Title (EN) METHOD AND SYSTEM FOR DETECTING CONTACT BETWEEN AN OPTICAL PROBE AND TISSUE AND AUTOMATING TISSUE MEASUREMENT
(FR) PROCÉDÉ ET SYSTÈME POUR DÉTECTER UN CONTACT ENTRE UNE SONDE OPTIQUE ET UN TISSU ET POUR AUTOMATISER LA MESURE DU TISSU
Abstract:
(EN) Methods and apparatus initiate a procedure performed by a probe on tissue. A signal is obtained from the probe, the signal varying with changes in a proximity of the probe to the tissue. The obtained signal is analyzed by a controller to determine whether the probe is within a predetermined distance of the tissue. The controller initiates the procedure when it is determined that the probe is within the predetermined distance of the tissue. The obtaining and analyzing may be repeated until the probe is determined to be within the predetermined distance of the tissue. The analyzing may include comparing the obtained signal to a predetermined threshold.
(FR) L'invention concerne des procédés et un appareil qui lancent une intervention réalisée par une sonde sur un tissu. Un signal est obtenu depuis la sonde, le signal variant avec les changements de proximité de la sonde par rapport au tissu. Le signal obtenu est analysé par un dispositif de commande afin de déterminer si la sonde se trouve à une distance prédéterminée du tissu. Le dispositif de commande lance l'intervention lorsqu'il est déterminé que la sonde se trouve à la distance prédéterminée du tissu. L'obtention et l'analyse peuvent être répétées jusqu'à ce que l'on détermine que la sonde se trouve à la distance prédéterminée du tissu. L'analyse peut comprendre la comparaison du signal obtenu à un seuil prédéterminé.
