1. FILM ARTIFACTS

2. ARTIFACTS: AN UNWANTED DENSITY ON THE FILM

3. Exposure Artifacts Motion Improper patient position
Wrong screen-film match
Poor film/screen contact
Double exposure
Warped cassette
Improper grid position

5. PATHOLOGY ?

6. pneumonia

7. GRIDS CAN LEAVE LINES ON THE IMAGE

8. POOR
DETAIL
GOOD DETAIL

9. Blurring of image due to patient movement during exposure.

11. When there is a space between the contact of the film to the intensifying screens, a larger amount of light is allowed to reach the film – causing “more density” on fim

12. Lack of contact between film and cassette can cause “blurring” of the image

13. Artifacts - Types

57. What do you
See?
2 exposures

58. Does this show good detail?
Is all of the anatomy present?
How is the density / contrast?

59. Does this show good detail? Is all of the anatomy present?
YES
Is all of the anatomy present?
No (part of the little finger is not seen)
How is the density / contrast?
Density – a little “light” underexposed
Contrast is good

60. Which image shows “better” detail
Slower speed
Faster speed

61. CR - ? Which shows “better detail”
8 x 10 cassette x 17 cassette

62. See anything wrong with this image?

63. Contrast? What influences this? (kVp in f/s)

64. Discarded x-ray film used to make ♫ records ♫

65. Collimation – reducing the size of beam helps to improve the image, and reduce the dose to the patient
