#AI Identifies #FattyLiverDisease Using Chest #XRays

> Researchers trained the #deepLearning algorithm on 6,599 chest X-ray images from 4,414 patients, using controlled attenuation parameter scores as ground truth measures of #liver fat.

> This groundbreaking research opens up new avenues for early detection of this increasingly prevalent condition, which statistics suggest affects nearly one in four people globally.

Anyone else remember the shoe-fitting fluoroscope aka Pedoscope? My medically trained parents would never let the shoe shop assistant X-ray my feet while trying on new shoes, much to my childish disgust. Of course they were 100% correct. From the perspective of the 21st century it seems bizarre that radiation could be served up by untrained operators to members of the general public. The past eh? #shoes #xrays #radiation

The hospital app has the x-rays available now, so I got the one after my previous surgery and the one from last week. I used AI to describe the images, and I'll give the persona details here.
The image with the mesh and all the screws was from the surgery in September 2021. The one with the big cup and two bits of screws was the one from the 14th of this month.

X-RAYS AND ENERGY

X-rays have much higher energy and much shorter wavelengths than ultraviolet light, and scientists usually refer to x-rays in terms of their energy rather than their wavelength. This is partially because x-rays have very small wavelengths, between 0.03 and 3 nanometers, so small that some x-rays are no bigger than a single atom of many elements.a series of 12 x-ray images showing the various level of activity on the Sun.

Our Sun's radiation peaks in the visual range, but the Sun's corona is much hotter and radiates mostly x-rays. To study the corona, scientists use data collected by x-ray detectors on satellites in orbit around the Earth. Japan's Hinode spacecraft produced these x-ray images of the Sun that allow scientists to see and record the energy flows within the corona.

TEMPERATURE AND COMPOSITION

The physical temperature of an object determines the wavelength of the radiation it emits. The hotter the object, the shorter the wavelength of peak emission. X-rays come from objects that are millions of degrees Celsius—such as pulsars, galactic supernovae remnants, and the accretion disk of black holes.

From space, x-ray telescopes collect photons from a given region of the sky. The photons are directed onto the detector where they are absorbed, and the energy, time, and direction of individual photons are recorded. Such measurements can provide clues about the composition, temperature, and density of distant celestial environments. Due to the high energy and penetrating nature of x-rays, x-rays would not be reflected if they hit the mirror head on (much the same way that bullets slam into a wall). X-ray telescopes focus x-rays onto a detector using grazing incidence mirrors (just as bullets ricochet when they hit a wall at a grazing angle).

NASA's Mars Exploration Rover, Spirit, used x-rays to detect the spectral signatures of zinc and nickel in Martian rocks. >>science.nasa.gov/ems/11_xrays/

Happy birthday to Wilhem Röntgen (1845-1923), the German physicist who discovered x-rays and earned the Nobel Prize for physics in 1901. I’ve depicted him in this thermochromic portrait at work, studying this mysterious, newly discovered, invisible form of light, based on a photograph of him in his lab, using a Crookes tube to produce x-rays. The form of the print mimics the nature of his discovery -
