Abstract
A system and method are disclosed for capturing a radiographic or autoradiographic image of an object, in which a support member is provided to receive the object in an immobilized state; a phosphor screen is provided to transduce ionizing radiation from the source to visible light; film or a digital capture device is provided for capturing an image using the visible light; and the phosphor screen is moved incrementally to facilitate reduction of phosphor screen mottle.
Claims30
A system for capturing a radiographic or autoradiographic image of an object, comprising:
- a support member adapted to receive the object in an immobilized state;
- a phosphor screen adapted to transduce ionizing radiation from the object to visible light;
- means for capturing an image using the visible light;
- and
- a device for moving the phosphor screen incrementally to facilitate reduction of phosphor screen mottle.
A method for capturing a radiographic or autoradiographic image of an object, comprising:
- placing the object in an immobilized state on an object stage;
- capturing a series of images of the object via a phosphor screen adapted to transduce ionizing radiation from the object to visible light;
- and
- moving the phosphor screen incrementally to facilitate reduction of phosphor screen mottle.
A method for capturing multimodal images of an object, comprising:
- placing the object in an immobilized state on an object stage;
- positioning a phosphor screen in an image path from the object to transduce ionizing radiation passing through the object to visible light;
- capturing a series of images of the object using the visible light;
- moving the phosphor screen incrementally to facilitate reduction of phosphor screen mottle in the series;
- removing the phosphor screen from the image path;
- and
- capturing at least one optical image of the object.
A system for capturing multimodal images of an object, comprising:
- a support member adapted to receive the object in an immobilized state;
- a phosphor screen adapted to transduce ionizing radiation from the object to visible light;
- multimodal means for capturing X-ray or optical images of the object, or both;
- a device for incrementally moving the phosphor screen to facilitate reduction of phosphor screen mottle;
- a device for removing the phosphor screen from the image path for capturing optical images;
- and
- means for capturing at least one optical image of the object.
