Solution Overview
Problem
Existing imaging systems require manual repositioning of objects and movement of electromagnetic radiation sources and detectors, leading to inefficiencies and larger footprints, especially in applications like tissue margin verification and electrical device inspection.
Innovation Solution
A cabinet imaging system with a motion control mechanism that moves the object receiving surface relative to the radiation source and detector along non-parallel and non-perpendicular axes, allowing for automatic two and three-dimensional imaging without manual repositioning or movement of radiation components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual repositioning of objects and movement of electromagnetic radiation sources and detectors is used, then imaging can be obtained, but system complexity and footprint increase
Solution Approach 1:
Instead of moving the electromagnetic radiation source and detector to image objects at different positions, the patent inverts the approach by moving the object receiving surface (platform) to bring different objects into the imaging position. This reduces the complexity of moving heavy radiation equipment while achieving the same imaging capability.
Solution Approach 2:
The patent extracts the motion control function from the radiation source and detector system and places it on a separate object receiving surface platform. This separation allows independent optimization of each subsystem, reducing overall system complexity.
2Area of stationary object
If electromagnetic radiation sources and detectors are moved to image different object positions, then complete imaging coverage is achieved, but system footprint increases
Solution Approach 1:
The patent inverts the traditional imaging approach by keeping the radiation source and detector stationary and instead moving the object receiving surface platform to achieve complete imaging coverage. This dramatically reduces the system footprint while maintaining full adaptability to image multiple objects.
Solution Approach 2:
The stationary radiation source and detector are designed to serve multiple imaging positions through the movement of the object receiving surface, making the imaging system universal and adaptable to various object positions without requiring physical relocation of the radiation equipment.
3Productivity
If objects are manually repositioned for imaging, then imaging can be obtained, but time consumption increases
Solution Approach 1:
The system implements self-service automation where the object receiving surface platform automatically positions objects for imaging without requiring manual intervention. The motion control mechanism autonomously moves the platform to the correct positions, significantly reducing time consumption and improving productivity.
Solution Approach 2:
The patent replaces manual mechanical repositioning with an automated motion control system that uses motorized actuators to precisely and quickly position the object receiving surface, eliminating the time-consuming manual operation while maintaining imaging quality.
4Adaptability or versatility
If electromagnetic radiation source and detector are moved within the housing, then imaging flexibility is improved, but device complexity increases
Solution Approach 1:
The patent resolves the contradiction by inverting which component moves: instead of moving the radiation source and detector to achieve imaging flexibility, the object receiving surface platform is moved. This maintains full imaging flexibility while avoiding the complexity of moving heavy radiation equipment within the housing.

AI summary
A method for use in imaging an object in a cabinet. The method comprises receiving an object on an object receiving surface disposed within a cabinet, and determining a position of the object at a first position of the object receiving surface, relative to a source of electromagnetic radiation and a beam axis between the source and an imaging detector. The method comprises operating a motion control apparatus, based on the determined position, to move the object receiving surface within the cabinet along a first axis from the first position to a second position, and operating the motion control apparatus to rotate the object receiving surface about a rotational axis perpendicular to the beam axis. Simultaneously with rotating the object receiving surface, the method comprises triggering the source to emit a cone beam of electromagnetic radiation along the beam axis through the object in its second position towards the detector. The method comprises receiving the cone beam along the beam axis at the detector through the object with the object in the second position, generating a plurality of two-dimensional images of the object, and reconstructing the plurality of two-dimensional images into a three-dimensional data set of the object.
