Geometry of an ultrasonic element.
Parameters
| Parameter | Datatype | Description |
|---|---|---|
| perimeter | Array of vector3d | Define the element perimeter. The last element of perimeter is automatically connected to the first. |
Notes
Perimeter
The perimeter is a list of 3D-coordinates expressed in its own cartesian coordinate system. It is assumed that the acoustic center of the element is at origin $O = (0, 0, 0)$. If an element of the probe does not face $Z = (0, 0, 1)$, it should be rotated using the element.transform attribute.
The following example represents an element.perimeter:
element : {
perimeter : [
[3, -2, 0],
[-3, -2, 0],
[-2, 3, 0],
[2, 3, 0]
]
}
