MULTI-CELLULAR PHANTOM, PHANTOM CONTROL SYSTEM, AND PHANTOM CONTROL METHOD

摘要

A phantom for simulating motions of both the body surface and the internal organs simultaneously, having a structure comprising of a body cell 12 and an internal organ part cell 2. The body cell 12 simulates a body. The internal organ part cell 2 is installed inside a body cell 12 and contains internal organ cells 11a and 11b which simulate internal organs like lung and others. Each of the body cell 12, the internal organ part cell 2 and the internal organ cells 11a and 11b has elastic surface and is able to expand like a balloon. Each cell is provided with a protrusion 170 for connecting a tube 40 to pass fluid.

主权项

1. A multi-cellular phantom for radiation oncology for simulating motions of both a surface of the human body and internal organs simultaneously, comprising:
a body cell to simulate a human body, consisting of a single chamber; one or more internal organ part cells provided in the body cell; and one or more internal organ cells to simulate human internal organs and provided in respective of the internal organ part cells, wherein each of the internal organ part cells and the internal organ cells is provided with a mounting part to connect a tubular member to pass fluid, wherein each of the body cell, the internal organ part cells, and the internal organ cells are constructed with a material with an elastic surface and allowing to expand and contract, wherein when the fluid flows in the cell the expansion occurs, whereas when the fluid flows out from the cell the contraction occurs, and wherein the surface of the body cell moves synchronously with the expansion and contraction motion of the internal organ part cells and the internal organ cells in a manner to propagate the expansion-contraction motion.
