This paper presents the development of a new technology of registration of ionizing radiation and a new type of detectors - single-cathode multiwire porous detector with neither a gaseous nor semiconductor, but a porous dielectric substance, e.g., CsI, being used as working medium. It is shown that the performance of the multiwire porous detector is stable, ensuring highly efficient detection of both heavily ionizing particles and soft X-rays with a spatial resolution better than $\pm 60μm$. The continuous stable performance opens up new perspectives for using porous detectors in research as well as medicine. The obtained data are basic for the development of the theory of the phenomenon of electrons' drift and multiplication in porous dielectrics under the action of a strong external electric field.

提出了一种具有数字特性的新型X射线成像传感器。它基于彩色光子计数技术。探测器能够单独计数入射的X射线光子，并根据它们的能量将它们分离（每次曝光两个“彩色”图像）。能量选择以射线照相成像速度（GHz全局计数率）实时进行。光子计数、彩色模式和极高的空间分辨率（超过10 l. p./ mm，MTF 50）允许获得图像质量和吸收剂量之间的最佳比率。成像系统的单独块是由薄像素化CdTe晶体（传感器）耦合到大面积VLSI CMOS像素ASIC制成的双面可对接半导体辐射检测器。已建成1、2、4、8个瓦片单元。8块单元具有25 cm x 2.5cm的敏感区域。结果和图像从深入测试的几种配置的系统。X射线成像系统是PIXIRAD成像计数器s.r.l.的技术平台，最近成立的INFN分拆公司。
