  • Publication number: 20070197912
    Abstract: Method for scanning and analysing a three-dimensional structure by suitably processing signals representing waves, particularly ultrasonic waves reflected or transmitted by said three-dimensional structure, which processing involves restoring or analysing the three-dimensional structure on the basis of data read out of a field memory. The method comprises calculating, for each structural point, the field memory positions containing the signals detected by the detection elements, corresponding to the waves reflected or transmitted by said point, and data in the field memory is read out by a decoding curve. The method includes detecting the sign of the detected signals, detecting a useful zone of said decoding curve in which the signals at the same sign, and calculating the position and the point being analysed on the basis of an integration of the amplitude of the signals detected in the useful zone of the decoding curve.

  • Patent number: 5665054
    Abstract: A method for controlling an ultrasonic hyperthermia treatment apparatus is disclosed. The hyperthermia treatment apparatus utilizes ultrasound that is focused at a focal spot. The position of the focal spot relative to the transducer is varied, where the peak power of the focal spot and the degree of overlap between the various positions of the focal spot are such that the energy radiated during a shot at each point in the region scanned by the variation of the position of the focal spot represents an equivalent focal spot where the energy applied to the object to be treated is substantially equal to the energy needed to destroy the cell tissue.

  • Patent number: 5431621
    Abstract: A Process and device of location and destruction of an anatomic target includes the periodic emission of a focused treatment beam of elastic waves and an echographic image of the target formed in real time during the treatment period by means of an ultrasonic auxiliary beam carrying out a scanning substantially centered in a symmetry plane of the focused treatment beam. Also displayed superimposed on the target image is a mark showing the theoretical position of the focal point of the treatment beam. Selection of the image forming echoes reflected from the target as a function of the coordinates of the region of impact of the auxiliary beam with respect to the echographic source is effected and the treatment and auxiliary sources are simultaneously displaced under the control of signals derived from the selected echoes until the coincidence between the image of the mark and the image of the target object is reached where the treatment beam emission is then triggered.
