Employ of a New Device for Intra-Operative Radiotherapy of Intracranial Tumours

摘要

This paper presents the operating experience acquired during 18 months of use of the Photon Radiosurgery System manufactured by Photo-electron Corp. as an intra-operative radiation therapy device. The device is based on a miniature x-ray source that delivers low energy x-rays from the tip of a 3.2 mm thick needle-like probe. The interstitial stereotactic employ of the source has already been reported, while there is no evidence of the open-field intra-operative use in the literature.
