Radiographic Table

A table used for positioning patients during radiographic examinations.

Floating tabletop

A feature that allows the table to move freely in the same horizontal plane.

Bucky tray

A component of the radiographic table that holds the cassette and can be adjusted for positioning.

Wall Unit

A vertical unit that holds the cassette and can be moved up and down for proper alignment.

X-ray tube

A device enclosed in lead housing that generates x-rays for imaging.

Collimator

A device attached to the x-ray tube that adjusts the size of the x-ray field.

Central ray (CR)

The exact center of the x-ray field as the beam passes through the patient.

Source-image receptor distance (SID)

The distance from the x-ray tube to the image receptor.

Accessory Devices

Tools such as lead aprons, lead blockers, sponges, and calipers used in radiography.

Control Panel

The interface used to set technical factors for x-ray exposure.

kVp

Controls the penetration power of x-rays.

mA

Controls the current and number of x-rays produced per second.

Exposure switch

A button that activates x-ray production.

Technique charts

Guidelines for selecting appropriate radiographic techniques.

AEC (Automatic Exposure Control)

A feature that automatically adjusts exposure settings based on the patient's anatomy.

Image receptor buttons

Controls that indicate the placement of the image receptor.

Suggested Procedure for Radiographic Examinations

A step-by-step guide for conducting radiographic exams.

Patient Identification

The process of confirming a patient's identity before the exam.

Protective Lead Shielding

Equipment used to protect patients from unnecessary radiation exposure.
