摘要： An array substrate for use in an X-ray sensing device includes a silicon insulator on a thin film transistor. The silicon insulator is silicon nitride or silicon oxide that has a strong adhesive strength to the active layer of the thin film transistor. Thereafter, an organic material, as a planarizing layer, is formed on the silicon insulator, so that the leakage current, which has a bad influence on the operation of the thin film transistor, can be prevented.

The solid radiation detector is formed by a conversion layer which converts radiations bearing thereon image information to electric charges, and a two-dimensional image reader which detects the electric charges obtained by the conversion and is formed by a two-dimensional array of a plurality of solid radiation detecting elements. A high frequency component attenuation phosphor layer attenuates high frequency components of the electric charges bearing thereon high frequency components of the image information not lower than a Nyquist frequency, which is defined by the pitches of the array of the solid radiation detecting elements, so that aliasing noise due to the high frequency components of the image information not lower than the Nyquist frequency becomes not stronger than 30% of intrinsic noise power at a frequency equal to a half of the Nyquist frequency.

摘要： What are formed on an insulating substrate are gate electrodes and data electrodes provided in a grid pattern, a TFT provided in each grid and connected to the gate electrode and the data electrode, an interlayer insulating film formed on the TFT and including a contact hole penetrating the film itself, and a sense electrode provided on the interlayer insulating film and passing through the contact hole. On the interlayer insulating film, an upper layer insulating film is formed so as to cover the sense electrode. A surface of the interlayer insulating film in which surface the sense electrode is formed is flat. On this account, it is possible to provide an uneven pattern sensing device capable of smoothing out a surface thereof without any increase of the manufacturing process and limitation of a choice of materials for a protective film.

摘要： A small-size gamma camera is capable of reliably and quickly detecting the accumulated position of a radiation source in an examinee. When the examinee is scanned with the gamma camera which has an area sensor comprising 256 (16null16) semiconductor detecting elements, display elements of a display unit on a rear panel of the gamma camera are turned on to display a pattern indicative of the accumulated position of the radiation source. According to the displayed pattern on the display elements, the operator of the gamma camera moves the gamma camera to detect the accumulated position of the radiation source reliably within a short period of time.

摘要： In a method for producing a detector array for detection of X-ray radiation, a stack is formed from a sequence of layers which are arranged one above the other in a stacking direction and are connected to one another. This results in a layer group, comprising at least one sensor layer composed of a material which is sensitive to that radiation and a separating layer, repeatedly. The stack is then broken down into slabs such that a row sequence in one slab reproduces the layer sequence in the stack. The slab is made contact with, optically or electrically, on at least one of its surface faces. The rows which are formed from the sensor layers in the slab are preferably subdivided by the introduction of separating spaces into individual sensor elements or pixels. A reflector material can be poured into the separating spaces. The method allows the production of relatively large quantities of one-dimensional or multidimensional detector arrays in a simple manner.
