Embodiment Construction

[0113] Figure 6 The output of the first step of the method, which acquires an imaged region ZI of the medium M to be imaged, from which a region of interest D1 can be determined is shown diagrammatically.

[0114] When imaging moving structures is problematic, this region of interest D1 can be determined automatically by analyzing images or successive images in a device using the method of the invention.

[0115] The area of ​​interest D1 can also be determined manually by the operator selecting an area in the image area of ​​the next displayed image area.

[0116] Accordingly, the method of the invention comprises the step of determining an interactive sensor correlation matrix corresponding to the regions of interest and the regions of unwanted.

[0117] To this end, the method of the invention considers an array of N-dimensional acoustic sensors T1 to TN (eg, echographic probes), and a region of interest D, the region in space to be imaged.

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.

Description

technical field [0001] The field of the invention is echographic imaging. The present invention relates to methods and devices for imaging and treating pathologies of human organs. [0002] More specifically, the present invention relates to imaging methods and devices with high spatial and temporal resolution based on the use of synthesis methods. Temporal resolution increases as the number of firings necessary to reconstruct the image decreases. The image acquisition rate (ie, the number of images per unit of time) is directly related to this temporal resolution. Background technique [0003] Standard echographic imaging systems use echoes backscattered by the medium to be probed (typically biological tissue) to analyze changes in the acoustic impedance properties of the biological structure and thereby reconstruct an image of the medium. [0004] Ultrasound images are typically obtained by generating and transmitting beams focused at a given focal length and emitted in...
