Systems and methods for volume reconstructions using a priori patient data

A system, comprising:

• one or more imaging devices;
• a processor;
• and
• a memory storing data thereon that, when processed by the processor, cause the processor to:
• identify, based on first imaging data generated using the one or more imaging devices, a boundary region corresponding to a shape of an object;
• identify at least one voxel included in second imaging data generated using the one or more imaging devices, wherein the at least one voxel is located outside the boundary region;
• and
• generate a multidimensional image volume corresponding to the object using the second imaging data, wherein generating the multidimensional image volume is with respect to one or more criteria associated with voxels located outside the boundary region, and wherein the one or more criteria comprise a target ratio of attenuation of the voxels located outside the boundary region to attenuation of voxels located inside the boundary region.

A method, comprising:

• identifying, based on first imaging data associated with an object, a boundary region corresponding to a shape of the object;
• identifying at least one voxel included in second imaging data associated with the object, wherein the at least one voxel is located outside the boundary region;
• and
• generating a volumetric construction corresponding to the object using the second imaging data, wherein generating the volumetric construction is with respect to satisfying one or more criteria associated with voxels located outside the boundary region, and wherein the one or more criteria comprise a target ratio of attenuation of the voxels located outside the boundary region to attenuation of voxels located inside the boundary region.
