computed tomography colonography phantom: construction, validation and literature review
conclusion we constructed and validated a ct colonography phantom with correct density allowing performance of reproducible experiments. materials and methods we found 15 different phantom designs by literature search and compared their advantages and disadvantages based on their description and images. we tested various materials for density and mechanical properties and constructed a phantom ...
متن کاملComputed Tomography Colonography Phantom: Construction, Validation and Literature Review
BACKGROUND Several dedicated computed tomography (CT) colonography phantoms have been described previously. OBJECTIVES To compare their pros and cons and describe the construction of a dedicated phantom that can be easily manufactured. MATERIALS AND METHODS We found 15 different phantom designs by literature search and compared their advantages and disadvantages based on their description a...
متن کاملDesign and Construction of an Affordable Phantom for Electron Density Measurement and Linearity Tests of Computed Tomography Systems
Introduction: The performance of computed tomography is routinely checked using phantoms, which are known as important diagnostic imaging tools. Depending upon the aim of the study, different phantoms are designed, while trying to satisfy certain levels of diversities in their application. Material and Methods: The present study describes the...
متن کامل[Computed tomography colonography image assessment using colon phantom-effects of reconstructed slice thickness].
Computed tomography colonography (CTC) is a robust and reliable imaging test of the colon. Recent studies show good sensitivity for the identification of nonpolypoid (flat) lesions as well. The purpose of this study was to determine the accuracy and reproducibility of a volume-rendering (VR) and virtual gross pathology (VGP) technique for detecting a polypoid lesion phantom by varying slice thi...
متن کاملComputed tomography colonography for colorectal cancer screening.
Colorectal cancer screening has been shown to help prevent cancer-related death. Concerns about suboptimal adherence to conventional colonoscopy has led to the search for alternative screening modalities. Computed tomography colono-graphy (CTC) is a highly sensitive and minimally invasive alternative modality. The American College of Radiology has established a standardized reporting system for...
