Experimental investigation of focal point positioning: a–c 5 mm inside the medullar cavity; d–f in the plane of the cortical breakthrough; g–i 5 mm in front of the medullar cavity for a given sample. The columns show (left to right, respectively): the position of the focus, the axial temperature elevation map after 400 s of sonication, the cross correlation between the PRFS thermometry in soft tissue adjacent to the bone and the fluoroptical measurements inside the cortical bone
