The invention discloses a plaque psoriasis severity grading system and a plaque psoriasis severity grading method. The plaque psoriasis severity grading system comprises a case inclusion module used for selecting patients meeting plaque psoriasis western medicine diagnosis standards; the ultrasonic examination module is used for carrying out ultrasonic examination on the typical diseased part of the patient by an ultrasonic physician to obtain a high-frequency ultrasonic index; the scoring module evaluates the skin lesion of the patient and gives an improved PASI score of local lesion; the model building module takes the local improved PASI score as a dependent variable, takes a high-frequency ultrasonic index as an independent variable, adopts a stepping method to screen out factors having significant influence on the local improved PASI score, and builds a severity grading model; the verification module performs internal verification on the constructed severity grading model by using a neural network multilayer perceptron, and evaluates the prediction performance of the model; and the output module is used for visualization and output. The invention provides a new and effective technical means for grading the severity of the plaque psoriasis, and has important clinical application value and popularization prospect.

Disclosed examples generally relate to a robot arm-based ultrasound or echocardiography scanning system configured to mitigate limitations associated with conventional manual scanning, including sonographer strain, restricted field-of-view, and low signal-to-noise image quality. In such examples, the patient is scanned using a transducer mounted on and manipulated by a robot arm. The cardiac structures of subjects are imaged from multiple positions using a 2D and 3D echocardiography scanning system.

The invention discloses a portable ultrasonic probe and wrist fixing device, and relates to the field of ultrasonic probe auxiliary equipment. According to the portable ultrasonic probe and wrist fixing device, by arranging the mounting base, the rotating assembly, the direction adjusting assembly and the ultrasonic probe, when ultrasonic image diagnosis needs to be conducted on the wrists of a large number of patients, the mounting base can be mounted on the arms of the patients, and after the rotating assembly is started, a sliding plate can slide on a baffle ring; at the moment, the sliding plate can drive the direction adjusting assembly and the ultrasonic probe to move, the ultrasonic probe is attached to the wrist of the patient to move, image data of the wrist of the patient is collected, the device structure can operate automatically, the technical requirement of ultrasonic image probing operation for an ultrasonic physician can be lowered, and the working efficiency is improved. The acquisition speed of image data of the wrist of the patient can be remarkably increased, the equipment is small in size, a user can conveniently carry the equipment to various scenes for use, and the requirement for batch diagnosis of the patient is met.

An ultrasound scanner scans a patient. The scan data is checked for an optimal view as a subpart of the scan. Where the field of view does not include the optimal view, the scan is repeated with a different spatial extent. Where the field of view does include the optimal view, then the scan data for that optimal view is used to generate an image. Both the view and the overall or broader scan are controlled together so that a sonographer may place the transducer at an approximate location to still provide a precise view.

This invention provides an intelligent image measurement and navigation method and system for transcatheter aortic valve replacement (TAVR), relating to the field of medical auxiliary diagnosis. Utilizing a dual-temporal collaborative repair strategy, it can use the texture information of clear temporal phases to complete the anatomical details of blurred temporal phases, obtaining complete anatomical boundaries even under imperfect cross-sections. This significantly reduces the time and frequency of physical probe adjustments during surgery, lowering the reliance on the operational skills of anesthesiologists or sonographers. Through cascaded positioning with anatomical region locking, and using a probability field strength prior forced algorithm to focus on high-probability anatomical structures, it shields background noise that is easily interfered with by the human eye, ensuring the objectivity and consistency of measurement results. This allows less experienced surgeons to achieve measurement accuracy consistent with senior experts, providing standardized data support for valve model selection. It can intelligently filter out motion interference, ensuring the safety of intraoperative navigation, and its sub-pixel accuracy meets the requirements of refined TAVR surgery.
