Abstract: The invention concerns a preoperative probe (2) for guiding an ablation tool, comprising a sensing head (21), said sensing head including: at least one optic fiber (2121, 2123) for receiving and guiding a signal emitted, by radioactive tracers and/or fluorescent molecules in a tissue zone, to an analyzing equipment (32), fixing means (2112) for mounting the head (21) on the ablation tool (1), such that the ablation tool is capable of extracting a portion of tissue in the tissue zone emitting the signal.

Abstract: A peroperative probe for guiding a manual excision tool. The probe includes a detection head, an optical fiber for the reception and guidance of a signal emitted by radioactive tracers and fluorescent molecules in a tissue area, a photo-detector for converting the emitted signal into an electrical signal, a transmitter for transmitting information carried by the electrical signal to an analysis equipment, and a fastener for attaching the probe onto the manual excision tool, so that the excision tool can be used to remove a portion of tissue from the tissue area emitting the signal.

Abstract: An apparatus is disclosed for use on a collimator of a radio-imaging device. The system includes a stack of plates provided with perforations, the thickness (d) of the plates being less than the diameter of the perforations in the internal entry face of the collimator. The thickness of the span between the perforations is made greater than the thickness of the plates.

Abstract: A non-invasive analysis device including a plurality of sensors (110) combined with collimating structures (120) having a common source focus (O) and processing means (300) providing an AND-type combinational logic function of the output of the sensors (110) for sensing two coincidently transmitted beams that are at least slightly angularly correlated.
