The present disclosure provides an ultrasound imaging apparatus and a method performed thereby. The ultrasound imaging apparatus includes an ultrasound transceiver module, a memory storing instructions, and at least one processor including processing circuitry, wherein, when the instructions are executed by the at least one processor individually or collectively, the ultrasound imaging apparatus is configured to: based on receiving a user input for obtaining an elasticity value of a region of interest (ROI) of a subject, repeatedly perform elasticity imaging on the ROI by the ultrasound transceiver module; when an elasticity image of the ROI is obtained by the elasticity imaging, identify an elasticity measurement ROI on the elasticity image; obtain an elasticity value from the identified elasticity measurement ROI; accumulate the obtained elasticity value as elasticity data; display information about a number of the accumulated elasticity data together with the obtained elasticity image; and obtain a next elasticity image by next elasticity imaging.

A device for measuring the stiffness of an organ of a subject, the measuring device including a measurement casing which includes a) a shear wave emitter adapted to generate a low-frequency elastic wave, and b) an ultrasound transducer adapted to acquire ultrasound signals to determine the stiffness of the organ based on the propagation of the generated low-frequency elastic wave, and an applicator extending from the measurement casing, the applicator being adapted to be placed against a part of a body of the subject, the applicator including a position maintenance device for maintaining the transducer perpendicular to the part of the body of the subject.

An intraoperative probe combines Raman spectroscopy, shear wave elastography (SWE), and photodynamic therapy (PDT), preferably in a single hand-held device with real-time machine learning analysis. The machine learning independently analyzes and then fuses the data from different modalities for real-time cancer diagnostic predictions. The approach herein leverages simultaneous (or near-simultaneous) collection and real-time processing of Raman and SWE data for immediate cancer diagnostic feedback and therapeutic action. The hand-held device is precisely configured to target the same focal point with three different modalities—Raman, SWE, and PDT—by positioning the modalities within the device into the same location, either with an array of mirrors or an automatic or manual rotation mechanism.

The application relates to the technical field of ultrasound, in particular to a shear wave-based elastic imaging system. The shear wave-based elastic imaging system comprises an elastic detection probe and a processor. The elastic detection probe measures the pressure applied on a target tissue by using a piezoelectric detection layer, obtains the applied pressure, and adjusts the applied pressure based on a communication connection with the processor. The processor acquires the applied pressure, identifies the applied pressure, and controls the elastic detection probe to adjust the applied pressure according to the identification result. The elastic detection probe transmits an ultrasonic signal and receives an ultrasonic echo signal when the applied pressure meets the target pressure requirement. The processor obtains ultrasonic data through the ultrasonic echo signal. The processing result of the target tissue is determined by processing the ultrasonic data. The application ensures that the detection is carried out when the applied pressure on the target tissue meets the target pressure requirement, thereby ensuring the accuracy of the processing result of the target tissue.

Methods and system for characterizing ligament properties using elastography are disclosed. An ultrasound system capable of performing shear wave elasticity imaging and / or supersonic shear imaging may retrieve one or more images from a proposed surgical site. The one or more images may be provided to a surgical planning system that identifies one or more properties of ligaments proximate to the surgical site. Musculoskeletal simulations may be performed using the identified properties to preoperatively identify a surgical plan. Preoperative identification of a surgical plan may enable a surgeon to select from more fine-tuning options for a joint replacement than conventional systems.

An elastography method (200) and an ultrasound imaging system are disclosed. The method (200) includes: transmitting a first push pulse toward a target tissue to generate a first shear wave (S210); transmitting a first ultrasound wave that tracks the first shear wave and receiving a first ultrasound echo to obtain first ultrasound echo data (S220); generating a first elastic image based on the first ultrasound echo data (S230); determining a target region in the first elastic image (S240); transmitting a second push pulse based on the target region to generate a second shear wave propagating within a target sub-tissue corresponding to the target region (S250); transmitting a second ultrasound wave that tracks the second shear wave and receiving the second ultrasound echo to obtain second ultrasound echo data, wherein the penetrating power of the second ultrasound wave is greater than that of the first ultrasound wave, and / or the penetrating power of the second shear wave is greater than that of the first shear wave (S260); generating a second elastic image based on the second ultrasound echo data (S270); and outputting the second elastic image (S280). This method (200) can solve the problem of insufficient penetration power during elastography.

A strain elastography method and an ultrasonic imaging device, the method comprising: controlling an ultrasonic probe to emit ultrasonic waves to a pressed target tissue region of a target object, and receive ultrasonic echoes to obtain ultrasonic echo data; generating an ultrasonic image based on the ultrasonic echo data, and obtaining first strain data based on the ultrasonic echo data and / or the ultrasonic image, performing mapping on the first strain data for strain elastography to obtain a first strain elastography image; determining an interference region in the first strain elastography image, and determining a target region based on the interference region, the target region being a region in the first strain elastography image other than the interference region; obtaining second strain data corresponding to the target region in the first strain data, performing mapping on the second strain data for strain elastography to obtain a second strain elastography image, and displaying the second strain elastography image. The method can exclude the influence of the interference region, and improve the quality and reliability of the strain elastography result.
