Current assessment of spine growth for patients undergoing friendly surgical treatment early-onset scoliosis (EOS) is the use serial, 1-dimensional standard-of-care coronal vertical height (SoCVH) measurements. Any out plane missed by SoCVH, which may underestimate actual spine. This study set to validate novel 3-dimensional true length (3DTSL) radiographic measurement technique measuring EOS patients.3DTSL accuracy, reliability, and repeatability was assessed using 10 physical model...
The purpose of this work is to develop accurate computational methods comprehensively characterize and model the clinical ExacTrac imaging system, which used as an image guidance system for stereotactic treatment applications. Spektr toolkit was utilized simulate spectral characterization system. Since only simulates primary beam (ignoring scatter), a full also developed in Monte Carlo (MC) To ensure proper performance both simulation models, MC data were compared measured half value layers...
Physeal closure after slipped capital femoral epiphysis fixation can be difficult to assess on two-dimensional conventional radiographs. Radiostereometric analysis offers improved motion detection over radiography, whereas the EOS biplanar imager provides a means for low radiation weight-bearing images. This phantom study assessed reliability of measuring using radiostereometric in model. The accuracy and precision were better than 0.09±0.05 mm 0.20°±0.36° when centered imaging space, within...
Purpose.The purpose of this work is to quantify the dependence patient-specific imaging dose on patient-size from ExacTrac stereoscopic/monoscopic real-time tumor monitoring during lung and prostate stereotactic body radiotherapy (SBRT).Approach. Thirty 30 SBRT patients that were treated with volumetric modulated arc therapy (VMAT) selected divided into three patient size categories. Imaging doses all fractions calculated retrospectively assuming went through their actual VMAT treatment...
Background and purpose: The low radiation biplanar X-ray imager (EOS imaging, Paris, France) scans patients in a weight-bearing position, provides calibrated images, limits radiation, an asset for serial radiostereometric analysis (RSA) studies. RSA vivo precision values have not been published this type of imaging system, thus the goal study was to assess utilizing imager.Patients methods: At mean 5 years post-surgery (range 1.4–7.5 years), 15 total knee arthroplasty (TKA) participants...
