The statement regarding digital fluoroscopy test phantoms that is identified as false is that the phantom does not evaluate spatial resolution. In fact, one of the primary purposes of using a phantom in fluoroscopy testing is to evaluate various performance parameters, including spatial resolution. Spatial resolution refers to the ability to distinguish between closely spaced objects in the image; therefore, phantoms are specifically designed to allow for accurate assessment of this parameter.

Phantoms are typically constructed to simulate human tissue characteristics, allowing for patient-equivalent testing of imaging systems. While they are primarily made of plastic to mimic soft tissue absorption characteristics, it is also common for some phantoms to incorporate materials that represent different tissue densities, such as actual bone, to evaluate imaging performance more comprehensively.

Since the evaluation of spatial resolution is a standard procedure when testing imaging systems, the assertion that the phantom does not evaluate this aspect is incorrect, as spatial resolution is a critical quality control measure in fluoroscopy and digital imaging procedures.
