Abstract

Various methods and apparatus are described for reducing signal artifacts resulting from reflections from the surface of the object. In one method, a similar paths algorithm is used to create a calibration signal to reduce signal artefacts. In another method, an equivalent location algorithm is used to create calibration data to reduce signal artefacts, in another method, blocking screens are positioned in contact with, or closely adjacent to, the surface. In another method, an anti-reflective layer is employed. The methods may be employed singly or jointly in a breast tumour imaging device.
