摘要： Provided is a phantom device having an internal organ simulating phantom. The phantom device comprises: a phantom receiving radiation emitted from a radiation emitting unit and comprising therein a simulant that simulates an internal organ; a lifting unit installed under the phantom to support the phantom and moving the phantom relative to the radiation emitting unit, the lifting unit comprising: a worm shaft axially rotated by an external torque and having a worm formed on an outer circumferential surface thereof, a cylindrical worm wheel having gear grooves formed on an outer circumferential surface thereof to engage with the worm and a female screw formed on an inner circumferential surface thereof, and rotated by the axial rotation of the worm shaft; and a driven screw engaging with the female screw of the worm wheel, and moved up and down by the rotation of the worm wheel to move up and down the phantom; and a horizontal moving unit interlocking with the lifting unit and horizontally moving the phantom. Accordingly, since the phantom device can simulate any movement pattern, even the respiratory movement pattern of a patient's internal organ to accurately determine a desired dose of radiation to be delivered to the body part, high quality assurance of radiation therapy equipment can be achieved and therapeutic effect can be improved.

摘要： Provided is a phantom for evaluating the accuracy of image registration software based on a result of matching tomograms of a predetermined position of the phantom, taken using two or more imaging apparatuses. Accordingly, it is possible to more efficiently evaluate the accuracy of the image registration software by comparing the tomograms with one another using a three-dimensional analysis. In addition, it is possible to facilitate the comparison of the tomograms with one another by installing a plurality of indicating bars in the phantom so that their cross sections can appear on each of the tomograms.
