isici sobuchwepheshe

1)Isizinda se-BIN (I-Background Identification of Normal) ayinaba ubuchwepheshe

Ubuchwepheshe bungakwazi ukubona ngokushesha izinga eliphansi lezinto ezikhipha imisebe yokwenziwa esimweni sesizinda semisebe ephezulu, isikhathi sokuthola kuze kufike kuma-millisecond angu-200, kuyilapho kuvumela imoto ukuthi ibone izinto ezikhipha imisebe ngaphansi kokunyakaza okusheshayo, ezifanele ukutholwa ngokushesha, futhi ingaqinisekisa ukuthi imishini ngeke kube i-alamu yamanga ngenxa yokwanda kwengemuva kakhulu;futhi inganxephezela isikhala semoto esibangelwa ukuncishiswa kwesibalo sangemuva sokuhlolwa kwe-ray, ikhuphule ubuqiniso bemiphumela yokuhlola, ithuthukise amathuba okutholwa, ikakhulukazi ukutholwa okubuthakathaka kwemisebe kuyasiza kakhulu;

2)Umsebenzi wokunqaba we-NORM

Lo msebenzi usetshenziselwa ukukhomba nokwahlulela izinto zemvelo ezinemisebe ye-nuclide.Ukusiza amakhasimende ukuqeda i-alamu impahla yokwenziwa enemisebe noma impahla yemvelo enemisebe;

3)Faka i-algorithm yezibalo ye-SIGMA

Ngesici se-algorithm ye-SIGMA, abasebenzisi bangalungisa kalula ukuzwela kokutholwa kwedivayisi kanye nethuba lokuphozithiza okungamanga, bangathuthukisa ukuzwela kokutholwa kwemithombo ekhipha imisebe ebuthaka kakhulu (njengemithombo ekhipha imisebe elahlekile), noma ekuqaphelweni kwesikhathi eside ku-inthanethi. inqubo yokuvimbela amaphozithi edivayisini angamanga, ukuze yamukele futhi ikhulule ngokukhululeka;
