  2. Harmonic scalpel - Wikipedia

    en.wikipedia.org/wiki/Harmonic_scalpel

    A harmonic scalpel cuts via vibration. The scalpel surface itself cuts through tissue by vibrating in the range of 55,500 Hz. The high frequency vibration of tissue molecules generates stress and friction in tissue, which generates heat and causes protein denaturation.

  3. Violet ray - Wikipedia

    en.wikipedia.org/wiki/Violet_ray

    A violet ray is an antique medical appliance used during the early 20th century to discharge in electrotherapy. Their construction usually featured a disruptive discharge coil with an interrupter to apply a high voltage, high frequency, low current to the human body for therapeutic purposes.

  4. Electromagnetic spectrum - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_spectrum

    The spectrum is divided into separate bands, with different names for the electromagnetic waves within each band. From low to high frequency these are: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. The electromagnetic waves in each of these bands have different characteristics, such as how they are ...

    Used in extremely high-power (terawatt scale), high-energy multiple beam systems for inertial confinement fusion. Nd:Glass lasers are usually frequency tripled to the third harmonic at 351 nm in laser fusion devices. Titanium sapphire (Ti:sapphire) laser 650-1100 nm Other laser Spectroscopy, LIDAR, research.

  7. Pure-tone audiometry - Wikipedia

    en.wikipedia.org/wiki/Pure-tone_audiometry

    Conventional audiometry tests frequencies between 250 hertz (Hz) and 8 kHz, whereas high frequency audiometry tests in the region of 8 kHz-16 kHz. Some environmental factors, such as ototoxic medication and noise exposure, appear to be more detrimental to high frequency sensitivity than to that of mid or low frequencies.

  8. Terahertz radiation - Wikipedia

    en.wikipedia.org/wiki/Terahertz_radiation

    Terahertz waves lie mostly at the far end of the infrared band, the longest ones in the microwave band. Terahertz radiation – also known as submillimeter radiation, terahertz waves, tremendously high frequency [1] (THF), T-rays, T-waves, T-light, T-lux or THz – consists of electromagnetic waves within the International Telecommunication Union-designated band of frequencies from 0.1 to 10 ...

  9. Bioinstrumentation - Wikipedia

    en.wikipedia.org/wiki/Bioinstrumentation

    Bioinstrumentation is a new and upcoming field, concentrating on treating diseases and bridging together the engineering and medical worlds. The majority of innovations within the field have occurred in the past 15–20 years, as of 2022. Bioinstrumentation has revolutionized the medical field, and has made treating patients much easier.
