An ultrasound probe in combination with at least an operating unit such as a tracking sensor or receiver and/or a keypad and/or a surgical tool support, wherein the probe and the at least one operating unit are each one provided with one of two parts of a releasable joint, the said two parts of the joint being releasably engageable one with the other by magnetic force and by mechanical coupling.

Ultrasound probe and ultrasound system provided with said ultrasound probe

A method for automatically detecting of the probe which is selected for the use by the user without manual commands by the user and comprising monitoring the operational status of the probe by discriminating between probe not in use and probe in use by sensing at least the motion of the probe and by setting automatically a probe in an active status if a motion of the probe is sensed and setting the probe in an inactive status if the probe is stationary.

Method for driving an ultrasound probe, ultrasound probe and ultrasound system comprising said ultrasound probe

A method and system for two-dimensional shear wave elastography imaging (SWEI) that acquires B-mode ultrasound image of a region, selects an area of the B-mode image, automatically acquires two-dimensional shear wave elastography imaging data related to the selected area, and displays elasticity/velocity map on the selected area and optionally a reliability map. An algorithm takes as input one or combination of data sets selected from B-mode raw data or B-mode image data or elasticity/velocity map or reliability map or—raw two-dimensional shear wave elastography imaging data inside selected area, or two-dimensional shear wave elastography imaging data at an intermediate stage of processing like displacement curves over time or their peak features, and outputs the 2D coordinate of measure ROI center. Measure ROI overlapped on the B-mode image and/or on the elasticity map and/or on the reliability map is displayed. An elasticity parameter inside the measure ROI is computed, optionally weighted, and displayed.

A method for postural independent location of targets in diagnostic images acquired by multimodal acquisitions, compensating for deformation of soft tissues due to changing posture, includes generating a transition of a digital image of the inside of a target region from a first to a second position by correlating the position of markers placed on the external surface of the target region in a digital image of the inside of the target region and in a digital representation of the external surface of the target region acquired by optically scanning the external surface; and at a later time registering the diagnostic image of the inside of the target region, transitioned into the second position, with a diagnostic image of the same target region acquired with the target region in the second position by matching a second representation of the external surface of the target region in the second position without markers with the diagnostic image of the inside of the target region transitioned into the second position.

A method for tissue characterization by ultrasound wave attenuation measurements is provided that comprises: The disclosure relates also to an ultrasound system for carrying out the method.

Method for tissue characterization by ultrasound wave attenuation measurements and ultrasound system for tissue characterization

An ultrasound imaging method includes providing a digital representation of the shape of a surface or boundary of an anatomic region or organ; acquiring an ultrasound image by ultrasound scanning the anatomic region or organ; and combining the digital representation of the shape of the surface or boundary of the anatomic region or organ by registering the digital representation of the shape of the surface or boundary and the ultrasound image as a function of the difference in position of selected reference points on the digital representation of the surface or boundary and on the ultrasound image, the position of the reference points on the ultrasound image being determined by tracking the probe position at the reference points at the anatomic region or organ of a real body and in a spatial reference system, in which the anatomic region or the organ of the real body is placed.

A device and method for guiding surgical tools by ultrasonic imaging having means for acquiring a time sequence of 3D ultrasonic images of a target area, means for determining and tracking the position and orientation of a surgical tool and means for defining the direction of a characteristic axis of the tool corresponding to the detected position and orientation of the tool. The device further having means for determining the position of a working end of the tool along the characteristic axis, means for determining the relative position in space of each 3D image and the direction of the characteristic axis corresponding to each 3D image, and means for generating a 2D image defined by an image plane that intersects the corresponding 3D image of said time sequence.

Provided is a method and arrangement for registering first image data of a first stream with second image data of a second stream. The image data include image information about at least one organ, wherein a shape and/or position of the organ is cyclically changing: Each of the streams include a series of images of the at least one organ at a plurality of different discrete stages of the cyclic change so that each image corresponds to one of the discrete stages. A phase variable defines the stage of the cyclic change and a phase value of the phase variable is assigned to each image within each stream, thereby defining the discrete stage represented by the image. A registration is determined for a pair of images selected by choosing or interpolating images from the first stream and second stream to which a same phase value is assigned.

Registering first image data of a first stream with second image data of a second stream

Method for ultrasound image acquisition includes defining a fixed frame of reference, with an origin of coordinates within a transmitter of a tracking system; detecting position and orientation of a probe relative to the frame of reference with a probe sensor of the tracking system coupled to the probe; detecting position and orientation of a body relative to the frame of reference with a reference sensor of the tracking system coupled to the body; calculating position and orientation of the probe with respect to the body; acquiring a set of 2D images constituting a 3D by transmitting an ultrasonic beam into the body and receiving echographic signals with the probe; iterating for a predetermined number of 3D image acquisitions; generating a panoramic 3D image by combining the 2D images based on information of position and orientation of the probe relative to the body for each 2D image acquisition.
