Cov qauv ntawm X-ray digital rho tawm angiography tshuab
X-ray tiam system
1. High-voltage generator: siv qhov nruab nrab zaus los yog high-frequency technology, tswj los ntawm microprocessor, ua kom muaj zog ruaj khov, muaj peev xwm ua kom muaj peev xwm ua tau sai ntawm ntau hom mem tes, thiab cov duab nrawm tuaj yeem siab li 150 ntas ib thib ob.
2. X-ray raj: tuaj yeem tiv taus lub nra ntawm lub plawv tsis tu ncua.
Duab system
Cov duab kab ke tsim los ntawm cov vaj huam sib luag tiaj tus: Txij li cov vaj huam sib luag tiaj tiaj yog cov tseem ceeb ntawm cov duab kaw lus, nws qhov kev ua tau zoo yog ncaj qha cuam tshuam rau cov duab zoo thiab kev siv hluav taws xob.
1. Lub quantum detection efficiency nqi txuas ntxiv mus, mus txog 77% (txog 71% thaum lub sij hawm fluoroscopy);
2. Ib pixel loj ntawm 200μm yog txaus kom tau raws li qhov kev daws teeb meem ntawm 1024 × 1024;
3. Bandwidth hais txog kev sib raug zoo ntawm chav tsev pixel thiab AD converter. Txhua kab lossis kem ntawm lub vaj huam sib luag broadband txuas nrog AD converter los pab kom cov ntaub ntawv xa mus tau tshwj xeeb thiab ua tau zoo, thaum lub vaj huam sib luag nqaim muaj 120 kab (kem). Pixels qhia AD converter, thiab cov ntaub ntawv tsuas yog muab ntim thiab xa mus;
4. Dynamic range: FPD (Flat Panel Display) muaj qhov sib txawv loj hauv dynamic ntau yam. Qhov siab tshaj plaws dynamic ntau tus nqi tuaj yeem ncav cuag 4nGy-13mGy.
Cov ntaub ntawv tau txais thiab khaws cia system
Loj-muaj peev xwm ntawm lub sijhawm cov duab khaws cia feem ntau yog siv cov khoom siv dynamic, uas yuav tsum tau xa los ntawm lub tsheb npav video thiab siv rau kev nyeem ntawv thiab sau ntawv tswj nrog lub khoos phis tawj tsheb npav interface, thiab cov duab hloov pauv ntawm lub cim xeeb thiab lub hard disk yuav tsum tau paub.
Computer system
Lub khoos phis tawj feem ntau yog siv rau kev tswj hwm thiab cov duab tom qab ua tiav hauv DSA system.
Computer system
1. Lub longitudinal thiab lateral txav ntau ntawm lub txaj catheter yuav tsum loj txaus, thiab nws tuaj yeem tig mus rau sab laug thiab sab xis kom nce qhov chaw txav mus los thiab pab txhawb qhov chaw thiab cawm tus neeg mob.
2. Cov khib nyiab muaj ib hom kev tsheb ciav hlau uas raug tshem tawm thiab ib hom kev ruaj khov hauv pem teb. Tam sim no, muaj DSA system uas tsis muaj tsheb ciav hlau, tsis muaj axis ruaj khov, thiab kev txav mus los dawb.
