Video endoscopic camera/software from Kettex Development


25.10.2021: As soon as the Czech national ENT conference was finished we have to prepare for the ENT conference in Mannheim. Join us!

7-9.10.2021: We will exhibit at Czech/Slovak Days of Phoniatry in Bratislava.

8-11.9.2021: We will exhibit at Slovak National ENT conference in Zilina. Meet us there!

15.8.2021: We are proud to announce a new distributor of our devices in Poland - EUMed Sp.z o.o.

14.6.2021: A small step for a doctor, but a big step for our company. We sold our first camera in Belgium.

10.2.2021: We release a new camera KX-01-OR for operation theatre. It complies with MDR, of course.

We are producers of USB endoscopic cameras and software. Our cameras provide superb images and our software provides unique features. The cameras and software comply with MDR.

These features distinguish us from competitors.

Vessels highlighting (ExView)

From light source wavelength we are able to suggest an appropriate RGB filter that highlights blood-vessels in the tissue. This way the doctor can easily distinguish the common blood-vessels structure from the one which was created by precancerosis or tumor.

TrueHDR imaging

Tissue near the endoscope can be over-illuminated while the distant part can be under-illuminated. This is because the amount of light decrease rapidly with the distance from endoscope tip. We can compensate it by capturing several images with different exposure times and fusing it into the single picture. We are able to do it in real-time on live image.

A Sight Tracking AEXP

There is another solution to the problem of scenes with hight dynamic range. The solution is to follow the doctor's direction of view. The area your doctor is looking at will then be perfectly illuminated by the application.

Fibroscopic grid correction

Our software is able to remove fibroscopic grid and preserve all the data at the image. We do it on live stream at 25 fps, so the image remains fluent.

Noise reduction

When doctor observes distant places or if he/she has not very powerfull light source the image contains some additional noise, because autoexposure increase camera gain (ISO) automatically to preserve the overall image brightness. Noise is disturbing and makes the image unpleasant. We have developed real-time image denoising algorithm, that suppress noise while preserves image details. The following example is not from real patient's examination (the light brightness was artificialy set only to 3% of the brightness maxima), but shows the denoising effect well.

Structure highlighting

Struct is the software filter highlighting structures of the tissue.
