Synchronized audio, video and fluoroscopy documentation during speech, swallowing and cleft palate examinations

Capturing images through low-dose fluoroscopy acquisitions

Every three minutes, somewhere in the world a child is born with cleft palate.1 This is just one of many groups of patients who may need to undergo examinations to diagnose speech and swallowing disorders - the latter also known as dysphagia. Other groups may be stroke and cancer patients.2, 3 There are several different examination methods to diagnose speech and swallowing disorders, such as laryngoscopy, esophagoscopy, nasometry, nasopharyngoscopy, cineradiography and X-ray guided cephalometry.

PharyDoc is a complement or alternative to other examination methods, to decide the best course of treatment and to follow up on surgery results. In newborns and children, it is essential to keep radiation exposure as low as possible. By capturing low-dose fluoroscopy acquisitions, PharyDoc is a unique examination method to help achieve optimized radiation exposure.

Delivering full control to speech pathologists and maxillofacial surgeons

With the help of PharyDoc, you can record and save synchronized fluoroscopy, patient video and audio from a Video Fluoroscopic Swallowing Examination (VFSE) or Therapeutic Videoradiographic Swallowing Study (TVSS). The system simultaneously captures an X-ray input, video camera input and two microphone inputs (patient and operator audio) - recording starts automatically with the fluoroscopy exposure. The nature and relation between sound and moving images can be studied during the procedure and afterwards.

Create, share and save selected sequences for review

All elements captured during the examination remain synchronized during playback, which can be continuous or frame by frame. With ParyDoc, video snippets with selected sequences of interest can be created and shared. The synchronized viewing of all captured sources allows for detailed examination reviews. For example, you can use PharyDoc to extract Oral Transit Time (OTT) and Pharyngeal Transit Time (PTT), as well as for frame-by-frame slowmotion analysis and retrospective quantitative analysis.4, 5, 6

Examinations captured at the workstation are easily accessed from other hospital computers with separately installed software clients, such as an auditorium. It is also possible to connect two or more labs and save all examinations in a common data storage - locally or on a separate storage device.

Synchronized documentation

With PharyDoc, you can save fluoroscopy examinations with synchronized video and audio in the system’s central storage - something that many PACS systems are incapable of.
Consequently, sound playback when using a PACS viewer cannot be guaranteed.

PharyDoc is a vendor-neutral complement to the image storage application in the X-ray system. The examination is linked to the unique patient identification number and all images are stored automatically in a central storage and then manually selected within the software to be sent to PACS.

The examination could be transmitted digitally to an electronic picture archiving and communication system (PACS or PharyDoc) to provide rapid retrieval and analyses of the entire swallowing sequence. The availability is excellent and easy to handle and any pathophysiology could be analysed in detail related to the flow of different given textures.

Supporting Operation Smile

Every three minutes, a child is born with cleft palate. Lots of children suffer from social stigma, malnourishment and speech problems and lack the financial means to get proper treatment for their condition. We are proud to support Operation Smile, a global network of medical professionals and volunteers who perform surgery for free to change the lives of these children.
