A modern CAD (computer-aided diagnosis) system development involves a multidisciplinary team whose members are experts in medical and technical fields. This study indicates the activities of medical experts at various stages of the CAD design, testing, and implementation. Those stages include a medical analysis of the diagnostic problem, data collection,(More)
This paper presents a 3D image processing method that is based on the analysis of Hessian matrix eigenvalues combined with a multiscale image analysis approach. The method, originally developed for blood vessels detection in medical images, can also be used in other areas, where finding line-like structures in the image is required. Theoretical background,(More)

This paper presents an automatic method for image contrast enhancement necessary as a preprocessing step during vasculature detection in medical images. The method takes as input two volumetric images: one containing the original data from a computed tomography (CT) study and the other one containing segmented liver as a binary mask. The aim of the method(More)
In this paper a novel multi-stage automatic method for brain tumour detection and neovasculature assessment is presented. First, the brain symmetry is exploited to register the magnetic resonance (MR) series analysed. Then, the intracranial structures are found and the region of interest (ROI) is constrained within them to tumour and peritumoural areas(More)
This paper presents a study aimed to assess applicability of artificial neural networks (ANNs) in human activity recognition from simple features derived from accelerometric signals. Secondary goal was to select the most descriptive signal features and sensor locations to be used as inputs to ANNs. Five triaxial accelerometers were attached to human body in(More)
Defined tissue defects were made in the tibiae of 24 sheep. In each animal three defects were set; one of these was completely filled with cancellous bone and the other one with ground compact bone, whereas the third one was not grafted and served as control. During the first 3 weeks no significant difference was seen in the formation of new bone at any of(More)
The paper presents an automatic method for liver vasculature segmentation in volumetric images obtained during Computed Tomography (CT) patient examination. The method, apart from the CT image, also requires an additional image containing binary liver mask. A modified multiscale vesselness filter (VF) performs vasculature detection. VF response is used to(More)
