Tungsten Directional Collimator

Collimators are fabricated using the above tungsten alloy and 304 stainless steel material as cladding. The tungsten alloy shield for the tungsten directional collimator is designed to provide a 50 degree radiation beam and is encased with stainless steel and totally sealed by argon arc welding.

When an exposure is taken with tungsten directional collimator attached to the exposure head of the guide tube of gamma camera, the radiation beam coming out will have a 50 degree solid angle in the forward direction. The primary radiation beam intensity in all other area except the front side will be reduced to 5% with the collimator.

At a source to film distance (SFD) of 50 cm, the beam will cover an area of a circle with 24 cm radius which is sufficient to cover a film size of 37 cm x 30 cm. Overall size : 44 mm dia x 82 mm long. Weight : 1.15kg.
