A vein contrast enhancer (VCE) has been constructed to make vein access easier by capturing an infrared image of veins, enhancing the contrast using software, and projecting the vein image back onto the skin. The VCE also uses software to align the projected image with the vein to 0.06 mm. Clinical evaluation of earlier monitor-based vein enhancement test systems has demonstrated the clinical utility of the infrared imaging technology used in the VCE.
一种静脉造影增强器（VCE）已被制造出来，它通过捕捉静脉的红外图像、利用软件增强对比度并将静脉图像投射回皮肤，从而使静脉穿刺更容易。VCE还使用软件将投射图像与静脉对齐至0.06毫米。对早期基于显示器的静脉增强测试系统的临床评估已经证明了VCE中使用的红外成像技术的临床实用性。
