This percision quality tool, is ideal for daily, weekly or monthly quality control assessments of all mechanical and geometrical treatment parameters of linear accelerators or teletherapy units.
The Precision Isocentric Beam Checker, IBC II, consists of a large opaque acrylic screen backed by a secondary plate, both supported by two lateral uprights. The screen is inscribed with lines precisely defining corners, edges and center of the screen’s 10 x 10 cm and 20 x 20 cm fields. Intersecting center lines are inscribed with short lines spaced 1 cm apart. The screen can rotate about its axis in increments of 45o. Tungsten markers of 2 mm diameter are embedded in the center and corners of the fields.
A l0” x 12” ready-pack film can be sandwiched between the two plates. When exposed, the tungsten markers project a sharp image on the film. The necessity of pricking holes into the film is therefore eliminated.
The device's acrylic base-plate has an attached bubble level and non-slip leveling legs that allow it to be quickly and conveniently set up for use.
