Except for critical basic implementations seen in historical records, the sheer quantity of similar frameworks, platforms, and apps available may be deceptive. Striking a balance between 3D certified displays and incorporated complicated features continues to be difficult. Geometrically precise point clouds and meshes are the result of cutting-edge methodology (computer vision, reverse engineering, and digital photogrammetry), cutting-edge technology (LiDAR, laser scanners, and unmanned aerial vehicles), and random research approaches. They are a by-product of the procedure. As the precision, size, and complexity of these things rise, the capabilities of present technology to manage them deteriorate. In this paper we propose a method for Development of a low-cost 3d visualization platform, capable of interactively perform tasks. Moreover, we seek to verify the methodological aspect of implementing steps and simplified algorithms in a virtual reality.

Background: In 2021, the Korean government proposed a new CT diagnostic reference level. This study performed a nationwide survey and developed new DRLs and AD for 13 common CT examinations. We compared other countries’ DRLs for CT examinations. Methods: This study investigated the CTDIvol and DLP of the 12 types of CT protocols for adults and brain CT protocol for pediatrics. A total of 7829 CT examinations were performed using 225 scanners. We defined the DRLs values in the distribution of radiation exposure levels to determine the nationwide patient dose and distribution status of the dose. Results: This study showed that the new Korean national CT DRLs are slightly higher or similar to those of previous surveys and are similar or lower than those of other countries. In some protocols, although the DLP value increased, the CTDIvol decreased; therefore, it can be concluded that the patient’s dose in CT examinations was well managed. Conclusions: The new CT DRLs were slightly higher than or similar to that of the previous survey and were evaluated to be similar or lower than CT DRLs of other countries. These DRLs will be used for radiation optimization and effective dose calculation for an individual.
