Generation and Analysis of Ultrasound Speckle Patterns considering Acoustic Field Characteristics of Transducer
트랜스듀서의 음장 특성을 고려한 초음파 스펙클 패턴의 발생과 해석
Abstract
In this paper, we propose a new process for ultrasonic B-mode image considering the sound field effects of a concave circuit focused transducer, and aim to remove the speckle pattern which cause the blurring on boundary in ultrasonic B-mode image. We discuss in detail the conception of speckle pattern generation, and the frequency compounding method which is applied to the process for getting a speckle reduced B-mode image. Through the computer simulation, we define the meaning of speckle region, and show the results of reduced speckle pattern. It is discovered in the results that the frequency compounding method is very effective for boundary detection and that the application of the method is limited by various conditions.
