6 Redrivers in Medical

The backend ports of medical equipment’s backends have USB ports for data-transfer. In equipment such as ultrasound and X-ray depending upon the resolution of the live images being transferred & depending on the screen size being transferred to, lower speed USB can be used for smaller screen. For premium ultrasound usually Type-C and USB3.1 (higher data-rates) are used.

Figure 6-1 shows a Standard ultrasound which has Type-C for data-transfer. Since the Type-C port is external, any cable length can be interfaced with the Type-C port causing the need of re-driver between the processor and the Type-C port to preserve signal-integrity.

Figure 6-2 shows an X-ray machine which has Type-C for data-transfer. Since the type-C port is external, any cable length can be interfaced with the Type-C port causing the need of re-driver between the processor and the Type-C port to preserve signal-integrity.
