If you can discern the intervertebral space thru the heart on film , the CXR technique was good!

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!
