REGULATION OF MOBILE X-RAY UNIT POSITION Russian patent published in 2011 - IPC A61B6/00 G05B19/402 

FIELD: medicine.

SUBSTANCE: invention relates to medical equipment, namely to mobile systems of obtaining images. Device for detecting error of positioning between the first and the second element contains unit of electromagnetic waves radiation, made with possibility of fixed connection with the first element, and unit of their reception and digital processing, made with possibility of connection to the second element. The second unit interacts with unit of electromagnetic waves radiation for detecting error of positioning of the first element with respect to the second element. Radiation unit contains N electromagnetic radiators located in one plane, where N is number which is larger or equals 3, and control unit made with possibility of supply, for each of N electromagnetic radiations, of corresponding electromagnetic signal, said electromagnetic signal corresponds to directed electromagnetic field, modulated by raster with binary representation, determined for said radiator, and allows unit of electromagnetic waves reception to identify by signal processing electromagnetic signals coming from respectively each of electromagnetic radiators. Device for detection is includes into mobile unit for obtaining images. In accordance with the first version of implementation radiation unit is connected to radiation source, and reception unit - to image sensor. In the second version radiation unit is connected to image sensor, and reception unit - to source of radiation.

EFFECT: application of invention makes it possible to realise asynchronous work between radiation unit and reception unit in order to simplify work with device.
