  • Ultrasound image focusing method and relative ultrasound system
    Patent number: 7090641
    Abstract: The method comprises the phases of: sending a series of excitation ultrasonic signals to a volume being investigated, by means of an array of transducers aligned in a transverse direction (x), said ultrasonic signals propagating in depth in said volume according to a direction of propagation (y); acquiring, by means of said transducers, signals reflected from reflectors located in the volume being investigated; performing on said reflected signals a transform in the transverse direction from a spatial domain (x,y), defined by said transverse direction (x) and by said direction of propagation (y), to a first transformed domain; applying, in the transformed domain, a two-dimensional transformation, to straighten every curved image (Ip1, Ip2, Ip3) of a reflector in said volume being investigated and make it essentially orthogonal to the direction of propagation (y); compressing, in the transverse direction (x) each of the straightened curves (Im1, Im2, Im3) to concentrate said straightened image in a zone center
