Examination materials' microstructures using X-ray belongs to the nondestructive testing methods. This methods allows reconstructing a 3D image of the specimen, serial sections and processing it in order to visualize and measure stereological features. In paper we present the possibilities of application of computer programmes for three dimensional visualization of computed tomography d[...]

Environmental Scanning Electron Microscopy and image analysis techniques in biocompatibility investigations of hydroxyapatite of pig origin

Czytaj za darmo! »

Hydroxyapatite (HAp - Ca10(PO4)6(OH)2) is a well known biomaterial. Various HAp biomaterials (synthetic as well as of natural origin) are commercially available. HAp of pig origin is not commercially available yet. This paper describes application of Environmental Scanning Electron Microscopy (E-SEM) and image analysis techniques in vitro biocompatibility investigations of HAp of pig origin. [...]

Application of image analysis for quantification of cardiac function in vivo by MRI in the mouse model of heart failure

This paper presents the application of the image analysis method for the detection of left ventricle in the mouse hearts in vivo. Images were obtained using Magnetic Resonance Imaging (MRI) and the method of their analysis was developed. The whole process of detection was divided into two main parts: initial analysis and final analysis. The aim of the initial analysis was to establish the mar[...]
