Introduced MEMS technology to Canon and has a wealth of experience in practical application of the technology in inkjet printer etc. Has a wealth of experience in industry-academia collaboration, including representing Canon in joint development of Kyoto University and Canon in the MEXT program, “Innovative Techno-hub for Integrated Medical Bio-imaging”.
With the arrival of the super-aging society, there has been a rapid increase in morbidity and the number of persons requiring nursing care, and there is widespread concern in the general public regarding illness and nursing care. In this situation, there is a need to enable people to continue working while preserving their health and beauty. There is also heightened concern about food safety, product quality and other issues, and achieving safety and security in people’s lives is an important issue facing society. The goal of this program is to develop real-time 3D visualization technology that can image blood vessels to enable early diagnosis of disease, preventive medicine and maintenance of health and beauty. This visualization technology will contribute to extending “healthy life expectancy”. In addition, by imaging of changes in physical properties in products and its materials, this technology will contribute to increasing the reliability of products, structures and food safety and improving the quality of Japanese products, thereby helping to strengthen competitiveness.
- Integrating state-of-the-art laser and ultrasound technologies perform real-time 3D visualization of changes in properties and functions (workings) inside the human body and substances, non-invasively and non-destructively.
- The new visualization technology brings out noninvasive 3D imaging of vessel network and blood condition to enable early diagnosis and estimation of physical depression and will also enable non-destructive inspection of the internal structure and changes in the properties of objects.
The Challenges for the PM and the Impact of Success
Overview and background
- With the arrival of the super-aging society, there has been a rapid increase in morbidity and the number of persons requiring nursing care, and there is widespread concern in the general public regarding illness and nursing care. In this situation, there is a need to enable people to continue working while preserving their health and beauty.
There is also heightened concern about food safety, product quality and other issues, and achieving safety and security in people's lives is an important issue facing society.
- The objective is to develop a new visualization technology that can image the state of the human body and objects whose insides are not visible, non-invasively and non-destructively, to enable early diagnosis of disease and maintenance of health, as well as quality examinations of changes of substance in order to contribute to safety and security.
Impact on industry and society in the event of achievement
- A new noninvasive modality for very early diagnosis is created. Early detection of underlying damage to skin aging, joint disease and lifestyle related diseases becomes possible. The technology will create a new medical imaging industry, comparable to CT scanner and MRI, new beauty industry and healthcare industry due to noninvasive. The technology also conducts new quality inspection method to enhance international competitiveness of material industry and food industry.

- (4) Presentation of applications in the measurement industry, such as quality inspections, safety inspections, non-destructive inspections etc.
- The domestic production of lasers for medical use will be achieved.
- There are no verification of clinical value for its blood vessel imaging, and this requires comparative studies of existing diagnostic methods.
Overall R&D Program Structure Created by the PM
The program will consist of the development of three base technologies, development of realtime visualization system, and demonstration of value in order to verify usefulness. The real-time visualization systems to be developed will comprise a wide-field visualization system and a microvisualization system with high resolution approaching that of a microscope. These systems will perform real-time 3D imaging in the range from micrometer-size to millimeter-size.
- Visualization technology: High resolution imaging will be researched, analyzing the generating mechanism of photoacoustic signals and making a database of properties in order to optimize laser wavelength and sensor configuration.
- Tunable laser technology: Electronically tunable lasers with ultra-wide range of wavelength, infrared tunable laser for human body and a range of mid-infrared tunable laser for substances, will be developed and achieved with high durability and compact.
- Ultrasound sensor technology: A sensor that can achieve more than double the broadband capacity of conventional sensors will be developed through competition between a piezoelectric ultrasound sensor and a capacitive ultrasound sensor (CMUT). Following selection, a 2D ultrasonic sensor array designed for real-time detection will be achieved.
- Wide-field visualization system: High-speed signal processing and 3D imaging technologies will be completed and a visualization system, installed with laser and ultrasound sensor, for realtime 3D imaging will be developed.
- Micro-visualization system: A basic system will be designed based on high-frequency ultrasound technology and a micro visualization system will be developed in addition to technologies developed for wide-field visualization. The system can image capillary vessels in the skin.
- Demonstration of value: The visualization systems will be provided to multiple medical research institutions to develop diagnostic methods and skin function evaluation methods. Diagnostic and evaluation indexes will be shown through image analysis, and a risk prediction model of disease will be proposed through “big data” analysis.
