) → Array#

Compute transmit arrival times for plane wave imaging.

Parameters:

  • directions – List of wave direction vectors

  • scan_coords_m – Output positions for beamforming (N, 3) in meters

  • speed_of_sound – Speed of sound in the medium

  • origin – Wave origin point, defaults to [0, 0, 0] Can also be parsed from ultrasound_angles_to_cartesian(channel_data.sequence[idx].origin)

  • xp – Array namespace (optional, will be inferred from scan_coords_m)

Returns:

Array of transmit arrival times with shape (n_transmits, n_points)
