Ludlum Medical Physics Model L-051
TG-51 Linac Filter
Introduction
The primary purpose of the AAPM TG-51 dosimetry
protocol was to provide a uniform methodology for a clinical reference
dosimetry measurement. Both the photon and electron beams from accelerators
needed to be within the recommended nominal energies (Beam Quality). The
methodology included the application of a 1mm thick lead foil that is placed
just below the accelerator head, to reduce the electron contamination and
therefore help to specify the beam quality. The lead foil is typically
attached to the accelerator head or to the blocking tray using surgical
tape, wires or whatever material was available.
The Ludlum Model L-051 “TG-51 Linac Filter” has been
designed to simplify the task of making the prescribed Beam Quality
Measurements, by providing a true 1mm thick lead foil (+/-0.2mm) that has
been specially bonded to a 12” x12” polycarbon (Lexan ®) plate. The plate
has an opening cut into the center, exposing a 10cm x10cm area of the bonded
11cm x 11cm lead foil. This plate can be customized by the user to fit the
tracks of most blocking trays. The polycarbon material is easily cut with a
standard utility knife or sheers. The combination lead foil and polycarbon
plate also helps to maintain the integrity of the lead foil and also makes
it easier to handle and store the filter.
