Towards Real‐time Free‐hand Biopsy Navigation by Beitone, Clément; Fiard, Gaëlle; Troccaz, Jocelyne is a Medicine article available to read on EtoBox.

## Purpose: Performing a transrectal ultrasound (trus) prostate biopsy is at the heart of the current prostate cancer detection procedure. with today's two-dimensional (2d) live ultrasound (us) imaging equipment, this task remains complex due to the poor visibility of cancerous tissue on trus images and the limited anatomical context available in the 2d trus plane. this paper presents a rigid 2d/3dus registration method for navigated prostate biopsy. this allows continuous localization of the biopsy trajectory during the procedure. ## Methods: We proposed an organ-based approach to achieve real-time rigid registration without the need for any probe localization device. the registration method combines image similarity and geometric proximity of detected features. additions to our previous work include a multi-level approach and the use of a rejection rate favouring the best matches. their aim is to increase the accuracy and time performances. these modifications and their in-depth evaluation on real clinical cases and comparison to this previous work are described. we performed static and dynamic evaluations along biopsy trajectories on a very large amount of data acquired under un
