## What is/are Cbct Reconstruction?

Cbct Reconstruction - Parallel data sets were generated using standard (sCBCT) and iterative (iCBCT) CBCT reconstructions.^{[1]}In this study, a novel DL technique is developed to resolve the memory issue, and its feasibility is demonstrated for CBCT reconstruction from sparsely sampled projection data.

^{[2]}Automatic tumor-supplying vessel detection was performed on up to 4 tumors in each CBCT reconstruction (Liver ASSIST V.

^{[3]}A comparative analysis of the acquired CBCT and micro-CBCT reconstructions was performed.

^{[4]}Aiming at the problem of timeliness of CBCT reconstruction, a CBCT fast short scan reconstruction method is proposed.

^{[5]}200- and 600-projection adaptive 4DCBCT reconstructions achieved more than 0.

^{[6]}The average 3D root mean squared distance between single plane and CBCT reconstruction was 0.

^{[7]}Recent advancements in sparse-view 4D-CBCT reconstruction have opened the possibility to reduce scan time and dose.

^{[8]}In this study, we proposed to use the structure tensor total variation (STV) that penalizes the eigenvalues of the structure tensor for CBCT reconstruction.

^{[9]}As our method does not rely on consistency between projection data and tomography reconstruction it is robust towards truncation, noise and other typical artifacts of CBCT reconstruction.

^{[10]}The challenge in 4D-CBCT reconstruction is the lacked of projections at each phase, which result in a reconstruction image full of streak artifacts and motion blurring with the conventional analytical algorithms.

^{[11]}CONCLUSIONS The proposed 3DA-TVAL3 algorithm can perform efficient and fast computation of CBCT reconstruction using the reduced amount of computer memories.

^{[12]}Four-dimensional (4D) CBCT reconstruction with phase binning is typically used to overcome these difficulties.

## 4d Cbct Reconstruction

The purpose of this paper was to develop a new 4D CBCT reconstruction method to generate a series of high spatiotemporal 4D CBCT images.^{[1]}A commercially available phantom with programmable target motion was programmed with nine target trajectories derived from patient-measured respiratory traces known to span the range of image quality when used for 4D CBCT reconstruction.

^{[2]}Evaluation of intrafraction 4D CBCT reconstruction revealed inclusion of MV only images acquired to remove MV scatter effects.

^{[3]}This algorithm is well fit for 4D CBCT reconstruction with spatial and temporal total variation (TV) regularization, and several authors recently used this approach.

## Iterative Cbct Reconstruction

CONCLUSIONS Using a priori pre-conditioned information can effectively alleviate truncation artefact and assist recovery of peripheral information in iterative CBCT reconstruction.^{[1]}ADVANCES IN KNOWLEDGE: An iterative CBCT reconstruction platform was build using RTK.

## cbct reconstruction technology

Despite that 4D-CBCT reconstruction technology could alleviate the motion blurring artifacts, it introduces severe streaking artifacts due to the under-sampled projections used for reconstruction.^{[1]}Although 4D-CBCT reconstruction technology is available to alleviate the motion blurring artifacts with the strategy of projection sorting followed by independent reconstruction, under-sampling streaking artifacts and noise are observed in the set of 4D-CBCT images due to relatively fewer projections and large angular spacing in each phase.
