Question

Which of the following diagnostic techniques uses X-rays?
A. PET
B. CT-scan
C. ECG
D. Sonography

Answer 1

Hint: An X-ray, often known as X-radiation, is a type of penetrating high-energy electromagnetic radiation. The wavelength of most X-rays ranges from 10 picometers to 10 nanometers, equivalent to frequencies of 30 petahertz to 30 exahertz and energies of 124 eV to 124 eV.

Complete answer:
Images of your internal organs or bones are created during an x-ray examination to aid in the diagnosis of diseases or injuries. A small amount of ionising radiation is emitted (sent out) by a specific machine. To create the image, this radiation flows through your body and is caught on a specific instrument.
The body is exposed to a little amount of ionising radiation. This used to be printed on a specific sheet of film. Nowadays, x-ray exams are more likely to involve the use of a gadget that captures transmitted x-rays and converts them to an electronic image.
Because calcium in bones prevents radiation from passing through, healthy bones appear white or grey. Radiation, on the other hand, easily flows through air voids, making healthy lungs appear black.
A computed tomography (CT) scan is a type of imaging that employs x-rays to create images of body cross-sections.

So, option B is correct.

Note: A typical imaging test that has been used for decades is an X-ray. It allows your doctor to see into your body without the need for an incision. This can aid in the diagnosis, monitoring, and treatment of a variety of medical disorders. Various forms of X-rays are utilised for various purposes.
