Apparatuses, systems, and methods for controlling the sampling of tissue using a guidewire. In an illustrative embodiment, an apparatus includes a handle, a flexible dual lumen catheter couplable to the handle, and a guidewire guide disposed at a distal end of the flexible dual lumen catheter.

An apparatus includes an imaging probe and is configured for dynamically arranging presentation of visual feedback for guiding manual adjustment, via the probe, of a location, and orientation, associated with the probe. The arranging is selectively based on comparisons between fields of view of the probe and respective results of segmenting image data acquired via the probe. In an embodiment, the apparatus includes a sensor which guides a decision that acoustic coupling quality is insufficient, the apparatus issuing a user alert upon the decision.

An ultrasound imaging system includes a cine buffer in which image frames produced during an examination are stored. A processor is programmed to select one or more image frames from the cine buffer for presentation to an operator for approval and inclusion in a patient record or other report. The operator can accept the proposed image frames or can select one or more other image frames from the cine buffer. The processor may select image frames at spaced intervals in the cine buffer for presentation. Alternatively, the processor compares image frames in the cine buffer with one or more target image frames. Image frames that are similar to the target image frames are presented to the operator to confirm. Alternatively, image frames can be selected by the processor that contain a specific feature or that are similar to image frames that were previously selected by the operator when performing a particular type of examination.

A system for determining peripheral artery disease and method of use for determining the presence or absence of peripheral vascular disease and the severity of the disease in particular vascular segments. The System for determining peripheral artery disease and method of use includes a continuous wave Doppler transceiver which generates a digitized version of quadrature detected stereo audio and is coupleable to a waveform converter and processor. The waveform converter and processor provides filtering, time domain to frequency domain conversion, gain control, and statistical processing of the converted Doppler Stereo audio and is operationally coupled to a display for presenting results to a technician.

Provided is an ultrasound diagnostic apparatus including an ultrasound probe, an imaging section that images the subject on the basis of a reception signal output from the ultrasound probe to generate an ultrasound image, an image analysis section that performs image analysis using the ultrasound image, a movement detection sensor that detects and outputs a movement of the ultrasound probe as a detection signal, a movement amount calculation section that calculates a movement amount of the ultrasound probe in a case where an imaging inspection portion that is currently being imaged among a plurality of inspection portions of the subject is inspected, using the detection signal output from the movement detection sensor, and a portion discrimination section that discriminates the imaging inspection portion on the basis of an image analysis result in the image analysis section and the movement amount calculated by the movement amount calculation section.

Aspects of the technology described herein relate to guiding collection of ultrasound data collection using motion and/or orientation data. A first instruction for rotating or tilting the ultrasound imaging device to a default orientation may be provided. Based on determining that the ultrasound imaging device is in the default orientation, a second instruction for translating the ultrasound imaging device to a target position may be provided. Based on determining that the ultrasound imaging device is in the target position, a third instruction for rotating or tilting the ultrasound imaging device to a target orientation may be provided.

An ultrasound diagnostic apparatus and a control program for an ultrasound diagnostic apparatus. According to an embodiment, the ultrasound diagnostic apparatus includes an ultrasound probe that transmits and receives ultrasound waves to and from a subject in three dimensional space, a position sensor, and a processor. The processor is configured to determine whether or not a first region and a second region configure the same three dimensional region across a first scanning surface and a second scanning surface. The processor is configured to perform, based on the determining result, processing to obtain information representing the size of the three dimensional region in a direction intersecting the first scanning surface and the second scanning surface. The processor is configured to perform control for notifying the information.

A fully automated ultrasound apparatus includes a sensor or probe which can be initially manually attached to a side of the neck of a patient, an ultrasound interface to control the sensor and periodically acquire raw ultrasound data, a signal and image processing system to autonomously convert the raw ultrasound data into a measurement that is useful to physicians, and a display to relay the current measurements and measurement history to provide data trends. The sensor can include one or more ultrasound transducers built into a housing. A disposable component can serve to secure the sensor to the neck of the patient and to provide a coupling medium between the sensor and the skin of the patient.

According to one embodiment, an analysis apparatus includes processing circuitry. The processing circuitry configured to generate a harmonic signal and a fundamental wave signal based on a reception signal that is collected by an ultrasound probe, the harmonic signal corresponding to a harmonic component of a reflected wave of a ultrasound generated in the subject, the fundamental wave signal corresponding to a fundamental wave component of the reflected wave, calculate a first index value indicating tissue properties of the subject based on the harmonic signal, and calculate a second index value indicating the tissue properties based on the fundamental wave signal, and display an analysis result based on the first index value and the second index value.

A system for instrument guidance is disclosed. The system can include an instrument guide device and a transducer system. The instrument guide device can include an instrument guide and an instrument guide bracket that includes a magnet, and the instrument guide bracket can be removably attachable to the instrument guide. The transducer system can include an ultrasound probe bracket that is removably attachable to an ultrasound probe. Further, the instrument guide device can removably attach to the ultrasound probe bracket. The ultrasound probe bracket can further include a first sensor and second sensor. The first sensor can wirelessly track a position of the magnet to determine position data of the instrument guidance system. And the second sensor can provide power or disengage power to the instrument guidance device when the instrument guide is attached or detached, respectively.
