Optos公司推出廣域快速視網(wǎng)膜影像檢查設(shè)備 【?2006-07-10 發(fā)布?】 美迪醫(yī)訊
一種全景視網(wǎng)膜影像檢查設(shè)備能夠進(jìn)行全角度視網(wǎng)膜影像檢查,只需不到1秒鐘的時(shí)間,而無需進(jìn)行瞳孔擴(kuò)張。 P200MA是由Optos公司(Dunfermline, Scotland)制造的,由掃描激光系統(tǒng)組成,將兩個(gè)低能量激光整合成一束,投射到患者視網(wǎng)膜,通過一個(gè)200o掃描角進(jìn)行操作。從視網(wǎng)膜反射的光束然后回到掃描系統(tǒng),通過高度敏感的光-二極管轉(zhuǎn)換為電脈沖。這些脈沖然后轉(zhuǎn)換為數(shù)字并變換格式形成數(shù)字的廣域視網(wǎng)膜影像。該掃描激光檢眼鏡利用影像系統(tǒng)形成患者眼睛的“虛擬掃描點(diǎn)”。該設(shè)備已經(jīng)獲得了美國(guó)食品藥品管理局的批準(zhǔn)。 The P200MA, manufactured by Optos (Dunfermline, Scotland), is composed of a scanning laser system that combines two low-powered lasers into a single beam that is then projected onto the patient’s retina and manipulated through a 200o scan angle. Light reflected from the retina is returned through the scanning system and converted to electrical impulses by highly sensitive photo-diodes. These impulses are in turn digitized and formatted to create a digital wide-field image of the retina. The scanning laser ophthalmoscope device then uses the imaging system to create a “virtual scanning point” inside the patient’s eye. The device has been approved by the U.S. Food and Drug Administration (FDA). 本文關(guān)鍵字:
