Non-invasive imaging system for early detection of periodontal disease in cats
A novel, non-invasive imaging technology for cats that offers high-sensitivity detection of periodontal disease, improving diagnosis and treatment effectiveness while reducing invasive procedures and radiation exposure.
Overview
The non-invasive imaging system for detecting periodontal disease in cats offers a revolutionary approach to feline dental care. By utilizing advanced thermophotonic imaging, this technology provides high-sensitivity detection of early dental issues, significantly improving diagnosis and treatment outcomes. Unlike traditional methods such as dental X-rays, which can be harmful and lack early detection sensitivity, this system is both user-friendly and safe, promoting better oral health and quality of life for cats.
Technical specifications
The core technology employs laser pulses that are directed onto the tooth surface, with infrared emissions captured by a camera detector. This method is highly sensitive to changes in tooth enamel composition, making it ideal for identifying early signs of enamel breakage, fractures, and resorptive lesions. The system is designed to be non-invasive and radiation-free. Future enhancements include optimizing laser parameters and integrating a portable laser diode source for clinical use, ensuring high contrast and effective volumetric imaging.
Technology readiness level
Currently at Technology Readiness Level 5, this system has been validated in pre-clinical tests on extracted cat teeth. It is poised for in-situ testing in collaboration with veterinary clinics, and regulatory approvals are being pursued for widespread adoption in the USA and EU.
