Abstract: A method for evaluating a contact state of an ultrasound probe on the basis of soft tissue morphology.

Abstract: A data processing method performed by a first device includes: generating, in response to first service data satisfying a data uploading condition, a first bit array corresponding to the first service data; encrypting the first bit array through a data key to obtain a ciphertext bit array, the data key being generated by a second device in a data intersection application run in a trusted execution environment of the second device; and transmitting the ciphertext bit array to a blockchain node for forwarding to a second device, for the second device to decrypt, in the data intersection application through the data key, the ciphertext bit array to obtain the first bit array.

Abstract: A method for expanding functions of an ultrasonic imaging device, comprising: identifying and comparing functions of an integrated imaging device and a to-be-expanded ultrasonic imaging device; on the basis of a comparison result, configuring operating parameters and modes of the integrated imaging device and the to-be-expanded ultrasonic imaging device which serves as a host machine; enabling the integrated imaging device to be in communication with the host machine; and operating the integrated imaging device and displaying ultrasound data by means of a user terminal of the host machine. There is no need to make any changes to the hardware of the existing host machine, and new functions can be integrated into the existing device only by upgrading or making minor modifications to the software, such that a new application is derived from a traditional ultrasonic imaging device.

Abstract: A muscle training method and system for providing visual feedback by using ultrasonic imaging.

Abstract: A biological tissue elasticity dimensional detection method and detection system, and a storage medium. The detection method comprises: using an ultrasonic transducer array to acquiring an ultrasonic image of a target object, establishing a coordinate system of a sampling region of interest, and determining the number of sampling points and coordinate distribution positions thereof; in response to an external vibration excitation, collecting multiple elastic feature parameters at a designated coordinate position, and reconstructing a parameter value that contains spatial position information and a corresponding ultrasonic image, and comprising the synthesis, superimposition and fusion of maps, and simultaneously displaying. Multiple elastic feature parameters within a certain range can be measured by means of a single detection point, not only improving detection efficiency, but also minimizing sampling errors.
