Curing Cancer Through Metrology

Abstract

ECM Global Measurements Solutions, provider of quality dimensional metrology and engineering support services, is working with ProTom International, developer and manufacturer of medical technology, to install a state-of-the-art proton therapy treatment center in Flint, MI, for McLaren Healthcare. This is the first in a series of proton therapy centers to be built by ProTom around the world for treating cancer patients. ECM, recognized as a world leader in high-accuracy alignment, was contracted by ProTom to align the key components of the proton therapy center under construction in Flint. The services ECM provided to ProTom were supported by ECM’s use of portable measurement equipment, including laser trackers, digital levels, and laser scanners, as well sophisticated measurement and analysis software. ECM worked closely with ProTom personnel to design and implement an inspection and alignment plan, meeting ProTom’s exact requirements and aggressive installation schedule for the Flint facility. The initial alignment task required ECM to measure the as-built structure of the concrete building in Flint, and identify the best alignment in three dimensions for the path of the proton beam. The measurements of the building were performed using a total station and a laser tracker to establish the optimum location for the proton accelerator, switchyard magnets, three 50-ton gantries, patient treatment rooms, and the control network, which is used to relate all the key components into one global reference system.
