Finally, I want to talk about the radiation dose descriptors.

0:05

As of now, the three main dose descriptors are

0:09

cumulative dose, which is expressed in milligray,

0:12

peak skin dose, also expressed in milligray.

0:15

Third one is the dose area product, expressed in

0:18

milligray times centimeter squared, the area

0:22

adapted.

0:23

Early days, if you say fluoroscopy, generally, they always talk about

0:27

fluoroscopy time.

0:29

And the fluoroscopy time can still be utilized if there is no other

0:33

descriptors are available, and we can estimate the patient dose and so forth.

0:39

Also, these days, every system will

0:42

show dynamically what's the technique used and what is the

0:46

flow, what is the radiation dose accumulating, and

0:50

it is like a meter box. It keeps going

0:53

up as you're doing more and more procedure.

0:56

And you can even set up a threshold to

1:00

stop and allow us to discuss the case.

1:04

This is another dose display, which also shows more trending, like

1:08

what portion of the beam was coming in which direction, which is very helpful for

1:12

estimating patient dose reports and so forth.
