Digital Video Stroboscopy System, Model
9295
A Complete Endoscopy/Stroboscopy
System
The
Digital Strobe is an advanced laryngeal imaging system that digitally records
stroboscopic, and other endoscopic, exams to a fully-integrated video capture
and playback workstation. Designed for otolaryngologists, phoniatricians, speech
pathologists, and voice scientists, the Digital Strobe has become the system of
choice at leading hospitals and voice clinics internationally since its
introduction in the late 1990s. The latest iteration boasts an unparalleled
array of features to provide the best imaging system available for comprehensive
assessment of the vocal folds’ structure and vibratory characteristics. It can
also be used to record other endoscopic procedures (e.g., transnasal
esophagoscopy) with superior image quality and enables clinicians to take
advantage of the system’s many built-in features designed to enhance clinical
efficiency. No other stroboscopy system can match the Digital Strobe in
performance robustness.
The Digital
Strobe complements the entry-level stroboscopy systems from KayPENTAX to provide a
complete family of endoscopy/stroboscopy systems appropriate for any budget
and performance requirement.

Superior Stroboscopy Light Source
The key
component in any “true” stroboscopy system is the light source. KayPENTAX's Stroboscope, Model 9100B uses 5-microsecond flashes to freeze the quickly
vibrating vocal folds, thereby providing razor-sharp image clarity
throughout the glottal cycle over a wide range of fundamental frequencies
and vocal amplitudes. Shuttered-camera approaches which attempt to mimic
stroboscopy are unable to match this image quality which is particularly
evident when recordings are paused for image analysis or printing a still.
KayPENTAX's light
source contains all of the key features for maximum quality and versatility:
excellent illumination of laryngeal structures with both xenon and halogen
(constant) light sources; slow, fast, and locked modes for viewing the vocal
folds in motion or in a “fixed” position within the vibratory cycle; foot
switch control of important functions; LED display of amplitude and
fundamental frequency; audio preamplifier; accurate pitch extraction over an
extensive range; throat microphone or electroglottograph (EGG) input; fast
lock-on time; and field-replaceable bulbs.
Many
stroboscopy light sources vary in brightness during the glottal cycle
resulting in a “blinking” image quality. This effect may be accentuated with
changes in amplitude and fundamental frequency. KayPENTAX’s light source includes
a special circuit that eliminates blinking video and provides uniform
brightness throughout the patient’s pitch and amplitude range.
Powerful Image Capturing System
The
Digital Strobe includes all of the capabilities to capture streaming video
without artifacts. Audio (patient audio or examiner comments) and video are
captured together. To ensure precise color accuracy and fast setup, the
computer system downloads optimized camera settings for each endoscope. The
image quality is excellent with progressive scan display (no flicker). Once
captured, images (both stills and MPG or AVI video clips) can be played or
viewed in other computers, sent electronically to colleagues, or placed in a
PowerPoint presentation.
In addition
to its use in recording stroboscopy exams, the Digital Strobe can also
record other endoscopic procedures or surgeries. Its built-in database and
exam management system allow these procedures to be easily accessed for
review at any time.
Professional
Quality Video
Medical
records require high-quality video images without artifacts. KayPENTAX’s Digital
Strobe provides accurate, artifact-free broadcast quality images with
superior resolution and clarity. Adjustable parameters facilitate capture of
all types of video images with excellent quality including rigid endoscopes,
flexible (fiberoptic) endoscopes, and videoscopes (i.e., chip-tip cameras).
Control of
Camera
A key
benefit of KayPENTAX’s system is software that includes special code for
automatically loading optimal camera settings (defined by the user) with
each endoscope and light source used. With this feature, the examiner
obtains consistent color, appropriate camera sensitivity, and faster
examinations because there is no need for ongoing camera adjustments. The
result is greater clinical efficiency and consistent image quality.
One Person
Operation
The Digital
Strobe is designed to enable a clinician to perform exams unaided by staff.
This is made possible by a foot switch/pedal which controls key light source
controls. It also controls video record/pause so that only desired segments
of an examination are digitally recorded.
Instant Review
of Exams
Playback of
an exam on the Digital Strobe is immediate. The benefit in time saved is
actually minutes per exam when compared with systems that store procedures
on a tape medium. The user can quickly move to the beginning, or to any
frame, of the exam and play the recording.
Playback of
Two Exams Side by Side
Two patient
exams can be loaded concurrently and compared side by side. This feature
facilitates accurate assessment and in-depth comparison of patients before
and after therapy, or surgery.
In just
seconds, two exams can be loaded to facilitate comparison.
The Digital Strobe is an unparalleled laryngeal imaging platform in terms of
performance and many extra features that enhance clinical efficiency.
Patient
Database and Exam Management System
The Digital
Strobe is much more than a system for capturing and playing streaming video.
With its built-in patient and examination database, clinicians are relieved
of the responsibility of cataloguing previously recorded exams; the system
loads them instantly after accessing the patient’s name with exam listing(s).
