Skull Positioning Critique
This skull positioning video describes the Waters Method or the Parietoacanthial Projection (Setzler, 2010). The video setting is during an x-ray lab for radiology students, the instructor is trying to show the students how to position a patient for an erect Waters Method (Setzler, 2010). As the instructor is explaining the position to the students she is clear on the size and arrangement of the image receptor and where she has placed her marker (Bushong, 2017, p. 182).
As she is talking to her patient she gives direction to place his chin against the center of the bucky (Bushong, 2017, p. 10). This well help position the patient’s mentomeatal…show more content… 419). She did not include that the midsagittal plane is perpendicular to the midline of the table, or bucky (Bontrager & Lampignano, 2014, p. 419). Source to image distance should be 40 inches from the image receptor and a grid should be used (Bontrager & Lampignano, 2014, p. 419). The 10 by 12 image receptor is the correct size needed and shielding is necessary (Bontrager & Lampignano, 2014, p. 419). Central ray should exit the acanthion and it should be perpendicular to the image receptor (Bontrager & Lampignano, 2014, p. 419). Collimation should be collimated in on all four sides, the breathing technique is to suspend (Bontrager & Lampignano, 2014, p. 419). This exam is used to look for fractures, neoplastic, inflammatory processes, or foreign bodies in the eye (Bontrager & Lampignano, 2014, p. 419). The evaluation criteria of the anatomy shown is, infraorbitomeatal line, maxillae, nasal setum, zygomatic bines, zygomatic arches, and anterior nasal spine (Bontrager & Lampignano, 2014, p. 419). Petrous ridges should be before the maxillary sinuses, check for rotation by looking at the distance from the midlateral orbital margin to the lateral cortex of cranium on both sides of the face (Bontrager & Lampignano, 2014, p.
