The Mobius AIRO mobile CT for image‐guided proton therapy: Characterization & commissioning

PURPOSE The purpose of this study was to characterize the Mobius AIRO Mobile CT System for localization and image-guided proton therapy. This is the first known application of the AIRO for proton therapy. METHODS Five CT images of a Catphan® 504 phantom were acquired on the AIRO Mobile CT System, Varian EDGE radiosurgery system cone beam CT (CBCT), Philips Brilliance Big Bore 16 slice CT simu...

Development of Technology for Image-Guided Proton Therapy

Strategies for Image-guided Proton Therapy of Cancer

During the past half century, an ongoing technological revolution in cancer imaging and radiation treatment has taken us ever closer to the goal of treating localized tumors without harming normal tissues. In his visionary 1946 paper, Harvard physicist Robert Wilson suggested that energetic protons could provide a nearly ideal form of radiotherapy. What makes protons the preferred particle type...

Commissioning experience with cone‐beam computed tomography for image‐guided radiation therapy

This paper reports on the commissioning of an Elekta cone-beam computed tomography (CT) system at one of the first U.S. sites to install a "regular," off-the-shelf Elekta Synergy (Elekta, Stockholm, Sweden) accelerator system. We present the quality assurance (QA) procedure as a guide for other users. The commissioning had six elements: (1) system safety, (2) geometric accuracy (agreement of me...

CT-Image Guided Brachytherapy

The name “Brachytherapy” is derived from ancient Greek words for short distance (brachios) and treatment (therapy) and refers to the therapeutic use of encapsulated radionuclides placed within or close to the tumor. Brachytherapy (BT), used as an integral part of cancer treatment for almost a century, developed in last three decades a rapid growth with the development of afterloading devices an...
