Add to cartWhat is medical imaging physics?
Medical imaging physics is a branch of medical physics that focuses on the principles and techniques used in medical imaging, such as X-rays, CT scans, MRI, and ultrasound.

What is the purpose of medical imaging?
The purpose of medical imaging is to visualize internal structures and functions of the human body for diagnostic and therapeutic purposes.

What is the difference between ionizing and non-ionizing radiation?
Ionizing radiation has enough energy to remove tightly bound electrons from atoms, while non-ionizing radiation does not have enough energy to do so.
input text value
How does X-ray imaging work?
X-ray imaging works by passing X-rays through the body, which are then absorbed or scattered by different tissues. The remaining X-rays are detected and converted into an image.
input text value
What is the principle behind computed tomography (CT) imaging?
CT imaging uses X-rays and a rotating gantry to acquire multiple cross-sectional images of the body. These images are then reconstructed into a 3D image using computer algorithms.

What is the main advantage of magnetic resonance imaging (MRI)?
The main advantage of MRI is its ability to provide detailed images of soft tissues, such as the brain, muscles, and organs, without using ionizing radiation.
input text value
How does ultrasound imaging work?
Ultrasound imaging works by emitting high-frequency sound waves into the body and detecting the echoes produced by different tissues. These echoes are then used to create an image.

What is the role of contrast agents in medical imaging?
Contrast agents are substances that are used to enhance the visibility of certain structures or functions in medical imaging. They can be administered orally, intravenously, or through other routes.
