Ubuvuzi bwa kirimbuzi
Kwerekana amashusho ni ubuhe?
Kwerekana amashusho yubuvuzi bwa kirimbuzi (nanone bita radionuclide scanning) nigikoresho cyiza cyo gusuzuma kuko kiterekana gusa anatomiya (imiterere) yingingo cyangwa igice cyumubiri, ahubwo imikorere yumubiri.Aya makuru "yimikorere" yemerera ubuvuzi bwa kirimbuzi gusuzuma indwara zimwe na zimwe nubuvuzi butandukanye vuba kuruta ibindi bizamini byubuvuzi byerekana ubuvuzi butanga amakuru ya anatomic (imiterere) yerekeye urugingo cyangwa igice cyumubiri.Ubuvuzi bwa kirimbuzi burashobora kuba ingirakamaro mugupima hakiri kare, kuvura, no gukumira indwara nyinshi kandi bikomeza kwiyongera nkigikoresho gikomeye cyubuvuzi.
KUBIKORWA BYINSHI BY'UBUZIMA Bitanga imiyoborere yubuvuzi bwo kwisuzumisha kwa muganga bwagize uruhare mubuzima bwabo bwa buri munsi muburyo rusange bwa radiologiya (urugero, CT, MR, X-ray, PET, SPECT, nibindi).Nyamara, abanyamwuga muri ibyo bigo, uhereye ku baganga, abatekinisiye, n’abayobozi, kugeza ku bakozi ba PACS / IT, na bo bagiye bumva ububabare bwo kutagira ibisubizo bikwiye bya PACS ku buryo butandukanye.Uburyo bukoreshwa cyane na PACS nuburyo bwo gufata amashusho ya kirimbuzi, harimo PET-CT, SPECT-CT, umutima wa kirimbuzi, nubuvuzi rusange.
Nubwo amashusho ya molekile yerekana amashusho ari make ugereranije numubare wibizamini bikorwa buri mwaka, akamaro kayo ntigomba gusuzugurwa, haba mubuvuzi ndetse nubukungu.PET-CT byagaragaye ko ari modo de modo mugihe cyo gusuzuma kanseri.Indwara z'umutima wa kirimbuzi zabaye uburyo bwo guhitamo umutima udakira.Ubuvuzi rusange bwa kirimbuzi butanga amashusho menshi yerekana amashusho ntayindi nzira ishobora guhura.Amafaranga, PET-CT na kardiologiya ya kirimbuzi biracyari mubikorwa byishyuwe cyane mumashusho yo gusuzuma.
Igituma amashusho yubuvuzi bwa kirimbuzi atandukana nuburyo rusange bwa radiologiya nuko iyambere ishushanya imikorere yumubiri, mugihe iyanyuma ishushanya anatomiya yumubiri.Niyo mpamvu amashusho ya molekuline yerekana amashusho rimwe na rimwe nanone yitwa metabolic imaging.Kugirango dusesengure imikorere yumubiri uhereye kumashusho yabonetse, harasabwa ibikoresho byihariye byo kureba no gusesengura.Ibi bikoresho nibyo rwose bibura muri benshi muri PACS uyumunsi.
Ni muri urwo rwego, Isosiyete ikora ibijyanye n’ubuvuzi yerekana amashusho yifuza guteza imbere ibisekuru bishya PET, SPECT.
Kuki Hitamo Kinheng:
1.Igipimo ntarengwa cya pigiseli irahari
2.Icyerekezo cyiza cya optique
3.Uburinganire bwiza hagati ya pigiseli kugeza kuri pigiseli / Array kuri array
4.TiO2 / BaSO4 / ESR / E60 ibyerekanwa birahari
5.Icyuho cya Pixel: 0.08, 0.1, 0.2, 0.3mm
6.Ikizamini cyo gukora kirahari

Igishushanyo mbonera cyo guteranya:
Ukurikije imikoreshereze yanyuma yuburyo bukusanyirijwe hamwe, hari ubwoko bwinshi bwubukanishi buva Kinheng kugirango buhuze inganda zishinzwe ubugenzuzi n’umutekano.
1D Imirongo ikoreshwa cyane cyane mubikorwa byo kugenzura umutekano, nka Bagger scaneri, Aviation scaneri, 3D scaneri na NDT.Ibikoresho Harimo CsI (Tl), GOS: Filime ya Tb / Pr, GAGG: Ce, scintillator ya CdWO4 nibindi mubisanzwe bahujwe numurongo wa Silicon Photodiode umurongo kugirango usome.
2D array isanzwe ikoreshwa mugushushanya, harimo Ubuvuzi (SPECT, PET, PET-CT, ToF-PET), SEM, kamera ya Gamma.Iyi 2D array isanzwe ihujwe na SIPM array, PMT array yo gusoma.Kinheng itanga 2D array harimo LYSO, CsI (Tl), LSO, GAGG, YSO, CsI (Na), BGO scintillator nibindi.
