Anatomical changes and dosimetric analysis of the neck region based on FBCT for nasopharyngeal carcinoma patients during radiotherapy
CONCLUSION: Significant anatomic and dosimetric changes were observed in the target volumes and OARs. Based on the identified thresholds, replanning at approximately 20 fractions is crucial to ensure adequate target volumes dose and avoid overdosing to the OARs. This approach is clinically feasible and strongly recommended, particularly for centers without access to an adaptive planning system.PMID:38457140 | DOI:10.3233/XST-230280 (Source: Journal of X-Ray Science and Technology)

Predicting the error magnitude in patient-specific QA during radiotherapy based on ResNet
CONCLUSIONS: In this study, error magnitude prediction models with dose difference, gamma distribution, and RDD + EDD are established based on ResNet. The accurate prediction of the error magnitude under different error types can provide reference for error analysis in patient-specific QA.PMID:38457139 | DOI:10.3233/XST-230251 (Source: Journal of X-Ray Science and Technology)

High-resolution X-Ray imaging of small animal samples based on Commercial-Off-The-Shelf CMOS image sensors
J Xray Sci Technol. 2024 Feb 27. doi: 10.3233/XST-230232. Online ahead of print.ABSTRACT An automated system for acquiring microscopic-resolution radiographic images of biological samples was developed. Mass-produced, low-cost, and easily automated components were used, such as Commercial-Off-The-Self CMOS image sensors (CIS), stepper motors, and control boards based on Arduino and RaspberryPi. System configuration, imaging protocols, and Image processing (filtering and stitching) were defined to obtain high-resolution images and for successful computational image reconstruction. Radiographic images were obtained for anima...
