• Radiation and light-field congruence

• Collimator isocentricity

• Collimator field size accuracy

• Compact and easy to carry

• Laser alignments

• No assembly required

• Gantry isocentricity

• Rugged construction

The Isocentric Beam Checker consists of stainless steel base containing three adjustable rubber-tipped legs and built-in bubble level.  Attached to the base is a translucent screen plate which can be rotated 360° in 15° steps.  Inscribed on the plate are 3 field sizes; 2 mm x 2 mm, 5 cm x 5 cm and 10 cm x 10 cm.  The field sizes are outlined with parallel and diagonal lines.  The center of the field and all corners are provided with tungsten markers to project a sharp image of the field on verification films.
