In order to minimize involuntary motion:
- A- fine focus is recommended
- B- broad focus is recommended
- C- the use of short exposure time is essential
- D- b&c
The answer to minimize involuntary motion is C. the use of short exposure time is essential.
Here's why:
Involuntary motion, such as breathing or peristalsis, can blur the image on an X-ray. The longer the X-ray beam is exposed to the patient, the higher the chance of capturing these movements, resulting in a blurry or unclear image.
Therefore, to minimize involuntary motion and ensure a sharp image, using a short exposure time is crucial. This means the X-ray beam is turned on for a very brief period, capturing the static anatomy before any significant movement can occur.
Summarizing the options:
Here's a table summarizing the options and their impact on involuntary motion:
|
Option |
Impact on
Involuntary Motion |
|
A. Fine
focus |
No direct
impact. Fine focus collimates the X-ray beam, improving image sharpness but
not directly affecting exposure time. |
|
B. Broad
focus |
May
increase involuntary motion blur. A broader beam covers a larger area,
potentially capturing more movement during longer exposure times. |
|
C. Short
exposure time (correct) |
Reduces
involuntary motion blur. Shorthandening the exposure time limits the
opportunity for movement to affect the image. |
|
D. B &
C |
Not
accurate. While broad focus could worsen blur, its main purpose is different.
Short exposure time is the key factor in minimizing involuntary motion. |
Additional Tips:
Here are some additional tips for minimizing involuntary motion during X-ray imaging:
- Proper patient positioning:
Ensure the patient is comfortable and well-supported to minimize movement.
- Breath holding instructions:
Ask the patient to hold their breath briefly during image acquisition.
Pain management: Address any pain or discomfort that might cause the patient to move involuntarily.
- Immobilization devices:
Utilize straps, cushions, or other tools to stabilize specific body parts, if necessary.
By using short exposure times and implementing these additional strategies, healthcare professionals can achieve sharp and clear X-ray images that accurately represent the patient's anatomy.
