Why is a minimum SID of 72 inches used?
|
To decrease magnification of the heart and increase recorded detail.
|
|
Why do you examine patients in the upright position?
|
1) The diaphragm is at its lowest point.
2) Air or fluid levels are seen. 3) Engorgement of the pulmonary vessels is also avoided. |
|
How far should the upper border of the IR be above the relaxed shoulders?
|
1 1/2 to 2 inches
|
|
On a PA what should be centered to the midline of the IR?
|
The midsagittal plane of the patient's body
|
|
What do you do with the chin?
|
Extend it upward so that it does not interfere with the xray.
|
|
Why do you flex the arms and rest them on the back of the hips?
|
This rotates the scapulae laterally so that they are not superimposed over the lungs.
|
|
What do you do with the shoulders?
|
Depress and rotate them forward to postition them below the lung apices.
|
|
Where should the CR be located?
|
Perpendicular to the center of the IR. The CR should enter at the level of T7.
|
|
What ways will the lungs expand?
|
Transversely
Anteroposteriorly Vertically |
|
On what breath is the exposure taken?
|
The second breath on full inspiration.
|
|
How many ribs should show above the diafrom the diaphragm?
|
ten
|
|
What part of the lungs should show in a radiograph?
|
From the apices to the costophrenic angles.
|
|
Sternal position
|
Make sure there is no rotation.
Sternal of the clavicles equidistant from the vertebral column. |
|
Scapula position
|
Scapulae projected outside the lung fields.
|
|
In a lateral projection, what should be parallel with the IR?
|
midsagittal plane
|
|
In a lateral projection, where should the coronal plane be?
|
Perpendicular to the IR and centered with the midline of the grid
|
|
On a lateral, where should the CR enter the patient?
|
On the midcoronal plane at the level of T7
