In the evaluation of the lung status during pulmonary embolism and patient's follow up, accurate volume estimation is important In this study a method for lungs' volume determination by SPECT images and the definition of an index of perfusion scans homogeneity (LPI) are demonstrated. From lung perfusion SPECT data of 42 patients, volumes of reconstructed transverse slices were estimated by counting...
This study demonstrates a method of determination of thyroid glandpsilas volume by use of SPECT gamma camera data, in order to calculate thyroidpsilas mass useful in Nuclear medicine therapy. The method consists of the determination of the borders of the gland from a set of transaxial tomographic images by use of a specific for each case threshold value. We have measured the thyroid volume of 48 hyperthyroid...
