A system and method for determining an access trajectory to a target site to safely place a surgical access instrument (e.g., guide wire, dilator, cannula, etc.) through a tissue (e.g., muscle, fat, brain, liver, lung, etc.) without damaging nearby neurovascular structure is described herein. The trajectory determination system includes a nerve stimulation probe and a dilator guide having a plurality of guide channels and registerable to an operating table in a fixed orientation. Motor nerve stimulation (e.g., EMG, MMG) is performed with the stimulation probe positioned in each of said plurality of guide channels to generate a map of nerve locations within intervening anatomical structures (e.g., muscle, bone, etc.) between the dilator guide and the surgical target site. Available access pathways are determined based on the nerve location data and displayed on a display unit.

When a basic mode is selected, a basic processing block in an ultrasound diagnostic apparatus operates in real time, to generate a first display image array, and the first display image array is displayed on a display. When an extended mode is selected, necessary information is transferred from the ultrasound diagnostic apparatus to an external information processing apparatus, and an extended processing block in the external information processing apparatus operates in real time, to generate a second display image array. The second display image array is displayed on the display.

Ultrasound imaging tools are configured with rotation and deflection control. Methods of controlling an ultrasound imaging transducer may include advancing a distal end region of a catheter assembly to an anatomical region of interest, the catheter assembly may include a rotatable shaft carrying an ultrasound imaging transducer; and a deflectable shaft. Actuating a first actuator of a handle assembly may cause rotational movement of the rotatable shaft relative to the deflectable shaft, which thereby causes rotational movement of the ultrasound imaging transducer; and actuating a second actuator of the handle assembly to cause deflection of the deflectable shaft, where the handle assembly includes a handle body with an outer surface that can be gripped by a user, and where the first actuator and the second actuator are circumferentially disposed about a longitudinal axis of the handle body.

Transducer probes for ophthalmological instruments operating without the use of light (such as contact tonometers and ultrasound pachymeters)—whether structured substantially monolithically (as one piece) or in a hybrid or composite fashion (and, therefore, reversibly separable into constituent components)—the axially-located front transducer surface of which is surrounded by a ridge of material not representing the surface of the transducer, in which the overall front cornea-contacting surface of which is inwardly shaped to reduce or even completely avoid measurement errors associated with the use of conventionally-structured versions of probes traditionally use with such instruments. Ophthalmological instruments utilizing such probes and methods of use. Biological protection of eye during use of such instruments.

The disclosed embodiments relate to a portable ultrasound device. Specifically, the disclosed embodiments relate to an acoustic lens positioned at an ultrasound probe. The acoustic lens may be configured for impedance matching and signal attenuation. In one embodiment, ultrasound signal attenuation is provided by forming an acoustic lens as a solid admixture of signal attenuating particles in a polymer matrix.

A system for acquiring physiological data from a patient, the system comprising: a smartphone configured for wireless communication; an adapter for releasably mounting to the smartphone; a sensor module for releasably mounting to the adapter, the sensor module comprising at least one sensor for acquiring physiological data from the patient; and a software app running on the smartphone for (i) wirelessly controlling operation of the sensor module and wirelessly receiving the physiological data from the sensor module, and (ii) wirelessly communicating with a remote location.

A guidance system for guiding insertion of a needle into a body of a patient utilizes ultrasound imaging or other suitable imaging technology. The guidance system can include an imaging device including a probe for producing an image of the internal body portion target, such as a blood vessel. The imaging device can be configured to provide at least one indication of status via sensory feedback based on a determined position of the needle, for example via a plurality of light-emitting diodes located on the device. One or more sensors can be included with the probe that can sense a magnetic field associated with the needle. The system may include a processor that can receive magnetic field data sensed by the at-least-one sensor to determine the position of the needle. The system can also include a display that depicts the determined position of the needle.

A system and method for converting a commercial diagnostic ultrasound transducer into a medical training device that is used for simulated ultrasound training; or a system and method for adding a training option to a standard ultrasound diagnostic system by attaching a motion sensor accessory to the commercial diagnostic ultrasound transducer.

Apparatuses, systems, and techniques are provided for modular ultrasonic transducers and frame. An ultrasonic transducer array may include a modular ultrasonic transducer array frame. The modular ultrasonic transducer array frame may include mechanisms for the attachment of ultrasonic transducer modules to the ultrasonic transducer array frame. The ultrasonic transducer array may include ultrasonic transducer modules which may include arrays of ultrasonic transducer elements within the ultrasonic transducer modules. Two of the ultrasonic transducer modules may include arrays of ultrasonic transducer elements where the ultrasonic transducer elements are different between the two ultrasonic transducer modules.

Provided are an ultrasound system, an ultrasound probe, a control method of the ultrasound system, and a control method of the ultrasound probe capable of using various types of display terminals and causing the display terminal to perform processing according to computing power of the display terminal to be used.

An ultrasound system includes a display terminal and an ultrasound probe. The ultrasound probe has a reception circuit that generates a sound ray signal from a reception signal output from an oscillator array, an image generation unit that generates ultrasound image data from the sound ray signal, and a data selection unit that selects one of the ultrasound image data and intermediate data generated in a middle of generating the ultrasound image data, according to computing power of the display terminal, as data to be output to the display terminal. The display terminal to which the intermediate data is input generates the ultrasound image data from the intermediate data and displays an ultrasound image based on the ultrasound image data on the monitor.
