M. Bolla et al., 3-D CONFORMAL RADIOTHERAPY PROCEDURE AND REGISTRATION OF PRERADIOTHERAPEUTIC AND INTRARADIOTHERAPEUTIC DATA, Bulletin du cancer, 82, 1995, pp. 586-591
The authors describe the different steps of 3-D conformal external irr
adiation. They mention as well two procedures of isocentric reposition
ing which are mandatory for the matching of anatomical data: the first
one is acquired before the simulation and the second one first before
the radiotherapy session.
