This system is not limited by prostate/patient motion and allows for a deformation of the organ during registration.

Paradigm shift images registration#

Organ-based registration (Koelis) does not aim to track the TRUS probe, but the prostate itself to compute in a 3D acquisition the TRUS prostate shape, allowing for a registration with the corresponding 3D MRI shape. Two systems (Artemis and Uronav) have been developed to partially circumvent this drawback. Its main limitation is that it does not take into account prostate and patient motion during biopsy. Sensor-based registration consists of tracking in real time the TRUS probe with a magnetic device, achieving a global positioning system which overlays in real-time prostate image on both modalities. Cognitive registration consists of aiming a suspicious area during biopsy with the knowledge of the lesion location identified on multiparametric MRI. This property can be used to perform a TRUS–MR image registration, new technological advance, which allows for an overlay of an MRI onto a TRUS image to target a prostate biopsy toward a suspicious area Three types of registration have been developed: cognitive-based, sensor-based, and organ-based registration.

Accuracy of multiparametric MRI has greatly improved the ability of localizing tumor foci of prostate cancer.
