    1. Dynamic analysis of mental sweating by optical coherence tomography

      Dynamic analysis of mental sweating by optical coherence tomography
      In the dynamic OCT of mental sweating, we have found internal mental sweating without ejection of excess sweat from the spiral lumen to the skin surface. Internal sweating occurs more often in the case where mental stress is applied to a volunteer, and it is more useful for evaluation of activity of the sympathetic nerve. Furthermore, the MIP imaging has been proposed for quick 3-D imaging of the spiral lumen of sweat glands. Using time-sequential MIP images with the frame spacing as short as 1.4 sec, several sweat glands can be tracked simultaneously to quantify sweating stimulated by a ...

    2. Maximum intensity projection imaging for dynamic analysis of mental sweating by optical coherence tomography

      A novel 3-D image construction method with maximum intensity projection (MIP) of B-mode OCT images is proposed for in vivo dynamic analysis of mental sweating on human fingertips. Time-sequential MIP-OCT images with the frame spacing as short as 1.4 sec provide us quantitative analysis of the sweati ... [Proc. SPIE 7168, 71682D (2009)] published Fri Feb 20, 2009.

    3. Maximum-Intensity-Projection Imaging for Dynamic Analysis of Mental Sweating by Optical Coherence Tomography

      Authors: Hiroyuki Saigusa, Yoshihiro Ueda, Akihiro Yamada, Masato Ohmi, Makoto Ohnishi, Mitsuo Kuwabara, and Masamitsu HarunaOptical coherence tomography (OCT) shows great potential for microscopic observation of human sweating dynamics. It should be a key technology in the development of new techniques for the study of dynamic physiology. In this study, the dynamic motion of eccrin sweat glands is visualized by three-dimensional (3-D) OCT imaging, and a novel 3-D image construction method, using maximum intensity projection (MIP) of B-mode OCT images, is proposed for in vivo dynamic analysis of mental sweating on human fingertips. Time-sequential MIP-OCT images with a frame spacing ...

    4. Maximum-intensity-projection images for dynamic analysis of mental sweating by optical coherence tomography

      Hiroyuki Saigusa, Yoshihiro Ueda, Akihiro Yamada et al. We demonstrate a novel 3-D image construction method with maximum intensity projection (MIP) of B-mode images obtained by the swept-source OCT. The time-sequential MIP images with a frame spacing of only 0.7 sec are obtained to make dynamic analysis of mental sweating on human fingertips. ... [Proc.
