Body Positions Flashcards
Lateral- position
Animal is in lateral recumbency.
X-ray beam is centered on heart or caudal edge of scapula.
Thoracic limbs are pulled cranially (avoid overstretching).
Foam wedge under sternum to correct rotation.
Collimation includes entire bony thorax.
Exposure is made at peak inspiration.
Lateral- rad
Animal is in lateral recumbency.
X-ray beam is centered on heart or caudal edge of scapula.
Thoracic limbs are pulled cranially (avoid overstretching).
Foam wedge under sternum to correct rotation.
Collimation includes entire bony thorax.
Exposure is made at peak inspiration.
Dorsoventral (DV) -position
Animal is in sternal recumbency.
X-ray beam is centered on heart or caudal edge of scapula (be careful not to center too far caudally).
Spine and sternum are superimposed.
Limbs are in ‘crouching position’.
Head is straight.
Collimation includes entire bony thorax.
Exposure is made at peak inspiration

Ventrodorsal (VD)- image
Animal is in dorsal recumbency.
X-ray beam is centered on heart or caudal edge of scapula.
Spine and sternum are superimposed.
Thoracic limbs are pulled cranially (avoid overstretching).
Collimation includes entire bony thorax.
Exposure is made at peak inspiration.
Ventrodorsal with thoracic limbs pulled caudally- position
Animal is in dorsal recumbency.
X-ray beam is centered on heart or caudal edge of scapula.
Spine and sternum are superimposed.
Thoracic limbs are pulled caudally alongside the body.
Exposure is made at peak inspiration.
Eliminates superimposition of scapulae over cranial thorax and give more clear view of the mediastinum.
Ventrodorsal with thoracic limbs pulled caudally- image
Animal is in dorsal recumbency.
X-ray beam is centered on heart or caudal edge of scapula.
Spine and sternum are superimposed.
Thoracic limbs are pulled caudally alongside the body.
Exposure is made at peak inspiration.
Eliminates superimposition of scapulae over cranial thorax and give more clear view of the mediastinum.
Ventrodorsal Oblique- position
Animal is in dorsal recumbency.
Sternum is rotated away from area of interest (heart follows sternum).
X-ray beam is centered on area of interest.
Thoracic limbs are pulled cranially (avoid overstretching).
Exposure is made at peak inspiration.
Reduces superimposition of spine/sternum and mediastinum.
Ventrodorsal Oblique- image
Animal is in dorsal recumbency.
Sternum is rotated away from area of interest (heart follows sternum).
X-ray beam is centered on area of interest.
Thoracic limbs are pulled cranially (avoid overstretching).
Exposure is made at peak inspiration.
Reduces superimposition of spine/sternum and mediastinum.
Ventrodorsal Tangential- position
Animal is in dorsal recumbency.
Thoracic limb(s) is extended.
Sternum is rotated away from side of interest for evaluation of more dorsal area or toward side if interest if interested in extreme ventral area.
X-ray beam is centered on lesion.
Collimation includes lesion and some adjacent normal tissues.
