HSI for medical purposes has not yet reached mass production and a broad market.
Further miniaturization down to the millimeter scale is needed if the highly interesting opportunity of integrating with endoscopes and other miniature devices is to be pursued. This prototype was first presented at the SPIE Photonics West conference in 2012. Innovative designs for CMOS arrays using elements such as Fabry-Pérot staircase concepts have helped create the first miniaturized prototype, sized at a little over 1 cm 3. On the other hand, extended research is currently being conducted on microelectronic parts. This restraint makes the technology unsuitable for time-critical applications and requires further research. Making HSI cheaper, user friendly, and more compact is the major goal in HSI research.įurthermore, existing HSI cameras are only able to scan one line at the time, mainly due to their design and mechanically moving components, limiting frame rates. The devices currently available are large, expensive, and difficult to handle. Today, most HSI use is confined to laboratories. Their low frame rates are another disadvantage negatively affecting the possibility of further medical application. Current devices are highly expensive, large, and difficult to use. Probably the greatest weakness of HSI is the technologies’ immaturity. A vast number of potential applications have been shown for this novel imaging technology-for instance, the accuracy rate of tongue tumor detection with computer-aided HSI is 96.5%. Furthermore, automated detection of pathologies is possible. It can aid in the discrimination between healthy and malignant tissue. HSI provides additional diagnostic information that can be exploited in various different ways. In order for the analyzing algorithms to extract the color information needed, the distinct reference spectra have to be implemented precisely. The tissue imaged provides a complex multicolor data set. Furthermore, the right calibration is crucial. The cameras can be customized to meet the wavelength or the application-specific performance needed. Schematic Setup of hyperspectral imaging camera, <.
