Optional chair specifications
Chair with a backrest not too high
Chair with an Anti-saddle-rotation function
Chair with a footrest
If a pediatric patient is an X-ray exposed while using a
chair with a backrest if the shoulder line of the child is
lower than the height of the backrest, use a child cushion
to increase the sitting height of the pediatric patient (to
prevent bump with the chair backrest and the equipment
rotator part).
For patients with reduced mobility or patients ((the elderly
or children) who have difficulty fixing their body for a long
time, if a chair with a 'backrest' is used, image quality
degradation may occur due to the patient leaning on
his/her back. Before using a chair with a backrest, it is
required to check the appendix section.
