M6 L6 Fluoro quality and QC

Spatial resolution

ability to image small
objects that have high subject contrast

Contrast resolution

abliity to distinguish between and image body parts with similar tissue density

temporal resolution

ability of a systemt o resolve an image within a time frame

the faster the system obtains the image the x spatial resolution

less

what is prone to lag

slow system
