A substance that consists of only one type of molecule is called a chemical compound. In good all round condition. Matter is defined as anything that occupies space and has shape or form. Binding energy is higher for shells closer to the nucleus. Despite this, some understanding of the basic physics used in ultrasound is needed for optimal creation and interpretation of an ultrasound image. The comprehensive text is further enhanced by nearly 350 radiological images, diagrams and tables. Radiography Essentials - Chapter 4 (Basic Physics for Radiology) STUDY. Scientists have determined that atoms may be made up of nearly 100 different subatomic particles, but only three basic particles concern us here. Opposite charges attract one another, seeking a neutral state. Radiation is the transmission of energy via waves or particles. The mass number of the element is the combined total of the protons and neutrons in the nucleus. X-Ray Interaction with Matter - X-ray generation, attenuation, dose, and image contrast.
