uff.aperture < uff
UFF class to define analytically the aperture use in an ultrasound wave
Parameters
| Parameter | Datatype | Description |
|---|---|---|
| origin | uff.position | Location of the aperture center in space |
| window | string | String defining the apodization window type and parameter (e.g., 'Hamming', 'Gauss(8)', 'Tukey(0.5)') |
| f_number | double or single | Desired F-number of the aperture [Az, El] |
| fixed_size | double or single | If non-zero, this overwrites the size of the aperture in m [Az, El] |
| minimun_size | double or single | (Optional) If non-zero, this sets a limit for the minimum dynamic aperture in m [Az, El] |
| maximum_size | double or single | (Optional) If non-zero, this sets a limit for the maximum dynamic aperture in m [Az, El] |
Notes
The class aperture defines the transmit apodization profile. In this case origin defines the center of the aperture. The size of the aperture can be described with fixed_size, or with f_number in which case the aperture size is d/f_number where d is the distance between uff.wave.origin and uff.wave.aperture.origin. The parameter window is a string describing the apodization window.
