The severity of fat in ultrasonic liver images is quantified based on characteristics of three regions in the image namely diaphragm, periportal veins and texture of liver parenchyma. The characteristics of these regions vary with the severity of fat in the liver, and is subjected to low signal to noise ratio, low contrast, poorly defined organ boundaries, etc., hence locating these regions in ultrasound images is challenging task for the sonographers. Automated detection of these regions will help the sonographers to do accurate diagnosis in shorter time, and also acts as a fundamental step to develop automated diagnostic algorithms. In this paper, we propose a novel multi-modal framework for detecting diaphragm, periportal veins and texture of liver parenchyma in ultrasonic liver ultrasound images. Since the characteristics of these regions differ from each other, we propose a specific algorithm for detecting each region. Diaphragm and periportal veins are detected with the combination of Viola Jones and GIST descriptor based classifier, while homogeneous texture regions are detected with the combination of histogram features based classifier and connected components algorithm. The proposed algorithm when tested on 180 ultrasound liver images, detected the diaphragm, periportal veins and texture regions with an accuracy of 97%, 91% and 100% respectively.

40 boys and 40 girls of normal height weight aged between 11 to 18 years were selected and studied radio logically, elbow joint (AP and Lat view). Appearance of trochlea in 11 year in female. Fusion of trochlea was 12 to 14 year in females and 14 to 15 year in males. Appearance of Lat. Epicondyle in males was 11 to 12 years and females 11 years. Fusion of Lat. Epicondyle was 13 to 16 year in males and 13 to 14 year in females. Fusion of med. Epicondyle in males was 14 to 16 years and females 11 to 15 years. Fusion of head of radius in male was 14 to 16 years. And in females 11 to 13 years. Appearance of olecranon process in males was 11 to 13 year and female 11 year. Fusion of olecranon process in males 17 to 18 and in females 15 to 16 years. This radiological study has medico legal and archeological importance. More over it has orthopedic and radiological importance also because inexperienced radiologist or orthopedician may think these epiphyseal lines and non-fusion secondary centers as fractures. As they belong to Maharashtra population this study has ethnic importance also. This study of estimation of age can contribute to the factors of determination of age, but cannot be the paramount conclusive (1)

Pathology changes the consistency of the tissues.To prospectively assess the accuracy of per-abdominal US elastography in the form of acoustic radiation force impulse--virtual touch tissue quantification (ARFI-VTQ) and eSie touch elasticity imaging in characterizing and differentiating inflammatory pancreatic diseases.One-hundred and 66 patients from among the patients that visited the Asian Institute of Gastroenterology, Hyderabad, India, during the period April 2009 to December 2010, for master health check-up, blood donation and those with pancreatic pathology.Based on the clinical symptomatic criteria and diagnostic imaging findings, the patients were divided into normal, chronic and acute, or acute resolving, pancreatitis group.The ultrasound based ARFI-VTQ and eSie touch elasticity imaging techniques were applied.Prospective single-center study.The mean ARFI-VTQ values were 1.28 m/s, 1.25 m/s and 3.28 m/s for the normal, chronic and acute pancreas, respectively. The eSie touch gray scale and color elastograms were light gray and purple-greenish, respectively for both normal and chronic pancreas, while for acute pancreas the elastograms were dark black on the gray scale and orange to red on color scale.Both the ARFI-VTQ and eSie touch elasticity imaging techniques may be successfully adopted in order to diagnose acute pancreatitis, to assess extent of inflammation (whether focal or diffuse), to assess peripancreatic edema, to identify presence of necrotic areas and early pseudocyst formation, to early diagnose acute recurrent attacks and to monitor patient's response to treatment.
