The tagging of blood vessels from medical images is an essential step in the computer aided diagnosis of the vessels' diseases. Different approaches, such as the Frangi vesselness filtering, the seeded region growing, and the adaptive thresholding are tested in order to obtain the vessels mask from the X-ray cardiac angiograms. The spurs are cleaned with morphological operations and the final results...
The delineation of blood vessels on medical images is an essential step in the computer aided diagnosis of the vessels' diseases. In this paper, it will be examined four different image processing methods in order to detect the vascular map in X-ray cerebral or cardiac angiograms.
The present paper is dedicated to systemic botany and proposes a more objective morphological classification of Gentianaceae plant family into species and genera using the fractal theory. A collection of 19 Romanian species are collected from the herbarium of Botanical Garden, Cluj-Napoca. The research is conducted on the study of the three genera: Gentiana, Gentianella and Gentianopsis, which were...
This X-ray angiography is the current gold standard for morphology based diagnosis of coronary arteries due to their spatial and temporal resolution. Transit time methods are applied on coronary angiograms to estimate the interval of time required for the contrast material to traverse the distance between two regions of interest. They represent an important prerequisite for estimating blood flow parameters...
The paper describes an overview of the existing and future market for wireless remote patient monitoring applications, and presents the differences between the most well-known implementations, i.e., WMTS and WLAN. There are presented results and useful information from official reports and reliable sources, such as Frost & Sullivan and AAMI, results which revealed the clear evidence of continuing...
The progress of mathematical modeling and image processing in medicine from the last decades have had an important impact in the development of diagnosis and treatment of cardiovascular diseases using the simulations of blood flow and pressure evolution models in specific location of the heart or vessels, personalised with patient data. This method is expected to increase the efficiency and reduce...
The x-ray angiograms are frequently performed before a cerebral intervention on diseased vessels. The clinicians complain about the difficulty to find small vessels on images with grey level intensities and to differentiate veins from arteries. The main problem in classification resides in finding the right parameters which can completely characterize the patterns of pixels' intensity time course...
