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

The present invention relates to a device for determining the position of a plurality of objects that are simultaneously trapped by a single laser beam, characterized in that the device comprises:—a laser source for emitting a laser beam, an actuation system for a three-dimensional deflecting of the laser beam between several trapping points,—a microscope objective for focusing the laser beam coming from the actuation system on the trapping points,—a sample chamber including the objects to be trapped on the trapping points,—a light source for lighten the sample chamber, and—a camera for determining the position of each of the trapped objects, said camera being located between the laser source and the actuation system, so that the light emitted by the light source passes successively through the sample chamber, the microscope objective, the actuation system and the camera.

Device for determining the position of trapped objects in optical tweezers

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.
