What to Expect from Your NaviCam Small Bowel Study

 

With the NaviCam® SB System, getting answers about your digestive health is simple and stress-free. You’ll swallow a vitamin-sized capsule that travels naturally through your GI tract, capturing thousands of images. A comfortable belt worn around your torso records the data while you go about your day.

​

After about eight hours, you’ll return the recorder to your doctor, who will review the video—enhanced by ProScan™ AI—for an accurate and timely diagnosis. No sedation, no hospital stay—just a smarter, patient-friendly way to understand your health.
