TIVITA® Suite basic software

TIVITA® Suite basic software associated with the TIVITA® Tissue is used to control the camera and record and display the hyperspectral data. It displays the RGB image extracted from the acquired data, the THI image, the oxygenation image, the NIR perfusion image and the TWI image.

RGB color image
The red-green-blue color image is extracted of the recorded data and a normalized color image.

Oxygenation (StO2)
The parameter describes the relative oxygen saturation of the blood in the microcircular system in superficial tissue layers. The penetration depth is about 1 mm.

Tissue Hemoglobin Index (THI)
The THI describes the existing hemoglobin distribution in the microcircular system of considered tissue area. This is an index and not an absolute value.

Near-infrared (NIR) Perfusion Index
The parameter describes the relative oxygen saturation of the blood in microcircular system in deeper tissue layers. The penetration depth can be 4 – 6 mm. This is an index and not an absolute value.

Tissue Water Index (TWI)
The TWI describes the existing water distribution in the considered tissue area. This is an index and not an absolute value.

In addition, it is possible to compare certain areas of the image by setting markers and to evaluate them numerically. For this, the arithmetic mean, the frequency distribution (histogram) and the averaged absorption spectrum are displayed from the set marker range.
