IsoLock shall report Sag Residual Error Score per complete isocenter test image set, a single value numerical measure representing deviation from expected isocenter sag behavior.
Sag Residual Error Score can indicate ball or couch position drift or beam steering change during image acquisition.
IsoLock shall report Skew Residual Error Score per complete isocenter test image set, a single value numerical measure representing deviation from expected isocenter skew behavior.
Skew Residual Error Score can indicate ball or couch position drift or beam steering change during image acquisition.
Sag Residual Error Score can indicate ball or couch position drift or beam steering change during image acquisition.

During machine acceptance, a Varian procedure for isocenter verification (“Isolock”) was used to evaluate the central
axis x-ray beam variation due to the gantry, couch, and collimator rotation.6 Briefly, a collimated disk fixture is affixed to
the gantry interface mount, projecting a circular field onto the
MV imager. A tungsten BB, attached to a micrometer for fine
positioning, is extended off the treatment couch and centered
within the disk aperture at gantry angles of 0◦ and 90◦. MV
images were acquired using two different preprogrammed
treatment plans: one at 63 different gantry/collimator angles
and another with 13 different couch angles. Images were analyzed with proprietary software to verify that (1) the central
axis x-ray beam variation due to the gantry and/or collimator positions was confined to a sphere of 0.5 mm radius, and
(2) the central axis x-ray beam variation due to the gantry,
couch, and/or collimator positions was confined to a sphere
of 0.75 mm radius.
