3D Shape Reconstruction of 3D Printed Transparent Microscopic Objects from Multiple Photographic Images Using Ultraviolet Illumination

Autor: Keishi Koyama, Masayuki Takakura, Taichi Furukawa, Shoji Maruo

Publikováno v: Micromachines, Vol 9, Iss 6, p 261 (2018)

We propose and demonstrate a simple, low-cost, three-dimensional (3D) shape acquisition method for transparent 3D printed microscopic objects. Our method uses ultraviolet (UV) illumination to obtain high-contrast silhouette images of transparent 3D p

Complete omission of second-look endoscopy after gastric endoscopic submucosal dissection in real-world practice

Autor: Kohei Funasaka, Hyuga Yamada, Noriyuki Horiguchi, Hayato Osaki, Dai Yoshida, Tsuyoshi Terada, Keishi Koyama, Masaaki Okubo, Tomomitsu Tahara, Mitsuo Nagasaka, Yoshihito Nakagawa, Tomoyuki Shibata, Naoki Ohmiya

Publikováno v: Medicine. 101(28)

Gastric endoscopic submucosal dissection (ESD) is increasingly performed in patients receiving antithrombotic therapy. Second-look endoscopy (SLE) has been performed empirically in several clinical settings. We investigated whether SLE omission was a
