In photoacoustic tomography (PAT) with flat sensor, we routinely encounter two types of limited data.

We derive a one-to-one map between wavefront directions in image and data spaces in PAT which suggests near equivalence between the recovery of the initial pressure and PAT data from compressed/subsampled measurements when assuming sparsity in Curvelet frame.
