  Here we present a novel microlocal analysis of a new toric section transform
which describes a two dimensional image reconstruction problem in Compton
scattering tomography and airport baggage screening. By an analysis of two
separate limited data problems for the circle transform and using microlocal
analysis, we show that the canonical relation of the toric section transform is
2--1. This implies that there are image artefacts in the filtered
backprojection reconstruction. We provide explicit expressions for the expected
artefacts and demonstrate these by simulations. In addition, we prove
injectivity of the forward operator for $L^\infty$ functions supported inside
the open unit ball. We present reconstructions from simulated data using a
discrete approach and several regularizers with varying levels of added
pseudo-random noise.
