Apparatus for tomosynthesis image reconstruction

An apparatus for tomosynthesis image reconstruction, comprising:

• a digital storage memory configured to store processor executable instructions;
• and
• one or more processors configured to execute the processor executable instructions to:
• receive a first projection image data set and a second projection image data set which is acquired after the first projection image data set, wherein the first projection image data set comprises first projection data, and the second projection image data set comprises second projection data, wherein the first projection image data set and the second projection image set are useable for reconstructing a tomosynthesis image of at least a region of interest of a body part;
• select a first subset of the first projection data based on the second projection data comprising at least one high contrast object;
• and
• reconstruct an enhanced image of at least the region of interest of the body part based on the first subset of the first projection data and at least a second subset of the second projection data, and wherein a part of a biopsy equipment is inserted into the body part between acquisition of the first projection image data and the second projection image data, such that the second projection image data comprises the part of the biopsy equipment.

A method for tomosynthesis image reconstruction, comprising:

• providing a first projection image data set and a second projection image data set which is acquired after the first projection image data set, wherein the first projection image data set comprises first projection data, and the second projection image data set comprises second projection data, wherein the first projection image data set and the second projection image set are useable for reconstructing a tomosynthesis image of at least a region of interest of a body part;
• selecting a first subset of the first projection data based on the second projection data comprising at least one high contrast object;
• and
• reconstructing an enhanced image of at least the region of interest of the body part based on the first subset of the first projection data and at least a second subset of the second projection data, wherein a part of a biopsy equipment is inserted into the body part between acquisition of the first projection image data and the second projection image data, such that the second projection image data comprises the part of the biopsy equipment.

A non-transitory computer-readable medium having one or more executable instructions stored thereon which, when executed by at least one processor, cause the at least one processor to perform a method for tomosynthesis image reconstruction, the method comprising:

• providing a first projection image data set and a second projection image data set which is acquired after the first projection image data set, wherein the first projection image data set comprises first projection data, and the second projection image data set comprises second projection data, wherein the first projection image data set and the second projection image set are useable for reconstructing a tomosynthesis image of at least a region of interest of a body part;
• selecting a first subset of the first projection data based on the second projection data comprising at least one high contrast object;
• and
• reconstructing an enhanced image of at least the region of interest of the body part based on the first subset of the first projection data and at least a second subset of the second projection data, wherein a part of a biopsy equipment is inserted into the body part between acquisition of the first projection image data and the second projection image data, such that the second projection image data comprises the part of the biopsy equipment.
