Two principles of operations: - Principle 1 of operations - Principle 2 of operations Principle 1 of operations: -The ultrasound machine operates and presents the information on the monitor. -There is a one-to-one correspondence between transmitting a pulse into the body and the echoes returning from that pulse and presenting it as a visible dot developing a scan line (one pulse at a time). Principle 1 of Operation: Repeating this ___________ times, would produce a single image...
