arim.models.block_in_contact

Model for solid block on which the probe is in direct contact

Imaging should work as expected.

The forward model is not finalised and is not experimentally validated. Buyer beware.

Known issue :

• the model is not reciprocal (swapping the transmitter and the receiver gives different results)

Limits of the forward model:

• the scaling between the L and the T directivity of the elements is dubious

• material underneath is fluid

• do not model reflection against the backwall
