What are real images in panoramic imaging?

• A. Images formed outside the focal trough
• B. Objects between the center of rotation and the receptor that appear sharp
• C. Objects behind the center of rotation
• D. Ghost images only

Answer: (B)

In panoramic imaging, whether an image on the receptor is sharp depends on where the object sits relative to the center of rotation. Real images occur when a structure lies between the center of rotation and the receptor because the X-ray rays project directly onto the receptor plane, forming a true, in-focus image that the film records. If the object is behind the center of rotation, its projection does not land as a proper image on the receptor and tends to be blurred or appear as a ghost/virtual image rather than a clear, real image. This is why objects between the center of rotation and the receptor are described as forming real, sharp images on the panoramic radiograph.
