Position: Mandible PA The PA mandible projection demonstrates the mandibular rami and body. It evaluates fractures and alignment. Proper positioning prevents skull superimposition. This projection complements oblique and axial views. It is a standard ARRT competency.
Position: Mandible Axiolateral Oblique The axiolateral oblique mandible projection rotates the head to demonstrate specific regions. It evaluates fractures and TMJ alignment. Proper angulation prevents superimposition. This projection is essential for trauma imaging. It is frequently tested on ARRT exams.
Position: Toes Oblique The oblique toes projection rotates the foot 30 to 45 degrees to separate the phalanges. This view improves visualization of fractures and joint spaces. Proper rotation prevents overlap. It complements AP and lateral views. It is frequently tested on ARRT exams.
Position: TMJ Open Mouth The open mouth TMJ projection demonstrates condylar movement. It evaluates dislocation and joint dysfunction. Proper positioning ensures visualization of the condyle. This projection complements closed mouth views. It is a recognized ARRT special projection.
Position: Toes Lateral The lateral toes projection demonstrates individual digits in profile. It is essential for evaluating fractures and soft tissue injuries. Proper isolation of each toe prevents superimposition. This projection complements AP and oblique views. It is a standard ARRT competency.
Position: TMJ Closed Mouth The closed mouth TMJ projection demonstrates condylar position at rest. It evaluates degenerative changes and alignment. Proper positioning prevents skull base superimposition. This projection is essential for TMJ assessment. It is frequently tested on ARRT exams.
Position: Skull AP Axial Towne The Towne projection demonstrates the occipital bone, foramen magnum, and dorsum sellae. The beam is angled caudally to project facial bones inferiorly. This projection evaluates fractures and cranial pathology. Proper positioning prevents elongation of the skull. It is a core ARRT skull competency.
Position: Sinuses Waters The Waters sinus projection demonstrates maxillary sinuses and orbital floors. It uses an upright position to show air fluid levels. Proper chin elevation is essential. This projection evaluates sinusitis and fractures. It is a core ARRT competency.
Position: Skull Lateral The lateral skull projection demonstrates cranial sutures, parietal bones, and sella turcica. It is essential for evaluating fractures and intracranial pathology. Proper positioning ensures superimposition of cranial structures. This projection is heavily emphasized on ARRT exams. It complements AP axial views.
Position: Sinuses Caldwell The Caldwell sinus projection demonstrates frontal and ethmoid sinuses. It uses a horizontal beam to show air fluid levels. Proper angulation prevents petrous ridge overlap. This projection complements Waters and lateral views. It is frequently tested on ARRT exams.
