Forums Deep Inspiration Breath Hold Vertical shifts from radiographic images Reply To: Vertical shifts from radiographic images


Good question! We double check ourselves to ensure patient is taking correct breath by checking 1) heart contour on tangential film- this film in general could help confirm consistency in patient’s breath since it is obtained after shifts and newly captured reference fields 2) difference in FB AP ssd and BH AP ssd and see how they compare to the planned  3) match to spine on lateral and if sternum is off, often times they need to take more or less of a breath to correct it
