Radiation image pick-up device and method therefor, and radiation image pick-up system

A sensor substrate for use in a radiation image pick-up device having a scanning circuit, comprising:

• a pixel including a conversion element for converting incident radiation into an electric charge and first and second semiconductor elements for transferring a signal charge corresponding to the electric charge converted by the conversion element for storage or further processing;
• and
• a scanning circuit for independently selecting the first and second semiconductor element.

A radiation image pick up device comprising:

• a pixel including a conversion element for converting incident radiation into an electric charge and first and second semiconductor elements, said first semiconductor element for transferring a signal charge corresponding to the electric charge converted by the conversion element for storage or further processing without use of said second semiconductor element, and said second semiconductor element for transferring a signal charge corresponding to the electric charge converted by the conversion element for storage or further processing without use of said first semiconductor element;
• and
• a scanning circuit for independently selecting the first and second semiconductor element.
