Ikematsu H, Takara Y, Nishihara K, Kano Y, Owaki Y, Okamoto R, et al.
J Gastroenterol . 2024 Oct; 60(1):77-85. PMID: 39441401
Background: Fecal immunochemical tests are commonly performed for colorectal cancer screening. Instant fecal occult blood measurement in toilet bowel movements would improve convenience. Hyperspectral imaging (HSI) enables the nondestructive evaluation...

Takamatsu T, Fukushima R, Sato K, Umezawa M, Yokota H, Soga K, et al.
Opt Express . 2024 Jun; 32(9):16090-16102. PMID: 38859246
In this study, we developed a rigid-scope system that can perform hyperspectral imaging (HSI) between visible and 1600 nm wavelengths using a supercontinuum light source and an acousto-optic tunable filter...

Takamatsu T, Tanaka H, Yano T
Sensors (Basel) . 2024 Mar; 24(5). PMID: 38475023
The drug efficacy evaluation of tumor-selective photosensitive substances was expected to be enabled by imaging the fluorescence intensity in the tumor area. However, fluorescence observation is difficult during treatments that...

Mitsui T, Mori A, Takamatsu T, Kadota T, Sato K, Fukushima R, et al.
J Biomed Opt . 2023 Aug; 28(8):086001. PMID: 37614567
Significance: Determining the extent of gastric cancer (GC) is necessary for evaluating the gastrectomy margin for GC. Additionally, determining the extent of the GC that is not exposed to the...

Takamatsu T, Endo Y, Fukushima R, Yasue T, Shinmura K, Ikematsu H, et al.
Sci Rep . 2023 Jun; 13(1):10494. PMID: 37380716
The insertion of conventional colonoscopes can sometimes cause patients to experience pain during the procedure owing to the stretching of the mesentery. In this study, a prototype of a robotic...

Takamatsu T, Kitagawa Y, Akimoto K, Iwanami R, Endo Y, Takashima K, et al.
Sensors (Basel) . 2021 Apr; 21(8). PMID: 33918935
In this study, a laparoscopic imaging device and a light source able to select wavelengths by bandpass filters were developed to perform multispectral imaging (MSI) using over 1000 nm near-infrared...

Sato D, Takamatsu T, Umezawa M, Kitagawa Y, Maeda K, Hosokawa N, et al.
Sci Rep . 2020 Dec; 10(1):21852. PMID: 33318595
The diagnosis of gastrointestinal stromal tumor (GIST) using conventional endoscopy is difficult because submucosal tumor (SMT) lesions like GIST are covered by a mucosal layer. Near-infrared hyperspectral imaging (NIR-HSI) can...
