Fluoroscopy is best defined as:
A static X-ray imaging technique
A real-time dynamic imaging technique
A nuclear imaging method
A photographic imaging process
The main function of the X-ray generator in fluoroscopy is to:
Display images
Convert light into electrical signals
Supply high voltage and tube current
Absorb scattered radiation
Which generator type is commonly used in fluoroscopy to improve efficiency and reduce patient dose?
Single-phase generator
Three-phase generator
High-frequency generator
Capacitor discharge generator
The collimator is positioned:
Above the patient table
Between the patient and image intensifier
Immediately below the X-ray tube
Inside the video camera
Which of the following is NOT a function of the collimator?
Limiting irradiated area
Reducing scatter radiation
Increasing patient dose
Improving image contrast
Filtration in fluoroscopy primarily removes:
High-energy photons
Low-energy X-ray photons
Scattered radiation
Visible light photons
Which material is commonly used for added filtration?
Copper
Lead
Aluminum
Tungsten
The patient table used in fluoroscopy is made of radiolucent material mainly to:
Increase image contrast
Support heavy equipment
Allow unobstructed X-ray passage
Reduce examination time
Image contrast in fluoroscopy is produced because:
X-rays are reflected by tissues
Different tissues attenuate X-rays differently
All tissues absorb X-rays equally
X-rays are converted directly to light
The grid in fluoroscopy is placed:
Between the X-ray tube and patient
Between the patient and image intensifier
Inside the X-ray generator
On the monitor screen
