Abstract
Official abstract text for this publication.
A calibration apparatus includes a fixture, which is coupled to accept a probe so that a distal tip of the probe presses against a point in the fixture and produces first measurements indicative of a deformation of the distal tip relative to a distal end of the probe, in response to pressure exerted on the distal tip. A sensing device is coupled to the fixture and is configured to produce second measurements of a mechanical force exerted by the distal tip against the point. A calibration processor is configured to receive the first measurements from the probe, to receive the second measurements from the sensing device and to compute, based on the first and second measurements, one or more calibration coefficients for assessing the pressure as a function of the first measurements.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for calibration, comprising: exerting a measurable force on a probe having a distal tip, the measurable force being directed at an engagement angle relative to a reference base angle, so as to cause deflection of the distal tip relative to a distal end of the probe; determining the engagement angle; determining the exerted force; receiving from the probe a position measurement indicative of the deflection between the distal tip and the distal…
