一、概述

這款用(yong)于(yu)檢測(ce)X射(she)線(xian)(xian)攝(she)(she)影(ying)(ying)設(she)備會聚濾線(xian)(xian)柵與(yu)有用(yong)線(xian)(xian)束中(zhong)心(xin)(xin)對準(zhun)(zhun)(zhun)的(de)(de)工(gong)(gong)(gong)具是針對醫(yi)學影(ying)(ying)像(xiang)領(ling)域開發(fa)的(de)(de)一種創新產(chan)品(pin)。它通(tong)過(guo)膠片(pian)曝光成像(xiang)來(lai)評估(gu)放(fang)(fang)射(she)攝(she)(she)影(ying)(ying)濾線(xian)(xian)柵與(yu)X射(she)線(xian)(xian)束中(zhong)心(xin)(xin)的(de)(de)對準(zhun)(zhun)(zhun)情(qing)況，并且可(ke)以(yi)(yi)提供清晰(xi)的(de)(de)成像(xiang)質(zhi)量(liang)(liang)(liang)(liang)。該工(gong)(gong)(gong)具采用(yong)了高質(zhi)量(liang)(liang)(liang)(liang)的(de)(de)材(cai)料和(he)特(te)殊的(de)(de)工(gong)(gong)(gong)藝制造，以(yi)(yi)確(que)保其(qi)精度和(he)穩定性(xing)。使用(yong)這種工(gong)(gong)(gong)具，醫(yi)療專業人員可(ke)以(yi)(yi)在(zai)現場(chang)快速(su)、準(zhun)(zhun)(zhun)確(que)地評估(gu)X射(she)線(xian)(xian)設(she)備的(de)(de)對準(zhun)(zhun)(zhun)情(qing)況，從而(er)(er)確(que)保成像(xiang)結(jie)果的(de)(de)準(zhun)(zhun)(zhun)確(que)性(xing)和(he)可(ke)靠性(xing)。該工(gong)(gong)(gong)具的(de)(de)操(cao)(cao)作非(fei)(fei)常(chang)簡便。在(zai)進(jin)行(xing)檢測(ce)之前，將工(gong)(gong)(gong)具放(fang)(fang)置在(zai)待(dai)測(ce)試設(she)備的(de)(de)路(lu)徑上，然后進(jin)行(xing)正常(chang)的(de)(de)X射(she)線(xian)(xian)拍攝(she)(she)。通(tong)過(guo)對膠片(pian)進(jin)行(xing)觀察和(he)分析，可(ke)以(yi)(yi)判斷出放(fang)(fang)射(she)攝(she)(she)影(ying)(ying)濾線(xian)(xian)柵是否與(yu)X射(she)線(xian)(xian)束中(zhong)心(xin)(xin)對齊(qi)。如果對齊(qi)，成像(xiang)質(zhi)量(liang)(liang)(liang)(liang)將會非(fei)(fei)常(chang)清晰(xi)；反之，若不對齊(qi)，則可(ke)能產(chan)生模糊(hu)或不準(zhun)(zhun)(zhun)確(que)的(de)(de)成像(xiang)結(jie)果。該工(gong)(gong)(gong)具的(de)(de)特(te)點在(zai)于(yu)其(qi)高效率。它不僅可(ke)以(yi)(yi)迅速(su)進(jin)行(xing)檢測(ce)，而(er)(er)且在(zai)現場(chang)操(cao)(cao)作時也(ye)能提供準(zhun)(zhun)(zhun)確(que)的(de)(de)結(jie)果，減少了醫(yi)療專業人員的(de)(de)工(gong)(gong)(gong)作量(liang)(liang)(liang)(liang)和(he)排除錯(cuo)誤的(de)(de)時間。
