The four-dimensional (4-D) eXtended CArdiac-Torso (XCAT) series of phantoms was
developed to provide accurate computerized models of the human anatomy and physiology …

In radiation-based medical imaging research, computational modeling methods are used to
design and validate imaging systems and post-processing algorithms. Monte Carlo methods …

Background Daily image-guided radiotherapy (IGRT) can contribute to cover extended body
volumes with low radiation dose. The effect of additional imaging dose on secondary cancer …

Abstract Purpose Cone beam CT (CBCT) is used in paediatric image-guided radiotherapy
(IGRT) for patient setup and internal anatomy assessment. Adult CBCT protocols lead to …

In this work, we propose a robust offline geometry calibration method for an offset-detector-
based dental cone-beam computed tomography (CBCT) system. Although a host of …

This study was conducted to estimate the organ equivalent dose and effective imaging dose
for four‐dimensional cone‐beam computed tomography (4D‐CBCT) using a Monte Carlo …

Purpose Repeated cone-beam CT (CBCT) scans for image-guided radiotherapy (IGRT)
increase the health risk of radiation-induced malignancies. Patient-enrolled studies to …

With the increased use of X-ray imaging for patient alignment in external beam radiation
therapy, particularly with cone-beam computed tomography (CBCT), the additional dose …

In image guided radiotherapy (IGRT), cone beam computed tomography (CBCT) is an
important tool for patient positioning and verification before treatment. Therefore, the CBCT …

BACKGROUND: Currently, CBCT system is an indispensable component of radiation
therapy units. Because of that, it is important in treatment planning and diagnosis. CBCT is …
