The articulations of the costal cartilages with the sternum are fibrous, synarthrotic joints. This position demonstrates an AP projection of the posterior ribs above the diaphragm, about 1-10. Place cassette lengthwise in Bucky tray, centered transversely at the level of T7. If patient's condition allows, have patient place hands under head and flex elbows upward to decrease angle of ribs. CR is perpendicular directed to the level of T7.
Respiration is suspended at the end of full inhalation to depress the diaphragm.
This projection of the ribs below the diaphragm demonstrates an AP projection of the posterior ribs below the diaphragm, approximately 10-12. You may use a 14 x17 either lengthwise or crosswise in the Bucky. Patient placed in true AP position, recumbent if condition allows. Hands resting under head with elbows relaxed against table. CR is perpendicular directed to the midpoint of the film.
