Ultrasound is also limited by its inability to image through air pockets (lungs, bowel loops) or bone. Its use in medical imaging has developed mostly within the last 30 years. The first ultrasound images were static and two-dimensional (2D), but with modern ultrasonography, 3D reconstructions can be observed in real time, effectively becoming ...
The first commercially viable CT scanner was invented by Sir Godfrey Hounsfield in Hayes, United Kingdom, at EMI Central Research Laboratories using X-rays. Hounsfield conceived his idea in 1967. [14] The first EMI-Scanner was installed in Atkinson Morley Hospital in Wimbledon, England, and the first patient brain-scan was done on 1 October ...
The first MRI scanner to be built and used, in Aberdeen Royal Infirmary in Scotland. The history of magnetic resonance imaging (MRI) includes the work of many researchers who contributed to the discovery of nuclear magnetic resonance (NMR) and described the underlying physics of magnetic resonance imaging, starting early in the twentieth century.
Freund's first experiment was a tragic failure; he applied x-rays to a naevus in order to induce epilation and a deep ulcer resulted, which resisted further treatment by radiation. The first successful treatment was by Schiff, working with Freund, in a case of lupus vulgaris.
Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to generate pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields , magnetic field gradients, and radio waves to form images of the organs in the body.
Today, we celebrate the 129th anniversary of the discovery of X-rays. X-rays were first discovered on November 8, 1895. In 1996, Indore became the first city worldwide to celebrate this milestone, by under supervision Dr OP tiwari and Radiology team by Shivakant vajpai, Maan singh choudhary and marking the centenary of this groundbreaking discovery.

Heinrich Rudolf Hertz (1856–1894) proved the existence of electromagnetic radiation. In an 1864 presentation, published in 1865, James Clerk Maxwell proposed theories of electromagnetism and mathematical proofs demonstrating that light, radio and x-rays were all types of electromagnetic waves propagating through free space.
