RCIS Practice Test 2025 – All-in-One Exam Prep

The lateral view exposes the operator to the greatest amount of radiation due to the positioning and orientation of the X-ray beam in relation to the patient's body. In the lateral view, the operator is positioned closer to the primary radiation source, which results in a higher dose of scatter radiation. This positioning is critical because X-ray machines emit radiation in a direction where the lateral view can capture necessary images of anatomical structures while maximizing exposure to the operator.

In contrast, the frontal view typically has the operator positioned away from the path of the beam and focuses on a direct, straight-line image which generally requires less exposure. The oblique view, while it may involve some angular positioning, is still designed to minimize exposure through optimized techniques. The axial view, while potentially exposing the operator, is usually managed in such a way that helps reduce direct radiation exposure through strategic positioning.
