New video on the use of TIVITA® in visceral surgery

We’re delighted! Although 2019 is still a relatively young year, two groundbreaking publications have already been published dealing with our TIVITA® in surgical procedures. The two publications impressively demonstrate the potential of the technology in visceral surgery and the possible improvement of the clinical outcome of patients through objectification.
Many thanks to the working groups for their commitment and support of our TIVITA® – we look forward to future results!

New video on the use of TIVITA® in visceral surgery

In our new video, you can see the application of TIVITA® during a gastrectomy. The recordings were taken at the University Hospital Leipzig, where the surgical team around Prof. Dr. med. Ines Gockel, MBA and the Innovation Center Computer Assisted Surgery (ICCAS) conduct intensive research with TIVITA®. The video material was taken during the shooting of scientific works in preparation for the “International Gastric Cancer Congress 2019“. The congress will take place in PRAG from 8-11 May 2019.

Special volume “Optical Imaging Methods in Medicine” published 2018 in BME/BMT

Special volume “Optical Imaging Methods in Medicine” published 2018 in BME/BMT
After the electronic pre-publications, the paper edition for the special volume “Optical Imaging Methods in Medicine” of the scientific journal Biomedical Engineering of the DGBMT in VDE is now also available. The scientific contributions were based on last year’s symposium “Hyperspectral Imaging in Medicine” at the Institute for Biomedical Engineering at TU Dresden.
Due to the large number of contributions, our self-developed innovative HSI camera technology TIVITA® plays a very important role here.

Contributions of the special volume with TIVITA®:

  • Kulcke, A. et al.: A compact hyperspectral camera for measurement of perfusion parameters in medicine519
  • Holmer, A. et al.: Hyperspectral imaging in perfusion and wound diagnostics – methods and algorithms for the determination of tissue parameters 547
  • Markgraf, W. et al.: Algorithms for mapping kidney tissue oxygenation during normothermic machine perfusion using hyperspectral imaging557
  • Tetschke, F. et al.: Application of optical and spectroscopic technologies for the characterization of carious lesions in vitro595
  • Daeschlein, G. et al.: Hyperspectral imaging: innovative diagnostics to visualize hemodynamic effects of cold plasma in wound therapy603
  • Sicher, C. et al.: Hyperspectral imaging as a possible tool for visualization of changes in hemoglobin oxygenation in patients with deficient hemodynamics – proof of concept609

Furthermore, contributions are included which have been developed in cooperation with our long-standing cooperation partner Prof. Christoph Hornberger (University of Wismar):

  • Nahm, W; Hornberger, C; Morgenstern, U; Sobottka, SB: Optical imaging methods in medicine: how can we escape the plausibility trap? – Guest Editorial– 507
  • Hornberger, C; Wabnitz, H: Approaches for calibration and validation of near-infrared optical methods for oxygenation monitoring537

Once again, we would like to thank all involved parties, who made the publication as a special volume in BME/BMT possible, as well as all authors for the interesting publications and work with TIVITA®.

Photo Contest “My Research”

The dermatology working group in Rostock led by Prof. Emmert wins the photo competition “My Research” as part of the 2018 research camp.
Four doctoral students work with TIVITA® in the context of wound care in the Clinic and Polyclinic for Dermatology and Venerology. They jointly submitted the photo under the title “Alles im Bild – Hau(p)tsache ist viel Information” (“All in the picture – the skin issue / main issue is a lot of information”).
“In the field of dermatology, the individual tissue parameters and their pathological changes play an important role, e.g. in circulatory disorders. A reduction of the blood circulation of the skin and also water retention (edema) often lead to chronic wounds and other skin diseases. Clinically, so far, there were hardly any possibilities to objectively measure the oxygen saturation (StO2), blood circulation (NIR Perfusion Index) and water content (TWI) in affected areas of the skin with fixed values.
With the help of a spectral camera (TIVITA®), it is now possible to quantitatively record these parameters and thus also their changes in various diseases. The camera takes a photo, the tissue spectrum is recorded by absorption spectroscopy (from physics: different rainbow colours that make up the white light) and the computer converts the measured colour channels into the following parameters: blood circulation, oxygen saturation and water content. From a single image (which is captured in a few seconds) four images are obtained, each representing one of the four tissue parameters. The laterally displayed colour scale shows the colours, which represent the percentage of the measured value.
This information – as biomarkers, so to speak – gives us the opportunity to make statements about, for example, disease genesis, the effectiveness of individual therapeutic approaches and the healing process of chronic wounds. Together with 3 other PhD students, in clinical application (i) we are now investigating the normal values in different life decades, (ii) the values in patients with wounds caused by varicose veins, (iii) the values in patients with wounds caused by diabetes and arterial circulatory disturbance, and (iv) the change in the pathological values due to treatment with cold plasma.” © Stella Boleslawsky
We congratulate the winners and are very pleased about the good cooperation!

HSI workshop in Leipzig

On 14 November, a workshop on “Clinical results and accompanying scientific work in medical HSI technology in surgery” took place at the University Hospital Leipzig. The invitation of Prof. Gockel, Clinic and Polyclinic for Visceral, Transplantation, Thoracic and Vascular Surgery and Dr. Chalopin, Innovation Center Computer Assisted Surgery (ICCAS), was accepted by about 40 physicians, scientists and representatives of various companies.
The work presented and the resulting lively discussions repeatedly gave all participants an understanding of the technology and open questions in medicine.
We are pleased about the next workshop, which is planned for February 2019, and look forward with great excitement to the next results.

Release of the new TIVITA® Suite

After a long wait, many good ideas, a lot of work and some discussions, we are pleased to present the new software release of our TIVITA® Suite Tissue!

the new software release of our TIVITA® Suite Tissue!
The focus of the revision was on the redesign of the documentation tool (for direct comparison of images with each other, e.g.), improved navigation and patient selection. Furthermore, some new functions were implemented, bugs were fixed and optimizations were made.
A summary of the most important innovations of the TIVITA® Suite Tissue:

    • All images are now additionally saved as DICOM files
    • The documentation tool was made clearer
    • A comparison function was implemented in the documentation tool
    • The patient selection was equipped with a search function
    • The localization selection has been simplified with a clickable graphic
    • An ambient light detection with warning during recording could be implemented An ambient light detection with warning during recording could be implemented
    • The calculation speed was improved
    • The pdf-reports have been optimized
    • The load graphic was optically upgraded and “diaspectivated”.

The following graphic shows the comparison function in the documentation tool.

With the new software, any two measurements of a documentation can be selected and compared in the course of time. This way, differences before and after a treatment can directly be detected.

The new software version 1.5.1 is in the final stages of the approval process and will soon be available to all new customers. Do you already have a TIVITA® Tissue System? Your software can also be updated. Contact your TIVITA® partner for further information!
We hope that the new version will make the use of our hyperspectral camera TIVITA® Tissue even easier and more comfortable.
