PA: RAO
AP: LPO

34
Q

zygapophyseal joints at at 45° angle the right joints are best demonstrated with what?

35
Q

the mid coccyx is at the level of about what landmark?

39
Q

Xiphoid Tip is approx at what level

A

T9-T10

40
Q

AP projection of lumbar is taken with knees flexed, why?

reduce lordosis of lumbar spine

41
Q

Gonadal shielding on males must be placed?

A

top edge is at lower margin of pubic symphysis

42
Q

the Prone position for the lumbar places the lumbar spine?

25-30° less dose

44
Q

what is the disadvantage of the PA of lumbar vertebrae

A

increased OID especially on large patients

45
Q

Why would you increase SID for lateral?

A

reduce magnification
