Top board for medical equipment

Overview

The board of the X-ray diagnostic system (bottom in the photo) on which the patient lies is called the "top board." Owing to its features, Toray's carbon composite is adopted by many top boards.

Features

1. Light weight

A carbon composite top board weighs less than one-fifth an acrylic top board and two-fifths a wooden (veneer) top board.

Weight comparison of top boards of 400 mm x 2300 mm x 10 mm in size
Material Weight (kg)
Acrylic top board 11.0
Wooden top board (veneer) 5.0
Carbon composite top board 2.0

2. High strength

A carbon composite top board is at least twice as strong as a wooden top board and at least 1.6 times as strong as an acrylic top board.

Breakdown strength comparison of 2-m top boards receiving an equally distributed load.

Note: The comparison data of breakdown load and deformation amount are relative, with the equivalent aluminum weight of the carbon composite top board representing 100.

3. High X-ray transmissivity

Having a high X-ray transmission rate, carbon composite top board reduces the radiation exposure of the body while achieving high image quality. A carbon composite top board has an X-ray absorption rate of less than one-fifth that of an acrylic top board and less than one-half that of a wooden top board.

Comparison by equivalent aluminum weight (*1)
Material Equivalent AL weight
Acrylic top board 560
Wooden top board 245
Carbon composite top board 100

Note: The comparison data are relative, with the value of the carbon composite top board representing 100.

*1: Equivalent aluminum weight: Indicator of the thickness of aluminum plate in mm through which X-ray transmits. The smaller the value, the easier the transmission of X-ray.
