    摘要： To provide patient shielding of non-treatment areas bordering a treatment zone of the patient during radiation therapy, a shield device may be located on the patient. The shield device has a plurality of interconnected and overlapping elements, e.g. in a scale maille arrangement, that forms a conformal sheet that can be laid over the shielded portion of the patient, e.g. over the contralateral breast during breast cancer treatment. The edge of the scale maille sheet is substantially configurable and can be made to conform to the field edge of the treatment zone on the patient.

    摘要： Provided is a device for measuring a micro flow rate. The device includes a container having an internal space for containing a fluid flowing therein and an inflow line and an outflow line formed in communication with the internal space, a fluid level gauge configured to sense whether a level of a fluid collected in the container rises to a predetermined height to conduct or block flow of an electric current, a control valve disposed in the outflow line and configured to open or close the outflow line according to a state in which the control valve is electrically connected to or disconnected from the fluid level gauge such that the outflow line is opened or closed according to a change in the fluid level; and a control unit configured to calculate a micro flow rate of the fluid collected in the container using information acquired from at least one of the fluid level gauge and the control valve.

    摘要： A radiation imaging apparatus includes a radiation detection panel configured to detect radiation irradiated by a radiation generation unit, a first member and second member arranged on the incident direction side of the radiation, and a third member and fourth member arranged on a side opposite to the incident direction of the radiation. The second member is arranged between the first member and the radiation detection panel, and the third member is arranged between the radiation detection panel and the fourth member. The second member and the third member are lower in elastic modulus than the first member and the fourth member, and the elastic modulus of the second member is equal to or lower than that of the third member.

    摘要： Embodiments of the present disclosure are directed to sealant compositions including a base composition with at least one sulfur-containing polymer, a curing agent composition, and an electrically conductive filler including carbon nanotubes and stainless steel fibers. The electrically conductive filler can be in either or both of the base composition and the curing agent composition. The sealant compositions are substantially Ni-free and exhibit unexpectedly superior EMI/RFI shielding effectiveness.

    摘要： Radiation shields and radiation shielding systems for attenuating ionizing radiation include two or more attenuating elements, such as layers. The two or more attenuating elements may include different attenuating materials. The two or more attenuating elements may be configured to attenuate ionizing radiation differently than one another. In some embodiments, different attenuating elements may be configured for use with different energies or ranges of energies of ionizing radiation. The concurrent use of two or more layers or other attenuating elements may optimize the ability of a radiation shield to attenuating ionizing radiation. Systems and methods for attenuating ionizing radiation are also disclosed.
