Abstract: FIELD: medicine.SUBSTANCE: group of inventions relates namely to radiation diagnostics, and can be used to visualize the trajectory of the catheter movement. The methods, apparatus, and nonvolatile machine-readable medium implement embodiments of the present invention that include energizing a probe that is in contact with tissue in a body cavity for tissue ablation. When energized from a location transducer located in the probe, signals are received that indicate the location of the probe in the cavity. The signals are processed in such a way as to obtain points of three-dimensional coordinates of the location corresponding to the location of the probe at successive times at which the energy was applied. When energized, a three-dimensional image of the body cavity is displayed on the screen, and visual indicators are superimposed on the three-dimensional image, with the visual indicators corresponding to the points of the three-dimensional coordinates of the location at successive times. Finally, a linear path is superimposed on the 3D image connecting the coordinate points in a sequence. Additionally, weighted average values ​​for the points of the three-dimensional coordinates of the location are calculated. The bounding sphere has a surface that includes visual indicators. Moreover, displaying the bounding sphere includes placing the bounding sphere at the center in the graphical representation of the location on the 3D image corresponding to the weighted average value for the points of the 3D coordinates of the location.EFFECT: method provides real-time feedback on the effectiveness of the performed medical procedure by visualizing the trajectory.22 cl, 5 dwg

Abstract: FIELD: metal pressure treatment.   
     SUBSTANCE: invention relates to metal pressure treatment. The method for predicting the destruction of workpieces in metal pressure treatment processes is based on the use of computer modeling in the computing environment of finite element analysis and experimental evaluation. Computer modeling of the investigated process of metal pressure treatment is carried out. A trajectory is constructed for the investigated point of the workpiece according to the results. The trajectory is constructed based on the coordinates "accumulated deformation - coefficient of stiffness of the stress state". Standard tests of specimens from the material of a deformable workpiece are carried out in the process under study, at the end of which the values ​​of accumulated deformation at the moment of destruction are determined. Two or three points corresponding to the results of standard tests are plotted in the same coordinates on the basis of which the trajectory was built. They are plotted along the abscissa 1 for tension, 0 for torsion, -1 for compression. The ordinate represents the accumulated strain values ​​determined from the results of the corresponding standard tests. A line is drawn through the found points. A line of ultimate plasticity is obtained.  
     EFFECT: as a result, it is possible to determine the areas in the volume of the deformed workpiece, which are either most prone to destruction, or in which destruction will occur.
