Detail Flashcards
directly impact the sharpness or detail of the image
Focal spot size
produces sharper more detailed images by reducing the size of the penumbra
smaller focal spot
results in less detailed image dur to an increase in the penumbra
larger focal spot
increasing the SID
improves immage detail by reducing magnification and the penumbra
produces a sharper image as the xray photons travel over a greater distance resulting iness geometric unsharpness
Increased SID
increase geometric unsharpness and magnification reducing image detail
decreased SID
decreasing the OID
improves mage detail by minimizing magnification and geometric distortion
produces a sharper image as the object is closer to the image receptor reducing the penumbra
decreased OID
result in increased magnification and geometric unsharpness reducing detail
increased OID
the duration of the exposure directly influences motion blur
Time of Exposure
reduces the chance of motion during the exposure resulting in sharper image and improved detail
shorter exposure time
increased the likelihood of motion voluntary or involuntary leading to motion blur and reduced detail
longer exposure time
during the exposure voluntary or involuntary causes blurring which decreased image detail
patient movement
movement like breathing or repositioning by the patient during the exposure
voluntary motion
movement such as heartbeat peristalsis or tremors are harder to control
involuntary motion
motion of the image receptor during exposure creates motion artifacts
image receptor movement
