A signal tracking system including: one fixation element to be secured to a rigid body part of the patient surrounding a target body part, the fixation element further including a mapping element, one tracker element to be secured to the fixation element to track, in real time, the internal tracker, and a control unit including a memory to store an internal referential and one image displaying the target body part and one fixation element. The control unit is designed to define, inside the internal referential, at least one 3D frame position attached to the at least one fixation element, and to precisely locate each point of the target body part, the control unit is further designed to precisely localize, in real time, the internal tracker inside the target body part.

Position tracking system for tracking an internal device during an imaging

A microrobot configured to move in a viscous material, in particular in an organ of a subject such as a brain, the microrobot having a propulsion structure comprising a head portion, a rear portion and a deformable portion connecting the head portion and the rear portion. The deformable portion is deformable in elongation/contraction along a main axis connecting the head portion and the rear portion. The head portion includes at its surface at least one propulsion cilium, one end of the at least one propulsion cilium being attached to the head portion and the other end of the at least one propulsion cilium being a free end configured to move freely in the viscous material. The propulsion structure further includes a motor configured to actuate sequentially elongation/contraction cycles of the deformable portion.

Microrobot configured to move in a viscous material

This system for real-time localization of a millimetric or submillimetric object, such as a microrobot, in a viscoelastic medium, in particular in an organ of a subject such as a brain, a liver or a pancreas, includes: at least one bubble configured to be attached to said object, the or each bubble having a hermetic envelope filled with a gas; at least one ultrasound transducer configured to emit initial ultrasound signals and to detect deflected ultrasound signals deflected at the surface of the bubble(s); a processing unit in communication with the ultrasound transducers and configured to generate localization data of the object from localization data of the bubble(s) based on the deflected ultrasound signals detected by the ultrasound transducers.
