Some say that the best industrial design is invisible, and if you notice it, something’s wrong. That’s seems especially true with medical devices, which most people only encounter when… well, something’s wrong. So when med-tech firm Varian wanted to redesign their line of nuclear medicine devices (which are used to scan for scary stuff like malignant tumors), they brought in the big guns at BMW DesignworksUSA. The result of their collaboration, the Varian TrueBeam, may not look much different at first glance from any other hulking piece of hospital equipment. But as with any effective industrial design, it’s the details that matter most.
