FIG. 1.

The reference system used is represented, and a field is illustrated with the collimator, gantry, and couch angles all set to 0° according to the International Electrotechnical Commission (IEC) definition. is the focus; is the field aperture; is the unitary vector normal to the field side; and are the couch longitudinal and couch rotations axes, respectively.

TABLE I.

Results for the matching between two oblique fields with the two methods presented. In column “Fixed field sizes” the collimator, couch, and isocenter coordinate are computed using Eqs. (8), (9), and (18). In column “Fixed isocenters” the collimator, couch, and jaw aperture are computed using Eqs. (11), (16), and (10). The computed quantities are signaled in bold face.
