1. A tumor tracking block comprising:
a plastic block of a size configured to fit into slotted area spatial dimensions of a dock of a dynamic radiation oncological phantom system;
an inner non-symmetric shaped chamber at a first location within the plastic block;
a non-symmetric shaped target object within the inner non-symmetric shaped chamber, wherein the non-symmetric shaped target object comprises a liquid-formed epoxy volume; and
a plurality of metal fiducial markers within the plastic block and used by a medical linear accelerator (LINAC) to mark tumors in human treatment when the plastic block is positioned in the dock of the dynamic radiation oncological phantom system to track treatment delivery to the non-symmetric shaped target object by the LINAC.
