Hauv thaj tsam ntawm kev phais tsis muaj teeb pom kev zoo, R9, R11, thiab R13 yog cov cim tseem ceeb rau kev ntsuas lawv.xim rendering zog. Ua ke, lawv txiav txim siab qhov tseeb xim ntawm cov ntaub so ntswg nyob rau hauv lub teeb.
Cias muab:
R9sawv cev rau lub peev xwm los tsim dua tshiabliab saturated.
R11sawv cev rau lub peev xwm los tsim dua tshiabsaturated ntsuab.
R13sawv cev rau lub peev xwm los tsim dua tshiabCaucasian (dawb) tawv nqaij.
Nov yog cov lus piav qhia ntxaws:
Lub tswv yim tseem ceeb: Xim Rendering Index (CRI)
Txhawm rau nkag siab R9, R11, thiab R13, ib qho yuav tsum nkag siab ua ntejXim Rendering Index (CRI).
CRI: Cov ntawv luv rau Xim Rendering Index. Nws yog tus lej ntawm 0 txog 100 uas ntsuas lub teeb ci lub peev xwm los ua siab ncaj rov tsim cov xim ntawm cov khoom piv rau lub teeb pom kev zoo (xws li lub teeb ntuj). Tus nqi CRI siab dua qhia tau tias muaj tseeb thiab muaj xim zoo nkauj dua.
Ra: Qhov no yogtus nqi nruab nrab ntawm CRI. Nws yog xam los ntawm qhov nruab nrab ntawm qhov ntsuas xim rendering peev xwm ntawm lub teeb ci hla 8 tus qauv xim qauv (R1-R8).Ra yog qhov taw qhia feem ntau siv yav dhau los.
Txawm li cas los xij, cov zej zog kho mob tau pom tias kev cia siab rau tus nqi Ra tsuas yog tsis txaus rau kev txiav txim siab lub teeb pom kev zoo ntawm cov teeb phais. Qhov no yog vim Ra (raws li R1-R8) tsis muaj kev ntsuam xyuas ntawm qhov tseem ceeb ntawm cov xim rendering peev xwm xav tau rauntshav thiab ntaub so ntswg. Qhov no yog vim li cas R9, R11, thiab R13 tau dhau los ua qhov tseem ceeb heev.
Cov ntsiab lus tshwj xeeb thiab qhov tseem ceeb ntawm txhua qhov ntsuas
1. R9 - Xim Rendering Index rau Saturated Liab
Sawv cev Xim: Liab liab.
Qhov tseem ceeb hauv Kev Kho Mob: Nov yog ib qho ntawmtseem ceeb tshaj plawsntsuas. R9 muaj feem cuam tshuam ncaj qha rau tus kws phais lub peev xwm paub qhov txawvntshav, hlab ntsha, leeg, leeg, thiab ntau yam ntaub so ntswg. Tus nqi R9 qis tuaj yeem ua rau cov ntshav tshwm tsaus lossis tsaus nti, ua rau nws nyuaj rau kev sib txawv ntawm cov ntshav oxygenated thiab deoxygenated thiab kom paub meej cov hlab ntsha zoo thiab cov ntaub so ntswg, ua rau muaj kev pheej hmoo ntawm kev phais.
Kev lag luam Standard: High-zoo phais tsis muaj teeb pom kev zoo feem ntau xav tau R9 >50, thiab feem ntau ntau dua (qee qhov saum toj kawg nkaus - cov khoom lag luam xav tau R9 > 90).
2. R11 - Xim Rendering Index rau Saturated Ntsuab
Sawv cev Xim: Saturated ntsuab.
Qhov tseem ceeb hauv Kev Kho Mob: Ntsuab yog xim ntxiv rau liab. Kev yug me nyuam zoo ntawm ntsuab muab qhov sib txawv ntawm cov xim liab, pab cov kws phaissib txawv ntawm cov ntaub so ntswg thiab cov qauv sib txawvmeej dua. Piv txwv li, ntawm cov nqaij tawv nqaij daj, cov leeg liab, thiab cov mucosa liab, cov xim ntsuab zoo tuaj yeem muab kev nkag siab zoo ntawm cov xim gradation.
Kev lag luam Standard: High-zoo phais tsis muaj teeb pom kev zoo feem ntau xav tau R11 >80.
3. R13 - Xim Rendering Index rau Caucasian tawv Tone
Sawv cev Xim: Ib xim ze rau Caucasian (dawb) daim tawv nqaij laus.
Qhov tseem ceeb hauv Kev Kho Mob: Qhov ntsuas no feem ntau yog siv los ntsuas cov xim fidelity ntawm lub teeb thaum illuminating lubdaim tawv nqaij. Nws pab kws kho mob ntsuas kom raugdaim tawv nqaij ntshav ncig, pallor, jaundice, cyanosis, thiab lwm yam kab mob. Txawm hais tias nws tau pib txhais raws li Caucasian cov tawv nqaij laus, nws lub hauv paus ntsiab lus tseem ceeb rau kev saib xyuas cov ntshav oxygen thiab kev noj qab haus huv ntawm cov tib neeg nrog rau txhua yam tawv nqaij.
Kev lag luam Standard: High-zoo phais tsis muaj teeb pom kev zoo feem ntau xav tau R13 >90.
Cov ntsiab lus thiab niaj hnub yuav tsum tau ua rau phais teeb pom kev zoo
Yav dhau los, kev yuav khoom hauv tsev kho mob tsuas yog nrhiavRau> 90los yogRau > 95. Txawm li cas los xij, tam sim no tau nkag siab tias lub teeb muaj peev xwm muaj tus nqi Ra siab tab sis R9 qis heev, uas yog qhov txaus ntshai heev hauv kev phais.
Yog li ntawd, tus qauv niaj hnub rau lub teeb zoo nyob rau sab saum toj -tier phais shadowless teeb yog:
Tsis tsuas yog tus nqi siab Ra (feem ntau ntau dua lossis sib npaug rau 95) tab sis kuj tseem muaj cov xim tshwj xeeb ua cov cim xws li R9, R11, thiab R13.
Koj tuaj yeem xav txog nws li no:
Rau (R1-R8): Qhov no yog "cov qhab-nees hauv paus", kom ntseeg tau tias cov xim ntawm cov khoom raug ua ncaj ncees.
R9, R11, R13: Cov no yog cov "cov qhab nia tshwj xeeb", tshwj xeeb yog ntsuas cov peev txheej tseem ceeb hauv cov ntsiab lus kho mob.
Thaum soj ntsuam lub teeb pom kev phais tsis muaj duab ntxoov ntxoo, nco ntsoov thov tus neeg muag khoom muab daim ntawv qhia ua tiav xim rendering Performance index nrog rauRa, R9, R11, thiab R13. Rau lub teeb phais zoo heev, tag nrho cov ntsuas no yuav tsum nyob rau theem siab heev.
