3. as an es mate from ESE
4. directly from the beam
3. as an es mate from the ESE
The Privacy Rule is meant to ensure that there is/are
1. security of electronic personal health informa on
2. standardiza on of electronic pa ent health data
3. limits PHI to a "need to know.." basis to carry out medical treatment
4. all the listed answers
4. all the listed answers
To provide illumina on stability of the virtual image during fluoroscopy, most modern units will

d. vigneIng
3. quantum noise
When wearing a "film badge" as a personnel monitoring device, it must be posi oned
1. at waist level
2. at collar level
3. under the protec ve apron
4. outside the protec ve apron
b. 2 and 4
Which of the following are considered to be advantages of using a film badge for radia on
monitoring
