Position: Facial Bones Reverse Waters The reverse Waters projection is used when the patient cannot extend the neck. It demonstrates the maxillary sinuses and orbital floors. Proper angulation prevents excessive elongation. This projection complements standard Waters. It is frequently tested on ARRT exams.
Position: C Spine Flexion The flexion cervical spine projection evaluates ligament stability and alignment. It is performed only when cleared by a physician. Proper positioning ensures visualization of vertebral motion. This projection complements extension views. It is frequently tested on ARRT exams.
Position: Facial Bones Submentovertex Trauma The trauma SMV projection demonstrates the zygomatic arches and cranial base using a horizontal beam. It is used when the patient cannot extend the neck. Proper centering ensures diagnostic visualization. This projection is essential for trauma imaging. It is recognized on ARRT exams.
Position: C Spine Extension The extension cervical spine projection evaluates posterior ligament integrity. It is performed after trauma clearance. Proper positioning ensures diagnostic quality. This projection complements flexion views. It is a standard ARRT competency.
Position: Orbits Modified Caldwell The modified Caldwell projection demonstrates the orbital rims and floors. The beam is angled less steeply to reduce petrous ridge overlap. This projection evaluates blowout fractures and foreign bodies. Proper positioning prevents distortion. It is a standard ARRT competency.
Position: Orbits Rhese The Rhese projection demonstrates the optic foramen. The head is rotated 37 degrees to align the orbit with the beam. This projection evaluates optic canal pathology. Proper positioning is critical for accurate visualization. It is frequently tested on ARRT exams.
Position: Orbits Lateral The lateral orbit projection demonstrates the orbital walls and soft tissues. It evaluates fractures, foreign bodies, and masses. Proper positioning ensures superimposition of orbital roofs. This projection complements Caldwell and Waters views. It is a core ARRT requirement.
Position: Sinuses Open Mouth Waters The open mouth Waters projection demonstrates the sphenoid sinus through the open mouth. It is essential for evaluating sinusitis and sphenoid pathology. Proper chin elevation and mouth opening are required. This projection complements standard Waters. It is frequently tested on ARRT exams.
Position: Sinuses Transorbital The transorbital sinus projection demonstrates ethmoid and sphenoid sinuses. It uses a horizontal beam to show air fluid levels. Proper positioning prevents orbital distortion. This projection is used in trauma and infection evaluation. It is recognized on ARRT exams.
Position: Sinuses Lateral Trauma The trauma lateral sinus projection uses a horizontal beam to evaluate air fluid levels. It is essential for diagnosing sinus fractures and hemorrhage. Proper positioning prevents rotation. This projection complements AP and Waters views. It is a standard ARRT competency.
