Download or read book Study of Novel Techniques for Verification Imaging and Patient Dose Reconstruction in External Beam Radiation Therapy written by Geneviève Jarry and published by . This book was released on 2006 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The scattered radiation present in kV CBCT images was evaluated using MC simulations. Simulated predictions of the scatter distribution were subtracted from CBCT projection images prior to the reconstruction to improve the reconstructed image quality. Reducing the scattered radiation was found to improve contrast and reduce shading artifacts." --
