Abstract

A technique for sealing a portable digital X-ray detector for protection from liquid ingression is disclosed herein. When a detector is assembled, there are leakages due to gaps between two parts. The technique described herein involves application of a hydrophobic coating on areas with the gaps. The hydrophobic coating resists ingression of water and other liquids used in DR detector operation.

HYDROPHOBIC COATING FOR SEALING AN X-RAY DETECTOR

BACKGROUND

 

The present disclosure relates generally to portable digital X-ray detectors and more particularly to a hydrophobic coating for sealing a portable digital X-ray detector.

Generally, during operation X-ray detectors come in contact with liquids such as water and other operating liquids. Digital radiography (DR) detectors have electrical components which are sensitive to the liquids. Therefore, protecting the electrical components from the liquids is necessary, though not an IEC60601-1 mandate.

In conventional DR design, space between external dimensions of the detector and panel glass edges is very limited as ISO4090 definition mandates standard large size detectors. Correspondingly sized large imaging area is required for installing such standard size detectors.

As depicted in Figure 1, to protect the detector from liquid ingression, a conventional technique involves add a sealing gasket along leakage areas. However, adding the sealing gasket requires thick frames, a thin long gasket (for example, about 1.5 meter long gasket for a 14” x17” size detector), and a rugged cover that holds the gasket as compression stresses the cover.

It would be desirable to have an improved technique for sealing a portable digital X-ray detector for protection from liquid ingression.
