The purpose of this application is to provide a tool so that medical technologists can angulate the CR in the 5th lateral space radiograph and perform the procedure without having to incur trial and error, thus reducing patient exposure to a dose of unnecessary radiation. However, from a practical point of view, it is unfeasible for the professional to identify the appropriate correction factor for a given width of the AP pelvis based on the DMRI of the equipment being used.

The algorithm used was developed under an academic investigation and is published under the name of "Quantitative alternative for the determination of the angulation of the Central Ray in X-rays of the lumbar-sacral joint (5th space) lateral". As a product of this publication, a Bilingual application for SmartPhone with Android systems is created, which, by entering parameters of the 3 proposed variables DMRI - AP - DCI, automatically delivers the angulation that must be given to the CR for the 5th space radiography. side.
