Point-of-care testing is a rapidly evolving yet complex field. As your POCT program grows, take the time to understand the regulations, as they are important to ensuring patient safety. The regualtions established CLIA are designed to ensure consistent and reliable laboratory results that can accurately impact patient care. When beginning your look into POCY, first identify what labs can direct...

purpose: to determine the effect of using rigid gas permeable (rgp) contact lenses in improvement of involuntary eye movements and visual functions in hyperopic astigmatism patients with congenital nystagmus. methods: this prospective interventional case series study was conducted on patients with congenital nystagmus and hyperopia equal or more than +0.5 d and astigmatism more than -1 d, who w...

اساس سیستم‌های تصویربرداری ایکس پس­پراکنده، پرتوهای بازگشتی هستند که در صنعت و بازرسی دارای کاربرد‌های بسیاری می‌باشند. این تصاویر برخلاف روش عبوری، مواد آلی با عدد اتمی پایین مانند مخدر منفجره پراکندگی فوتون بالا، واضح‌تر دیده می‌شوند. به علت چندگانه فوتونی معمولاً مات­شدگی دارند. پردازش خروجی می‌تواند بهبود کنتراست تشخیص کمک کند. تحقیق از وردش برای استفاده شده پرتونگاره‌های فانتوم‌هایی ارزیابی...

Combining input from multiple senses is essential for successfully mastering many real-world situations. While several studies demonstrate that the presentation of a simultaneous sound can enhance visual detection performance or increase the perceived luminance of a dim light, the origin of these effect remains disputed. The suggestions range from early multisensory integration to changes in re...

This paper presents a novel image enhancement algorithm using a multilevel windowed inverse sigmoid (MWIS) function for rendering images captured under extremely non uniform lighting conditions. MWIS based image enhancement is a combination of three processes viz. adaptive intensity enhancement, contrast enhancement and color restoration. Adaptive intensity enhancement uses the non linear trans...

We present terahertz images of 10 μm thick histopathologic sections obtained in reflection geometry with a time-domain spectrometer, and demonstrate improved contrast for sections measured in paraffin with water. Automated segmentation is applied to the complex refractive index data to generate clustered terahertz images distinguishing cancer from healthy tissues. The degree of classification o...
