A medical imaging device connector assembly for connecting a medical imaging device to a terminal of a medical imaging system is provided. The medical imaging device connector assembly includes a top housing having a first base cutout; a bottom housing configured to couple to the top housing, the bottom housing including a second base cutout; a base housing positioned within the first and second base cutouts; a plurality of printed circuit boards (PCBs) disposed between the top housing and the bottom housing; an electrical connector positioned within the base housing; and an elastic seal member surrounding a circumference of the base housing. When the top housing is coupled to the bottom housing, the elastic seal member is compressed by the plurality of PCBs in a first direction and by the top and bottom housings in a second direction perpendicular to the first direction to prevent fluid ingress.

Disclosed in the application is a handheld three-dimensional ultrasound imaging system and method, comprising a handheld ultrasound probe, used for scanning and obtaining an ultrasound image; a display, control and processing terminal, connected to the handheld ultrasound probe wiredly or wirelessly. The handheld ultrasound imaging system and method of the application further comprises: a handheld three-dimensional spatial positioning system, connected to the handheld ultrasound probe, moving with the movement of the handheld ultrasound probe, connected to the display, control and processing terminal wiredly or wirelessly, and used for independently positioning the three-dimensional position of the handheld ultrasound probe. By means of the handheld three-dimensional ultrasound imaging system and method of the present application, the large spatial positioning system in an existing three-dimensional ultrasound imaging system is changed into a portable spatial positioning system that can be used at any time, so that handheld three-dimensional ultrasound imaging can be widely applied.

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.

Disclosed is a device for medical imaging, such as intravascular ultrasound (IVUS) imaging. The device includes a printed circuit board and an enclosure configured to disperse heat generated by the printed circuit board. The enclosure comprises a first heat spreader coupled to and in thermal contact with the printed circuit board, a second heat spreader in thermal contact with the first heat spreader at an interface such that the heat is distributed between the first heat spreader and the second heat spreader across the interface, a first cover portion coupled to and in thermal contact with the first heat spreader; and a second cover portion coupled to and in thermal contact with the second heat spreader, wherein the first cover portion is coupled to the second cover portion to form the enclosure.

A vehicle allocation service system includes an acquisition unit configured to acquire biological information and positional information of a user, a selection unit configured to select a moving object to be provided to the user based on the biological information, a decision unit configured to acquire priority added to a satisfied condition of the biological information of the user and decide an order of vehicle allocation for the selected moving object according to the priority, and an instruction unit configured to instruct the selected moving object to move according to the positional information.

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.

A method and system is for assisting a user in positioning an ultrasound probe relative to a subject's body. In use, the user moves the probe through a series of positions, and ultrasound image data is captured for each position, the data at each position corresponding to a particular imaging view of the anatomical region being imaged. An assessment procedure (16) is operable to process ultrasound data for different imaging views, and to determine for the data for each view a rating, representative of the suitability of the data for that view for observing one or more anatomical features or deriving one or more clinical parameters from the data. Guidance feedback is generated (18) for the user for assisting the user in positioning the probe, wherein the guidance feedback is based on a history (26) of image view quality over time over the course of the imaging procedure. For example, a trend in image view quality over time may be determined and output to a user, from which the user can quickly tell whether they are moving toward (in the case of increasing quality) or away from (decreasing quality) an optimum imaging position.

A system for creating customized learning content for ultrasound simulators using materials from an existing library of curated content including images, volumetric data sets, and metadata, or otherwise acquired, overcoming numerous challenges to ultrasound education and training, including the ability to seamlessly create real-patient based ultrasound training curriculum, the creation of an expansive library that that represents multiple pathologic conditions, and the dissemination of training content to multiple users in an asynchronous manner.
