[0033] (general description of the device)
[0034] figure 1 is a block diagram of a subject information acquisition device according to the present invention.
[0035] The patient takes a prone position on the subject contacting part 1 , and the patient's breast hangs down from the breast insertion opening 13 which is an opening in the subject contacting part 1 , and comes into contact with the holding part 11 . The subject contact member 1 is a member having strength to support a patient. When the respective constituent elements of the subject information acquiring device according to the present invention are housed in the frame, the subject contact member 1 can be formed by providing an opening in the upper surface of the frame.
[0036] As described in detail below, the measurement unit 3 irradiates the breast held by the holding member 11 with light energy from the light source 5 . In doing so, photoacoustic waves are generated from the surface of the breast and / or li...

[0075] In the liquid circulator according to the first embodiment, the UV irradiator 84 , the degassing device 85 and the heating device 86 are arranged between the tank 82 and the bowl receiver 30 . In the second embodiment, as Figure 5 As shown, the functions of UV irradiator 84 , degassing device 85 and heating device 86 are provided in tank 82 .
[0076] A heating device 86 is built into the tank 82, and the temperature of the acoustic matching liquid 35 is controlled to be around body temperature. And, since the UV irradiator 84 is also installed in the tank 82 , a sterilizing effect is also obtained in the acoustic matching liquid 35 in the tank 82 . If the inner wall of the tank 82 is surface-treated so as to reflect UV light, the germicidal effect is increased by the reflection of UV light. The degassing device 85 may be built into the tank 82 , or an external degassing device may be connected to the tank 82 and perform degassing while circulating the liquid between...

[0081] In the first embodiment, the configuration in which the UV irradiator 84 is provided in the flow path is described, while in the second embodiment, the configuration in which the UV irradiator 84 is provided in the tank 82 is described. In the third embodiment, such as Figure 6 As shown, the UV irradiator 84 is disposed above the holding member 11 . In these cases, ultraviolet light is emitted onto the acoustic matching liquid 35 via the holding member.
[0082] The UV irradiator 84 may be provided directly on top of the holding member 11 .
[0083] and, if Figure 6 As shown, a cover-like member such as an opening cover 844 capable of closing the breast insertion opening 13 may also be provided. By attaching the UV lamp 841 to the opening cover 844, damage to the surface of the holding member 11 is prevented. Also, it is desirable if the opening cover 844 has light-shielding properties because emitted ultraviolet light does not leak out of the device, which makes ...
