As the add-on collimator works almost completely autonomously of the linear accelerator (LinAc), no modifications to the latter were necessary. The adaptations to the Moduleaf were mainly software-based. In order to reduce the complexity of the system, outdated electronic parts were replaced with newer components where practical.\u003c\/p\u003e\u003cp\u003eVerification was performed by measuring the latency of the system as well as the impact on applied dose to a predefined target volume, moving in the leaf's travel direction. Latency measurements in software were accomplished by comparing the target and current positions of the leaves. For dose measurements, a Gafchromic EBT2 film was placed beneath the target 4D phantom, in between solid water plates, and moved alongside with it.\u003c\/p\u003e\u003cp\u003eBased on the results, a tracking-capable add-on collimator seems to be a useful tool for reducing the margins for the treatment of small, slow-moving targets.\u003c\/p\u003e\u003cp\u003eRadiotherapy is one of the most important methods used for the treatment of cancer. Irradiating a moving target is also one of the most challenging tasks to accomplish in modern radiotherapy.\u003c\/p\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Andreas Böhler\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 3658106573\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9783658106577\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Springer\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 10\/09\/2015\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 53\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.22lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 8.27h x 5.83w x 0.16d","brand":"Andreas Böhler","offers":[{"title":"Paperback","offer_id":49148324020479,"sku":"9783658106577","price":54.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/www.whiterainbookhouse.com\/products\/collimator-based-tracking-with-an-add-on-andreas-bzihler-9783658106577","provider":"WR Book House","version":"1.0","type":"link"}
