    摘要： An automated three dimensional mapping and display system for a diagnostic ultrasound system is presented. According to the invention, ultrasound probe position registration is automated, the position of each pixel in the ultrasound image in reference to selected anatomical references is calculated, and specified information is stored on command. The system, during real time ultrasound scanning, enables the ultrasound probe position and orientation to be continuously displayed over a body or body part diagram, thereby facilitating scanning and images interpretation of stored information. The system can then record single or multiple ultrasound free hand two-dimensional (also “2D”) frames in a video sequence (clip) or cine loop wherein multiple 2D frames of one or more video sequences corresponding to a scanned volume can be reconstructed in three-dimensional (also “3D”) volume images corresponding to the scanned region, using known 3D reconstruction algorithms. In later examinations, the exact location and position of the transducer can be recreated along three dimensional or two dimensional axis points enabling known targets to be viewed from an exact, known position.

    摘要： The present disclosure discloses an ultrasound pupil change-based anesthesia depth monitoring system, including: an ultrasound monitoring apparatus, which includes a head-mounted mounting member and two miniature ultrasonic probes, the two miniature ultrasonic probes being symmetrically arranged at both sides of the head-mounted mounting member, and the miniature ultrasonic probes abutting against the face and obtaining ultrasonic pupil images by means of ultrasonic waves; an ultrasound host, which includes a display, the ultrasonic pupil images obtained by the miniature ultrasonic probes being transmitted to the ultrasound host, and the ultrasound host processing the ultrasonic pupil images and displaying pupil images, real-time change values of diameters of pupils, and the like by means of the display; and a shading patch, which is applied to the eyelids. The present disclosure further discloses a detection method of an ultrasound pupil change-based anesthesia depth monitoring system. Compared with the prior art, the present disclosure has the advantages: A patient wears a head-mounted ultrasound monitoring apparatus, the miniature probes of the ultrasound monitoring apparatus monitor pupil changes while the patient is in an anesthesia/sedation state, thereby realizing real-time dynamic monitoring of an anesthesia depth.

    摘要： A system that is capable of performing a fully automated ultrasonic (US) scan. The subject that is undergoing the scan associates with the system and the scan is performed without any human intervention. The US probe comprises an US transducer that is configured to generate US signals and detect their reflections, to collect acoustic data during the scan. The US probe is moved by a probe-motioning unit that is affixed and is configured to move the US probe in up to six degrees of freedom according to the desired scan pattern that is determined by a processing circuitry of the system, i.e. a control unit. Therefore, any anatomical landmark of the eye can be scanned from any desired angle. The processing circuitry is configured to control the operation of the US probe and the probe-motioning unit to execute a desired scan pattern.

    摘要： What is provided are methods of analyzing at least one image of the anterior segment of an eye and for selecting an intraocular lens (IOL). The methods may include detecting at least one image from an anterior segment of the eye; identifying a location of a reference structure on the eye using a plurality of points of a landmark on the anterior segment of the eye; and calculating at least one quantitative dimension of the anterior segment of the eye using the reference structure. The newly identified landmarks and quantifiable dimensions improve the characterization of the anterior segment in order to better predict the position and movement of the intraocular lens. The improved methods for analyzing the imaging of the anterior segment of the eye allows for improvements in the refractive outcomes of cataract surgery, glaucoma procedures, refractive outcomes, and other eye-related diseases.

    摘要： A method and system for selecting an intraocular lens, with a controller having a processor and tangible, non-transitory memory. A plurality of machine learning models is selectively executable by the controller. The controller is configured to receive at least one pre-operative image of the eye and extract, via a first input machine learning model, a first set of data. The controller is configured to receive multiple biometric parameters of the eye and extract, via a second input machine learning model, a second set of data. The first set of data and the second set of data are combined to produce a mixed set of data. The controller is configured to generate, via an output machine learning model, at least one output factor based on the mixed set of data. An intraocular lens is selected based in part on the at least one output factor.
