Patent ID: 7175598

Claim:
An ultrasound diagnosis apparatus, comprising an insonifier configured to insonify an ultrasound to a specimen; a receiver configured to receive an echo signal from the specimen resulting from the ultrasound; and a processor in communication with the receiver, the processor being configured to process the echo signal so as to obtain a first series of images under a first condition and a second series of images under a second condition, the processor further being configured to measure a first physical value on the first series of images and a second physical value on the second series of images, and the processor further being configured to adjust a time phase of the second series of images relative to a time phase of the first series of images based on the first physical value and the second physical value, wherein the processor is further configured to determine a number (N 1 ) of images in the first series of images that are included in a first predetermined period, determine a number (N 2 ) of images in the second series of images that are included in a second predetermined period, wherein a first image interval time (T 1 ) is a time between each of the first series of images, and a second image interval time (T 2 ) is a time between each of the second series of images, said interval time T 1 and said interval time T 2 are based on the first physical value and the second physical value, respectively, and wherein the processor is further configured to calculate a coefficient (C) represented in a formula: C=(N 2 ×T 2 )/(N 1 ×T 1 ), and adjust the time phase of the second series of images relative to the first series of images based on the coefficient C.
