0、保持與金屬製外圍器1 1 -14- 200306767 相同電位（接地電位）之第3聚焦柵極電極1 4 0、以及由於熱 電子衝擊而產生X射線之鎢製的標靶（target) 150。第1聚 焦柵極電極1 2 0具有被施加負的電壓時，將熱電子推回至 燈絲側之功能。第2聚焦柵極電極1 3 0具有被施加正的電 壓時，將熱電子拉到標靶之功能。另外，第1聚焦栅極電 極1 2 0與第2聚焦柵極電極1 3 0係連同第3聚焦柵極電極 1 4 0亦具有使電子束聚焦之電場透鏡（聚光鏡）之功能。由陰 極1 1 〇朝向標靶1 5 0之方向依第1聚焦柵極電極1 2 0、第2 聚焦柵極電極1 3 0、第3聚焦柵極電極1 4 0之順序配置， 第1聚焦栅極電極1 2 0、第2聚焦柵極電極1 3 0、以及第3 聚焦柵極電極1 4 0分別在中心部具有使熱電子通過之開口 部1 2 0 a、開口部1 3 0 a、以及開口部1

[Embodiment] Hereinafter, preferred embodiments of the X-ray tube control device and the X-ray tube control method of the present invention will be described in detail with reference to the drawings. (First Embodiment) First, the structure and operation of the X-ray tube 1 managed by the X-ray tube control device 3 of this embodiment will be described. FIG. 1 is a schematic view (cross-sectional view) showing the structure of the X-ray tube 1. As shown in FIG. 1, the X-ray tube 1 is composed of a metal peripheral device 1 held at a ground potential, an electron tube mandrel (Stem) 1 of an insulator, and a beryllium window 1 3 which transmits X-rays. The enclosure is sealed in a vacuum. The X-ray tube 1 includes a cathode 1 1 0 which is heated by a heater to release hot electrons, and a first focusing gate electrode 1 2 0 and a second focusing gate electrode 1 3 which accelerate and focus the hot electrons. 0. The third focusing gate electrode 1 4 0 holding the same potential (ground potential) as the metal peripheral device 1 1 -14- 200306767, and a tungsten target 150 that generates X-rays due to thermionic impact 150 . The first focusing grid electrode 120 has a function to push the hot electrons back to the filament side when a negative voltage is applied. The second focusing gate electrode 130 has a function of drawing hot electrons to the target when a positive voltage is applied. In addition, the first focusing gate electrode 120 and the second focusing gate electrode 130, together with the third focusing gate electrode 140, also function as an electric field lens (condenser) for focusing an electron beam. From the cathode 1 10 to the target 150, the first focusing gate electrode 1 2 0, the second focusing gate electrode 1 3 0, and the third focusing gate electrode 1 4 0 are arranged in this order, and the first focusing The gate electrode 1 2 0, the second focusing gate electrode 1 3 0, and the third focusing gate electrode 1 4 0 each have an opening portion 1 2 0 a and an opening portion 1 3 0 a at the center portion through which thermoelectrons pass. And openings 1 4 0 a. The X-ray tube 1 has a power source 15 including a high voltage generating circuit for applying a positive high voltage to the target 150. The X-ray tube 1 is controlled by an X-ray tube controller 2 connected to the X-ray tube 1 by a control cable 16. As soon as the main power source of the X-ray tube 1 is turned on, the cathode 110 is heated by a heater and releases thermoelectrons. In addition, the X-ray tube 1 starts warming-up to gradually increase the tube voltage to the maximum tube voltage 値, and at the same time, the tube current 値 to the maximum tube current 値 (under the maximum tube voltage 値) Reduce the focal diameter to the minimum tube current 値). At the end of the warm-up period, the first focus grid electrode 12 is applied with a negative cut-off voltage (c u t-0 f f v 11 a g e), and the tube current is stopped. As soon as the X-ray irradiation switch of X-ray tube 1 is turned on, the voltage applied to the first poly 200306767 coke grid electrode 120 rises from the cut-off voltage to the operating voltage. The thermal electrons released by the cathode 1 1 0 are compared with the cathode 11 The second focusing gate electrode 130 having a higher potential of 0 passes through the opening portion 1 2 a of the first focusing gate electrode 120. In addition, the thermionic system passes through