International conference in Mayo Clinic (Phoenix, Arizona)

29th of March 2023
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".

ALIS used in research on the post-COVID-19 syndrome

24th of July 2022
Congratulations to the team led by Professor Wioletta Pietruszewska and Professor Ewa Niebudek-Bogusz from the Medical University of Lodz for publications on dysphonia during post-COVID-19 syndrome.
We are proud that our high-speed camera set – ALIS – has been successfully used for diagnostics during the research.

Below is a link to the publication based on the results of this scientific work:
Isolated Severe Dysphonia as a Presentation of Post-COVID-19 Syndrome

Presentation at UEP Voice Committee meeting

20th of June 2022
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 publications about ALIS with high-speed camera

24th of November 2021

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 studyNature,

Advanced Larynx Imager System (ALIS) By DiagNovaePhonoscope.

New! Live strobo preview during High-Speed recording!

21th of June 2021

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.

New! Laryngeal imaging with real-time kymographic preview!

11th of June 2021

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.

DiagNova Technologies at MEDICA 2019 fair

18th of December 2019

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

DiagNova Technologies na targach MEDICA 2019

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 ( 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.

DiagNova Technologies at Pacific Voice Conference

26th of October 2019

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