Construction of a medical acoustic microscopy system is discussed with a focus on the usage of a PC-based high-performance GaGe RazorMax digitizer. Three main aspects of RazorMax’s operation are addressed: usage of Dynamic Range Expansion (DRE) to maximize the detectability of small ultrasonic echoes, high-speed PCI Express Data Streaming for the fastest scanning speed, and usage of GaGe’s Trigger Out signal for efficient and synchronous ultrasonic triggering.
