Prostate phantom comprising an artificial prostate () and an artificial lesion arranged within the artificial prostate (), wherein the artificial prostate () comprises: a first part () mimicking a peripheral zone of a zonal anatomy of the prostate, the first part () being made of a first artificial tissue and comprising a closed outer surface, at least a second part () separate from the first part () and mimicking at least a second zone of the zonal anatomy of the prostate, the second part () being made of a second artificial tissue and comprising a closed outer surface, the first () and second () parts contacting each other along an interface mimicking a boundary between the peripheral zone and the second zone.

Prostate phantom, system for planning a focal therapy of a prostate cancer comprising such prostate phantom and method for planning a focal therapy of a prostate cancer implementing such system

Calibration phantom and method for measuring and correcting geometric distortions in an image of a body part of a patient Calibration phantom () for a medical imaging system, comprising a plurality of separate detection elements () arranged in a determined pattern, each detection element () containing a product that is visible by the medical imaging system.
