  FIG. 2 shows an example of the arrangement state of each device in the radiation imaging room 32 of the imaging system 16 according to the present embodiment.

  As shown in FIG. 2, in the radiation imaging room 32, there are a standing table 34 used when performing radiography in a standing position and a prone table 36 used when performing radiation imaging in a lying position. The space in front of the standing table 34 is set as the imaging position of the subject 38 when performing radiography in the standing position, and the upper space of the prone table 36 is used in performing radiography in the prone position.

However, in FIG. 2, the cable is not illustrated. In the imaging system 16 according to the present embodiment, various information is transmitted and received between the electronic cassette 20 and the console 30 by wireless communication.

  The electronic cassette 20 is not used only in the radiographic room or the operating room, but can be used for, for example, a medical examination or a round in a hospital because of its portability.

  Further, in the radiation imaging room 32, the radiation irradiation source 22A is arranged around a horizontal axis in order to enable radiation imaging in a standing position and in a supine position by radiation from a single radiation irradiation source 22A. A support movement mechanism 46 that can be rotated in the direction of arrow A in FIG. 2, can move in the vertical direction (in the direction of arrow B in FIG. 2), and can move in the horizontal direction (the direction of arrow C in FIG. 2). Is provided. The drive source that moves (including rotation) in the directions of arrows A to C in FIG. 2 is built in the support moving mechanism 46, and is not shown here.

  On the other hand, the cradle 28 is formed with an accommodating portion 28 </ b> A capable of accommodating the electronic cassette 20.

  When the electronic cassette 20 is not in use, the built-in storage battery is charged in a state of being housed in the housing portion 28A of the cradle 28. When a radiographic image is taken, the electronic cassette 20 is taken out of the cradle 28 by a radiologist or the like, and the taking posture is established. If it is in the upright position, it is held in the holding part 42 of the standing table 34, and if it is in the upright position, it is held in the holding part 44 of the standing table 36.

  FIG. 3 shows an internal configuration of the electronic cassette 20 according to the present exemplary embodiment.

  As shown in FIG. 3, the electronic cassette 20 includes a housing 112 made of a material that transmits radiation X, and has a waterproof and airtight structure. When the electronic cassette 20 is used in an operating room or the like, there is a risk that blood or other germs may adhere. Therefore, one electronic cassette 20 can be used repeatedly by sterilizing and cleaning the electronic cassette 20 as a waterproof and airtight structure as necessary.

  Inside the housing 112, a grid 116 for removing scattered radiation of the radiation X by the patient from the irradiation surface 114 side of the housing 112 irradiated with the radiation X, and a radiation detector 26 for detecting the radiation X transmitted through the patient. , And a lead plate 118 that absorbs backscattered rays of radiation X are disposed in order. Note that the irradiation surface 114 of the housing 112 may be configured as a grid 116.

  Further, an electronic circuit including a microcomputer and a case 122 that houses a rechargeable storage battery 120 that is detachable are disposed on one end side inside the housing 112. The radiation detector 26 and the electronic circuit are operated by electric power supplied from the storage battery 120 disposed in the case 122. In addition to the detachable storage battery 120, another storage battery may be built in the case 122 so that power can be supplied.

  In the present embodiment, the storage battery 120 accommodated in the electronic cassette 20 can accommodate a plurality of types of characteristics. For example, the storage battery 120 has characteristics suitable for still image shooting and movie recording. Suitable storage batteries are accommodated. As characteristics suitable for still image shooting, since a higher-definition image is required than for moving image shooting, it is preferable to employ a storage battery having higher output type characteristics than moving image shooting. In addition, as a characteristic suitable for moving image shooting, use for a longer time is required than for still image shooting, and therefore a storage battery having a higher capacity type than moving image shooting is preferable. Moreover, as the storage battery 120, storage batteries, such as a lithium ion battery, a nickel cadmium battery, a nickel metal hydride battery, and a capacitor, can be applied. Further, the storage battery 120 may be configured to include a memory for storing a result of photographing by the electronic cassette 20.

