Standard Thoracic Views Flashcards
AP Thoracic: Patient Measurement
Anterior to Posterior, mid-sternum, with the calipers placed over the shoulder
AP Thoracic: Grid
Yes, stationary or moveable
AP Thoracic: Source to Image Distance
40”
AP Thoracic: Tube Tilt
None
AP Thoracic: Image Receptor Size
7 x 17” or 14” x 17” in portrait orientation
AP Thoracic: Patient Positioning
Patient stands with his or her thoracic spine touching the grid and the spine/sternum centered to the midline of the grid
AP Thoracic: Central Ray Position
Central ray will be located at approximately C7
(Top of the image receptor is positioned approximately 2” above the C7 spinous process)
AP Thoracic: Collimation
17” Vertically and 6-8” horizontally, wider if severe scoliosis is suspected
AP Thoracic: Filter
Tube is filtered from the top down to the mid-sternum
AP Thoracic: Marker Placement
Directly on the image receptor, in one of the lower corners of the collimation field
AP Thoracic: Breathing Instructions
Suspended full inspiration and motion (“Take a deep breath in and hold completely still”)
Lateral Thoracic: Patient Measurement
Laterally, under the arms, at the level of the axillae
Lateral Thoracic: Source to Image Distance
40”
Lateral Thoracic: Tube Tilt
None
Lateral Thoracic: Image Receptor Size
14” x 17”, in portrait orientation
Lateral Thoracic: Patient Positioning
Patient stands w/ side touching grid (If convexity, then should be toward grid) and arms flexed to 90 degrees, out of the collimation field (Can use T-Bar)
Lateral Thoracic: Central Ray Position
About C7 (top of image receptor 2” above C7)
Lateral Thoracic-Collimation
17” vertically and 6-10” horizontally, wider if hyperkyphosis is suspected
Lateral Thoracic: Filter
The tube may be filtered from the bottom up to the axillae
Lateral Thoracic: Marker Placement
Directly to the image receptor, within one of the corners of the collimation field without superimposing any anatomy
Lateral Thoracic: Breathing Instructions
Suspended full inspiration and motion (“Take a deep breath in and hold completely still)
To blur the ribs, the patient may deeply ______ and slowly ______ as the exposure is taken
Inhale; exhale
