Phonocephalography extra-cephalic.

Area of Science:

• Medical Diagnostics
• Bioacoustics
• Non-invasive Imaging

Background:

• The evolution of medical diagnostics includes advancements in non-invasive techniques.
• Auscultation, since Laennec's stethoscope, has become a key diagnostic procedure in cardiology.
• There is a continuous drive towards developing simpler, non-invasive diagnostic methods.

Purpose of the Study:

• To introduce phonocephalography as a non-invasive pre-angiographic diagnostic technique.
• To explore the amplification and recording of sounds from the head's surface and cavities.
• To demonstrate the feasibility of phonocephalography and its application to the vertebral column (phonomyelography).

Main Methods:

• Amplification and recording of sounds from the head's surface and cavities.
• Utilizing nasopharyngeal phonocephalography for sound recording.
• Applying the phonocephalography concept to the vertebral column for phonomyelography.

Main Results:

• Nasopharyngeal phonocephalography demonstrated successful recording of normal tracings.
• The study discussed the influence of extra-cephalic sounds and other factors on the recorded tracings.
• Phonomyelography tracings from the vertebral column were successfully recorded and demonstrated.

Conclusions:

• Phonocephalography is a viable non-invasive technique for pre-angiographic assessment.
• The study successfully demonstrated the application of sound recording techniques to the head and vertebral column.
• This research contributes to the development of novel non-invasive diagnostic tools in medicine.
