An anthropomorphic phantom for medical imaging systems is disclosed, which is configured with organ models designed to mimic the three-dimensional shape of human organs, and also by the arrangement of plate-like first connecting elements inside their corresponding organ models, lesion phantoms for simulating tumors can be fixedly secured inside the corresponding organ model using a plurality of first connection holes formed on the first connecting element. Therefore, by the distribution of those first connection holes, not only the lesion phantoms can be arranged at any position inside the corresponding organ model at will as required, but also by modularized design of the anthropomorphic phantom, organ models can first be assembled to form a module structure while the whole module structure with the organ model can be moved into and assembled easily with a torso-like humanoid housing of the anthropomorphic phantom by the use of a handle element.

Anthropomorphic phantom for medical imaging systems

A lesion phantom is disclosed, which is a spherical ball having a cavity formed therein for housing contrast agents or medicines, and is enabled for the quantitative evaluation of a medical image in drug development and evaluation. In an embodiment, the cavity of the lesion phantom is coupled to a tapering ring and is configured to be sealed by a silicon plug, in order to ensure that contrast agents or medicines can be fed into the cavity easily and conveniently without causing any problem, such as overflowing, a bubble residue problem, radioactive contamination, etc. Moreover, by the arrangement of a retractable fixing bar, the positioning of the lesion phantom can be adjusted flexibly at will, and additionally by the tapering of the tapering ring, the lesion phantom can be prevented from being damaged by any extreme, sudden, unjust, or improper force exerted, and thus the lifespan of the lesion phantom can be prolonged.
