An Application of PC-Based Digital Image Processing in Computer Assisted Radiology
1991The poster gives an overview of the theoretical and simulation research carried out by the Image Processing Department at IMS during the recent 5 years. The results achieved include the following topics: image reconstruction from projections (optimal parameters of the Direct Fourier Method, noise suppression and its relation to image object detection),

Computer-Assisted System for Hypertensive Risk Determination through Fundus Image Processing
2014From a fundus image, the system proposed in this paper automatically detects retinal vessels and measures some geometrical properties on them such as diameter and bifurcation angles. Its goal is to establish objective relations between different vessels, thus being able to determine cardiovascular risk or other diseases, as well as to monitor their ...

<title>Computer-assisted image processing for lung cancer localization</title>
SPIE Proceedings, 1996Autofluorescence of the tumor and surrounding tissue is the largest background source in fluorescence diagnosis. A new system which applied computer image processing technique to lung cancer localization by laser fluorescence bronchoscopy has been developed to subtract the autofluorescence background.

Computer assisted methods for the detection of pulmonary nodules have become more important as the resolution of CT scanners has increased and as more accurate and reproducible detections are needed. In this paper we describe the results of a CAD system for the detection of lung nodules and compare them against the interpretations of three independent ...

Axon sprouting typically occurs in a brain region that has been partially denervated. The present study demonstrates, quantitatively, evidence for sprouting outside the region of deafferentation. A modification of the Timm sulfide silver histochemical method was used to monitor an increase in the mossy fiber terminal field in the fascia dentata of ...

Computer assisted technology for medical image processing is developed to increase the accuracy and reliability of peripheral lung cancer diagnosis at the early stage of disease. Technology is based on optimal filtering methods that are to emphasize diagnostically important patterns and parts in lung tomograms.

The paper presents an approach for computer-assisted diagnosis of some diseases (e.g. anaemia, malaria), which are caused by deformations of erythrocyte shapes. In the method firstly the thresholding of the input MGG image is performed, using modified thresholding based on fuzzy measures. Secondly, every cell is localised and extracted.