  The electronic cassette 20 has a function of detecting the characteristics of the storage battery 120 accommodated therein, and transmits the detection result to the console 30. As a method for detecting the characteristics of the storage battery 120, for example, as shown in FIG. 4, electrodes 124A and 124B and protrusions are provided at different positions in the still image storage battery 120A and the moving image storage battery 120B, and the case 122 side is provided. Electrodes 124A and 124B, detection electrodes 126A and 126B for detecting protrusions, switches, and the like are provided, so that the position of the detection electrodes 124A and 124B of the storage battery 120 and the case shape (for example, protrusions) are different. Thus, the characteristics of the storage battery 120 (whether it is a still image storage battery 120A or a moving image storage battery 120B) may be detected, or the characteristics of the storage battery 120 may be detected by measuring the voltage or current of the storage battery 120. You may make it do. Alternatively, the storage battery 120 may be provided with a wireless tag or IC for storing characteristics, and the electronic cassette 20 may be provided with a receiving means for receiving information from these to detect the characteristics of the storage battery 120.

  Further, the electronic cassette 20 is provided with a lead plate or the like on the irradiation surface 114 side of the case 122 in order to avoid damage to various circuits accommodated in the case 122 due to the radiation X irradiation. It is desirable. In addition, the electronic cassette 20 according to the present exemplary embodiment is a rectangular parallelepiped whose irradiation surface 114 has a rectangular shape, and a case 122 is disposed at one end in the longitudinal direction.

  Further, the size of the storage battery 120 to be stored is set to a size that can be incorporated within the range of the size of the conventional cassette in order to make the size of the electronic cassette 20 common with the size of the conventional cassette. The size of 20 and the conventional cassette are made common (retrofit). As a result, the electronic cassette 20 can be used without requiring any change on the photographing room side.

  The electronic cassette 20 has a radiation detector 26 built therein. The built-in radiation detector 26 is an indirect conversion method in which radiation is converted into light by a scintillator and then converted into charges by a photoelectric conversion element such as a photodiode, and a direct conversion method in which radiation is converted into charges by a semiconductor layer such as amorphous selenium. Any of these may be used. The direct conversion type radiation detector 26 is configured by laminating a photoelectric conversion layer that absorbs radiation X and converts it into charges on a TFT active matrix substrate. The photoelectric conversion layer is made of amorphous a-Se (amorphous selenium) containing, for example, selenium as a main component (for example, a content rate of 50% or more), and when irradiated with radiation X, a charge corresponding to the amount of irradiated radiation. By generating a certain amount of charge (electron-hole pairs) internally, the irradiated radiation X is converted into a charge. The indirect conversion type radiation detector 26 uses a phosphor material and a photoelectric conversion element (photodiode) indirectly instead of the radiation-charge conversion material that directly converts the radiation X such as amorphous selenium into electric charges. It may be converted into an electric charge. As phosphor materials, terbium activated gadolinium oxysulfide (Gd 2 O 2 S: Tb) (abbreviation GOS) and thallium activated cesium iodide (CsI: Tl) are well known. In this case, radiation X-light conversion is performed using a phosphor material, and light-charge conversion is performed using a photodiode of a photoelectric conversion element. The electronic cassette 20 according to the present embodiment will be described as including an indirect conversion radiation detector 26.

  FIG. 5A is a schematic cross-sectional view schematically showing a configuration of four pixel portions of the radiation detector 26 provided in the electronic cassette 20, and FIG. 5B is a diagram of a pixel portion of the radiation detector 26. It is a figure which shows an electrical structure.

  As shown in FIG. 5A, in the radiation detector 26, a signal output unit 52, a sensor unit 54 (TFT substrate 74), and a scintillator 56 are sequentially stacked on an insulating substrate 50 to output a signal. The pixel group of the TFT substrate 74 is configured by the unit 52 and the sensor unit 54. That is, the plurality of pixels are arranged in a matrix on the substrate 50, and the signal output unit 52 and the sensor unit 54 in each pixel are configured to overlap each other. An insulating film 53 is interposed between the signal output unit 52 and the sensor unit 54.

