FIELD: medicine.
SUBSTANCE: positioning device comprises a radiation source in the form of a semiconductor diode laser and a selective-spectral photosensitive digital video camera configured to be installed above the operating field, a label connected through a digital signal processing unit to a personal computer, the label being single-channel and mounted on the radiation source, five anchors are designed to be mounted on the upper and lower angle of the wound and to the right, left and below the operating field, and the single-channel label and anchors are connected to a gateway and a digital processing unit to form a navigation system SDS-TWR.
EFFECT: use of the invention will allow more accurate determination of tumour tissue boundaries.
