Rapid additive manufacturing of MR compatible multipinhole collimators with selective laser melting of tungsten powder

Abstract

Additive manufacturing is a very promising technique for the production of complex multipinhole collimators and may also be used for producing other complex collimators. The cost of this technique is only related to the amount of powder needed and the time it takes to have the collimator built. The timeframe from design to collimator production is significantly reduced.
