Performance evaluation of a CT scanner is quite challenging in modern CT scanners due to differences in make, model, and manufacturer specifications. This chapter is mostly focused on AAPM Report 233 on the performance evaluation of CT systems.
28 gru 2019 · OVERVIEW. This page discusses an important nuance of CT studies that is commonly overlooked: proper windowing during the analysis of images. How a study is windowed has a significant impact on the ability to interpret the patient’s anatomy as well as any pathology.
predicting the performance of a CT system and protocols for clinical imaging tasks. A prevalent new CT technology uses statistical and iterative reconstruction (IR) algorithms to decrease image noise to facilitate use of decreased radiation dose levels.
The Computed Tomography (CT) Scanner Task Group was formed to pro-vide a reference document of suggested procedures for acceptance testing of CT systems for clinical medical physicists.The AAPM first addressed per-formance testing of CT systems with the publication of AAPM Report No.
13 sie 2019 · The rapid development and complexity of new x-ray computed tomography (CT) technologies and the need for evidence-based optimization of image quality with respect to radiation and contrast media dose call for an updated approach towards CT performance evaluation.
This document aims to supplement and complement existing and prior equipment performance testing guidelines (e.g., AAPM Report 741) by addressing the more advanced aspects of current CT systems, such as IR and TCM.
1 lip 2020 · This study aimed to optimize the CT window setting at 120 kVp, by assessing the best window width to detect the solid lesion component as indicator of invasiveness of lung adenocarcinoma in SSNs, with histopathology as reference standard.
