Exam 1: Terminology, Positioning, and Imaging Principles

Which of the following body systems helps to regulate body temperature?

A projection in which the CR skims a body part is termed:

Which of the following radiographic studies would best benefit by applying the anode heel effect?

MATCHING Select the correct definition for the terms listed below.(Use each choice only once.) -Turn or bend hand and wrist toward radius

Exposure indicator is a numeric value that is representative of the level of exposure the image receptor has acquired.

Tangential and axial projections are the same type of projection.

Which term describes lying down in any position?

Range of exposure intensities that will produce an acceptable image is the definition for exposure:

MATCHING Select the correct definition for the terms listed below.(Use each choice only once.) -Rotation of hand with palm down

The intensity of light that represents the individual pixels in the image on the monitor defines:

A patient is lying on her back.The x-ray tube is horizontally directed with the CR entering the right side of the body.The image receptor is adjacent to the left side of the body.What is the radiographic position?

A digital storage and image management system defines a:

What type of tissue covers internal and external surfaces of the body?

Using a table Bucky device will increase magnification of the anatomy as compared with performing the same study on the tabletop.

Where should a personnel dosimeter be worn during fluoroscopy?

What is the general term for a position in which the long axis of the body is angled in relationship to the image receptor rather than the central ray (e.g.,special chest projection)?

The intensity of the x-ray beam is greatest under the anode as defined by the anode heel effect.

When viewing a CT (computed tomography)or MRI (magnetic resonance imaging)image,the patient's right is facing the viewer's left.
