    • The present invention relates to a light-degradable material for producing disposable medical appliances having main components of polypropylene resin and composite allochromatic agent, wherein the composite allochromatic agent is composed of photoinitiator and sensitizer. The photoinitiator contains ferric citrate (FeC6H5O7) and ferrous pentadione (FeC5H8O2), and the sensitizer contains hexachloroacetone (Cl6C3O) and acetzlbenzene (C8H8O). The material of present invention is neither toxic nor polluted in producing or in using, and can rapidly change color while being irradiated by UV rays. Reuse of these medical appliances can be therebz avoided. When they are thrown awaz in nature, they will keep degrading and decay to powder within 45 &tilde& 75 days. They are desired substitutes of present material for producing disposable medical appliances.
    • 本发明涉及一种用于生产一次性医疗器具的光降解材料,其具有聚丙烯树脂和复合异色剂的主要成分,其中复合异色剂由光引发剂和敏化剂组成。 光引发剂含有柠檬酸铁(FeC6H5O7)和五氢五氧化二铁(FeC5H8O2),敏化剂含有六氯丙酮(Cl6C3O)和乙腈苯(C8H8O)。 本发明的材料在生产或使用中既不毒,也不污染,并且可以在被紫外线照射下快速变色。 这些医疗器具的再利用可以避免。 当他们被抛出来时,他们会在45天和75天之内继续降解和腐烂成粉末。 它们是用于生产一次性医疗器具的现有材料的所需替代物。

    • The invention relates to a method and a system for magnetic induction tomography, the system comprising: at least one transmitting coil (312, 314) for generating a primary magnetic field to be applied to the object of interest (301); and at least one measurement coil arrangement (315, 317) for measuring electric signals induced by a secondary magnetic field which is generated by the object of interest in response to the primary magnetic field, wherein the at least one measurement coil arrangement comprises a plurality of measurement coils which are positioned in substantially the same plane. By using a plurality of independent measurement coils positioned in a plane so as to replace a conventional single measurement coil, the measurement coil across which the measured difference voltage is most sensitive to a change of the secondary magnetic field can be selected for calculating the change of conductivity distribution, resulting in an improved sensitivity of a MIT system.

    • The invention relates to a coil arrangement comprising at least one transmitting coil for generating a primary magnetic field; and a plurality of measurement coils; wherein the at least one transmitting coil (408, 409) and the plurality of measurement coils (410, 411) are arranged in such a way that the flux curve of the primary magnetic field generated by a transmitting coil (409) among said at least one transmitting coil (408, 409) passes into and out of a first measurement coil (410) among said plurality of measurement coils (410, 411), the first measurement coil being the coil closest to the transmitting coil. By enabling the flux of the primary magnetic field to pass into and out of a first measurement coil, the signal induced on the first measurement coil by the positive and negative flux can be compensated, resulting in a reduction of the signal strength of the induced signal on the measurement coil and the signal dynamic range.
