Abstract

The present disclosure relates to the field of a cabinet x-ray incorporating an x-ray tube, an x-ray detector, and an optical camera for the production of organic and non-organic images. The computing device receives data including video data from an optical camera, a laser detector, an infrared detector, an ultrasonic detector, or a weight scale or pressure sensor, and determines automatically, based on the resultant data, if a sample/specimen has been left in the sample chamber. In particular, the disclosure relates to a system and method with corresponding apparatus for automatic detection if a sample/specimen has been left in the sample chamber without having to open the chamber door.

Dependent claims

A cabinet X-ray system for obtaining X-ray images of a specimen, the system comprising:

a cabinet defining an interior chamber;
a display;
an X-ray system including:
an X-ray source;
an X-ray detector;
a specimen platform;
at least one sample detector to determine the presence or absence of the specimen disposed on the specimen platform;
and
a controller configured to:
receive a first set of data from the at least one sample detector before the specimen is disposed on the specimen platform;
selectively energize the X-ray source to emit X-rays through the specimen disposed on the specimen platform to the X-ray detector;
control the X-ray detector to collect a projection X-ray image of the specimen when the X-ray source is energized;
selectively display the X-ray image on the display;
receive a second set of data from the at least one sample detector after the X-ray detector has collected a projection X-ray image of the specimen;
and
compare the first set of data from the at least one sample detector to the second set of data from the at least one sample detector to determine if the specimen is disposed on the specimen platform.

A cabinet X-ray system for obtaining X-ray images, projection X-ray images and reconstructed tomosynthetic X-ray images of a specimen, the system comprising:

a cabinet defining an interior chamber and an equipment enclosure;
a display;
an X-ray system including:
an X-ray source positioned in the interior chamber;
an X-ray detector positioned in the interior chamber;
a specimen platform positioned in the interior chamber and which is a protective cover of and in physical contact with the X-ray detector;
and
a motion control mechanism positioned in the interior chamber and configured for moving the X-ray source to or along a plurality of positions within the interior chamber relative to the specimen disposed on the specimen platform;
at least one sample detector positioned in the interior chamber configured to determine the presence or absence of the specimen disposed on the specimen platform;
and
a controller positioned in the equipment enclosure and configured to:
receive a first set of data from the at least one sample detector before the specimen is disposed on the specimen platform;
selectively energize the X-ray source to emit X-rays through the specimen to the X-ray detector at selected positions of the X-ray source relative to the specimen such that the isocenter of the emitted X-rays at the selected positions is located at a surface of the X-ray detector;
control the X-ray detector to collect projection X-ray images of the specimen when the X-ray source is energized at the selected positions, wherein one of the projection X-ray images is a two-dimensional X-ray image taken at standard imaging angle of approximately 0°;
create a tomosynthetic X-ray image reconstructed from a collection of projection X-ray images;
process the collection of the projection X-ray images in the controller into one or more reconstructed tomosynthetic X-ray images representing a volume of the specimen and relating to one or more image planes that are selectively the same or different from that of the two-dimensional X-ray image;
selectively display at least one of the two-dimensional X-ray image, the one or more reconstructed tomosynthetic X-ray images and the optical image on the display;
receive a second set of data from the at least one sample detector after the X-ray detector has collected the projection X-ray images of the specimen;
and
compare the first set of data from the sample detector to the second set of data from the sample detector to determine if the specimen is disposed on the specimen platform.
