FIELD: medicine.SUBSTANCE: invention relates to means of measuring body volume in the process of ultrasound visualisation. Method of automatic composition of volume in system of ultrasound visualisation contains stages, at which set of data of 3-dimensional object image is collected; user selects first surface of interest in the data of 3-dimensional image, with said first surface containing first cut of object; main axis of first cut on first surface of interest is automatically determined, first set of planes from the data of 3-dimensional image is specified, with said planes not being parallel to main axis of first cut, however being parallel to each other with specified distance between two successive planes along main axis; contour of each second cut is automatically drawn for, at least, two planes from first set of planes, each of which contains respective second cut of object; automatic composition of object volume is carried out by superposition of contours drawn in two planes from first set of planes along main axis and by placement of planes at specified distance. Method of calculating volume in ultrasound system includes composition of object volume, with each plane from set of planes being perpendicular to main axis of first cut, after which partial volumes, contained between two successive planes in set of planes on main axis of first cut are calculated and summed up. Device for method realisation contains means for collecting set of the data of 3-dimensional image by means of ultrasound, means of displaying, at least, image of first cut of object, means of selection by user of first surface of interest in the data of 3-dimensional image, means for determination of main axis of first cut of object on surface of interest, means of specifying first set of planes from the data of 3-dimensional image, means of drawing in, at least, two planes from first set of planes, each of which contains respective second cut of object, contour of each second cut, and means of object volume composition. Composition of device also includes computer-readable carriers, whose software contains commands for realisation of methods.EFFECT: application of invention makes it possible to increase accuracy of volume determination and reduce human interference in the process of measurement.15 cl, 6 dwg |
