Future studies could compare retake rates between these image receptors to determine if one results in a higher retake rate so that educational resources can be directed to address challenges associated with specific devices.
(16) Adjustable collimators limit the x-ray beam to the size of the active image receptor and ideally to the region of interest.
surface of the image receptor required to produce a single image b.
The patient's sternum should be placed along the edge of the image receptor, with the arm on the side being imaged resting atop the handlebars or raised over the top of the image receptor.
The image receptor should be against the chest wall superior to the breast.
To position the breast, the mammographer centers the breast's superior surface on the image receptor, holding the breast up in position while compression is applied.
If necessary, the x-ray tube assembly can be angled upward 5 [degrees] to ensure contact between the lateral portion of the breast and the image receptor. The breast should be held in position while compression is applied.
The image receptor is raised so that it includes the superior aspect of the head of the humerus.
* Check the height of the image receptor. It should be lowered if necessary.
The inferior surface of the breast is then positioned onto the image receptor, much like the positioning for an upright CC projection.
With the filter positioned between the patient and the image receptor, entrance surface exposure does not differ with or without the filter because x-rays are compensated after passing through the patient.
