Study Notes
Positioning of Chest Radiograph
The proper positioning of the patient is crucial for obtaining high-quality chest radiographs. This article will discuss the key aspects of patient positioning, central ray placement, anatomy visualization, and common positioning errors.
Patient Positioning
Proper patient positioning is essential for achieving accurate and clear chest radiographs. The following steps should be taken to position the patient correctly:
- The patient should remove clothes from the waist up and put on a hospital gown.
- Remove any jewelry, such as necklaces or earrings, and tie hair up on top of the head if necessary.
- Ensure that the patient is standing evenly on both feet.
- Both shoulders should be rolled forward and downward, with the chest radiograph well centered.
- The patient's arms should be placed on the hips with the palms facing out, and the shoulders should be rolled forward.
Central Ray Placement
The central ray is a crucial component of chest radiograph positioning. For a standard two-view chest radiograph, the central ray is centered at the level of the T7 vertebra. For a lateral decubitus chest radiograph, the patient lies on their side (either right or left) with the arms above their head and the chin up. The central ray is centered at the level of the T7 vertebra, and the rotation should be approximately 45 degrees for oblique radiographs.
Anatomy Visualization
Chest radiographs allow for the visualization and assessment of the chest wall, mediastinum, heart, great vessels, central airways, and lung fields. The following anatomical structures can be visualized in a standard chest radiograph:
- Vertebral bodies, intervertebral disc spaces, articular pillars, spinous processes, and anterior and posterior arch of atlas
- Ribs below the diaphragm
- Lung fields and the heart shadow
Common Positioning Errors
Some common positioning errors that can occur during chest radiographs include:
- Incorrect patient positioning, such as the patient not being properly aligned or seated
- Inadequate central ray placement, leading to distorted anatomy or overexposure of certain areas
- Incorrect hand-spread method being used, which can result in errors in locating the central ray
By understanding and addressing these common positioning errors, radiographers can improve the quality of chest radiographs and ensure accurate interpretations.
In conclusion, proper patient positioning, central ray placement, and anatomy visualization are essential components of obtaining high-quality chest radiographs. By following the guidelines outlined in this article and being aware of common positioning errors, radiographers can ensure accurate and clear images for diagnosis and treatment planning.
