Final answer:
The intervertebral foramina of the thoracic spine can be visualized using a coronal plane angled at 45 degrees to the imaging receptor (IR).
Step-by-step explanation:
The intervertebral foramina of the thoracic spine are demonstrated with a. Coronal plane 45 degrees to the IR.
A coronal plane is a vertical plane that divides the body into front and back portions. When the coronal plane is angled at 45 degrees to the imaging receptor (IR), it allows visualization of the intervertebral foramina.
For example, in a thoracic spine X-ray, the coronal plane angled at 45 degrees to the IR would show the sides of the thoracic vertebrae and the spaces between them, where the intervertebral foramina are located.
