  • Patent number: 9833147
    Abstract: A mammography device is disclosed. The mammography device includes a container configured to surround the breast and a plurality of optical fibers attached to be directed inward in the container and configured to perform radiation and detection of light. The container has a base member having an opening, a plurality of annular members continuously disposed to come in communication with the opening, and a bottom member disposed inside the annular member spaced the farthest distance from the base member. The annular members and the bottom member are configured to relatively displace the adjacent annular member on the side of the base member or the base member in a communication direction. Some of the plurality of optical fibers is attached to the plurality of annular members.

  • Publication number: 20110015623
    Abstract: In a cryotherapy apparatus 1, an FPSC2 (free piston type Stirling cooling machine) is used that is driven by a normal power supply, and that is comparatively small and inexpensive. In addition, to a heat absorbing portion 2a of the FPSC2 connected is a base end 6a of an inner pipe 6 in which a refrigerant that operates at a low temperature is encapsulated. As a result of this, when the FPSC2 is driven in a state where a heat exchanging portion 8 provided at a tip 6b of the inner pipe 6 is located on a predetermined site inside a body, heat moves from the heat exchanging portion 8 to the heat absorbing portion 2a of the FPSC2 through the refrigerant. At this time, the refrigerant encapsulated in the inner pipe 6 is insulated from the outside since a vacuumed gap S is formed by the inner pipe 6 being covered with an outer pipe 7. As a result of this, an ice ball is formed on the predetermined site where the heat exchanging portion 8 has been located.
