An overlay system can include a substantially planar overlay base including a top side. The base can define a handle receptacle, for instance at a first end of the base. The handle receptacle can include a handle capture section optionally having a tapered profile. A centrally located elongated guide can extend longitudinally along the top side of the base to guide translational movement of the ultrasound probe holder along a longitudinal axis of the base. A handle can be configured to be attached and detached, by a user, with the handle receptacle of the base. The handle can define a channel optionally having a wedge profile. The wedge profile of the handle can correspond to the tapered profile of the handle receptacle. Engagement of the channel to the capture section of the handle receptacle can attach the handle to the base.

The present invention provides an ultrasound three-dimensional (3D) full-body tomography system, comprising an ultrasound guided wave medium container, an ultrasound probe array, and an ultrasound tomography device. The ultrasound guided wave medium container has a detection space, wherein the detection space is filled with a guided wave medium in order for a subject's body to be immersed in the guided wave medium. The ultrasound probe array is provided in the ultrasound guided wave medium container and comprises a plurality of probe units, wherein the probe units are integrated into an annular array and are arranged along a periphery of the detection space. The ultrasound tomography device is for constructing a 3D image model based on data fed back from each pixel of the ultrasound probe array.

The object of the invention is a skeletal method utilizing electromagnetic waves to be utilized at least in one of skeletal actuation, skeletal detection and skeletal therapy. In the method is performed at least one of first and second method steps, where in the first method step is generated by means of electromagnetic waves at least one mechanical wave in at least one generation location into the skeleton through soft tissue. In the second method step is detected by means of electromagnetic waves skeletal vibrations due to at least one mechanical wave, is recorded the detected at least one mechanical wave in at least one recording location to form mechanical wave information, and distance of said at least one recording location from said at least one generation location is known, and further in the second method step is determined skeletal properties based on at least one recorded signal.

The speed of sound data corresponding to transmission of ultrasound through a cancerous lesion is different than the speed of sound data corresponding to transmission of ultrasound through a benign lesion. The system can assign a coloration to a speed of sound image according to the speed of sound through the tissue as obtained from quantitative transmission ultrasound. The shape indicative of a lesion can be identified through the reflection data with the type of lesion identifiable by the coloration from the speed of sound data.

The present disclosure directs to a system and method for automated positioning of a subject. The method may include obtaining a scout image of a subject when the subject is positioned at a first position in an apparatus. The method may also include determining location information of a reference structure of the subject based on the scout image. The method may also include determining an offset between the first position of the subject relative to a characteristic point of the apparatus according to the location information of the reference structure. The method may further include moving the subject to a second position based on the offset. The method may still further include performing, using the apparatus, a procedure relating to a target structure of the subject located at the second position.

A system for performing an ultrasound scan of cellular tissue includes an ultrasound scanning device having an ultrasound probe, to generate cross-sectional images of the cellular tissue. A probe enclosure houses the ultrasound probe, has a bottom formed by a flexible membrane, is configured to hold an ultrasonic coupling material, and forms a pressurizable cavity adjacent the flexible membrane. An armature supports the probe enclosure and is configured to move the probe enclosure into a position where the flexible membrane is placed adjacent to and displaced by the cellular tissue. A probe positioning assembly supports the ultrasound probe within the probe enclosure and moves the ultrasound probe over the flexible membrane with a head of the ultrasound probe submerged in the ultrasonic coupling material, the ultrasound scanning device generating the cross-sectional images of the cellular tissue as the probe positioning assembly progressively moves the ultrasound probe over the flexible membrane.

A method for identifying and locating at least one nerve in a target region is disclosed. In the method, an image detector is used to scan the target region according to a predicted nerve trend from a nerve identification program and capture 2D cross-sectional images of subregions of the target region, and the nerve identification program is utilized to identify' whether the 2D cross-sectional images are captured of the target nerve. When the nerve identification program identifies the 2D cross-sectional images are the images of the target nerve, a 3D image showing a 3D nerve structure is constructed from the 2D cross-sectional images based on 3D image reconstruction technique.

A device for limb detection includes a circular guide means and a carrier. The carrier is provided to carry an image detector and the circular guide means includes a slide mechanism integrated to the carrier. The slide mechanism and the carrier can move back and forth around a horizontal axis passing through the circular guide means such that they are beneficial for the image detector to detect the limb.

A device for fixing the outer boundaries of a region of body tissue in a secondary plane (and optionally in a tertiary plane) during medical imaging, examination, and/or intervention. The caliper device includes a caliper bar with two sliding caliper arms that provide fixation of the region of tissue in the secondary plane. One embodiment provides tertiary fixation with a center plate fixator that extends from a center plate positioner. The caliper device is positioned around the region of body tissue within the primary plane fixation instrumentation. The caliper arms (and optionally, the center plate fixator) move together to thicken the region of tissue between them. The device is preferably constructed of radiotransparent material and for single-use applications.
