Exam B-RX

Temporal Shaping
The exam software can send up to two temporal pulse shapes (A & B) for each scan line. (The software can send many more pulses of the same temporal shape but with different focal distance, for the same scan line. see ...) The pattern of the pulse is loaded from a file called pulses.txt which can be found in \Ultrasonix\Exam\config folder. The indices of the chosen patterns from this file for the two pulses A and B are set by these parameters:
 * Pulse Index A
 * Pulse Index B

Receive Beam Forming
The aperture opening for different depths is determined through Rx Aperture. It represents the receive aperture as a function of elements vs depth (see System Curves): Maximum number of elements that can be in the receive aperture. Value represents half the aperture, as all calculations are symmetrical: Depth at which the Rx Aperture Curve is valid for. All depths beyond this value will use the last calculated value of the curve at this depth:
 * Rx Aperture
 * Rx Aperture Max
 * Rx Curve Depth

If The sequence involves multiple acquisitions of each scan line through the Accumulator parameter, the aperture opening can be programmed to be different for subsequent scan lines:
 * Use Rx Aperture (Accum)
 * Rx Aperture (Accum)
 * Rx Aperture Max (Accum)
 * Rx Curve Depth (Accum)
