The Viamo c100 TUS-VC100 Diagnostic Ultrasound System is an integrated, preprogrammed, color Doppler ultrasound imaging system, capable of producing high detail resolution intended for clinical diagnostic imaging applications. This system is a Track 3 device that employs a wide array of probes that include linear array, convex array and phased array. This system consists of a mobile console with keyboard control panel, power supply module, color LCD monitor and optional probes. This system utilizes the ultrasound echo characteristics, transmits ultrasonic energy into patient body, sweeps in a certain direction, processes the signals according to the delay time and the echo strength, and images the organs by using the electronic circuits and backend controller to process, then analyzes the distance and the status of organs; and at the same time, this system utilizes Doppler and autocorrelation technology to image the blood flow and add the color-coding information to the grayscale image of B mode, then displays the image in real time. The probes provided with this system are electrical-acoustical-electrical transducers. The probes firstly convert the electric excitation signal to the acoustic signal and transmit the signal into the patient body, then converts the echo signals from the patient body to electric signal. The echo signal is processed and converted by DSC to image signal to output to the LCD display. This system is a mobile, general purpose, software controlled, color diagnostic ultrasound system. Its basic function is to acquire ultrasound echo data and to display the image B-Mode (including Tissue Harmonic Imaging), M-Mode, Pulsed (PW) Doppler Mode, Continuous (CW) Doppler Mode, Color Doppler Mode, Power Doppler Mode, Directional Power Doppler Mode, TDI Mode or a combination of these modes and 3D/4D.
