A computer system (MD) and relates method for spectral-data based material decomposition. The system comprises a statistical module (SM) configured to fit, per patch in input spectral imagery, a set of probability distributions (Pk) to a respective vector spectral diagram () for the respective patch (A). The patch is one of a plurality of patches in the input spectral imagery obtained by operation of a spectral imaging apparatus. The probability distributions are combinable into a probability map indicative of material type probabilities per image location in the input spectral imagery.

Multi-material decomposition for spectral computed tomography

A method for inserting an invasive tool, including: attaching a frame to a human body adjacent to a portion of the body; acquiring an image of the body; determining a trajectory of the tool on the image; calculating points of intersection between the trajectory and two sheet which are adapted to be inserted into the frame; perforating the sheets at the calculated points; placing the sheet within the frame; and inserting the invasive tool through the perforations.
