Summary: The aim of this study was to provide a tool to aid medical doctors in planning endovascular surgery by quickly detecting stenotic vessels and quantifying the degree of stenosis. The use of skeletonization improved the visualization of vessels and the distance transform provided a linear representation of the diameter of critical vessels selected by the user. The system also estimated the exact distance between landmarks and the occlusion, which is crucial information for surgery planning. The proposed tool offers the advantage of examining chosen vessels in a linear representation free from tortuous vascular courses and vessel crossings.

Summary: This study evaluated the impact of small and large FOVs on organ absorbed dose in CBCT devices using ImPACT software. Results indicated that larger FOVs led to higher organ absorbed doses, with salivary glands being the most affected organ.

Summary: This study investigated the effects of varying arc exposure trajectories on radiation dose and image quality in abdominal C-arm CBCT interventional procedures. The results showed that the arc trajectory affected organ doses, with higher doses for posterior located organs. Image noise was higher in vascular protocols compared to soft tissue protocols, and there were significant differences in SNR, CNR, and in-plane spatial resolution among different soft tissue protocols.

Summary: This study evaluated the anatomical and volumetric predictability of CBCT-based VPP software for SPECT/CT imaging results in HCC patients undergoing TARE. The results showed that the CBCT-based VPP software accurately and reliably predicted the anatomical and volumetric results of Tc-99m-MAA SPECT/CT in HCC patients during TARE.

Summary: This study found that there were almost no significant differences in the detectability and visibility of cystic lesions between low-dose CBCT imaging and the standard protocol. Both imaging protocols showed similar performance in lesion size assessment, but with an underestimation of the actual size.

Summary: This study evaluated the effectiveness of different CBCT software in reducing blooming artifacts when examining teeth with intracanal posts. The use of the e-Vol DX BAR filter eliminated blooming artifacts, while the PreXion3D Image Analysis System may result in significant differences in the measured post diameters compared to the actual values.

Summary: A significant reduction in effective dose for CBCT-DCG in healthy volunteers is achievable by decreasing the scanning field of view (FOV) without compromising diagnostic capability. CBCT-DCG is a potential first-line imaging test for evaluating the lacrimal drainage system, allowing for functional assessment of lacrimal drainage.

Summary: This study aimed to evaluate the influence of patient characteristics, such as sex, skeletal malocclusion (Class I, Class II, and Class III), and facial type (brachycephalic, mesocephalic, and dolichocephalic), on the width, height, thickness, and volume of the mandibular angle. The results showed that sex significantly influenced all the analyzed variables, with males generally having higher values. In some cases, skeletal malocclusion and facial type also influenced the width and height variables of the mandibular angle.

Summary: We propose a motion estimation and motion correction approach for oral and maxillofacial cone beam CT scans based solely on 2D projection images. This algorithm improves the visualization quality of motion impaired scans, eliminating the need for re-scans and reducing radiation dosage for patients.

Summary: This study aimed to classify 10 cone-beam computed tomographic (CBCT) devices based on their ability to detect fine endodontic structures. The results showed that these devices performed differently for different endodontic tasks, with only a few devices maintaining a high level of detection capability in the presence of metal.

Summary: This study used CBCT to evaluate the root canal morphology of primary molars. The results showed a wide variation in the number of roots and canals, with 3 canals and 3 roots being the most common in maxillary first molars. Vertucci's type IV was the most common canal type, and the buccal surface had the highest percentage of concavities. These findings emphasize the need for careful treatment of primary molars due to their complex root canal anatomy.

Summary: The study analyzed the variation in orthodontic diagnostic measurements on lateral cephalograms reconstructed from ULD-LD CBCT scans compared to standard lateral cephalograms. Results showed that there were small differences in variation between the two imaging methods, supporting the use of ULD-LD CBCT with reconstructed lateral cephalograms for orthodontic diagnostic purposes due to the lower radiation dose.
