Design principles for a collimator at 35 g

The design principles of the late Wim van der Hoek, former Philips engineer and Eindhoven professor, are still current in high-tech systems engineering, including in the field of medical technology development. They are especially useful when high precision is required and conditions are challenging. This Mikroniek article presents a brief overview of the design philosophy, illustrated by an elegant example, from Van der Hoek’s ‘own’ Philips; the design of a collimator, for a CT scanner, of which all parts are subjected to accelerations of 35 g.
