When is a Large Focal Spot used on an image and what does it affect? | Used when a high intensity x-ray beam is required for thicker anatomy (over 10 cm) requiring less detail (extremity) - It effects Spatial resolution - the amount of blur and unsharpness on an image) |
When is a grid used and what purpose does it serve? 1. 2. 3. | 1. On a part that measures over 10 cm 2. Reduces scatter or noise on an image 3. reduces patient dose |
When is a KUB ordered by a Radiologist? | Image of the Kidney, Ureters, and Bladder when the Urinary System is to be evaluateds |
What is a KUB Abdomen? | A general survey of the Abdomen to include shadows of the Kidneys and Symphysis Pubis to ensure the area of the Urinary Bladder is visualized |
What is magnification? How is it corrected? | enlargement of an objects size and shape - which is equal to image size/object size - SID/OID - increase SID and decrease OID |
What is distortion and how is it corrected? | A misrepresentation of an objects size and shape - due to divergence of the xray beam - correct by making sure part is centered to the CR beam, the focal spot is the center of the part to be xrayed and the Center of the Central Ray |
