FIELD: medicine.
SUBSTANCE: invention relates to devices and methods of determining a position of an object, placed in a living organism. A method of visualisation includes reception of an inlet signal, indicating correspondent visual coordinates of a multitude of points, located along the length of a probe inside a subject's body, and application of the model of the known mechanical properties of the probe to the visual coordinates in order to calculate an assessment function relative to shapes, which can be taken by the probe in the body. A shape is selected in accordance with the assessment function, with corrected coordinates of the points along the probe length being generated of the basis of the shape. After that, the probe image with application of the corrected coordinates is displayed. The device includes interface, receiving signals, pointing to the visual coordinates of the multitude of sensors, located along the probe inside the subject's body, and a processor, performing stages of the visualisation method.
EFFECT: application of the invention provides more accurate visualisation of the flexible probe in the subject's body.
