RADIOLOGY : A Historic Perspective

Radiation

Is imitied energy Examples: Gamma Ray, X-ray, Ultraviolet, Visible, Infrared, Microwave, Radio

Ionizing Radiation

No safe doze Can be natural or man-made Much of what we know about radiation came from the atomic bombs Las Vegas played a role

Electromagnetic Radiation

Energy that travels through space as electric and magnetic waves. Examples include X-rays, gamma rays, visible light, microwaves, and radio waves.

Nuclear Radiation

Radiation released from the nucleus of an unstable atom during radioactive decay. Examples include alpha particles, beta particles, and gamma rays.

Acute Exposure

A large amount of radiation received over a short period of time.

Physical Science X-Ray

The study of the physical principles involved in producing and using X-rays.

Electricity

Provides the energy needed to produce X-rays by accelerating electrons.

Vacuums

Prevents electrons from colliding with air molecules inside the X-ray tube.

Image Recording Materials

Materials that capture and record the X-ray image, such as film or digital detectors.

Discovery of X-Rays

Wilhelm Conrad Roentgen discovered X-Rays on November 8 ,1895 Working with crookes vacuum tube and experimenting with cathode rays

Radiograph

X-Ray image as viewed on a monitor after acquisition (used to be film)

Radiography

The use of X-rays to create images of the inside of the body.

Radiographer

A healthcare professional who operates X-ray equipment and produces diagnostic images.

Radiologists

Physicians who interpret medical images to diagnose and help treat diseases and injuries.

Fluoroscope

In 1896 Thomas Edison developed it

Clarence Madision Dally

Assistant and longtime friend of Edison Died of radiation-induced cancer in 1904 at 39 years old Became the first American radiation fatality

Respiratory System

Why does CPR work?

The rescuers exhaled air is 17% oxygen and 4% CO2 100% oxygen could be dangerous 21% oxygen is normal air room

Parts of the Respiratory System

Nasal Cavity (Paranasal Sinuses, Nostril) Oral Cavity Pharynx Larynx Epiglottis Trachea Carina of Trachea Left (main and primary) and Right bronchus Bronchi Alveoli Left and Right lung Parietal Pleura Visceral Pleura Diaphragm Ribs

Chest X-ray is the most performed why?
