RESEARCH & DEVELOPMENT
The impact of technology on society is increasing and the pace of evolution is accelerating. Canon is committed to contributing to mankind and society by responding to the changing times and continually generating cutting-edge innovations.
HEALTHCARE OPTICS RESEARCH LABORATORY
Established on the foundation of Canon U.S.A.’s corporate philosophy, Kyosei, in November 2012, Canon entered into collaborative research agreements with Massachusetts General Hospital, and Brigham and Women’s Hospital to develop biomedical optical imaging and medical robotics technologies.
This collaboration lead to the opening of the Healthcare Optics Research Laboratory in Cambridge, Massachusetts in June 2013.
The research laboratory is approximately 13,600 square feet and is the home of skilled employees dedicated to developing biomedical optical imaging and medical robotics technologies with the ultimate goal of bringing medical devices to market for a variety of applications.
The areas that the technology will address include:
- Image Guided Therapy
- Miniature Endoscopic Imaging
- Functional Imaging
Healthcare Optics Research Laboratory, Canon U.S.A. is working in conjunction with its parent company, Canon Inc.
Image guided therapies provide better outcome by improving diagnostic accuracy and targeted treatment for diseased tissue. Research in image guided therapy includes, a robotic device for guidance of percutaneous interventions of abdominal and thoracic cavity, and a combination of targeted agent delivery and image guided platform to improve treatment efficacy. The overall purpose is to develop platform technologies for broader applications. One application, among many others, for our robotic device is image-guided cryotherapy of kidney cancer.

Overall objective is to expand the applications of minimally invasive diagnostic and therapeutic endoscopy to areas currently considered unreachable. This project utilizes Canon's strong expertise in innovative imaging and optics solutions and is focused on developing an ultra thin, human hair size, high resolution endoscope that will produce three dimensional images, while enabling direct visualization of 'hard to see' anatomies.
Additionally, a parallel project is focusing on the ability of an endoscope to maneuver through small anatomical spaces by developing robotic multipoint motion. This technology allows to control and navigate, on demand, an endoscope tethered to a console for application in neurosurgery, orthopedics, and laryngoscopyi ii.

Despite advances in imaging technologies, coronary artery disease is still the most common cause of death globally. A number of factors are associated with acute coronary event and understanding its complex relationship with vulnerable plaque could play a key role in managing patient population at risk. Canon efforts are geared towards developing an advanced imaging system and arterial catheter capable of simultaneously obtaining high quality information that enable accurate diagnosis and longitudinal management of disease. Basic principle relies on expanding the scope of imaging from three dimensional structural information to molecular and mechanical properties of coronary plaques. Different methods of understanding both, tissue molecular and mechanical properties are currently being investigated.
Additional research efforts are focused on functional imaging of brain for better understanding of physiological parameters impacted due to an injury or medical treatment such as anesthesia. Technical development includes non-invasive bed side quantification of blood flow and oxygenation to cerebral tissue.

How do we leverage Big Data to make cameras smarter?
Open world computer vision is the combination of the state-of-the-art artificial intelligence algorithms with information inferred from databases. This can improve the performance of object identification and classification, which can be applied, for example, to network camera solutions.
The goal of the computational imaging research is to come with theoretical and experimental methods to explore unconventional ways to combine digital imaging capture and novel image processing techniques in order to understand better the nature of scenes we capture and provide proof-of-concept and prototyping for core technologies that enables improvement of imaging capabilities and performance. This work is centered on illumination-based physical sensing in which research is conducted on technologies that can be used to measure arbitrary shapes and materials in 3-D.
