Final answer:
Geometric blur will be minimized when the distance between the object being radiographed and the image receptor is decreased since the paths of the x-rays cast smaller shadows, improving image sharpness.
Step-by-step explanation:
When the distance between the object being radiographed and the image receptor is small, geometric blur will be minimized. Geometric blur is affected by three main factors: the size of the focal spot, the distance between the object and the image receptor, and the distance between the focal spot and the object. By reducing the distance between the object and the image receptor, the paths of the x-rays from the edges of the focal spot to the edges of the object cast smaller shadows on the receptor, leading to a sharper image with less blur. This principle is essential in optimizing image quality in radiographic imaging procedures.
