FIELD: scanning devices.
SUBSTANCE: invention relates to the field of scanning the internal area of holes. The essence of the invention consists in that the method for measuring round holes in medium with ionizing radiation in transparent liquid additionally contains stages at which, before calibration and the beginning of measurements, waterproof sealing of a scanning device is carried out, which is immersed in external liquid medium surrounding the hole of the object, while the pressure equal to or exceeding the pressure of the external environment is maintained inside the case using injected gas or gas mixture.
EFFECT: increase in the resolution and accuracy of scanning the surface of internal areas of holes.
