Systems and methods present multiple images of a three-dimensional model, including a three-dimensional representation of an anatomic structure and a representation of a medical device relative to the anatomic structure, on a graphical user interface. The multiple images correspond to different views (e.g., in multiple, different planes) of the three-dimensional model to provide complementary spatial information regarding a position of the medical device relative to the anatomic structure during a medical procedure performed on the anatomic structure. Such complementary spatial information can, for example, provide spatial context to facilitate controlling the position of the medical device relative to the anatomic structure during the medical procedure.

Disclosed are access devices that can be used to safely guide instruments, such as EP ablation catheters, to a therapy site such one within the pericardial space of the heart. The access devices include integrated visualization, illumination, stabilization, and safety features in a single platform that can, for example, more safely and efficiently identify and ablate several ventricular tachycardia (VT) locations on the left ventricle of the heart.

Non-contact ultrasound imaging system. The system includes a pulsed near infrared scanning laser source for illuminating a surface of a structure to generate ultrasonic elastic waves that propagate into the structure. A laser Doppler vibrometer measures vibration of the surface caused by the propagating ultrasonic waves in the structure and a data acquisition module processes data from the vibrometer to construct an image of the structure.

Various example embodiments of the present disclosure provide systems and methods for the dynamic correction and reduction of thermal variations in skull-induced aberrations during a focused ultrasound therapy procedure. Unlike conventional approaches involving static corrections for skull-induced aberrations, various example embodiments of the present disclosure employ ultrasound detection and a skull thickness estimate from volumetric image data to intermittently and dynamically determine corrections for skull-induced aberrations, such that aberration correction reduction is updated intraoperatively and maintained despite local thermally-induced changes in the speed of sound of the local skull region due to intraoperative intracranial heating. Furthermore, in some example embodiments, a measure dependent on the speed of sound with the skull is intraoperatively determined and compared to a previously determined value of the measure to determine a change in the skull temperature, based on a pre-determined relationship between changes in the measure and changes in skull temperature.

Method for image acquisition in an ultrasonic biometric imaging device, the device comprising a plurality of ultrasonic transducers arranged at a periphery of a touch surface along one side of the touch surface, the method comprising: determining a target area of a touch surface; identifying a blocking feature preventing ultrasonic wave propagation in the touch surface such that the blocking feature creates a blocked region in the touch surface where image acquisition is not possible; determining that the target area at least partially overlaps the blocked region; dividing the transducers into a first subset and a second subset, the first and second subset being defined in that ultrasonic waves emitted by the respective subset reaches the target area on a first and second side of the blocking feature; and capturing an image of the biometric object using transmit and receive beamforming.

A probe for ultrasound treatment of skin laxity are provided. Systems and methods can include ultrasound imaging of the region of interest for localization of the treatment area, delivering ultrasound energy at a depth and pattern to achieve the desired therapeutic effects, and/or monitoring the treatment area to assess the results and/or provide feedback. In an embodiment, a treatment system and method can be configured for producing arrays of sub-millimeter and larger zones of thermal ablation to treat the epidermal, superficial dermal, mid-dermal or deep dermal components of tissue.

Embodiments provide an ultrasound treatment system. In some embodiments, the system includes a removable transducer module having an ultrasound transducer. In some embodiments, the system can include a hand wand and a control module that is coupled to the hand wand and has a graphical user interface for controlling the removable transducer module, and an interface coupling the hand wand to the control module. The interface may provide power to the hand wand or may transfer a signal from the hand wand to the control module. In some embodiments, the treatment system may be used in cosmetic procedures on at least a portion of a face, head, neck, and/or other part of a patient.

The present invention relates to a monitoring apparatus for monitoring an ablation procedure. The monitoring apparatus comprises an ultrasound signal providing unit for providing an ultrasound signal that depends on received echo series of an object that is ablated. The monitoring apparatus further comprises an ablation depth determination unit for determining an ablation depth from the provided ultrasound signal. The ablation depth can be determined directly from the ultrasound signal and is an important parameter while performing an ablation procedure. For example, it can be used for determining the progress of ablation within the object and for determining when the ablation has reached a desired progression.

A system and method is disclosed for measurement of pulse wave velocity of a vessel. An intravascular device comprises a first and a second marker provided at different locations along the length of the intravascular device of which positions are localizable by a tracking apparatus. The intravascular device provides plurality of measurements along the length of the vessel, while the intravascular device is moved from a first position to a second position, corresponding to a first and a second time. At the second time the position of the first marker in the vessel corresponds to the position of the second marker at the first time. The pulse wave velocity value of the vessel is ascertained based on measurements associated for the first time and the second time from the plurality of measurements and based on the distance between the locations of the two markers along the length of the intravascular device.

The present invention proposes an ultrasound system and a method of detecting lung sliding on the basis of a temporal sequence of ultrasound data frames of a first region of interest. The first region of interest includes a pleural interface of a lung. A sub-region identifier (410) is configured to identify, for each of the ultrasound data frames, a sub-region of a scanned region of the ultrasound data frame, the sub-region comprising at least part of the pleural interface; a lung sliding detector (420) is configured to derive a parametric map for the sub-region on the basis of at least two ultrasound data frames of the temporal sequence, parametric values of the parametric map indicating a degree of tissue motion over the at least two ultrasound frames; wherein the lung sliding detector is further configured to extract data of the sub-regions from the at least two ultrasound data frames, and to derive the parametric map on the basis of the extracted data.
