Cone beam CT scatter correction tool is a software that can correct the scatter artifacts in the CBCT images. The software applies the trained multiple spectral scatter estimation model which is proposed in the paper ‘A generalized image quality improvement strategy of cone-beam CT using multiple spectral CT labels in Pix2pix GAN’.

2024年12月17日 · However, the image quality of dual-energy CBCT remains constrained by the Compton scattered x-ray photons. The objective of this study is to develop a novel scatter correction method, named e-Grid, for DL-FPD based CBCT imaging.

There have been numerous efforts in improving CBCT image quality using scatter correction: such as hardware improvement by adding anti-scatter grid 3, x-ray beam blocker with a strip pattern 2, or a lattice-shaped lead beam stopper 4; or software improvement with iterative filtering 5, raytracing 6, model-based approach 7, or Monte Carlo (MC ...

2022年4月7日 · This study proposes a simple and effective postprocessing software-based correction method of scatter artifacts in CBCT scans without specific prior knowledge. Methods. We propose the empirical scatter correction (ESC), which generates scatter-like basis images from each projection image by convolution operations.

2024年8月1日 · This study aims at developing a simple and rapid Compton scatter correction approach for cone-beam CT (CBCT) imaging. Approach. In this work, a new Compton scatter estimation model is established based on two distinct CBCT scans: one measures the full primary and scatter signals without anti-scatter grid (ASG), and the other measures a portion ...

2024年12月17日 · Abstract: Objective: The aim of this study is to validate the effectiveness of an energy-modulated scatter correction method in suppressing scatter in photon-counting detector (PCD)-based cone beam CT (CBCT) imaging. Approach: The scatter correction method, named e-Grid, which was initially applied to dual-layer flat-panel detector (DLFPD ...

2016年11月30日 · X-ray scatter is a significant impediment to image quality improvements in cone-beam CT (CBCT). The authors present and demonstrate a novel scatter correction algorithm using a scatter estimation method that simultaneously combines multiple Monte Carlo (MC) CBCT simulations through the use of a concurrently evaluated fitting function, referred ...

2023年10月1日 · In this study, we proposed an unsupervised contrastive learning method for CBCT scatter correction. Initially, we transformed low-quality CBCT into high-quality synthetic pCT (spCT) and generated forward projections of CBCT and spCT.

2024年12月17日 · However, the image quality of dual-energy CBCT remains constrained by the Compton scattered x-ray photons. Purpose: The objective of this study is to develop a novel scatter correction method, named e-Grid, for DL-FPD based CBCT imaging.

Cone-beam CT (CBCT) is being increasingly used in modern radiation therapy for patient setup and adaptive replanning. However, due to the large volume of x-ray illumination, scatter becomes a rather serious problem and is considered as one …
