Exam B-TX

Exam 6.0.3
Changing the preset transmit setting through this parameter will load default values for the other parameters:
 * B-Freq

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 determined by these parameters:
 * Pulse Index A
 * Pulse Index B

The pattern can be repeated a number of times. By default, the pattern is repeated just once. The number of repetitions is determined by:
 * Pulse Repeat

The transmit frequency is set through the parameter:
 * Tx Frequency

The positive and negative amplitudes are determined through:
 * Voltage+
 * Voltage-

The two wires connected to the transducer elements can carry offset voltages, determined by:
 * Voltage Offset+
 * Voltage Offset-

Elements Involved
The aperture opening for different depths is determined through:
 * Tx Aperture (see System Curves)
 * Tx Aperture Max
 * Tx Curve Depth

Time Delays
The transmit focusing can be turned off to achieve a plane wave transmission through:
 * Plane Wave

TODO

 * Power
 * User Frequency
