M6 L7 Fluroroscopic Safety

last image hold feature

last fluroroscopic image obtained remains on the image

what is good about the last hold feature

reduce dose to patients because the docotor can refer to the image instead of doing more fluoro

what mode should we use when doing fluorosocpic procedures

intermittent or pulse

what mode shouldnt we use when doing fluorosocpic procedures

continuous

what should the pulse rate be if we use pulsed fluoro

7-8 sec

why do we used intermittent or pulsed fluoro instead of continuous

reduce patient dose

what is a chronometer

timer

what should be close to the paitent

IR

what should be far from the patient

xray tube

what should be the distance in a focal spot to skin for mobile

30 cm

what should be the distance in a focal spot to skin for stationary

38 cm

what protection should we have on when doing fluoro at 100 kV

0.28 pb

what are the protection protocols in fluoro

• must have an apron

• protection gauntlets

• should be done rapidly and at a small size

• physical distance form operation

in a C- arm fluoro, where os the lower potential scatter dose?

side of the patient away from the xray tube

where is generally high scatter when doing a mobile c arm fluoro

xray tube side

where is generally low scatter when doing a mobile c arm fluoro

II side

what happens when the xray tube is over the patient and the II is under

increased dose to the personnel

what is the ideal formation of a II and xray tube in a mobile C arm

the xray tube is under the patient and the II is over