  The scintillator 56 is formed on the sensor unit 54 via a transparent insulating film 58, and forms a phosphor that emits light by converting radiation incident from above (opposite side of the substrate 50) or below into light. It is a thing. Providing such a scintillator 56 absorbs radiation transmitted through the subject and emits light.

  The wavelength range of the light emitted from the scintillator 56 is preferably the visible light range (wavelength 360 nm to 830 nm), and in order to enable monochrome imaging by the radiation detector 26, the wavelength range of green is included. Is more preferable.

  Specifically, the phosphor used in the scintillator 56 preferably contains cesium iodide (CsI) when imaging using X-rays as radiation, and has an emission spectrum of 420 nm to 600 nm at the time of X-ray irradiation. It is particularly preferable to use CsI (Tl) (cesium iodide with thallium added). Note that the emission peak wavelength of CsI (Tl) in the visible light region is 565 nm.

  The sensor unit 54 includes an upper electrode 60, a lower electrode 62, and a photoelectric conversion film 64 disposed between the upper and lower electrodes. The photoelectric conversion film 64 absorbs light emitted from the scintillator 56 and generates electric charges. It is composed of an organic photoelectric conversion material.

Since it is necessary for the upper electrode 60 to cause the light generated by the scintillator 56 to enter the photoelectric conversion film 64, it is preferable that the upper electrode 60 be made of a conductive material that is transparent at least with respect to the emission wavelength of the scintillator 56. It is preferable to use a transparent conductive oxide (TCO) having a high transmittance for visible light and a small resistance value. Although a metal thin film such as Au can be used as the upper electrode 60, the TCO is preferable because it tends to increase the resistance when it is desired to obtain a transmittance of 90% or more. For example, ITO, IZO, AZO, FTO, SnO ₂ , TiO ₂ , ZnO _{2 and the} like can be preferably used, and ITO is most preferable from the viewpoint of process simplicity, low resistance, and transparency. Note that the upper electrode 60 may have a single configuration common to all pixels, or may be divided for each pixel.

  The photoelectric conversion film 64 includes an organic photoelectric conversion material, absorbs light emitted from the scintillator 56, and generates electric charge according to the absorbed light. In this way, the photoelectric conversion film 64 including the organic photoelectric conversion material has a sharp absorption spectrum in the visible region, and electromagnetic waves other than light emitted by the scintillator 56 are hardly absorbed by the photoelectric conversion film 64, and X-rays are obtained. The noise generated by the radiation such as being absorbed by the photoelectric conversion film 64 can be effectively suppressed.

  The organic photoelectric conversion material constituting the photoelectric conversion film 64 is preferably such that its absorption peak wavelength is closer to the emission peak wavelength of the scintillator 56 in order to absorb light emitted by the scintillator 56 most efficiently. Ideally, the absorption peak wavelength of the organic photoelectric conversion material matches the emission peak wavelength of the scintillator 56, but if the difference between the two is small, the light emitted from the scintillator 56 can be sufficiently absorbed. . Specifically, the difference between the absorption peak wavelength of the organic photoelectric conversion material and the emission peak wavelength with respect to the radiation of the scintillator 56 is preferably within 10 nm, and more preferably within 5 nm.

  Examples of the organic photoelectric conversion material that can satisfy such conditions include quinacridone-based organic compounds and phthalocyanine-based organic compounds. For example, since the absorption peak wavelength in the visible region of quinacridone is 560 nm, if quinacridone is used as the organic photoelectric conversion material and CsI (Tl) is used as the material of the scintillator 56, the difference in peak wavelength can be made within 5 nm. Thus, the amount of charge generated in the photoelectric conversion film 64 can be substantially maximized. Note that in this embodiment, the photoelectric conversion film 64 including an organic photoelectric conversion material is described as an example. However, the present invention is not limited thereto, and the photoelectric conversion film 64 may be a material that absorbs light and generates charges. For example, other materials such as amorphous silicon may be applied. When the photoelectric conversion film 64 is composed of amorphous silicon, it can be configured to absorb light emitted from the scintillator over a wide wavelength range.

