What best describes the relationship of the mandibular condyles in a properly performed SMV projection?

In a properly performed Submentovertex (SMV) projection, the mandibular condyles are positioned at equal distances laterally from the skull. This alignment is essential for achieving accurate imaging of the structures within the skull, particularly in assessing the anatomy of the mandible and the temporomandibular joint (TMJ).

The SMV projection is specifically designed to visualize the base of the skull and the relationship of the mandible to the cranium. In this projection, the patient's head is extended backwards, allowing the X-ray beam to be directed under the chin and through the vertex of the skull. When the mandibular condyles are equally distanced from the midline of the skull, it indicates that the patient's positioning is correct, ensuring that there is no tilt or rotation that could distort the image.

The other options may suggest different positional relationships that do not accurately reflect the intended results of this specific projection. Thus, understanding the distinct positioning of the condyles in relation to the skull is crucial for achieving diagnostic quality images in cranial imaging.
