In image-guided radiotherapy (IGRT), four-dimensional cone-beam computed tomography (4D-CBCT) is critical for assessing tumor motion during a patients breathing cycle prior to beam delivery. However, generating 4D-CBCT images with sufficient quality requires significantly more projection images than a standard 3D-CBCT scan, leading to extended scanning times and increased imaging dose to the patient. To address these limitations, there is a strong demand for methods capable of reconstructing high-quality 4D-CBCT images from a 1-minute 3D-CBCT acquisition.

Objective: Dynamic navigation approaches are widely employed in the context of implant placement surgery. Implant surgery can be divided into immediate and delayed surgery according to the time of implantation. This retrospective study was developed to compare the accuracy of dynamic navigation system for immediate and delayed implantations.

While radiation hazards induced by cone-beam computed tomography (CBCT) in image-guided radiotherapy (IGRT) can be reduced by sparse-view sampling, the image quality is inevitably degraded. We propose a deep learning-based multi-view projection synthesis (DLMPS) approach to improve the quality of sparse-view low-dose CBCT images. In the proposed DLMPS approach, linear interpolation was first applied to sparse-view projections and the projections were rearranged into sinograms; these sinograms were processed with a sinogram restoration model and then rearranged back into projections.

Bone regeneration is a complex process influenced by inflammation and pathological conditions. Efforts to enhance this process include chemical and physical interventions, with PBMT therapy showing promise in improving bone regeneration. Despite conflicting findings in existing literature, this review aims to synthesize clinical evidence on using therapy (PBMT) in bone regeneration and explore its potential clinical applications.

Objective: This study aims to evaluate the anatomical configuration of the mesiobuccal root of the maxillary first molar and assess the prevalence of the mesiobuccal canal (MB2).
Materials And Methods: A total of 307 high-resolution cone-beam computed tomography (CBCT) images of maxillary molars were analyzed. These images were classified based on the anatomical configuration and prevalence of the MB2 canal.
