| 4 | 激光牙科为商业化而奋斗显示文摘钻牙期间透入人体的中、低频震动部分已为高频金刚钻出现而减轻,但只有激光钻孔技术才可能完全消除研磨方式引起的耳朵和脊柱抖动。主要来自欧洲的一批牙科和内科医生在91年洛杉矶举行的OE/Laser’91会议上对此问题进行了报告。他们对激光去除龋齿和提供更接近牙质、珐琅质的填料怀有巨大兴趣。在牙科学中,对激光钻牙问题存在一些争论,但目前的探讨集中在未预测的实验观测上。首先,在450nm激光波长范围内。 | R.Weiss 友清 | 1992 | 国外激光1992，，3： | 0 |
| 5 | Real-Time High-Resolution MRI Endoscopy at up to 10 Frames per Second显示文摘Objective.Atherosclerosis is a leading cause of mortality and morbidity.Optical endoscopy,ultrasound,and X-ray offer minimally invasive imaging assessments but have limited sensitivity for characterizing disease and therapeutic response.Magnetic resonance imaging(MRI)endoscopy is a newer idea employing tiny catheter-mounted detectors connected to the MRI scanner.It can see through vessel walls and provide soft-tissue sensitivity,but its slow imaging speed limits practical applications.Our goal is highresolution MRI endoscopy with real-time imaging speeds comparable to existing modalities.Methods.Intravascular(3 mm)transmit-receive MRI endoscopes were fabricated for highly undersampled radial-projection MRI in a clinical 3-tesla MRI scanner.Iterative nonlinear reconstruction was accelerated using graphics processor units connected via a single ethernet cable to achieve true real-time endoscopy visualization at the scanner.MRI endoscopy was performed at 6-10 frames/sec and 200-300μm resolution in human arterial specimens and porcine vessels ex vivo and in vivo and compared with fully sampled 0.3 frames/sec and three-dimensional reference scans using mutual information(MI)and structural similarity(3-SSIM)indices.Results.High-speed MRI endoscopy at 6-10 frames/sec was consistent with fully sampled MRI endoscopy and histology,with feasibility demonstrated in vivo in a large animal model.A 20-30-fold speed-up vs.0.3 frames/sec reference scans came at a cost of~7%in MI and~45%in 3-SSIM,with reduced motion sensitivity.Conclusion.High-resolution MRI endoscopy can now be performed at frame rates comparable to those of X-ray and optical endoscopy and could provide an alternative to existing modalities,with MRI’s advantages of soft-tissue sensitivity and lack of ionizing radiation. | Xiaoyang Liu Parag Karmarkar Dirk Voit Jens Frahm Clifford R.Weiss Dara L.Kraitchman Paul A.Bottomley | 2021 | Biomedical Engineering Frontiers2021，2，1： | 0 |
