• Third marker: thoracolumbar junction Additional oblique projections are acquired

• Fourth marker: mid lumbar spine (L3). (‘facet’) joints:

Marker placement is helped by either palpating • Right 20º ventral-left dorsal oblique (R20V-
cranially from the lumbosacral junction which LDO) and Left 20º ventral-right dorsal oblique
can be felt as a dip or from the last (18 ) rib. (L20V-RDO).
