It is well known that ultrasonography is a diagnostic method for visualizing inside human tissues by spreading ultrasounds and measuring their return time to the sensor. However, the interface between the human skin and this ultrasound transducer attenuates the received signal and the medical image quality deteriorates significantly. In this paper we propose a filtering technique in order to compensate this attenuation. A finite impulse response filter (FIR) based on a Delayed Least Mean Square (DLMS) was optimized

Abstract
It is well known that ultrasonography is a diagnostic method for visualizing inside human tissues by spreading ultrasounds and measuring their return time to the sensor. However, the interface between the human skin and this ultrasound transducer attenuates the received signal and the medical image quality deteriorates significantly. In this paper we propose a filtering technique in order to compensate this attenuation. A finite impulse response filter (FIR) based on a Delayed Least Mean Square (DLMS) was optimizedFile in questo prodotto:
