Final answer:
The carpal tunnel projection of the wrist demonstrates the pisiform bone free of superimposition.
Step-by-step explanation:
The radiographic projection that demonstrates the pisiform bone free of superimposition is the carpal tunnel projection of the wrist. This specialized view is intended to provide a clear image of the carpal tunnel and includes the pisiform, which projects anteriorly forming a bony prominence at the medial base of the hand. The AP oblique view often results in superimposition of other carpal bones, and the carpal bridge projection is designed to view the dorsum of the wrist and is less focused on isolating individual bones like the pisiform.
