静脉穿刺是通常在医院进行的医疗实践。然而，这是一个困难的过程，因为发生了许多穿刺失败，有时医疗事故，如神经损伤和血管损伤的报告。这是由于难以在视觉上识别血管造成的。虽然血管的深度信息也很重要，但临床实践中现有的系统只能通过二维图像来可视化血管。在本文中，估计的三维位置的血管，我们提出了系统的基础上重新聚焦使用光场成像。该方法可以在每个深度处获得使用近红外光强调的血管的横截面信息。最后通过实验验证了该方法的有效性。
Venipuncture is a medical practice which is ordinarily performed in hospital. However, it is a difficult procedure as the occurrence of many failure of the puncture and sometimes medical accidents such as nerve damage and blood vessel damage are reported. This is caused by the difficulty of visually identification of the blood vessel. Although the depth information of the blood vessel is also important, the existing system in clinical practice can visualize vessels only by two dimensional images. In this paper, to estimate the three dimensional position of the blood vessel, we propose the system based on refocusing using light field imaging. This method can obtain cross-sectional information of blood vessel emphasized using near infrared light at each depth. We finally confirm the validity of the proposed method by experiments.
