FIELD: medicine.
SUBSTANCE: group of inventions relates to interventional means for introduction into an object. System comprises an introduction element to be introduced into an object, a moving unit for moving the introduction element in the object, a tracking image generating unit for generating tracking images of the introduction element (4) within the object, wherein the tracking image generating unit comprises a radiation source for emitting a radiation beam for traversing the object, a radiation detector for detecting the radiation beam after having traversed the object and a controller for controlling the tracking image generating unit, wherein the moving unit is adapted to provide movement parameters, which define a movement of the introduction element within the object, to the tracking image generating unit and wherein the controller is adapted to control the tracking image generating unit depending on the provided movement parameters such that the radiation beam traverses a region of the object that includes the introduction element. Interventional system controller is adapted to control the radiation beam emitted by the radiation source of the tracking image generating unit, depending on the movement parameters provided by the moving unit. Interventional method and a method for controlling the tracking image generating unit are implemented by the system. In this case, computer-readable media are used for the interventional method and for controlling the image generating unit.
EFFECT: use of inventions makes it possible to reduce radiation dose when generating images.
