Abstract：Stereotactic body radiation therapy (SBRT) derives naturally from stereotactic radiosurgery (SRS) technology and clinical application. Under very precise image guidance, SBRT delivers a very large dose to a well-defined target in a small number of fractions. Body gamma knife is an innovative radiotherapy device that was independently conceptualized and designed in China, which extends Gamma-beam therapy from head to body. For nearly fifteen years of technology development and clinical practice, body gamma knife has been following the traditional body frame positioning mode, whose lack of position precision prevents the knife’s widespread application as a SBRT equipment. However, in recent years, image guidance technique begins to be applied in body gamma knife, which would initiate a new phase for its standard SBRT practice. This paper mainly introduces the principles, methods, experiments and preliminary results of an image-guided positioning system used in Body Gamma Knife.
