CAMRT Radiography Practice Exam 2025 – Comprehensive Test Prep

Question: 1 / 1100

What describes the orientation of the central ray in a mammography exam for the mediolateral oblique projection?

Angled 45 degrees

Perpendicular

In mammography, specifically for the mediolateral oblique projection, the central ray is positioned perpendicular to the imaging receptor. This orientation is crucial because it ensures optimal visualization of the breast tissue, enabling better assessment for potential abnormalities.

When the central ray is perpendicular, it helps in providing a standardized approach to imaging, which enhances the clarity and detail of the mammogram. This alignment minimizes distortion and improves the accuracy when interpreting the images. The other possible orientations, such as being angled or parallel, would not provide the same level of detail or may introduce artifacts, thereby compromising the exam's effectiveness in diagnosing breast conditions.
