ULTRASONIC DIAGNOSTIC APPARATUS, METHOD OF FORMING ULTRASONIC TOMOGRAPHIC IMAGE, AND PROGRAM FOR FORMING ULTRASONIC TOMOGRAPHIC IMAGE

摘要

PROBLEM TO BE SOLVED: To acquire an ultrasonic tomographic image permitting a more accurate diagnosis.;SOLUTION: This ultrasonic diagnostic apparatus 2 is provided with a frequency component adjusting section 25 adjusting spatial frequency components of original image data of the ultrasonic tomographic image. The frequency component adjusting section 25 is provided with a non-sharp image data generating circuit 30 generating non-sharp image data gradually reduced in the spatial frequency components of the original image data; a subtracting circuit 31 generating differential image data; a weighting circuit 32 multiplying the differential image data by a coefficient k to carry out weighting; an integrating circuit 33 integrating weighted differential image data to generate adjusted image data; an adding circuit 35 adding the adjusted image data and original image data to generate output image data.;COPYRIGHT: (C)2006,JPO&NCIPI
