Anatomy mannequins, models and medical simulation systems may facilitate training by rendering a realistic tactile feedback when the end user manipulates the anatomy model with a handheld tool. An anatomy model may comprise various inexpensive material arrangements to replicate the side-to-side motion friction and resistance against the insertion and manipulation of a surgical instrument in a living body soft body tissue, such as muscle or ligament layers, while ensuring sustainability of the corresponding simulator parts over at least thousands of training sessions. A mesh layer may be arranged as an interlinked mesh of elastomer strands. A soft body layer may also be arranged as a grid of flexible protruding elements. The instrument may be inserted and manipulated through the crossings of the interlinked elastomer strands and/or the recesses or channels between the flexible protruding elements to provide a tactile feedback similar to that of real surgery tool handheld manipulation.

An ultrasound simulation method for rendering an ultrasound image of an anatomy model, comprises acquiring, with at least one model sensor, a position and/or orientation of the model; acquiring, with at least one probe replicate sensor, a position and/or orientation of an ultrasound imaging probe replicate, the ultrasound imaging probe replicate interacting with low friction with at least one anatomy model surface, the model surface being deformed by the pressure of the ultrasound imaging probe replicate; aligning a VR/AR model to the tracked position and orientation of the anatomy model and the ultrasound imaging probe replicate; interpolating a 2D ultrasound slice by sampling through a standard reconstructed 3D ultrasound volume, as a function of the tracked position and orientation of the anatomy model and the ultrasound imaging probe replicate.
