ELECTROMAGNETIC APPLICATOR LOCALISATION FOR HIGH-DOSE-RATE BRACHYTHERAPY

摘要

FIELD: medicine.;SUBSTANCE: invention refers to medical equipment, namely to localisation facilities for therapeutic sources. The device comprises an applicator implanted into a target area and having at least one guide passage for a radiation source or seed, a number of image-visible support points comprising a number of electromagnetic sensors with the support points being attached to a patient's body and adjoining the target area; what is also provided is an electromagnetic tracking system for localising the electromagnetic sensors on the support points; the device is equipped with a processor to form a brachytherapy session program on the basis of a combination of a relative position of the electromagnetic sensors on the applicator and the electromagnetic sensors on the support points, and images are also presented. According to the second version, the device also comprises a field generator with a number of the electromagnetic sensors for position indication signalling responding to the field generator. One of the electromagnetic sensors is placed on the applicator, and another one - on the target. The device comprises a number of processors for localising the source and target in response to the signals of the electromagnetic sensors.;EFFECT: using the invention enables more accurate planning with reduced radiation load.;14 cl, 3 dwg
