Webreduction in ultrasound images but contain no information regarding the RF to B-mode conversion processes [6], [7]. In this paper, a method is developed to convert IQ data from the ultrasound machine to a scan-converted B-mode image. Noise reduction techniques on the resulting B-mode image will also be investigated. II.
