals from the radial scan lines. Such data will be illustrated with the echo signals received from the analogue device and then, based on the speed and angle of deflection, the calculations are carried out. The scan converter has a random access memory that stores the digital signals that are converted by the scan converter.
Advantages
The main advantage of the scan converter in sonography is that it helps to convert the analogue signals to digital signals easily and accurately. These digital signals can be used for further processes and references.
Application
The scan converter in sonography processes ultrasonic signals that echo when it hits an object. This is done by the use of certain algorithms that produce an ultrasonic image, which is required to be displayed on the screen. Hence, sonography is very helpful in calculating the accurate depth of the sea, for example. Usually the crew in ships use this device to measure the depth of the sea to make their journey safe. Ultrasound also is used in the medical field for visualizing internal body structures.
