Ultrasonic element, also called transducer.

UAC	URX	Parameter	Datatype	Description
✓	✓	element_geometry	Reference to element_geometry	Reference to an element_geometry in probe. When multiples urx.elements of a probe have the same geometry, they can all share the same element of the array probe.element_geometries. Stored as a weak pointer from field element_geometries of its parent probe.
✓	✓	impulse_response	Reference to impulse_response	Reference to an impulse_response in probe. When multiples urx.elements of a probe have the same impulse response, they can all share the same element of the array probe.impulse_responses. Stored as a weak pointer from field impulse_responses of its parent probe.
✓	✓	transform	transform	Attitude of the element in space. The transform is applied in the probe reference space. Stored as a raw objet.
