At the tip of the nebulizer, the liquid is pulled into the gas stream by surface tension along a spout dipping into the gas stream. This allows the gas to impact the liquid, and has the liquid interact in the center of the gas flow where the gas flow speed is highest, producing a better transfer of energy from the gas to the liquid, and ...
In medicine, a nebulizer (American English) [1] or nebuliser (British English) [2] is a drug delivery device used to administer medication in the form of a mist inhaled into the lungs. Nebulizers are commonly used for the treatment of asthma , cystic fibrosis , COPD and other respiratory diseases or disorders.
Spectral imaging is an umbrella term for energy-resolved X-ray imaging in medicine. [1] The technique makes use of the energy dependence of X-ray attenuation to either increase the contrast-to-noise ratio, or to provide quantitative image data and reduce image artefacts by so-called material decomposition.

Bat wing appearance is a radiologic sign referring to bilateral perihilar lung shadowing seen in frontal chest X-ray and in chest CT. [1] [2] The most common reason for bat wing appearance is the accumulation of oedema fluid in the lungs. [3] The batwing sign is symmetrical, usually showing ground glass appearance and spares the lung cortices. [4]
Pneumonolysis, sometimes referred to as plombage, is the separation of an adherent lung from the pleura, to permit collapse of the lung.It was formerly used to treat tuberculosis before effective medications were developed.
Modern 3D Lichtenberg figures or "electrical treeing" in a block of clear acrylic, created by irradiating the block with an electron beam. Actual size: 80 mm × 80 mm × 50 mm (3 in × 3 in × 2 in) Lichtenberg figures are generated by a sliding spark discharge on the flask with a mixture of gases. Structural differences between the "positive ...
The X-rays themselves are produced by the rapid deceleration of electrons in a target material, typically a tungsten alloy, which produces an X-ray spectrum via bremsstrahlung radiation. The shape and intensity of the beam produced by a linac may be modified or collimated by a variety of means.
