In this paper, two new geodesic distance transforms for gray-scale images are presented. The first transform, the Distance Transform on Curved Space (DTOCS), performs the calculation with integer numbers. The second transform, the Weighted Distance Transform on Curved Space (WDTOCS), gives a weighted distance map with real numbers for an arbitrary gray-value image. Both transforms give a distan...
Grey scale and power Doppler sonography play an important role in assessment of cervical lymphadenopathy. However, before examination of pathological nodes, a clear understanding of the anatomy of cervical nodes, scanning technique and sonographic appearances of normal cervical nodes is essential. This article reviews these topics in order to provide a baseline for sonographic examination of ce...
INTRODUCTION The optic nerve sheath diameter (ONSD) may be increased in brain-injured patients, especially children, with intracranial hypertension. We investigated whether measurements of ONSD correlated with simultaneous noninvasive and invasive measurements of the intracranial pressure (ICP) in brain-injured adults. METHODS Seventy-six critical care patients (58 males; 47 +/- 18 years old)...
