摘要： PROBLEM TO BE SOLVED: To stably display a high-quality elastic image at any arbitrary time phase in the elastic image diagnosis. SOLUTION: The ultrasonic probe has an automatic pressing means, which is structured to press a diagnosed section of a subject with a prescribed pressure by moving in the direction perpendicular to the contact surface of the subject. Accordingly, a pressing stage can be automatically moved vertically in a fixed direction at a desired constant speed, so that high-quality elastic image data can be obtained at an arbitrary hour. Furthermore, as the reproductivity of the pressing motion can be held, such a problem that the quality of the elastic image depends on an inspector can be avoided. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide an operator with operational information on pressurization to obtain proper elastic images. SOLUTION: This ultrasonic diagnostic equipment, which measures displacement values in each part based on two tomograms measured at different times by applying an external force by a pressurizing means to a subject, calculates an elastic modulus in each tissue based on the measured displacement data in each part, and displays the produced elastic images on a display means, is provided with a pressure determination means which determines whether the pressurizing operation by the pressurizing means has been properly performed or not by analyzing the displacement data. As a result, the displaying of the determination result by the pressure determination means on the display and the outputting through voice enable the operator to quickly adjust the pressurizing means to obtain proper elastic images.

摘要： PROBLEM TO BE SOLVED: To shorten calculation time of two-dimensional or three-dimensional displacement distribution and improve calculation accuracy of displacement distribution upon quantitative measurement of hardness of living tissue. SOLUTION: Ultrasonic echo signals before and after compression by an ultrasonic probe are respectively subjected to orthogonal detection to prepare envelope signals. Correlation factors between envelop signals before and after compression are calculated by scan lines respectively discrete by predetermined values in the axial direction in a three-dimensional correlation window, in the lateral direction orthogonally crossing the axial line, and in a slice direction orthogonally crossing the axial direction and the lateral direction to calculate a position wherein the correlation factor reaches the maximum. Phase difference between ultrasonic signals before and after compression at the position is calculated to obtain displacement information in the axial direction, the lateral direction, and the slice direction in the subject tissue accompanying compression based on the calculated position and phase difference. Two-dimensional or three-dimensional strain is obtained based on the displacement information in the three directions. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To estimate displacement distribution corresponding to lateral displacement and to reconfigure elastic modulus distribution only from distortion distribution in the direction of ultrasonic beam (axial direction). SOLUTION: A correlation computing means calculates the corelation between signals before and after compression of a subject tissue using an envelope signal outputted from an orthogonal detecting means. At this time, since calculation of correlation at intervals of samples becomes an enormous amount of calculation, the correlation computing means calculates a correlation coefficient at every scan line discretized by each designated value in the axial direction in a two-dimensional correlation window and in the lateral direction intersecting perpendicularly to the axial direction. Thus, the calculation amount can be decreased remarkably to enable real-time display. An elastic modulus estimating means divides the subject tissue into a finite number of rectangular parallelepiped elements for three-dimensional finite element modeling, supposing that the subject tissue is isotropic elastic body and near non-compressive, and estimates elastic modulus distribution information using distortion distribution information in an elasticity equation, supposing that elastic modulus, stress and distortion are uniform in each element.

摘要： PROBLEM TO BE SOLVED: To increase the processing speed of a circuit for executing basic algorithm of compound auto-correlation method. SOLUTION: A correlation computing means calculates the correlation between signals before and after compression of a subject tissue using an envelope signal outputted from an orthogonal detecting means. At this time, in performing correlation calculation at intervals of 1/2 wavelength, an orthogonal detecting envelope signal shifted by integral multiple of 1/2 wavelength in the axial direction is sequentially created using an orthogonal detected envelope signal, and the correlation coefficient between envelope signals before and after compression is calculated at intervals of 1/2 wavelength, whereby at the time of computing a correlation coefficient at intervals of 1/2 wavelength, repetition of orthogonal detecting operation is not needed so as to attain high-speed operation, simplify the circuit, remarkably decrease the calculation amount, and enable real-time display.
