Abstract
A method for imaging an organ with a medical imaging system comprising a radiation source, a detector facing the radiation source, an organ support and a compression paddle, wherein the compression paddle is smaller than the detector, the method comprising offsetting the compression paddle to a position towards a side edge of the detector, moving the radiation source along a trajectory, wherein the trajectory is above the compression paddle and dependent upon the position of the compression paddle, and acquiring images of the organ at several positions along the trajectory.

A method for imaging an object with a medical imaging system comprising an x-ray radiation source, a detector facing the x-ray radiation source, an object support and a compression paddle, wherein the compression paddle is smaller than the detector, the method comprising:
- offsetting the compression paddle to a position towards a side edge of the detector;
- moving the x-ray radiation source along a trajectory dependent upon the position of the compression paddle between a first position aligned with a first side edge of the compression paddle and a second position aligned with a second opposing side edge of the compression paddle;
- and
- acquiring images of the object at several positions along the trajectory.
A medical imaging system comprising:
- an acquisition module comprising:
- an x-ray radiation source;
- an object support;
- a detector configured to capture the radiation from the x-ray radiation source that has passed through the object;
- a compression paddle configured to compress the object against the object support, wherein the compression paddle is smaller than the detector and is offset towards a side edge of the detector;
- and
- a positioning arm configured to position the x-ray radiation source at successive acquisition positions along a trajectory, wherein the trajectory is dependent upon the position of the compression paddle;
- and
- a control unit configured to drive the positioning arm so that the trajectory starts at a position aligned with a first side edge of the compression paddle and finishes at another position aligned with a second opposing side edge of the compression paddle.
A medical imaging system comprising:
- an x-ray radiation source;
- an object support;
- an x-ray detector adjacent the object support;
- a compression paddle configured to compress an object against the object support;
- and
- a positioning arm configured to position the x-ray radiation source at successive acquisition positions along a trajectory, the trajectory dependent upon the position of the compression paddle and defining a first end position aligned with a first side edge of the compression paddle and second end position aligned with a second side edge of the compression paddle, said first and second side edges being opposing outer edges of the compression paddle.
