This paper addresses the localization of anatomical structures in medical images by a Generalized Hough Transform (GHT). As localization is often a pre-requisite for subsequent model-based segmentation, it is important to assess whether or not the GH

Automatic and robust identification and segmentation of the three fissures separating the five lung lobes is a crucial building block for automated segmentation of the lung lobes and enabling pulmonary CAD applications such as automated volumetry of

Visual detection of lung nodules in multi-slice computed tomography (MSCT) datasets is a tedious, time-consuming and error-prone procedure. For this reason, various computer assisted detection (CAD) systems for the automated detection of lung nodules

Asthma, bronchiectasis, emphysema, and other pulmonary diseases are often correlated with the clinical parameters of bronchial lumen, wall thickness, and the ratio of inner bronchial to accompanying arterial diameter. Measurement of these clinical pa

Consistent volume measurement of pulmonary nodules is essential for follow-up monitoring for diagnosis and therapy purposes. Automated segmentation algorithms have to cope in a robust manner with nodules which are attached to surrounding vessels, the

With the recent introduction of combined Magnetic Resonance Imaging (MRI) / Positron Emission Tomography (PET) systems, the generation of attenuation maps for PET based on MR images gained substantial attention. One approach for this problem is the s

Recently introduced combined PET/MR scanners need to handle the specific problem that a limited MR field of view sometimes truncates armor body contours, which prevents an accurate calculation of PET attenuation correction maps. Such maps of attenuat

A pulmonary ventilation imaging technique based on four-dimensional (4D) computed tomography (CT) has advantages over existing techniques. However, physiologically accurate 4D-CT ventilation imaging has not been achieved in patients. The purpose of t
