Quantum optimization algorithms for CT image segmentation from X-ray data
Kyungtaek Jun
Computed tomography (CT) is an important imaging technique used in medical analysis of the internal structure of the human body. Previously, image segmentation methods were require…
Highly accurate quantum optimization algorithm for CT image reconstructions based on sinogram patterns
Kyungtaek Jun
Computed tomography (CT) has been developed as a non-destructive technique for observing minute internal images of samples. It has been difficult to obtain photo-realistic (clean o…
Noise-resistant reconstruction algorithm based on the sinogram pattern
Byung Chun Kim, Hyunju Lee, Kyungtaek Jun
We introduce a new CT image reconstruction algorithm that is less affected by various artifacts. The new reconstruction algorithm is a method of minimizing the difference between s…
Virtual Alignment Method and its application to the dental prostheses and diagnosis
Kyungtaek Jun, Seokhwan Yoon, Jae-Hong Lim +1
The recent proposal of a new alignment solution for X-ray tomography, Virtual alignment method (VAM) allowed a more accurate method to remove the possible errors that limit the res…
Possibility of using Parallel beam CT in dental treatment by correction of movement errors with virtual Alignment Method
Seokhwan Yoon, Seong-Kyun Kim, Kyungtaek Jun
The purpose of this study is to correct the movement errors that may occur because of the patients' movement during the CT scanning and thus, to obtain more precise CT images, addi…
Alignment Methods and Analysis of Tilt Angle Range for the Data Scanned in Electron Tomography
Dongwook Kim, Kyungtaek Jun
Electron tomography has been studied in various fields. Various methods have been developed to align projection sets to construct ideally focused reconstruction. In this paper, we…
Alignment Theory of Parallel-beam CT Image Reconstruction for Elastic-type Objects using Virtual Focusing Method
Kyungtaek Jun, Dongwook Kim
X-ray tomography has been studied in various fields. Although a great deal of effort has been directed at reconstructing the projection image set from a rigid-type specimen, little…
Alignment Solution for CT Image Reconstruction by Fixed Point and Virtual Rotation Axis
Kyungtaek Jun, Seokhwan Yoon, Kyu Kwon
Since X-ray tomography is now widely adopted in many different areas, it becomes more crucial to find a robust routine of handling tomographic data to get quality reconstructed ima…
