An ultrasound device (10) is disclosed comprising a transducer arrangement (110) and an acoustically transmissive window (150) over said arrangement, said window comprising an elastomer layer (153) having conductive particles dispersed in the elastomer, the elastomer layer having a pressure-sensitive conductivity, the ultrasound device further comprising an electrode arrangement (160) coupled to said elastomer layer and adapted to measure said pressure-sensitive conductivity. An ultrasound system and arrangement including such an ultrasound device are also disclosed.

Multi-arm robotic systems and methods for monitoring a target are provided. The system may include a first robotic arm configured to orient a first component and a second robotic arm configured to orient a second component. The first robotic arm and the second robotic arm may be co-registered. The first robotic arm may be caused to orient the first component at a first pose. The second robotic arm may be caused to orient the second component at a second pose. At least one image may be received from the first component and the second component.

A system for operating an ultrasound probe that is provided with sensor operation portions for operating the ultrasound probe that acquires ultrasound echo images of a blood vessel, and a control portion that controls operations of the sensor operation portions. The control portion may switch the arrangement of the ultrasound probe using the sensor operation portions between a first arrangement for acquiring an image of a cross section in the transverse direction of the blood vessel and a second arrangement for acquiring an image of a cross section in the longitudinal direction of the blood vessel.

A system for detecting a position of a long medical device includes a model acquisition portion that acquires a blood vessel model, a correspondence detection portion 1 that detects a position of a long medical device inserted into a blood vessel and detects a correspondence between the blood vessel model and the position of the long medical device, and a display portion that displays the position of the long medical device in association with the blood vessel model on the basis of a detection result of the correspondence detection portion.

Systems and methods for tracking a target volume, e.g., tumor, in real-time during radiation treatment are provided. The system includes a memory to store a pre-acquired 3D image of the anatomy of interest in a first reference frame and a processor, operative coupled with the memory, to receive, from an ultrasound probe, a set-up ultrasound image of the anatomy of interest in a second reference frame. The processor further to establish a transformation between the first and second reference frames by registering the set-up ultrasound image with the pre-acquired 3D image and receive, from the ultrasound probe, an intrafraction ultrasound image of the anatomy of interest. The processor further to register the intrafraction ultrasound image with the set-up ultrasound image and track motion of the anatomy of interest based on the registered intrafraction ultrasound image.

A system useful for performing ultrasound elastography of organs such as the liver allows efficient and robust data acquisition. The system may be applied to perform real-time, noninvasive ultrasound imaging of the liver in humans. Steady-state, shear wave absolute elastography is used to measure the Young's modulus of the liver tissue. This method involves the use of an external exciter or vibrator to shake the tissue and generate a shear wave. Accurate placement of an ultrasound transducer facilitates measurement of the tissue motion due to the shear wave. The stiffness of tissues in the region being imaged may be computed from the measured tissue motions. The following innovations address both vibrator and transducer placement, as well as some specific methods to ensure adequate wave propagation, in order to obtain accurate and consistent measurements.

According to various embodiments, there is provided a device including a processor configured to control a robotic system to autonomously position a transducer at a plurality of locations adjacent a subject's skull and to autonomously locate a window on the subject's skull within which an artery can be located, from which artery a signal can be returned to the transducer, the signal having an energy level exceeding a predefined threshold.

Prostate biopsy systems are provided that include a 3D ultrasound probe support configured to receive an ultrasound probe for transperineal imaging. One or more template grids can have a plurality of apertures extending therethrough to receive and guide a biopsy needle along a trajectory associated with respective apertures when the template grid is fixed to the support and the biopsy system is positioned in the perineal area of a patient. Patient-specific template grids can also be developed and produced. This system enables fully transperineal prostate biopsy (i.e. both imaging and needle placement are perineal) and eliminates the need for an external racking device for image fusion as well as needle tracking. In addition, it reduces the infection risk associated to transrectal approach.

Arrangements described herein relate to systems, apparatuses, and methods for a disposable kit containing medical items configured for a medical device including a head cradle to support a head of a subject, the disposable kit includes a container that encloses a head cradle pad configured to be affixed to the head cradle, at least one fiducial marker configured to be disposed on a location at the head of the subject, and at least one enclosure configured to cover a portion of the medical device.

A medical device for injecting fat while simultaneously allowing the injection site to be viewed with ultrasound. The device may comprise a handle with a front portion and a rear portion, a cannula having a cannula tip, extending from the front portion of the handle, and an ultrasound probe attached to the handle, the ultrasound probe comprising an ultrasound head. The ultrasound head is aligned with and spaced apart from the cannula tip, and remains so aligned during the injection process so that the injection area may be continuously viewed during the procedure.
