摘要： Systems and techniques are provided for deicing/defrosting an ultrasonic sensor using frequency tuning. An example method can include determining that a radiation surface of a housing of an acoustic sensor includes a layer of frozen precipitation, wherein the housing contains a transducer configured to emit sound waves through the radiation surface and receive sound waves that are reflected from a target and pass through the radiation surface to the transducer; determining resonance frequency for sound waves that yields a shear stress on an interface between the radiation surface and the layer of frozen precipitation on the radiation surface, wherein the shear stress exceeds an adhesive shear strength of the layer of frozen precipitation; generating the sound waves having the resonance frequency; and removing the layer of frozen precipitation on the radiation surface based on the sound waves having the resonance frequency.

摘要： A testing apparatus has a phantom and a scanning mechanism. The scanning mechanism moves an ultrasonic probe in a scanning direction (x direction) while maintaining a contact state of the ultrasonic probe with the phantom. The phantom includes a heart simulated element simulating a heart which is a tissue of interest, and a simulated element simulating a tissue which is present at a periphery of the heart. A form of the heart simulated element changes continuously in the scanning direction. A change of a form thereof represents a change with respect to time of the heart.

摘要： Systems and methods for processing data acquired using ultrasound elastography, in which shear waves are generated in a subject using continuous vibration of an ultrasound transducer, are provided. The systems and methods described here can effectively remove motion artifacts associated with vibration of the ultrasound transducer, and can also remove the data sampling misalignment caused when a line-by-line imaging mode is used to acquire data, as is done by many conventional ultrasound scanners. Thus, the systems and methods described here provide techniques for transducer motion correction and for aligning motion signals detected by line-by-line scanning ultrasound systems.

摘要： A characteristic estimation unit analyzes a reception signal before detection processing among reception signals obtained by transmitting and receiving ultrasound waves with respect to a subject, to estimate a signal characteristic of the reception signal for each region in a data space of the reception signal. An image processing parameter decision unit decides an image processing parameter for enhancing an image quality of an ultrasound image based on the signal characteristic, for each region in the data space of the reception signal, which is estimated by the characteristic estimation unit. An image formation unit executes image quality enhancement processing of the ultrasound image based on the image processing parameter decided by the image processing parameter decision unit while forming the ultrasound image based on the reception signal after the detection processing.

摘要： A method and an analysis system for determining a state of a diaphragm of an ultrasound sensor during operation is disclosed. The diaphragm of the ultrasound sensor is excited with a first excitation signal in a predefined first frequency profile. Based on this, a first voltage profile, which depends on a frequency of the first excitation signal, is measured. Analogously, a second voltage profile is determined by applying a second excitation signal to the diaphragm and then carrying out a measurement. These two voltage profiles are shifted so that respective positions of maxima of the two voltage profiles are matched to each other in a predefined frequency range. A third voltage profile, which runs between the shifted first and second voltage profiles, is determined. Based on the third voltage profile, electrical parameters are determined by a model for continuous excitation of the diaphragm to determine the state of the diaphragm.

摘要： The present disclosure provides an ultrasonic imaging method and apparatus. The apparatus includes an ultrasonic signal emission source and a receiving array including ultrasonic signal receiving circuits; the method includes: turning on the source to perform emission of ultrasonic waves toward an object to be detected and causing the ultrasonic waves to propagate through the object, a depth-wise direction of which is along a propagation direction of the ultrasonic waves; after a first predetermined time period having elapsed since the source was turned on, turning on the receiving array to receive reflected echoes returning from a first section plane of the object to be detected perpendicular to the depth-wise direction; thereafter, turning off the receiving array, storing the reflected echoes by the ultrasonic signal receiving circuits and acquiring reflected echo signals, and successively reading the reflected echo signals from the ultrasonic signal receiving circuits during a reading time period.
