Xray Flashcards
Branch of medicine that uses imaging technology to diagnose and treat disease.
Radiology
variety of imaging procedures to see the inside of the body, and diagnose the patient’s conditions.
Diagnostic Radiology
diagnose and treats patients using image-guided, minimally invasive techniques.
Interventional Radiology
prescribe and oversee each cancer patient’s treatment plan.
Oncologic Radiology
Two people involved in Radiology.
Radiologist and Radiographers
Medical professionals tasked with operating highly specialized scanning machines.
Radiographers
Medical doctors that specialize in diagnosing and treating disease using medical imaging.
Radiologist
Uses high-frequency sound waves.
Ultrasound
Uses magnetic field and radio waves.
Magnetic Resonance Imaging (MRI)
German physicist, discovered x-ray.
Wilhem Conrad Roentgen
when did Wilhem Conrad Roentgen discovered x-ray?
Nov. 8, 1895
a form of ionizing electromagnetic radiation.
X-Rays
Situated in a protective housing that provides solid, stable, and mechanical support.
X-Ray Tube
Help dissipate heat away from tube, protecting it from thermal damage.
Cooling fans
Provides support, serves as an electrical insulator and thermal cushion.
Lead-lined
Draws heat away from the tube.
Oil bath
Is an electronic vacuum tube that controls the number and speed of the accelerated electrons independently.
Glass Tube
A negative terminal of the x-ray tube that is composed of a filament and a focusing cup.
Cathode
A positively charged target made of tungsten, set at angle to direct x-ray photon bean own towards the patient.
Anode
Two types of anode terminals.
Stationary Anode and Rotating Anode
2 Types of radiation
Bremsstrahlung and Characteristic Radiation
Displays radiographic image.
Placed within the cassette and exposed to x-ray.
X-ray Film
Functions of Films
Image Recording, Display, and Storage
A rectangle or square plastic or metallic container used to hold x-ray films and intensifying screens.
Cassette
A type of electromagnetic radiation that emanates from within the nuclei of radioactive atoms and are used to image the distribution of radiopharmaceuticals.
Gamma Rays
A type of electromagnetic radiation that produced in detecting x and gamma rays; used for the observation and interpretation of images.
Visible Light
A type of electromagnetic radiation that produced outside the nucleus and used in radiography and computed tomography.
X-rays
A type of electromagnetic radiation used as transmission and reception signal for magnetic resonance imaging (MRI)
Radiofrequency
A type of x-ray radiation that has higher frequency that the near-ultraviolet region of spectrum.
This type of radiation can alter molecules and cause harm.
Ionizing Radiation
A type of radiation that has low-energy and does not remove electrons from atoms.
Non-Ionizing Radiation
Two types of x-rays
Non-mobile and Mobile
Provide an appropriate standard of protection for man without limting beneficial practices of radiation exposure.
Radiation Protection
3 main principles of Radiation Protection.
Justification, Optimization of Protection, and Dose Limitation.
Was the primary body created to advance for the public to benefit the science of radiological protection.
ICRP
An estimate of the uniform, whole body equivalent dose that would produce same level of risk for adverse effects that results from the non-uniform radiation.
Effective Dose
What is the unit use for Effective Dose?
Sievert (Sv)
Describes the amount of radiation travelling through the air
Unit of Exposure
Energy deposited in a tissue by the radiation beam per unit mass of matter.
Absorbed Dose
What is the unit use for Unit of Exposure?
Roentgen (R) and Coulumb/kilogram (C/kg)
What is the unit used for Absorbed Dose?
Gray (Gy)
What is the recommended of radiation for people working with radiation every five years?
0.10 Sv
Annual dose limit for radiation workers.
20 mGy
typical dose for CT scan of chest?
10 mGy
a type of effect that is due to cell changes (DNA) and proliferation towards a malignant disease.
Stochastic Effect
a type of effect that is due to cell killing and have a close threshold-typically several Gy.
Deterministic Effects
It is used as a protection for radiation.
Lead Shields
In this view, the patient is able to stand or do an upright positioning.
PA View
In this view, patient is not able to stand up or position in an erect, upright positioning.
AP View
This type of view is used to confirm a particular abnormality that is seen in the initial chest PA/AP view.
Lateral View
This type of view is used when a suspicious density is seen in the upper lung area of the chest PA view.
Apicolordotic View
This type of view is used to confirm if the density seen in the chest PA/AP view is fluid or not.
Lateral Decubitus View
