Ultrasonic diagnosis apparatus and program

摘要

According to one embodiment, an ultrasonic diagnosis apparatus is configured as follows. Namely, the apparatus includes a first unit configured to generate a first transmission wave for acquisition of a first image with a higher priority on sensitivity than on resolution, a second unit configured to generate a second transmission wave for acquisition of a second image with a higher priority on resolution than on sensitivity, an analysis unit configured to perform multiresolution analysis based on predetermined transform processing on the first image and the second image, a filter unit configured to perform predetermined filter operation for corresponding coefficients of the first image and the second image for each coefficient of each resolution acquired by the analysis unit, and an inverse transform unit configured to generate a composite image of the first image and the second image by performing inverse transform processing of transform processing by the analysis unit.

1. An ultrasonic diagnosis apparatus which acquires tomographic image data by scanning a predetermined region of an object with an ultrasonic wave, the apparatus comprising:
an ultrasonic probe configured to transmit first transmission waves having different amplitudes and second transmission waves having different phases for each of scanning lines, and to receive first echoes caused by the first transmission waves and second echoes caused by the second transmission waves; an image generation unit configured to generate, without use of a Doppler method, a first image based on the first echoes and a second image based on the second echoes, wherein a spatial resolution of the first image is higher than a spatial resolution of the second image and a sensitivity of the second image is higher than a sensitivity of the first image; a multiresolution analysis unit configured to perform multiresolution analysis based on predetermined transform processing on the first image and the second image; a filter operation unit configured to perform a predetermined filter operation for corresponding coefficients of the first image and the second image for each coefficient of each spatial resolution acquired by the multiresolution analysis unit by the predetermined transform processing; and an inverse transform unit configured to generate a composite image of the first image and the second image by performing inverse transform processing of the transform processing by the multiresolution analysis unit for an operation result obtained by the filter operation unit.
