Kev kho hniav kho hniav CBCT yog lub npe luv rau Cone beam CT.Raws li lub npe qhia, nws yog cone beam projection computer reconstruction tomography khoom.Nws lub hauv paus ntsiab lus yog tias lub tshuab hluav taws xob xoo hluav taws xob ua lub voj voog ncig ntawm lub cev qhov projection nrog cov tshuaj hluav taws xob tsawg (feem ntau tam sim no ntawm lub raj yog li 10 mA).Tom qab ntawd, cov ntaub ntawv tau txais nyob rau hauv "kev sib tshuam" tom qab digital projection nyob ib ncig ntawm lub projection lub cev rau ntau zaus (180 zaug - 360 zaug, nyob ntawm cov khoom) yog "recombined thiab reconstructed" nyob rau hauv lub computer kom tau ib tug peb-dimensional duab.Lub hauv paus ntsiab lus ntawm cov ntaub ntawv tau txais los ntawm CBCT yog txawv kiag li ntawm ib txwm sector scan CT, thiab algorithm hauv paus ntsiab lus ntawm tom qab lub computer reorganization yog zoo sib xws.
Rau kev kho hniav CBCT, lub tiaj tiaj tus ntes yog lub hauv paus tseem ceeb cuam tshuam rau nws cov duab zoo, thiab cov khoom lag luam thiab kev ua haujlwm ntawm lub vaj huam sib luag tiaj tiaj muaj feem cuam tshuam rau nws cov duab zoo.Kev kho hniav X-ray ca vaj huam sib luag ntes nws tus kheej tsim thiab tsim los ntawm Haobo coj mus rau hauv tus account cov kev cai tshwj xeeb ntawm kev kho hniav nqaim thiab tus ncej siab, thiab tsim nyog rau daim ntawv thov kev kho mob thiab kho hniav.