Associated with each patient is not only the location of stored exams for
convenient retrieval, but also a database containing important patient
history, and key exam findings listed under user-definable fields and
editable entries.
A montage,
automatically generated, presents a quick snapshot of
the patient's vocal fold structure and vibratory pattern.
Report
Generator
After the
clinician has filled in appropriate database fields, entered comments, and
selected key stills from the exam, the Digital Strobe automatically
generates a report containing this data as a Microsoft Word document. The
user can select which database segments to include in the report, making it
possible to generate a concise single-page summary or a more comprehensive
multi-page document. The report can be printed for patient records, a
referring physician, or insurance filing.
Digital strobe
software generates a convenient report containing selected stills and a
summary of key exam findings.
Optional Video
Formats Supported
Exams
recorded on the Digital Strobe are normally viewed on the system itself.
However, clinicians can use the utilities provided to convert exam segments
to MPG and AVI video formats. These video “clips” can be inserted into
presentation graphics programs (e.g., PowerPoint) or sent electronically to
a colleague.
Valuable Extras Provided with the
Digital Strobe
Video Viewer
The Video
Viewer is a software program that allows Digital Strobe exams to be reviewed
on other computers in their native format (without converting to a
multimedia video format). For example, the Video Viewer is used to play the
collection of exams provided in the laryngeal pathology database described
below. With the Video Viewer, these (or other) exams can be played in a
computer (e.g., in a classroom) remote from the Digital Strobe system.
Database of
Stroboscopic Recordings of Laryngeal Pathologies (DSRLP)
Assembled
at a leading voice clinic, DSRLP is a collection of some 80 stroboscopic
recordings covering an extensive range of laryngeal pathologies. Multiple
examples of each disorder are provided. Each case includes a running speech
sample from the patient, and a stroboscopic exam using both flexible and
rigid endoscopes. This collection is an excellent resource for students and
residents.
The laryngeal
pathology database contains
exam segments from some 80 laryngeal
pathologies. Running speech and stroboscopic
assessment are provided on each patient.
Five-Hour
Video on the Usage of Stroboscopy for Assessing Dysphonia
Authored by
Drs. Guy Cornut and Marc Bouchayer, this impressive educational tutorial,
consisting of three DVDs (and an e-book on CD), methodically covers all
aspects of stroboscopy and its usage in the voice clinic. In addition to its
excellent overview of stroboscopy, it presents some 125 cases covering an
expansive range of disorders. It is touted by leading laryngologists and
speech pathologists as the most comprehensive educational video available on
the role of the stroboscopic procedure in assessing laryngeal disorders.
Digital Strobe
Voice Analysis Program (DSVAP)
This
software program is a subset of KayPENTAX’s acclaimed Multi-Dimensional Voice
Program (MDVP) used by many speech pathologists for the acoustic assessment
of voice. DSVAP is designed for the otolaryngologist who wishes to obtain a
few key acoustic parameters and a high-fidelity voice recording on their
patients for pre- and post-treatment comparisons.
Acoustic
assessment of the patient's phonation is provided with the Digital Strobe
Voice Analysis Program.
Video Server Option
Busy
clinics with multiple Digital Strobe systems and exam rooms can take
advantage of KayPENTAX’s Video Server. The Video Server acts as a central storage
location (with ~1 Terabyte RAID5, hot-swappable hard drives) for
stroboscopic (and other endoscopic) procedures. It provides clinicians with
instant access to the most current 1,000 examination recordings, assuming ~3
minutes/exam, viewable from any Digital Strobe (or viewing station)
connected to the Video Server. Any exam can be played from any procedure
room.
In addition
to this core capability, other key aspects of convenient operation, system
maintenance, and reliability have been designed into the Video Server. For
example, incremental backups of exams to a tape drive (supplied with the
package) are performed automatically on a daily basis. Additionally,
centralized printing allows reports and excellent quality images to be
printed remote from procedure rooms to free the stroboscopy system for the
next patient.
Complementary Laryngeal Imaging
Products
As a leader
in the field of voice, KayPENTAX provides the latest instrumentation technologies
to clinicians and researchers. Videokymography (VKG) and High-Speed Video,
both provided by KayPENTAX, are powerful imaging techniques that complement
stroboscopy. These methods permit observation of vocal fold vibratory
characteristics regardless of periodicity (e.g., the onset of phonation). VKG and High-Speed Video are being used by the research community and in
selected clinics. Their usage will likely grow as quantitative methods for
analyzing these images emerge.
A Complete Voice Lab
To
complement stroboscopic and laryngeal imaging products, KayPENTAX offers a full
line of acoustic, aerodynamic, and electroglottographic instruments for the
voice lab that are used for multi-parametric patient assessment and visual
feedback in rehabilitation. As with KayPENTAX’s stroboscopy system, these
instruments are cited frequently in peer-reviewed articles and are the
leaders in their respective product categories.
Kay'PENTAX's Digital Strobe and other voice lab instruments are frequently cited in
books and professional journals as the tools of choice in the leading voice
clinics worldwide.
