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.

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.

Funding notification of “KMU innovativ: Medizintechnik”

Just yesterday, we received the good news that our submitted project LYSiS (which stands for Laparoscopic Hyperspectral System) has been approved.
This project involves the development of a small hyperspectral camera that can be used for laparoscopic procedures. We are working on this project together with ICCAS Leipzig and the University Hospital (department of Visceral Surgery) Leipzig.
Minimally invasive surgery plays a decisive role in medicine and imaging procedures are becoming increasingly important in supporting physicians. For this reason, we can be curious about future developments.
We are looking forward to this cooperation and to early results!

Bacteria shining in any shade of colour

The collaborative project Bacteria-CAM has been running for a while now and keeps both, our employees and our partners, busy. As often, many tasks have to be carried out until the first concrete results start coming.
For example, many components have already been developed for the prototype, a great deal of software has been written and many optimization steps have already been performed for the function prototype. The work around the integration into a fluorescence microscope has also caused quite a bit of time and effort and finally, the outdated lighting unit turned out to be a barrier.

More pleasing are now the first results of germ cultures in Petri dishes!

Below, the hyperspectral camera system for fluorescence spectroscopy for the examinations is depicted:

The following pictures show some screenshots of the development environment for the pre-evaluation.
The first analysis shows some clear spectral signatures of the bacterial cultures.

After a Principal Component Analysis (PCA), they lead to a direct colour image presentation with the Chemical Colour Imaging (CCI) technology.
A second culture with other bacterial species is shown in the following:

In addition to the PCA transformation, the cluster analysis also provides pleasing results. It is easy recognizable in the next screenshot, that a segmentation of the areas is feasible and that this one also corresponds to the different spectral signatures.

We are looking forward to the next few weeks, in which the bacteria will be systematically examined and the basis for germ assessment in wounds will be established.

Diaspective Vision wins funds from the European Union within the health economy idea contest

By winning the ideas contest in the summer of 2017, Diaspective Vision secured further public funding from the European Union. The notification for the grant from the European Regional Development Fund (ERDF) reached us at the end of the year and continues to motivate us to work on interesting topics.

The project “Standard diagnostics upon the admission of new guests with vascular diseases in the spa clinics and spa hotels in Mecklenburg-Western Pomerania for the creation of an individual, optimal supporting program for the specific improvement of health”, short KUR-ART-MV, should improve the care for patients with wounds after their discharge from hospital and prevent the development of wounds in vulnerable patients. One additional goal is to increase the attractiveness of Mecklenburg-Western Pomerania as health country.

We are looking forward to the exciting tasks and will keep you informed on our homepage about the development results.
