Arthritis Imager™ |
|
Product Information
|
A sensor-based imaging system can rapidly and reliably measure changes in arthritis.
The Arthritis Imager™ system uses a combination of thermal and 3D imaging to produce surface
images of the joint by measuring the warmth (thermal) and swelling (3D) of wrist and
metacarpophalangeal (MCP or “knuckles”) joints in a reproducible manner for patients diagnosed
with active arthritis. The Imager offers rapid and quantification of the state of the inflammed
joint.

Why It Works
|
Arthritis causes inflammation in the joints that result in both swelling and elevated temperature relative to the
surrounding tissue. The Arthritis Imager makes a precise measurement of both, utilizing 3D and thermal images and
allows comparison of these images from one session to the next.
Cartesia Dx’s first product, Arthritis Imager™, addresses the lack of objective, quantifiable diagnosis and
monitoring of RA. The system combines well established technologies with a proprietary approach to create a new
diagnostic metric that allows healthcare professionals to objectively quantify the progression of RA.

System Benefits
|
 |
- Provides objective, documented measures of change
- Early detection of disease leads to better outcome
- Enables improved disease management
- Increases patient throughput – increasing revenue
|
|
|
X-ray, MRI, and Ultrasound have been evaluated, but have significant deficiencies:
|
|
|
- X-ray has proven not to be effective in detecting early and small changes in the disease.
- MRI, while able to detect early inflammation, is time-intensive and expensive and offers no standard validated methods to grade changes in arthritis.
- Ultrasound exhibits a high degree of variability between users, is time-consuming and cannot cover the entire region of interest being evaluated.
