The camera technology to record and display chemical information in images.

The TIVITA™ Tissue System consists of a hyperspectral camera and its respective analyzing software. It enables you to extract chemical characteristics of test objects, tissue samples etc. via hyperspectral images. The camera operates in the range of 500 – 1000 nm, meaning in the visible and near infrared spectral range, thus it is especially suited for examining divers biologic materials.

Functionality of the TIVITA™ Tissue

The following illustration depicts the functionality of the TIVITA™ Tissue schematically.
Hand-Innenseite_Comp

A spectrometer and scanning unit, integrated into the camera, acquires the hyperspectral data of the object, tissue or sample. The data is transferred to a PC- or laptop-bound analyzing software where it is processed visually for the user (creation of pseudo-color images).
The images created this way, can be scaled through various settings in order to focus on either the optimal image resolution or the optimal scanning speed.
Usually, a data cube with the dimension 640 x 480 x 100 (px x px x wavelength) is recorded within 4 to 5 seconds. An overview of the different image sizes in relation to various parameters is depicted in the following schematic.

In the image below shows the course of an occlusion of the right arm. It displays the color images, the hyperspectral images of the oxygenation (in two pseudo-color variations) and the tissue hemoglobin index (THI) – in normal condition, during the occlusion of the arm and during the reperfusion, after the occlusion was lifted.

A change in oxygenation can be seen in the following image as well. The Perfusion of a single finger was suspended. While the color photograph shows almost no different oxygenation levels in the Hand, the hyperspectral image recorded with the TIVITA™ Tissue shows very significant differences.

As part of an internal validation study for the TIVITA™ Tissue an occlusion test was performed and the results are shown in the following video.

The TIVITA™ Tissue can be either delivered with just the spectroscopic camera (with or without the lighting unit) or as a whole system with a cart and an adjustable swivel arm.
