Ultra-sensitive X-ray sensors for diagnostic imaging

Differentiating unhealthy tissue from healthy tissue just got easier.

Kairos Sensors is dedicated to making better x-ray cameras for medical imaging so that you can create more memories with the ones you love. The way we do that is by creating ultra-sensitive sensors that provide vastly improved mammography images with superior diagnostic accuracy.

We leverage a proprietary industry-leading X-ray sensor capable of generating images that contain superior diagnostic information that results in better patient outcomes. Our ultra-sensitive detector provides the solution to existing medical imaging systems not being able to differentiate unhealthy tissue from healthy tissue.

In Greek mythology, the word Kairos means “the right, critical, or opportune moment.” We call ourselves Kairos Sensors because we believe the time is right to increase the quality of images taken with traditional mammogram imaging sensor materials and decrease the chance of inaccurate results.

Bettering patient outcomes

When a second screening or biopsy is needed, it not only brings stress to women and their families, it also comes with a financial cost. Secondary screenings cost about $4 billion each year in the US and are one reason insurance companies charge higher premiums.

Kairos Sensors innovative detector will provide superior medical images that are currently unavailable to Radiologists and Clinicians at the moment. Our ultra-sensitive APeX™ sensors are being developed by industry leaders and researchers to vastly improve the ability to differentiate unhealthy tissue from healthy tissue.

Decreasing false positives and negatives, increasing accuracy

Current Problem: Mammography technology used in hospitals and clinics today cannot efficiently distinguish between healthy tissue and cancerous tissue. This is because current state-of-the-art X-ray sensors lack grayscale sensitivity to differentiate similar density tissues.

Currently 3D-mammography detectors have a low signal-to-noise ratio because relatively few photons are incident per pixel for each image slice that make up the entire breast volume dataset. This means that the images produced are low quality with inadequate diagnostic information. As a result, there are prevalent false positives/negatives and the need for secondary screenings because sensor materials in these devices are not sensitive enough to determine cancerous tissue accurately.

The Solution

Our innovative detector uses perovskite-based materials to create a signal-to-noise ratio that is 350% higher than what current mammography imaging is capable of.

Our perovskite-based APeX™ sensors are ultra-sensitive and can distinguish the difference in similar density materials. The combination of materials we use amplifies the readout signal per pixel which results in higher contrast resolution in grayscale images. This allows physicians to analyze images and better determine potential unhealthy tissue in breast exams. Kairos Sensors’ detector will help to dramatically cut down on second screenings for patients, and provides a way for physicians to always have access to updated equipment.

Current mammography equipment costs around $500,000. Not only does this price point make the latest technology not very accessible to rural communities, but the equipment also cannot be easily upgraded. This means that outdated technology remains in place well past its due date instead of patients being able to access the latest technology.

Kairos Sensors’ patent pending APeX™ sensor for mammography equipment is far less expensive and also allows the detector on the existing mammogram camera to be upgraded every year. Making the latest updates available year-after-year means that physicians and patients always have the best technology available for better patient outcomes.

Kairos Sensors continues to invest in systems that increase the speed at which experimental tests can be built to test hypotheses and analyze the results. Once we are sure that we understand the needs of our customers, we can then utilize rapid product development to optimize the build, measure, and learn feedback loop. This allows us to eliminate the things that don’t work well fast, and double down on our efforts for the things that do.
