Position: Trauma Cross Table Ankle The cross table ankle projection demonstrates the ankle mortise in trauma patients. A horizontal beam prevents movement of injured limbs. Proper positioning ensures accurate joint visualization. This projection is essential for fracture assessment. It is a standard ARRT competency.
Position: Trauma Cross Table Foot The cross table foot projection evaluates fractures without moving the foot. It is essential for severe trauma or postoperative patients. Proper alignment prevents distortion. This projection complements AP and oblique views. It is recognized on ARRT exams.
Position: Trauma Cross Table Shoulder The cross table shoulder projection demonstrates the humeral head and glenoid relationship. It is essential for trauma patients who cannot abduct the arm. Proper beam alignment is critical. This projection evaluates dislocations and fractures. It is a core ARRT trauma competency.
Position: Trauma Lawrence Shoulder The Lawrence method is an inferosuperior axial projection used for trauma. The arm is abducted as tolerated while the beam passes from inferior to superior. This projection evaluates dislocations and joint alignment. Proper positioning prevents distortion. It is frequently tested on ARRT exams.
Position: Trauma Velpeau Shoulder The Velpeau projection is used when the patient cannot abduct the arm. The patient leans backward while the beam is angled inferiorly. This projection demonstrates the humeral head and glenoid. It is essential for trauma imaging. It is a recognized ARRT special projection.
Position: Trauma Cross Table Femur The cross table femur projection demonstrates the femur without moving the patient. It is essential for trauma evaluation. Proper alignment ensures visualization of the entire shaft. This projection complements AP views. It is a standard ARRT competency.
Position: Sinuses Lateral The lateral sinus projection demonstrates all sinus groups in profile. It is essential for evaluating air fluid levels. Proper positioning prevents rotation. This projection is foundational for sinus imaging. It is a standard ARRT requirement.
Position: Trauma Cross Table Elbow The cross table elbow projection evaluates fractures when the patient cannot flex the arm. A horizontal beam demonstrates joint alignment. Proper positioning prevents superimposition. This projection is essential for trauma imaging. It is frequently tested on ARRT exams.
Position: Sinuses SMV The SMV sinus projection demonstrates sphenoid and ethmoid sinuses. It requires hyperextension of the neck. This projection evaluates sinusitis and fractures. Proper positioning is challenging but essential. It is a recognized ARRT special projection.
Position: Trauma Partial Flexion Elbow AP The partial flexion elbow projections are used when the patient cannot fully extend the arm. Two exposures evaluate the distal humerus and proximal forearm separately. This method ensures diagnostic visualization despite limited mobility. It is essential for trauma imaging. It is a recognized ARRT technique.
