It is estimated that a quarter of a million people in the USA are living with kidney cancer. In clinical practice, the response to treatment is monitored by manual measurements of tumor size, which are time consuming and show high intra- and inter-operator variability. We propose a computer-assisted radiology tool to assess renal tumors in contrast-enhanced CT for the management of tumor diagnoses...
Several image metrics have been proposed for pulmonary assessment via thoracic high-resolution computed tomography (HRCT) for various pathologies. This paper describes a systematic analysis of several such metrics for differentiating between interstitial lung disease (ILD) and chronic obstructive pulmonary disease (COPD). HRCT inspiratory and expiratory images for 14 patients with ILD and 11 patients...
A crucial pretreatment of computing the volume of pleural effusion is to segment and extract the effusion efficiently; cubic Hermite curve fitting and bounding box technology are proposed here. The boundary points will be identified automatically as long as the central column of image is given, the tangents of boundary points are estimated by Bessel method and the curve is sure to possess the feature...
Neurological PET/CT examinations are often performed with electroencephalogram (EEG) monitoring for epilepsy patients. However, the EEG electrodes cause metal artifacts in the reconstructed CT images which might propagate through the attenuation map into the PET reconstructions. In this study, the impact of the electrodes on the visual quality and quantification of brain PET images was investigated...
