FIELD: medicinal technique. SUBSTANCE: at the first stage of the suggested method one should specify location of malignant neoplasm detected as a result of previous diagnostics. For this purpose one should scan patient's body part where this neoplasm is located. Scanning is carried out by replacing area of radiation concentration created due to crossing of several roentgen bundles. Information about tissues density is obtained with the help of detectors; secondary radiation appeared in area of concentration should be transported towards them. At the second stage, one should scan with the help of the same means of roentgen bundles by replacing area of concentration within the limits of malignant neoplasm observed at the first stage. Moreover, sources of roentgen radiation should be transferred into the mode of increased intensity sufficient for radiation impact upon tissues of malignant neoplasm. For the purpose to transmit sources' radiation into area of concentration and secondary radiation to detectors one should apply different combinations of collimators, roentgen lenses and semilenses which form roentgenooptic system together with sources and detectors. At scanning area of concentration it occurs mutual replacement of roentgenooptic system as whole integrity and patient's body. Coordinate sensing devices fixing the mentioned replacement, and detectors are connected by their outputs to equipment for information processing and depicting. Application of the present principle for obtaining information on density of biological tissues and similar means for creating roentgen bundles at both stages favors increased accuracy of measurements and carrying out radiation impact and decreasing irradiation dosage in healthy tissues. The present innovation enables to increase accuracy for focusing on due to application of the same roentgen bundles both for detecting tissues structure and location of malignant focus, and for radiation impact upon the focus, as well. EFFECT: higher efficiency. 27 cl, 11 dwg
