Tangential patella (Settegast) also know as "Sunrise" Part Position Patient Position CR Collimation What is the degree of flexion of the knee for a tangential Settegast view of the patella?A Settegast is a standard medical x-ray projection that presents a tangential view of the patella. To acquire such an image the patient is placed in a prone position with the knee flexed at least 90 degrees and the field of view centered on the patellofemoral joint space.
What is the degree of angulation for the tangential projection of the patella?What is the degree of angulation for the tangential projection of the patella (Settegast method)? variable—depending on the degree of knee flexion: usually 15-20 if knee is flexed 90.
How far should the knee be flexed for the tangential projection of the patella when done in the prone position?Position of patient Prone position. Position of part Flex the patient's knee about 5-10 degrees. Medially rotate the knee 45-55 degrees from the prone position. Central ray Perpendicular to the IR, exiting the palpated patella.
Where is the CR directed for the tangential projection Settegast method of the patella?The central ray (CR) is directed perpendicular to the imaging receptor (IR) and parallel to the patellarfemo- ral joints. The resulting radiograph clearly delineates both patellae.
