Ultrasonic diagnostic apparatus and image processing method
First Claim
1. An ultrasonic diagnostic apparatus comprising:
- an image data generation unit which transmits and receives an ultrasound to and from a space including a target to generate ultrasonic image data;
a target extraction unit which applies a digitizing process to the ultrasonic image data using a first threshold value to extract data corresponding to the target; and
a region-of-interest setting unit which sets a region of interest within the ultrasonic image data, wherein the target extraction unit applies a digitizing process, using a second threshold value, to the ultrasonic image data within the set region of interest.

Abstract
A three-dimensional image data memory stores three-dimensional image data including that of a imaging target. A digitization processor unit applies a digitizing process to the three-dimensional image data using a first threshold value to extract data corresponding to the target. A user sets a two-dimensional region of interest surrounding a portion in which the extraction of data using the first threshold value is inaccurate and a 3D region-of-interest generator unit generates a three-dimensional region of interest from the two-dimensional region of interest which is set. The digitization processor unit applies a digitizing process using a second threshold value to the three-dimensional image data within the three-dimensional region of interest.
