Abstract: Internal bleeding systems, devices, and methods are disclosed that include a sensing module and a processing module. The sensing module has an ultrasound module and a communication module. The ultrasound module emits and receives ultrasound energy to and reflected from tissue in a patient and generates a reflected energy signal. The communication module transmits the reflected energy signal to the processing module. The processing module analyzes the reflected energy signal to determine if it indicates the presence of blood from internal bleeding in the patient.

Abstract: A computer specific system for receiving a plurality of medical imaging specific 3D patient specific data sets from different 3D data sources, for a patient receiving reconstructive surgery, locating and applying a plurality of landmarks to each data set, and performing an overlay analysis procedure that aligns the 3D data sets from the different 3D data sources to create a 3D medical image representation of the patient's tissue. The 3D representation can be used to create 3D models for use by surgeons to perform reconstructive surgical procedures.

Abstract: An ultrasound image system is provided. The ultrasound image system includes an ultrasound probe and a processing circuit. The ultrasound probe includes a substrate, a first transducer array and a second transducer array. The first transducer array is fixed disposed on the substrate and configured to receive a first ultrasound signal The second transducer array is fixed disposed on the substrate and configured to receive a second ultrasound signal. Each of the first transducer array and the second transducer array includes a plurality of ultrasound transducer elements arranged along a first direction. The ultrasound transducer elements of the first transducer array are interleaved with the ultrasound transducer elements of the second transducer array. The processing circuit is coupled to the first transducer array and the second transducer array and is configured to generate an ultrasound image signal according to the first ultrasound signal and the second ultrasound signal.

Abstract: The invention provides an ultrasound processing unit. A controller (18) of the unit is adapted to receive ultrasound data of an anatomical region, for example of the heart. The controller processes the ultrasound data over a period of time to monitor and detect whether alignment of a particular anatomical feature (34) represented in the data relative to a field of view (36) of the transducer unit is changing over time. In the event that the alignment is changing, the controller generates an output signal for communicating this to a user, allowing a user to be alerted at an early stage to likelihood of misalignment and loss of imaging or measurement capability.

Abstract: A positioning fixture for use with an ultrasound transducer comprising a base having a planar bottom surface and top surface, each having two long edges and two short edges, the top surface facing away from the bottom surface; first and second echogenic targeting bands recessed below the bottom surface of the housing; a pair of long sidewalls provided on and extending orthogonally from the top surface, one long sidewall of the pair of long sidewalls attached to each of the two long edges; a guide release on the top surface, attached to one of the two short edges on the top surface; a long axis needle guide on the top surface, attached to another of the two short edges; and a receptacle cooperatively defined by the pair of long sidewalls, the guide release and the long axis needle guide, the receptacle sized to accommodate the ultrasound transducer.

Abstract: The present invention addresses the problem of providing a muscle activity measurement device and a muscle activity measurement method which make it possible to measure the muscle activity of an object to be sensed with increased accuracy. The muscle activity measurement device is provided with a magnetic sensor unit which senses a magnetic field generated from a living body. The muscle activity measurement device identifies an installed direction of the muscle activity measurement device, and includes an indication, on a surface of a container, which comprises identification information for installing the muscle activity measurement device in such a way that a magnetism sensing direction X of the magnetic sensor unit and the direction in which the muscle fibers of the living body as the object to be sensed extend are substantially orthogonal to each other.

Abstract: The disclosed devices, systems and methods measure non-invasive blood pressure in a patient. Energy emissions, such as ultrasound or light, are emitted into tissues of the patient. The emitted energy reflects from various tissues, such as flowing blood and vessels, and can be detected, or received, to generate a reflected energy signal or data. The reflected energy can be processed, such as by using a constitutive equation, to calculate the blood pressure.

Abstract: The method provides for the following steps: —acquiring data indicative of an ultrasound machine comprising: a base unit, a probe associated with the base unit, and a needle guide associated with the probe for guiding needles in a volume subjected to ultrasound imaging by means of said probe and said base unit; —from a database, retrieving information associated with said ultrasound machine; —displaying, on a monitor, an ultrasound image acquired by means of the base unit; —superimposing, to the ultrasound image on the monitor, a set of guide traces for guiding the insertion of needles in the volume subjected to ultrasound imaging, said guide traces being coordinated with the acquired ultrasound images by means of the information retrieved from the database.

Abstract: A method of treating colorectal cancer included placing a high intensity focused ultrasound (HIFU) probe proximate a designated treatment volume at one of the colon and the rectum of a patient. The method further includes delivering HIFU via the HIFU probe at a frequency of at least 1 mHz for at least 3 seconds to raise a temperature of a first portion of the designated treatment volume to above 65° C., thereby ablating the first portion and causing a tissue defect within the designated treatment volume. The method further includes applying a nonablative dose of energy via the HIFU probe to a second portion of the designated treatment volume to provoke stem cell homing in the second portion, thereby encouraging tissue regrowth.

Abstract: A method, including receiving from a sensor affixed to a probe, signals output by the sensor in response to a calibrated magnetic field, and estimating, using calibration data, location coordinates of the sensor. Using the calibration data and the estimated location, an estimated vector including orientation coordinates is computed, and updated orientation coordinates that best fit the received signals to the estimated vector are computed for the estimated location. Based on the updated orientation, updated location coordinates that best fit the received signals to the estimated vector are computed. The steps of computing the vector, computing the orientation, and computing the location and monitoring changes in the updated location are repeated until the changes are linear. Upon the changes being linear, a final location of the sensor is computed using a linear projection from the updated location, and a position of the probe is presented based on the final location.
