Title:
An imaging device by picture acquisition rate optimization
Document Type and Number:
Japanese Patent JP6018086
Kind Code:
B2
Abstract:
The disclosure includes a method of acquiring high-resolution ultrasound images using an array of transducers using successive transmission matrices. Implementations include operations for determining inter-transducer correlation matrices of an area of interest and an unwanted area; determining a characteristic matrix of the area of interest from the product of the inverse of the inter-transducer correlation matrix of the unwanted area and the inter-transducer correlation matrix of the area of interest; calculating eigenvectors and values of the characteristic matrix to define a transmission matrix; adjusting the image acquisition rate and image quality in order to define eigenvectors for firing; multiplying a reception matrix comprising the acquired signals completed by data set to zero corresponding to the firings not effected by the inverse of the transmission matrix to obtain a complete data set; reconstructing a high-resolution image of the area of interest as in synthetic aperture echographic imaging methods.
