ELASTIC IMAGE FORMING METHOD THROUGH STRAIN NORMALIZATION AND AN ULTRASOUND SYSTEM FOR THE SAME, CAPABLE OF TRACKING A PATIENT'S LESION PROGRESSING

摘要

PURPOSE: An elastic image forming method through strain normalization and an ultrasound system for the same are provided to diagnoses a patient after checking the development of lesion by implementing ultrasonic wave elasticity image as a change rate on an average strain.;CONSTITUTION: Frame data is inputted respectively when stress is applied and not applied(301). Displacement among frame data is calculated(302). Strain is calculated using the displacement(303). Normalization standard value is obtained in the each strain which is calculated. The elasticity image is formed using the normalization standard value(305). The normalization standard value is the whole average value of each strain.;COPYRIGHT KIPO 2010
