With the TIVITA® Wound System, we set new standards in wound diagnostics!

Until recently, in the treatment of wounds there were no adequate measuring devices, which can support diagnosticians and clinicians in the assessment of wounds and the documentation of healing progresses. Thus, there are often unnecessary long wound healing times and avoidable subsequent costs – especially in the area of chronic wounds.

Spectroscopic measurement methods in the visible and near infrared range (VIS/NIR) already are standard methods in patient monitoring.
Furthermore, multispectral photometry is already applied in skin cancer detection. Because of our innovative HSI-camera technology, a multitude of applications areas can be opened up in medical field.

A comprehensive overview is provided by Medical Hyperspectral Imaging: A Review by Goulan Lu and Baowei Fei and Review of near-infrared methods for wound assessment by Michael Sowa et al.

We at Diaspective Vision have extensive experience and knowledge in the above-mentioned subjects and set new standards in these areas.

Recently, we developed a new camera system: the TIVITA® Wound.



For the first time, it will enable diagnosticians to qualitatively and quantitatively assess and describe wounds in a non-invasive way within seconds.

This, in turn, hinders physical activity, which ultimately leads to negative effects in the oxygenation of the wound and impedes wound healing. Thus, a controlled documentation of the wound healing process is paramount and an important tool in the decision on the right therapy.

Regardless of their different genesis, chronic wounds portray a relatively universal pathophysiological image of impaired wound healing.
Factors such as lasting tissue hypoxia, necrosis, infection, under nourishment or an imbalance in wound moisture levels have an impact on the healing process of wounds. For the assessment of tissue hypoxias, technologies such as transcutaneous oxygen measurements (tcpO2) or the tissue oximetry (NIRS) are used.
Both procedures can only be applied next to the wound and do not provide information in image format.
In contrast, the HSI-based tissue oximetry method provided by the HyperWound-CAM can acquire data directly from the wound area and gives even further information such as water concentration and additional chemical changes in the wound.

The correct and timely diagnosis of chronic wounds and their documentation is of significant importance in terms of the following issues:

  • Assessment of the healing progress via individual case analyses
  • Decision on which wounds can be treated under which circumstances in outpatient care
  • Reduction of (inpatient) treatment times
  • Approaches to the improvement of quality assurance

The following examples show sample records of wounds. They were shot with our hyperspectral camera, the TIVITA™ Tissue.
The processing of the spectrometric data across the wound area results in a first approach in the determination of the superficial perfusion, that is oxygenation of the hemoglobin (StO2), the volume of blood (tissue hemoglobin index – THI), the perfusion quality in the deeper layers of the wound (NIR) and their representation in a pseudo color image.

Offene Wunde am Fuß nach Amputation bei einem diabetischen Fußsyndrom mit schlecht versorgten Bereichen innerhalb der Wunde. Die Oxigenierung erscheint gerade im Bereich der Zehen unzureichend.

Open foot wound after amputation in diabetic foot syndrome with poorly-attended areas within the wound. Oxygenation seems to be inadequate, especially in the area of ​​the toes.

With our TIVITA® Wound system, we provide a way to document the recorded data and present it in a timely manner. It enables the classification of different tissue types. Below a look at the documentation tool within the software is provided.

“The rapid progress in computing, connectivity, and photonics along with the economic scaling of those technological centerpieces, in confluence with the urgent drive toward cost containment within our health care systems, suggests we are poised for a technological revolution that will enable patient empowered wound monitoring outside of the traditional hospital setting. Taken together, NIR-based technologies can play a central role in this revolution, providing tools to assess wounds along the entire healing trajectory from hemostasis and inflammation to wound remodeling and scar formation.”

„Around 2.7 million people in Germany suffer from complex wounds. With 890,000 of these patients, these wounds take a chronic course. Behind these numbers, individual fates with sometimes long lasting tales of woe are hidden. This is because chronic wound patients usually are aged, multimorbid, disproportionately in need of care and more often treated as inpatients compared to patients without wounds […]“
