From December 1–5, 2025, our ALIS – Advanced Larynx Imaging System was tested at the University Hospital in Plzeň. The equipment was loaned for clinical evaluation by the team led by Dr. Monika Vohlídková.

The testing took place as part of an emerging collaboration with MGVIVA, a company interested in becoming our official distributor in the Czech market.

To make the future users' experience as smooth as possible, we prepared a Czech-language version of the DiagnoScope Specialist software, tailored for local users.

Over the course of several busy days, the system was used in patient examinations as well as in educational and demonstration scenarios. One memorable moment we captured was when a representative of the distributor volunteered to be examined himself – a gesture that perfectly illustrated their full engagement and interest in the technology.

We are pleased with the positive reception of the ALIS system and proud to share that our collaboration with MGVIVA is now entering the next stage – preparations for the first purchase.

DiagNova continues to expand its footprint in Europe, and the Czech Republic may soon join the list of countries where our technology supports cutting-edge voice and glottic diagnostics.

On October 2–4, 2025, we had the honor of participating in the 21st International Conference of the Oncology Section of the Polish Society of Otolaryngologists – Head and Neck Surgeons titled „Head and Neck Oncology 2025. Advances in Otolaryngology”, held in Łódź.

This was one of the most important scientific events in the field of head and neck cancer, bringing together experts from a wide range of disciplines – from otolaryngology to maxillofacial surgery, clinical oncology, radiotherapy, and other medical specialties.

We sincerely thank Prof. Ewa Niebudek-Bogusz, MD, PhD and Prof. Wioletta Pietruszewska, MD, PhD for the invitation to this exceptional event.

We are proud that DiagNova’s technologies are supporting the advancement of modern diagnostics in oncological laryngology – both in scientific research and daily clinical practice.

On 23rd and 24th of June, we had the pleasure of visiting Zurich at the invitation of Dr. med. Daniel Runggaldier and Prof. Jörg Bohlender. The meeting was an opportunity to present our ALIS – Advanced Larynx Imaging System and DiagnoScope Specjalista software in action.

It was a valuable visit for us – not only a chance to demonstrate the system live, but also a space for exchanging experiences and discussing the current challenges of modern laryngeal diagnostics.

We sincerely thank our hosts for the warm welcome, inspiring conversations, and the great atmosphere – including, of course, the famous Swiss hot chocolate.

We are proud to announce that our ALIS (Advanced Larynx Imaging System) set – an advanced system with high-speed video laryngoscopy camera – used by the team of Professor Wioletta Pietruszewska and Professor Ewa Niebudek-Bogusz from the Medical University of Lodz, constantly provides data that are used in subsequent peer-reviewed scientific publications in prestigious medical and technology journals.

Our company took part in the prestigious international congress of ENT specialists - 15th Congress of the European Laryngological Society, which took place on May 8-10, 2025 in Warsaw.

At the exhibition accompanying the scientific sessions, we presented our products and solutions dedicated to otolaryngology specialists. The set with a high-speed camera – ALIS (Advanced Larynx Imaging System) aroused particular interest and attracted the attention of congress participants from all over the world. The participants could also learn about the system from the scientific works carried out by the team from the Medical University of Lodz with the help of ALIS, which were presented in the lecture halls.

Participating in the congress was an excellent opportunity for us to present our offer to a wide range of medical specialists and to establish new, valuable industry contacts. We are pleased that our innovative solutions have met with such great interest and positive reception.

At the same time, we announce further development of our offer and participation in subsequent industry events, promoting innovations supporting the work of otolaryngologists around the world.

Congratulations to Magdalena Kowalczyk (MD, PhD Student at Medical University of Lodz) for her speech at the 7th Congress of the Confederation of European ORL-HNS 2024 in Dublin (15-19th of June 2024).

The topic of the presentation "High-speed videoendoscopy enhances the objective assessment of glottic organic lesions" is very close to us and we are pleased that the material for the presentation was created using our set with a high-speed camera - ALIS.

