DiVAS video archiving and analysis software A high-performance software is essential for the fast and efficient use of findings for diagnostics and therapy. DiVAS provides professional tools and convinces last but not least by its re-designed user friendly, intuitive user interface. The program allows you to comfortably record, archive and assess video sequences, still images, and measuring data. A range of export features integrate the data into findings documentation, publications and training sessions and material.the data can be synchronized with the data of the practice or clinic management software or vice versa. DiVAS has a modular design and can be added on at any time thus always being up-to-date. digital IEEE 1394/FireWire interface record videos either in MPEG-2 format or in DV format support of USB cameras record video sequences or single images view the video image by image fullscreen mode diagnosis input per session navigate through video or view single video frames one by one in the thumbnail view with selectable time resolution allocate an image from the video to the session to mark the session in the list video cut function compare 2 video sessions on 1 screen and view therapy progress various export functions for video and image data e. g. into MS Word or MS PowerPoint files, use in treatment documentation, presentations or training easy draw up of documents or patient reports using print templates print function data back-up on DVD, CD, network or external hard disk with automatic reminder graphical display of disk space data exchange with practice or clinic management software through GDT interface comfortable management of patients and examination data enter patient data manually or through chipdrive search and assorting functions in list of patients management of several examiners sterile recording control by foot switch or camera head s control buttons PAL and NTSC supported intuitive multilanguage user interface extensible through modular architecture DiVAS modules: basic/patient management video documentation video documentation with video strobokymography photo documentation electroglottography (EGG) phonetogram voice analysis voice strain test 63
basic/patient management This module is the basis of the work with DiVAS and required for the use of all software modules. 350 020 000 DiVAS basic/patient management module patient management enter patient data manually or through chipdrive search and assorting functions in list of patients examiner management enter, save and change examiner data in list of physicians, sorting functions in the list managing sessions sessions from all modules are automatically allocated to the patient and managed in the patient's file generate sessions upon entering patient data or use the "Quick Start" function to open a session without prior input of patient data and complete the patient file later, or allocate the session data to an existing patient, or scrap them data backup backup either all data or only new and changed data, automatic backup reminder cleaning the hard disk delete videos, images and measuring reports after the session at the same time keeping session information retrieve session data by mouse click in list of sessions data import and data export export session data and import comparative data, easy and fast export of images and diagrams in different MS Word templates of individual layouts such as doctor's letters, operation reports, etc. managing MS Word documents automatic saving of MS Word documents in list of sessions, simple managing and working in the document from list of sessions 64
video documentation 350 020 010 DiVAS video documentation module record videos either in MPEG-2 format or in DV format video replay image by image or as video sequence including audio thumbnail view view single video frames one by one in the thumbnail view cut videos without losses print function print single images, remove image background when using small lenses to save toner export functions export videos and single images for example into MS Word files, graphic or video files, or to the clipboard mark session with image allocate an image from the video to the session to mark it in the list "Endoscopy" perform endoscopy viewing the live image in fullscreen mode while recording a video and/or images at the same time documentation mark single images in the thumbnails and integrate them in one of the templates for printing 65
videostrobokymography Strobokymography is an easy and low-cost way to calculate kymograms from individual stroboscopic videos. The assessment of stroboscopic images has been possible image-by-image only so far. Due to the simultaneous display of the oscillation phases of a vocal cords section, the assessment has clearly improved and become more exact. Differences in amplitude and phase, deviations of symmetry and periodicity of the vocal cords oscillations are easier detectable and quantifiable. Videostrobokymography is an additional method of voice diagnostics available to a broad range of users. 350 020 015 DiVAS strobokymography module, extension of video documentation module 350 020 010 integration into daily practice routine without extra time effort strobokymograms generated after recording stroboscopic images increased diagnostic value of stroboscopic records simultaneous depiction of oscillation phases of vocal cords extract no additional hardware required inexpensive compared to known procedures definable scan line configurable number of images to be scanned easy saving, export and analysis of strobokymograms 66
