DISTANCE-DETERMINING METHOD AND TREATMENT APPARATUS WHICH USES SAID METHOD

摘要

The invention relates to a method of determining the real distance between the emission/reception face (212) of an imaging probe (2) and a target site, whereby the probe emits and receives waves through a propagation medium and a living tissue. The inventive method comprises the following successive steps consisting in: determining the theoretical distance between the face and the target site when the face is only separated from the target site by the living tissue; determining a distance correction factor resulting from the fact that the waves emitted and received have passed through the propagation medium; and applying the correction factor to the theoretical distance in order to obtain the real distance.
