Patent ID: 8585599

Claim:
A method implemented by an image quality improving hardware processor, the method for improving an image from an ultrasonographic device and comprising: figuring out, with the image quality improving hardware processor, a resolution coefficient of a generated image in each position from ultrasounds detected via an ultrasound probe of an ultrasonogaraphic device, by multi-level resolving to a plurality of resolutions, to obtain resolution coefficients for the plurality of resolutions, respectively; estimating via calculation, with the image quality improving hardware processor, a noise amount for each resolution of the plurality of resolutions, on a basis of the resolution coefficients obtained from the figuring; correcting, with the image quality improving hardware processor, the estimated noise amount for one or more resolution on a basis of a reliability of the estimated noise amount for the one or more resolution, where the reliability is calculated from one or more estimated noise amounts or resolution coefficients or a predetermined value; converting, with the image quality improving hardware processor, the intensity of each of the resolution coefficients figured out, the converting using information on the corrected noise amount obtained from the correcting; and reconstructing, with the image quality improving hardware processor, an image by undergoing reconstruction processing to each of the resolution coefficients having undergone the intensity conversion from the converting.
