New Medical Light Source using NTT's Communication Laser Technology

2013/01/31

In a joint partnership, NTT Advance Technology Corp. (hereinafter: NTT-AT; head office: Shinjuku-ku, Tokyo; President and CEO: Takashi Hanazawa) and Hamamatsu Photonics K.K. (head office: Hamamatsu-shi, Shizuoka; President and CEO: Akira Hiruma) will start selling a 1.3-μm-band wavelength swept light source for use in optical coherence tomography (OCT) on February 1. OCT is a non-invasive in vivo imaging technique that is widely used in clinical applications.

 

NTT-AT has developed this product using the same technology employed in the manufacture of an electro-optic crystal called KTN (potassium tantalate niobate: KTa1-xNbxO3) developed for use in telecommunications by Nippon Telegraph and Telephone Corporation (hereinafter: NTT; head office: Chiyoda-ku, Tokyo; President and CEO: Hiroo Unoura). The product is a marriage between this technology and high-speed variable wavelength laser technology that uses the crystal. Achieving a wavelength sweep speed of 200 kHz, the world’s fastest (double that of conventional products), this light source will speed up OCT-based examinations, significantly reducing the physical impact on patients. NTT-AT manufactures this product and will market it jointly with Hamamatsu Photonics K.K., a company which has significant involvement in the manufacture and sale of medical devices and has a global sales network. The two companies will work together in selling wavelength swept light sources for OCT, and undertake joint development in order to augment their product portfolios and facilitate mass production, thereby expanding their presence in the medical device market.

 

This light source will be on display in the booths of the two companies at the exhibition that will be held in conjunction with SPIE Photonics West 2013 in San Francisco from February 2 to 7.
