The aim of this work is to investigate the possible synergy between k-space inverse-Hanning filtering and coRASOR for background suppressed positive contrast device visualisation. For visualisation of brachytherapy seeds in ex vivo tissue, Inverse-Hanning filtering of k-space was demonstrated to be effective in suppressing background signal, clearly increasing CNR, however, at the cost of blurring in image space.
