Hauv kev tsim khoom siv kho mob, qhov tseeb ntawm cov khoom siv kho mob radiotherapy siab yog ncaj qha cuam tshuam nrog kev ua tau zoo ntawm cov khoom siv thiab cov txiaj ntsig kho mob ntawm cov neeg mob. XYZT precision gantry txav platform vam khom cov txiaj ntsig tshwj xeeb ntawm cov khoom granite, muab kev lees paub zoo rau kev txiav, drilling thiab lwm yam haujlwm ntawm tib neeg cov ntaub so ntswg simulators.
Kev ruaj khov zoo heev ua kom muaj qhov chaw tseeb
Kev ua cov khoom siv kho mob radiotherapy yuav tsum tau qhov tseeb siab heev, thiab txhua qhov kev hloov me me yuav cuam tshuam rau qhov tseeb ntawm cov ntaub so ntswg mob qog noj ntshav thaum lub sijhawm kho mob radiotherapy. XYZT precision gantry movement platform granite components, cov qauv sab hauv yog ntom thiab sib xws, nrog kev ruaj khov zoo heev. Nws qhov ceev yog siab txog li 2.6-2.7g / cm³, uas tuaj yeem tiv taus kev cuam tshuam los ntawm kev co sab nraud, txawm tias nyob rau hauv qhov chaw nyuaj ntawm lub rooj cob qhia, tab sis kuj txo qhov loj ntawm lub platform los ntawm ntau dua 80%. Thaum txiav thiab khawb cov ntaub so ntswg tib neeg, cov khoom granite muab kev txhawb nqa zoo rau lub platform kom ntseeg tau tias qhov chaw raug ntawm lub cuab yeej lossis cov cuab yeej txiav, nrog qhov tseeb txog li ± 0.01 hli. Piv txwv li, thaum ua cov nplooj collimator ntawm cov khoom siv kho mob radiotherapy, qhov chaw thiab cov duab ntawm cov nplooj tuaj yeem tswj tau meej, yog li cov duab tuaj yeem tsom mus rau qhov chaw mob qog noj ntshav, zam kev puas tsuaj rau cov ntaub so ntswg noj qab haus huv ib puag ncig.
Kev nruj siab kom tau raws li qhov xav tau ntawm kev ua haujlwm siab
Cov txheej txheem txiav thiab khawb ntawm cov ntaub so ntswg tib neeg muaj cov kev cai nruj heev rau kev ruaj khov ntawm cov khoom siv. Cov khoom siv granite muaj kev ruaj khov siab thiab lub zog compressive txog li 200-300MPa, uas tuaj yeem tiv taus lub zog txiav loj uas siv los ntawm cov cuab yeej hauv cov txheej txheem ua tiav yam tsis muaj kev hloov pauv pom tseeb. Thaum lub sijhawm ua haujlwm khawb ntawm qhov kev sim, lub platform tuaj yeem ruaj khov kom tiv thaiv kev hloov chaw ntawm qhov chaw khawb lossis qhov sib txawv ntawm lub qhov vim yog lub zog. Hauv cov khoom siv kho mob txaj rau kev tsim cov khoom siv radiotherapy, kev khawb siab raug yog qhov yuav tsum tau ua hauv cov khoom siv uas ua qauv rau cov qauv pob txha tib neeg kom teeb tsa cov khoom siv. Cov khoom siv granite ntawm XYZT precision gantry txav platform txhawb nqa kev ua haujlwm ruaj khov ntawm lub platform, thiab qhov yuam kev qhov chaw raug ntawm qhov drilled yog tswj tau hauv ± 0.02 hli, kom ntseeg tau tias lub txaj kho mob tuaj yeem kho qhov chaw ntawm tus neeg mob thaum siv, thiab ua tau raws li cov kev cai ntawm cov khoom siv radiotherapy rau qhov chaw siab.
Thermal stability tswj tau qhov tseeb ntawm kev ua haujlwm tas mus li
Thaum lub sijhawm ua cov khoom siv kho mob, kev txiav cua sov, kev hloov pauv kub ib puag ncig thiab lwm yam yuav cuam tshuam rau qhov tseeb ntawm kev ua. Qhov coefficient ntawm thermal expansion ntawm granite yog qis heev, feem ntau yog 5-7 × 10⁻⁶ / ℃, thiab qhov loj me hloov me ntsis thaum qhov kub hloov pauv. Thaum ua cov khoom siv simulation tib neeg ntev, txawm tias qhov kub ntawm lub chaw ua haujlwm hloov pauv 5-10 ° C vim yog kev ua haujlwm ntawm cov khoom siv, cua txias thiab lwm yam, lub platform txhawb nqa los ntawm cov khoom siv granite tseem tuaj yeem tswj tau qhov loj me kom ntseeg tau tias qhov kev txiav thiab kev khawb raug tsis cuam tshuam. Piv txwv li, hauv kev txiav qhov tseeb ntawm cov ntaub ntawv uas ua rau cov ntaub so ntswg mos ntawm tib neeg, qhov tiaj tiaj thiab tiav ntawm qhov chaw txiav tuaj yeem ua kom tau raws li qhov yuav tsum tau ua ntawm cov khoom siv kho mob radiotherapy thiab cov ntaub so ntswg tib neeg, thiab txhim kho kev nyab xeeb thiab kev ua haujlwm ntawm cov khoom siv kho mob radiotherapy.
