How was the radiology techs technique in taking an cxr?
It is suggested that if the intervertebral space can be discerned thru the heart, the radiology technician
had good technique.
The x-ray had to travel thru (from front (ventrum) to back (dorsum) :
front of patient > skin > muscle > bone > front of heart muscle > blood in heart >
intracardiac structure > back of heart muscle > bone > muscle > skin > back of patient …
and yet one can discern the intervertebral space, technique was good!
