Abstract:
1. A method of controlling irradiation positioning, the method comprising: obtaining a plurality of reference scans of a target tissue, each representing a unique phase of a breathing cycle; obtaining a pre-treatment scan of the target tissue; identifying the reference scan of the obtained plurality of reference scans whose phase is consonant with the obtained pre-treatment scan; computing at least one motion vector field between the identified reference scan and another of the plurality of reference scans different from the identified reference scan; applying the at least one computed motion vector field to one of the obtained pre-treatment scan and the another of the plurality of reference scans so as to derive at least one synthetic scan whose phase is consonant with the other of the obtained pre-treatment scan and the another of the plurality of reference scans; and positioning the target tissue in relation to a therapeutic agent source responsive to said obtained at least one synthetic scan.
