The skull serves as a protective cavity for the brain, sensory organs, nerve system, and blood vessels. Any blow or a high impact on the skull could cause a break or fracture that is fatal and life-threatening. CT scans are sensitive in detecting such fractures, but many emergency cases also occur outside office hours, where radiologists are often not available for immediate diagnosis. The workflows for fracture detection are also sometimes tedious and time-consuming due to slice-wise inspection. Hence, fracture detection on CT skull images can be improved if the images can be viewed in a single plane. Remapping the 3D skull surface onto a 2D image can give better visualization and reduce the time-consumed for skull fracture detection. The Peirce Quincuncial Projection, which is a stereographic projection - is used to remap 2D skull images. The remapped images were further flattened out using three different methods: mean, maximum, and 90th percentile. The produced images were overlaid with segmented images to determine the sensitivity of the remapping system. For this study, 88 volumes of CT skull images were used. A fracture region-of-interest (ROI) was counted as detected if at least 10% of pixels had intensity | Translation - Malay
Kranium membentuk kaviti untuk melindungi otak, sistem saraf, organ-organ indera dan salur-salur darah yang berada di bawahnya. Retakan pada kranium boleh menyebabkan maut dan kecederaan trauma pada otak yang serius. Imbasan CT sangat sensitif dalam mengesan retakan. Walau bagaimanapun, banyak kes-kes kecemasan berlaku di luar waktu pejabat di mana ahli radiologi kebiasaanya tiada untuk diagnosis segera. Tatakerja untuk pengesanan retakan juga memakan masa kerana pemeriksaan imej dilakukan secara hirisan demi hirisan. Oleh itu, pengesanan retakan pada imej kranium CT boleh diperbaharui jika imej dapat dilihat secara sekaligus seperti pemetaan semula permukaan 3D kranium kepada imej 2D. Pemetaan semula imej dapat dilakukan melalui unjuran Peirce Quincuncial iaitu unjuran stereografik. Imej yang tertransformasi akan diratakan dengan menggunakan tiga kaedah: purata, maksimum dan 90 persentil. Imej yang terhasil akan dilabelkan dengan imej yang disegmen untuk menguji sensitiviti sistem pemetaan semula. Untuk kajian ini, 88 subjek telah digunakan. Retakan pada kawasan kepentingan (ROI) dikira wujud jika ≤10% piksel mempunyai keamatan |
