ROTATION TYPE DUAL WINDOW PHANTOM |
摘要 |
PURPOSE: A rotary type dual window phantom is provided to minimize errors as measurement is performed while an ionization chamber is fixed to the phantom. CONSTITUTION: A rotary type dual window phantom includes a box-shaped phantom (10) in which fluid is filled inside, an ionization chamber (20), a first phantom window (11), and a second phantom window (12). The ionization chamber is installed so that a radiation measuring sensor (21) is arranged inside the phantom. The first phantom window is formed on a side of the phantom so that radiation radiated from radiation radiator is transmitted through the inside of phantom. The second phantom window is formed on a side of the phantom facing the first phantom window so that radiation radiated from radiation radiator is transmitted through the inside of phantom.
