Real-Time Intra-Fraction Motion Management During Radiation Therapy
There are no codes specific to the Beacon transponders. The implantation of the transponders can be coded using CPT codes, such as 32553, 49411, and 55876, based on the anatomical location. Code C9728 (Placement of interstitial device(s) for radiation therapy/surgery guidance (e.g., fiducial markers, dosimeter), for other than the following sites (any approach): abdomen, pelvis, prostate, retro...
متن کاملReal-Time Intra-Fraction Motion Management during Radiation Therapy - 6/15
Real-time intra-fraction target tracking is a technique that enables adjustment of the target radiation while it is being delivered (i.e., intra-fraction adjustments) to compensate for movement of the organ inside the body. Real-time tracking, which may or may not use radiographic images, is one of many techniques referred to as “image-guided radiotherapy” (IGRT). For this policy, realtime trac...
متن کاملReal-time prostate motion assessment: image-guidance and the temporal dependence of intra-fraction motion
BACKGROUND The rapid adoption of image-guidance in prostate intensity-modulated radiotherapy (IMRT) results in longer treatment times, which may result in larger intrafraction motion, thereby negating the advantage of image-guidance. This study aims to qualify and quantify the contribution of image-guidance to the temporal dependence of intrafraction motion during prostate IMRT. METHODS One-h...
متن کاملQuantitative assessment of the inter- and intra-muscle fat fraction variability in Duchenne muscular dystrophy patients
Introduction: Duchenne muscular dystrophy (DMD) is an X-linked recessive disease characterized by progressive muscle weakness. In young patients the weakness predominates in the pelvic girdle and upper leg and eventually becomes more generalized leading to wheelchair dependence in patients’ early teens and death in their late twenties. Regular T1-weighted MR imaging of the muscles shows increas...
متن کاملCalculation of Inter- and Intra-Fraction Motion Errors at External Radiotherapy Using a Markerless Strategy Based on Image Registration Combined with Correlation Model
Introduction: A new method based on image registration technique and an intelligent correlation model to calculate. The present study aimed to propose inter- and intra-fraction motion errors in order to address the limitations of conventional Patient positioning methods. Material and Methods: The configuration of the markerless method wa...
