After you have determined the correct vertical angulation for the area to be radiographed, adjust the tube head using the angle dial on the tube head as a reference. structures. A patient may have an unusually high maxillary vault or an unusually deep palatal vault. In either case, you would decrease the standard vertical angulation by about 5°. On the other hand, for a patient with an unusually shallow vault, you would increase the angulation by about 5°. The more experienced you become in X-ray techniques, the easier it will be for 1-19
