Contrast resolution and detail resolution are two important parameters in ultrasound imaging. This paper presents a new method to enhance these parameters, simultaneously. A parallel auxiliary beamformer has been employed whose weightings are such that an estimation of the leaked signal through the main beamformer is obtained. Then the output of main beamformer is modified according to the ...

hepatitis c virus (hcv) is a major global health problem and one of the most common causes of chronic liver diseases. the current study was carried out to investigate the ability of high resolution melting (hrm) method in hcv genotyping. 40 hcv-positive sera with unknown and 12 sera with known hcv genotypes were collected from different clinical laboratories in tehran as well as rasht in north ...

OVERVIEW: Ultrasound diagnostic scanners have gained broad acceptance in a wide range of diagnostic fields because they are able to make observations inside the body safely and in real time. In keeping with the developments in signal processing technology and semiconductor technologies, resolution and other functions were dramatically improved through the use of digital ultrasound scanners deve...