  The sensor unit 54 constituting each pixel only needs to include at least the lower electrode 62, the photoelectric conversion film 64, and the upper electrode 60. In order to suppress an increase in dark current, the electron blocking film 66 and the hole blocking film are used. It is preferable to provide at least one of 68, and it is more preferable to provide both.

  The electron blocking film 66 can be provided between the lower electrode 62 and the photoelectric conversion film 64. When a bias voltage is applied between the lower electrode 62 and the upper electrode 60, electrons are transferred from the lower electrode 62 to the photoelectric conversion film 64. It is possible to suppress the dark current from increasing due to the injection of. An electron donating organic material can be used for the electron blocking film 66.

  The hole blocking film 68 can be provided between the photoelectric conversion film 64 and the upper electrode 60. When a bias voltage is applied between the lower electrode 62 and the upper electrode 60, the hole blocking film 68 is transferred from the upper electrode 60 to the photoelectric conversion film 64. It is possible to suppress the increase in dark current due to the injection of holes. An electron-accepting organic material can be used for the hole blocking film 68.

  The signal output unit 52 corresponds to the lower electrode 62, a capacitor 70 that accumulates the electric charge transferred to the lower electrode 62, and a field effect thin film transistor (Thin) that converts the electric charge accumulated in the capacitor 70 into an electric signal and outputs it. A film transistor (hereinafter sometimes simply referred to as a thin film transistor) 72 is formed. The region in which the capacitor 70 and the thin film transistor 72 are formed has a portion that overlaps the lower electrode 62 in plan view. With this configuration, the signal output unit 52 and the sensor unit 54 in each pixel are thick. There will be overlap in the vertical direction. In order to minimize the plane area of the radiation detector 26 (pixel), it is desirable that the region where the capacitor 70 and the thin film transistor 72 are formed is completely covered with the lower electrode 62.

  As shown in FIG. 5B, the signal output units 52 in the pixels arranged in a matrix form are extended in a certain direction (row direction), and a plurality of signal output units 52 for turning on and off the thin film transistors 72 of the individual pixels. Gate wiring G and a plurality of data wirings D extending in a direction perpendicular to the gate wiring G and for reading out stored charges from the capacitor 70 through the turned-on thin film transistor 72 are provided. Individual gate lines G are connected to a gate line driver 71, and individual data lines D are connected to a signal processing unit 73. When electric charges are accumulated in the capacitors 70 of the individual pixel units, the thin film transistors 72 of the individual pixel units are sequentially turned on in units of rows by a signal supplied from the gate line driver 71 via the gate wiring G. The electric charge accumulated in the capacitor 70 of the pixel portion in which the thin film transistor 72 is turned on is transmitted through the data wiring D as an analog electric signal and input to the signal processing unit 73. Therefore, the electric charges accumulated in the capacitors 70 of the individual pixel portions are sequentially read out in units of rows.

  Further, the gate line driver 71 sequentially outputs an on signal to each gate line G one line at a time in one image reading operation, and reads out the electric charge accumulated in the capacitor 70 of each pixel unit line by line. In addition to (a so-called progressive scanning method), an ON signal is sequentially output from the gate line driver 71 to each gate wiring G by a plurality of lines (for example, two lines or four lines) in a single image reading operation. It is possible to read out the charge accumulated in the capacitor 70 of each pixel unit (by combining and reading out the charges of the pixels read out simultaneously) by the binning readout method, and the image is sequentially transferred to the readout method and the binning readout method. The reading method can be switched. Specifically, in the present embodiment, shooting is performed sequentially using the readout method in the case of still image shooting, and shooting is performed using the binning reading method in the case of moving image shooting.

  The sequential scanning method and the gate wiring G are divided into odd and even rows for each row, and an ON signal is output to the odd or even gate wiring G for each image reading operation. In addition, the image reading method may be switched between an interlaced scanning method (so-called interlaced scanning method) that reads out charges accumulated in each pixel portion alternately for each line.

  The signal processing unit 73 and the gate line driver 71 are connected to a cassette control unit 69, and the gate control unit 69 controls the gate line driver 71 and the signal processing unit 73.
