With many companies offering imaging towers for endoscopy, competition for the latest and greatest imaging technology is moving at a fevered pace. Camera resolution is increasing almost as fast as the cost of the camera towers. And the truth is, image quality has surpassed our ability to discern the subtle differences between the top systems, making a lot of ballyhooed n-th degree improvements an expensive waste.
While the resolution wars rage between the largest medical imaging companies, BioVision has taken a different and more practical approach. Although camera characteristics play a big role in image quality, the real determining factor is the scope. This fact goes relatively unnoticed when comparing the standard laparoscopes used in general surgery, with outer diameters (OD) in the 4 to 10mm range. With a 10mm glass lens laparoscope, resolution is outstanding, but with a 1mm fiberscope, the resolution is 1/10 that of the larger scopes. This basic difference in technology and construction actually works against you when trying to use big high-resolution towers with very small scopes. Image size, illumination distribution and concentricity play a much bigger role with small scopes than with larger glass scopes. A 4 million pixel hi-res camera will not help very much if your scope only has 15K pixels. For this reason, optimizing the camera for the application has a much greater effect on image quality than does resolution or color saturation. With each application being different from the next, optimizing the camera for a given application will yield the best overall result. For an article by outside experts discussing this issue, click HERE. Another factor when deciding on a camera system for micro-endoscopy is the size and weight of the camera head connected to the scope. If a standard DIN eyepiece is connected to a DIN coupler and 3-CCD camera the difference in size and weight between the small scope and the camera becomes significant; making it difficult to maneuver and prone to breakage. BioVision has developed a mini-tower system that addresses these issues. For each unique application, our 4 oz integrated handpiece is digitally programmed to give the best overall picture for the application. This unique capability allows BioVision to not only develop the best scope for the application, but also to tailor the imaging system to the application. A truly customized solution for the application is the BioVision difference. Back |
