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.
