iphone LIDAR for detecting cavities ?

Hi not talking about dental issues here...
Already using the LIDAR feature on my iphone 15 pro max for mapping interiors of archeological structures.
Can LIDAR be used in order to detect cavities (i.e. hollow spaces) not immediately visible to the eye ?
F.ex. a space behind an obstructed entrance or door.
Or can this be done through another app (with appropriate hardware addon)?
Basically something doing the job of an GPR.