We are happy to announce that we have just arrived in Phoenix and we are getting ready for the 15th International Conference on Advances in Quantitative Laryngology, Voice and Speech Research 2023 in Mayo Clinic, where Michael Tyc, Ph.D. will give a presentation on Saturday entitled "A Novel Approach to High-Speed Transoral Fiberoptic Phonoscopy of the Glottis".

We would like to thank Professor John Rubin for inviting us to the Voice Comittee meeting of the Union of the European Phoniatricians which took place on June 20, 2022.
It was a great opportunity to present our high speed camera set – ALIS . We sincerely hope that our presentation has been found interesting.

We invite you to read the presentation in which we describe the operation of the equipment and the methods of data analysis.

More and more research centers use our high-speed system ALIS! We invite you to read two very interesting publications on this topic:

Comparative analysis of high-speed videolaryngoscopy images and sound data simultaneously acquired from rigid and flexible laryngoscope: a pilot study – Nature,

Advanced Larynx Imager System (ALIS) By DiagNova – ePhonoscope.

To meet the expectations of specialists, we have added a new feature, unique on a global scale – the image on the screen during the preview in the high-speed slow motion sequence recording mode can present slow motion of the vocal folds, similarly to the stroboscopic examination. At the same time, a kymographic cross-section can be displayed on the screen, which – in order to facilitate the observation of vibrations of the vocal folds – is also synchronized with their movement, showing the glottal cycle always starting from the closing phase. We obtained both effects thanks to the innovative technique of analyzing the kymographic cross-section generated continuously, and determining the fundamental frequency of the voice and the vibration phase of the folds from it. This is an image-controlled strobe method which does not require an additional microphone. Contrary to the classic stroboscopy, it works instantaneously (it does not require the synchronization, typical for classic stroboscopes); it also works for vocal folds movement of lowered regularity or reduced amplitude.
Stroboscopic video preview in combination with real-time kymography allows for instant assessment of the function of the vocal folds with various types of phonation (e.g., low and high pitch) already during the examination, enabling the optimal selection of the moment of slow motion recording sequences in order to obtain comprehensive information about the condition of the voice organ. A video recorded with use of both of the newest functions is presented below.

We have added the ability to preview kymographic cross-sections while recording High-Speed Video! In the center of the screen, you can see the current view of the camera image, in parallel a kymographic section (from the marked line) is displayed in real time in the upper right corner.

Thank you for visiting us at MEDICA 2019 fair in Düsseldorf. This year we have presented our products at the Polish national exposition.

The fair was a very fruitful time for us. The breakthrough event during the fair was the possibility to perform preliminary tests of using our camera with a fiberscope in the high-speed mode and in the violet light mode. Until now, due to the extremely high illumination intensity required, high-speed cameras were only used with rigid endoscopes. Thanks to the courtesy and with the participation of Fiegert Endotech (www.fiegert-endotech.com) company, we conducted tests of their fiberscope, whose special properties allowed recording colour slow-motion sequences at 2400 frames per second with our high-speed camera. The results of the tests performed are very promising, and the obtained images seem to be bright enough to be applied in clinical diagnostics.

We thank all the visitors of our booth at the international XXVII Pacific Voice Conference (EU-Poland Edition), which took place on October 24-26, 2019 in Cracow.

Our advanced larynx imaging system received great interest from the circle of international specialist in laryngology and phoniatry, as well as from people using their voice professionally every day. During the conference, a few dozen people (mainly the students of the Voice Department of the Academy of Music in Cracow) were examined with the help of our system. The camera was used by many specialists and, despite the fact that most of them were using it for the first time, nobody had problems with operating it; however, the unique proficiency of one of the conference attendees, Dr. Agnieszka Garstecka, who is using such a system for almost a year, could be easily distinguished.

We also thank for listening to the presentations making use of the neoglottis function records taken with the help of our high-speed camera ALI Cam-HS1:

• “Love, hate, and a kitty on the fence” – Zimmer-Nowicka J., Just M., Tyc M., Racino A. & Izdebski K.
• “Neuro-physiology of emotional alaryngeal voice based on HSDP observations” – Just M., Zimmer-Nowicka J., Tyc M., Racino A. & Izdebski K.

• “New concept of using a high-speed camera for application to various voices” – Just M., Tyc M. & Racino A.
