Breast measurement apparatus
Toshihiko Suzuki,Yutaka Yamashita,Yukio Ueda,Etsuko Yamaki,Daisuke Yamashita,Kenji Yoshimoto,Harumi Sakahara,Hiroyuki Ogura,Hatsuko Nasu +8 more
TL;DR: A breast measurement apparatus as mentioned in this paper comprises a receptacle for surrounding a breast, a plurality of optical fibers for irradiating the breast with examination light and detecting transmitted scattered light from the breast, an inner image generation unit for generating an optical CT image concerning the breast according to a detection signal of the transmitted scattered signals, an ultrasonic probe, arranged so as to face the inside of the receptacle, for scanning the breast and receiving a reflected wave from the exposed breast, and an image generator for generating a mammogram concerning the mammogram according to the reflected wave.

Hemodynamic measurements in deep brain tissues of humans by near-infrared time-resolved spectroscopy
Hiroaki Suzuki,Motoki Oda,Etsuko Yamaki,Toshihiko Suzuki,Daisuke Yamashita,Kenji Yoshimoto,Shu Homma,Yutaka Yamashita +7 more
TL;DR: A potential application of this TRS system in examining deep brain tissues of humans is demonstrated as the level of hemoglobin and the SO2 were strongly correlated between the human head measurements in transmittance mode and the forehead measurements in the reflectance mode, respectively.
Patent
Method and device for measuring scattering-absorption body
Etsuko Yamaki,Yutaka Yamashita,Motoki Oda,Hiroaki Suzuki,Toshihiko Suzuki,Hiroshi Watanabe,Shunsaku Koga +6 more
TL;DR: In this paper, a temporal profile of the light intensity of the detected light is acquired, and on the basis of the temporal profile, an mean optical path length of light in the interior of the scattering-absorption body and information relating to the amount of substance to be measured in a region of the body is calculated.
Patent
Mammographic measuring apparatus
Toshihiko Suzuki,Yutaka Yamashita,Yukio Ueda,Etsuko Yamaki,Daisuke Yamashita,Kenji Yoshimoto,Harumi Sakahara,Hiroyuki Ogura,Hatsuko Nasu +8 more
TL;DR: In this article, a mammographic measuring apparatus which is capable of acquiring an ultrasonic image and an optical CT image under the same measurement condition is presented. But, the mammographic measurement apparatus is not suitable for the acquisition of both images and CT images.
Journal ArticleDOI
Measurement of maternal cerebral tissue hemoglobin on near-infrared time-resolved spectroscopy in the peripartum period.
Kazunao Suzuki,Hiroaki Itoh,Mari Mukai,Kaori Yamazaki,Toshiyuki Uchida,Hideki Maeda,Motoki Oda,Etsuko Yamaki,Hiroaki Suzuki,Naohiro Kanayama +9 more
TL;DR: To measure cerebral tissue hemoglobin in uncomplicated and complicated pregnant women during the peripartum period to find out if there are any differences in the levels ofoglobin in the brain during this period of pregnancy.
