Thanks to continual advances and miniaturization, today’s sophisticated medical cameras can see where our eyes cannot.
Medical video cameras enable surgeons and clinical staff to capture colour images during microscopy and open surgical procedures. Surgeons in the OR can benefit from HD image quality in a compact camera head that integrates efficiently with surgical microscopes and slit lamp systems.
Of utmost importance, all medical cameras introduced into the body must be strictly clinically proven for biocompatibility and safety in accordance with regulatory requirements. Illumination and irrigation features are often integrated with camera hardware to assure uninterrupted delivery of clinical images.


Following is an overview of how some medical cameras and their imaging components work:

* Lensless, ultra-miniature CMOS computational imagers and image sensors employ special optical base gratings integrated with Complementary metal–oxide–semiconductor (CMOS) photodetectors. Because such imagers have no lens, they are ultra-miniatureand have large effective depth of field (1mm to infinity). This tiny size is highly suitable for endoscopy and medical sensing, as well as medical camera inspection applications. Additionally these high-performance imagers are inexpensive making them ideal for integration in cost-effective, disposable / single-use medical devices.

* Miniature cameras:
Fiber-based (though thin, optical fibers are breakable and therefore can’t access many spots. Can be costly – the smaller the diameter the higher the price
Camera-at-tip solution integrated in flexible or rigid endoscopes
Embedded within medical capsules (“pill-cams”) a disposable medical camera inspection / diagnostic tool with 1-2 video cameras with restricted battery life; transmitted images are processed and viewed later, not in real-time, via specialized software

* 3D medical imaging cameras uses laser triangulation, structured light or stereoscopy for capturing and rendering 3D information; applications can include 3D-toothscanning for dental restorations, simulations of cosmetic surgery

* Infrared imaging uses various wavelengths to visualize water content, temperature or chemical components of tissue which cannot be detected with conventional medical inspection cameras.
