Photoacoustic imaging with a synthetic aperture focusing technique(SAFT) is an effective method to improve the lateral resolution for out-of-focus regions in scanning microscopy systems, which commonly require a decent motorized scanning stage for a lateral scan of a transducer to obtain a cross-sectional image. In this study, we propose and test a photoacoustic imaging system with a scanning mirror-based SAFT(SM-SAFT) for simple and fast data acquisition, without the need for a physical scan of the transducer. Photoacoustic images of hair phantoms acquired by SM-SAFT are demonstrated, serving as a proof-of-concept experiment to show the feasibility and potential of the proposed approach.

目的 探讨KTP激光泪道成形术与泪道探通术治疗新生儿泪囊炎的临床疗效。方法新生儿泪囊炎100例(109眼)。随机分为两组,激光组50例(57眼),探通组50例(52眼),随访6~12个月。结果激光组57眼中,一次治愈率为98.24%;探通组52眼中,一次治愈率为82.69%(P〈0.05)。结论 KTP激光泪道成形治疗新生儿泪囊炎较泪道探通术疗效好。

对于识字的人来说,最大的幸福莫过于读书。宋人尤袤有云:饥读之以当肉;寒读之以当裘;孤寂而读之,以当友朋;幽忧而读之,以当金石琴瑟也。可谓得读书之真意。可惜后来人的读书观念渐渐起了变化,读书被当作一项功利性的手段而存在。  对手读书人来说,最好的读书时光莫过于夜晚。“青灯有味是儿时”是南宋大诗人陆放翁老先生追念儿时对灯读书的况味,千载读之仍然觉得亲切温馨。记得自己在少年时常常喜欢趴在被窝里看书,那时
