    ABSTRACT: Technetium scan images of bone for 10 patients are analysed. The images are taken wherein both the healthy bone and its corresponding other contiguous bone are taken together to study the abnormalities present within a bone, which are complements of each other. The Siemen's gamma camera scans the skeletal parts after injecting the Technetium-99 <sup>m</sup> methylene diphosphonate isotope intravenously. Bone-scan images are available in X-ray radiograph mode only and they do not provide the relevant software for image analysis and interpretation as a public domain material. An attempt is made to develop the requisite software for image analysis and interpretation of bone scan images. This is being done to the provide an advisory system and to help in the diagnosis of bone disorders by nuclear medical specialists. The X-ray radiographs are digitized by using a Pullinix camera. Digitization is helpful in segmentation, to draw the profiles in horizontal and in vertical forms of the image, and for the study of local variability of the absorption of technetium in the bone. For this purpose, the software developed in the PC environment is less costly and can be made available in a number of diagnostic centres

    ABSTRACT: Thallium-201 myocardial stress imaging (TSMI) has high specificity for coronary artery disease. Segmental analysis of the stress thallium scintigraphic information about the regions at highest risk of ischemia, though all the vessels with significant stenoses may not be identified. Abnormal studies are uncommon in patients without significant narrowings, while regional abnormalities are rare except in the distribution of the stenosed vessels. Tomographic approaches to TSMI have improved the diagnostic accuracy. The textural analysis has to find the global variance of the left ventricle and harmonic analysis has to define the variability in terms of several sin and cos terms by using Fourier analysis. The textural and harmonic analysis act as advisor system to a doctor, so that a nuclear medical specialist can have a confirmatory analysis system to suit their own evaluation procedures. The camera scans the myocardium both in static and dynamic conditions. The software is a in-built part of the system

    ABSTRACT: The authors propose a new concept known as neighbourhood images to generate a sequence of images from dilation to erosion and from closing to that of opening on the basis of an algorithm presented by K. Vladimir (1986) in the morphologic domain. These generated images show a high correlation to each other. Basically, the morphologic procedures separate the border regions from those of the interior and as such, the image content and border component are affected in the morphologic transformation. The authors further utilised the dilated, the median and eroded images for decorrelation and generation of images which are ortho-normal to each other. Such decorrelated images can be utilised for the study of the borders separately from that of interior pixels. Based on this background, X-ray image of the neck and chest region displaying the malignancy near the neck region is studied. Neighbourhood images are selected and a set of three morphologic images are used for decorrelation. The first image shows enhancement with reduction of noise content. The second and the third image display the contours of the malignancy. X-ray images are routinely used, for the visual interpretation and analysis, and are not subject to rigorous procedures of image analysis
