godswillmywill Position: Tangential Zygomatic Arch The tangential projection isolates one zygomatic arch. It evaluates depressed fractures. Proper rotation and tilt prevent superimposition. This projection complements SMV. It is a standard ARRT competency.
Position: SMV Zygomatic Arches The SMV projection demonstrates the zygomatic arches without superimposition. Proper hyperextension is essential. This projection evaluates depressed fractures. It complements oblique tangential views. It is frequently tested on ARRT exams.
Position: AP Axial Zygomatic Arches The AP axial zygomatic projection demonstrates the arches and zygomatic bones. Proper angulation prevents superimposition. This projection evaluates fractures and deformities. It complements SMV and oblique arch views. It is recognized on ARRT exams.
Position: Lateral Facial Bones The lateral facial bones projection demonstrates nasal bones, maxilla, and zygoma. It evaluates fractures and soft tissue injuries. Proper positioning ensures superimposition. This projection complements Waters and Caldwell. It is frequently tested on ARRT exams.
Position: Modified Waters Facial Bones The modified Waters projection reduces chin extension to better visualize orbital floors. It evaluates blowout fractures. Proper positioning prevents distortion. This projection complements standard Waters. It is a standard ARRT requirement.
Position: Waters Facial Bones The Waters projection demonstrates maxillary sinuses and orbital floors. Proper chin elevation projects petrous ridges below the sinuses. This projection evaluates fractures and sinusitis. It complements Caldwell and lateral views. It is frequently tested on ARRT exams.
Position: SMV Skull The SMV projection demonstrates the cranial base and zygomatic arches. Proper hyperextension is essential. This projection evaluates fractures and cranial base lesions. It complements AP and lateral skull views. It is a recognized ARRT competency.
Position: AP Axial Skull Towne The Towne projection demonstrates the occipital bone and foramen magnum. A caudal angle projects facial bones inferiorly. This projection evaluates fractures and cranial base pathology. Proper positioning prevents elongation. It is frequently tested on ARRT exams.
Position: PA Axial Skull Caldwell The Caldwell projection uses a caudal angle to project petrous ridges into the lower orbits. It evaluates frontal sinuses and orbital margins. Proper positioning prevents distortion. This projection complements Waters and lateral views. It is a core ARRT competency.
Position: PA Skull The PA skull projection demonstrates frontal bones and reduces eye dose. Proper positioning places the forehead and nose against the detector. This projection evaluates fractures and sinus disease. It complements lateral skull views. It is frequently tested on ARRT exams.
