METHOD AND APPARATUS FOR GENERATING DIAGNOSTIC IMAGE AND MEDICAL IMAGE SYSTEM
First Claim
1. A method of generating a diagnostic image with respect to a first direction and a second direction of a subject, the method comprising:
- transmitting a transmission signal in the first direction to the subject;
acquiring at least two radio frequency (RF) frames including a first RF frame and a second RF frame from an echo signal reflected from the subject;
estimating a second directional displacement indicating a degree of movement of a first point of the subject appearing in the first RF frame in a second direction in the second RF frame;
generating an ultrasonic image corresponding to the second RF frame; and
correcting an error of the generated ultrasonic image using the estimated second directional displacement.

Abstract
A method of generating a diagnostic image of a subject including transmitting a transmission signal to the subject; acquiring a first RF frame and a second RF frame from an echo signal reflected from the subject; estimating a second directional displacement indicating a degree of movement of a first point of the subject appearing in the first RF frame in the second RF frame; generating an ultrasonic image corresponding to the second RF frame; and correcting an error of the generated ultrasonic image using the estimated second directional displacement. The first point may appear in the first RF frame and the second RF frame.

11. An apparatus for generating an ultrasonic a diagnostic image with respect to a first direction and a second direction of a subject, the apparatus comprising:
-
at least one transducer to transmit a transmission signal in the first direction to the subject and receiving an echo signal reflected from the subject; a radio frequency (RF) frame acquisition unit to acquire at least two RF frames including a first RF frame and a second RF frame from the echo signal; a displacement estimation unit to estimate a second directional displacement indicating a degree of movement of a first point of the subject appearing in the first RF frame in a second direction in the second RF frame; an image generation unit to generate an ultrasonic image corresponding to the second RF frame; and an error correction unit to correct an error of the generated ultrasonic image using the estimated second directional displacement. - View Dependent Claims (12, 13, 14, 15, 16)

17. A medical image system comprising:
-
an apparatus to generate a diagnostic image by transmitting a transmission signal in a first direction to a subject, to acquire a first radio frequency (RF) frame and a second RF frame from an echo signal reflected from the subject, to estimate a directional displacement indicating a degree of movement of a first point of the subject appearing in the first RF frame in a second direction perpendicular to the first direction in the second RF frame, and to generate an error corrected ultrasonic image using the estimated directional displacement; and a display unit to display the generated error corrected ultrasonic image. - View Dependent Claims (18, 19, 20)
