1. OBJECTIVE
This learning environment aims to familiarize you and instruct you in the correct positioning to perform Upper Limb X-rays.

As part of the activities, you will apply positioning, define the direction of the Center Ray and restrict the beam to the area of ​​interest.


At the end of this experiment, you should be able to:

Perform correct positioning;

center and delimit the study area and the Image Receiver or Central Ray;

direct the radiation beam to the area of ​​interest;

restrict the x-ray beam;

use breathing techniques to better visualize the structure, when necessary.

2. Where to use these concepts?
Knowing the positions is not only a prerequisite for developing the technologist's skills and abilities, but also becomes indispensable. Furthermore, correct application is part of a technologist’s daily life.


3. The experiment
This experiment will use the following items: x-ray machine, bucky, image receptor and patient in an upright or supine position.


4. Security
In this practice, the use of gloves, a lab coat and a dosimeter are essential. Although the practice does not generate any type of risk for the student, this protective equipment is essential for the CDI environment. The glove will prevent any possible cuts or contamination with agents harmful to the skin, the lab coat protects the body as a whole, and the dosimeter is responsible for monitoring the radiation dose acquired by the professional.


5. Scenario
The experiment environment presents the x-ray equipment and its components: operating console, high voltage transformer, protective housing, collimator, grid. In addition to a wall bucky or bucky table and x-ray film. You must select and use them in order to guarantee the correct execution of the positioning.
