Radiology is called the specialty of medicine that uses the imaging technologies of internal organs or other parts of the body to diagnose and many times treatment of diseases.
Imaging was first achieved with X-rays (ionizing radiation) discovered by Wilhelm Röntgen in 1895, so their application to medicine was named “radiology”.
Sonography – Ultrasound is a medical imaging method that produces images of human body parts using ultrasounds.
Ultrasonic imaging device is a device with an architecture similar to that of the computer that receives signals from a transceiver, processes them, and converts them to images in black and white or color form. The transceiver is the peripheral component of the machine that sends ultrasound to the body in the direction that the examiner defines and simultaneously accepts their reflections and turns them into a picture.
Each body tissue has special behavior in ultrasound and thus reflects, refractive, or “absorbs” a different amount of waves than it accepts. So the computer after receiving reflections and knowing the number of waves sent yields a color or a shade of gray on each tissue and displays them on screen like images. These images are studied by the examiner and in turn export diagnostic conclusions.
