What must the technologist ensure when aligning the x-ray tube?

The tube is lined up with the image receptor

Which type of image receptor uses digital cassettes that are processed to create images?

Computed Radiography (CR)

What is the purpose of the control panel in a radiographic system?

To select exposure factors and initiate exposure

What is the typical SID used in X-ray imaging?

What effect does a smaller collimation field have on patient exposure?

It reduces patient exposure

What is one major advantage of Digital Radiography (DR)?

Images appear immediately on the computer console

What does the term 'collimation' refer to in radiographic imaging?

The process of limiting the size of the x-ray beam

What is the role of the radiographer in relation to the equipment?

To manipulate x-ray equipment safely and effectively

In which of the following machines is real-time imaging performed?

Fluoroscopy machines

What is the significance of patient positioning during radiographic procedures?

It ensures the correct anatomy is imaged appropriately

What does SID stand for in radiographic terms?

Source-to-Image Distance

What is the primary function of the X-ray tube?

To produce x-rays

For patient safety, why is it important to use lead-lined barriers?

To protect against unnecessary radiation exposure

What type of radiographic table allows for height adjustment?

Adjustable table

What type of imaging does Sonography use?

Sound waves

What does OID stand for in radiographic terms?

Object-to-Image Distance
