RADR 1411 Chapter 6 Exam 2 Review (90 Questions) – Foot & Ankle Positioning, kVp Techniques, CR Angles | 2026 – Radiologic Technology

This document contains a focused set of approximately 90 exam-style questions and correct answers for RADR 1411 Chapter 6 Exam 2, covering foot and ankle radiographic positioning and imaging techniques. It includes key anatomical structures such as the tarsal bones (calcaneus, talus, cuboid, navicular, and cuneiforms), along with detailed breakdowns of projections including AP, oblique, lateral, weight-bearing, and calcaneus views. The structured Q&A format makes it highly effective for mastering positioning concepts and preparing for practical exams. The material provides in-depth coverage of exposure techniques, including specific kVp ranges for various foot and ankle projections, as well as adjustments required for casts (plaster and fiberglass). It also explains central ray (CR) placement, angulation, and anatomical landmarks for each projection, ensuring students understand both theory and positioning accuracy. For example, the tables across pages 5–6 outline precise CR locations such as the base of the 3rd metatarsal and medial malleolus, which are critical for correct image acquisition. Additionally, the document highlights anatomical evaluation criteria for each projection, including joint visualization (tibiotalar joint, sinus tarsi), superimposition rules, and image quality indicators. It also reinforces key joint anatomy such as the talocalcaneal joint and sinus tarsi, helping students connect positioning techniques with anatomical outcomes. This resource is ideal for students enrolled in Radiologic Technology, Diagnostic Medical Imaging, or Radiography programs. It is particularly useful for courses such as RADR 1411 – Radiographic Procedures I, Positioning and Anatomy, or Extremity Imaging offered at universities, community colleges, and allied health institutions. It is especially beneficial for first-year radiography students preparing for positioning labs, practical exams, or competency check-offs. The content aligns closely with standard textbooks such as Merrill’s Atlas of Radiographic Positioning and Procedures by Jeannean Hall Rollins and Radiographic Imaging and Exposure by Terri L. Fauber, making it an excellent supplementary study guide for both theoretical understanding and hands-on application.