the opening portion 1 3 0 a of the second focusing gate electrode 1 3 0 and the third focusing gate electrode 1 4 0 while being accelerated by a tube voltage applied to the target 150. The opening 1440a becomes an electron beam toward the target 150 to which a positive high voltage is applied. When the electron beam passes through the openings 1 2 0 a, the openings 1 3 0 a, and the openings 1 4 0 a, the beam diameter is changed from the focusing gate electrodes 1 to 3, the cathode 1 1 0, and the target 1 5 0 The resulting electric field shrinks. When the electron beam focused by this electric field hits the target 150, the target 150 generates X-rays. X-rays pass through the beryllium window 1 3 and exit the outer surface of the X-ray tube 1. The focus diameter when the electron beam hits the target 1 50 will follow the strength of the electric field lens, the tube voltage, the voltage applied to the first focusing gate electrode 1 2 0, and the second focusing gate electrode 1 3 0 voltage. The voltages applied to the first focusing gate electrode 12 and the second focusing gate electrode 130 are controlled so that the focal diameter 値 is minimized at the maximum tube voltage. In addition, the maximum tube current is determined by the voltage between the first focus gate electrode 12 and the second focus gate electrode 130 which are controlled in this way.

The tube voltage and tube length (pr cess) are determined based on the stop time. For example, when the stop time is 2 months , Pass the state of tube voltage 20 k V and tube current 0 μA for 4 minutes (step 1), tube voltage 40 k V and tube current 20 The state of Α lasts 4 minutes (step 2), the state of tube voltage 62k V and 200306767 tube current 60 μ A lasts 5 minutes (step 3), the state of tube voltage 8 3 k V and tube current 1 100 μA lasts 5 minutes ( Step 4), the state of the tube voltage of 93k V and the tube current of 150 μA lasts for 6 minutes (step 5), the state of the tube voltage of 100 kV and the tube current of 200 μA lasts for 8 minutes (step 6). The tube currents are 100kV and 200 μA. By changing the preheating process in this way, the time required for preheating can be shortened to the necessary minimum of 3 2 minutes. In addition, the voltage of the limiting tube is reduced from 1 50kV is changed to 1 30kV, the limiter current 値 is changed from 360 μ A to 240 μ A, and the focus grid voltage 値 (the voltage applied to the focus grid electrode 値) is changed from V! 3 〇 [V] ( When the tube voltage is 130 kV, the focus diameter is reduced to a minimum grid voltage 値) is changed to V! 〇〇 [V] (When the tube voltage is 100KV, the focus diameter is reduced to a minimum grid voltage値). With these changes, the X-ray tube 1 operates more safely, and the focus diameter can be kept to a minimum. For example, If the maximum tube voltage 値 is to be changed to 105 kV and there is no maximum tube voltage 程式 on the program that is consistent with the changed maximum tube voltage 値, the preheating program is extracted and the maximum tube voltage on the program is drawn.値 is greater than the changed maximum tube voltage 値, and the difference between the programmed maximum tube voltage 値 and the changed maximum tube voltage 成为 becomes the smallest. That is, when the maximum tube voltage 値 is changed to 105 kV, a preheating program (refer to FIG. 7) corresponding to the maximum tube voltage 値 110 kV is extracted and mounted on the X-ray tube controller 2. With this extraction, sufficient warm-up can be ensured. In addition, if there is no maximum tube voltage 程式 on the program that is consistent with the changed maximum tube voltage 値, when the X-ray tube control device 3 has calculated the appropriate -20- 200306767 preheating program, the preheating can be rewritten. Module 2 4 0 b. For example, when the maximum tube voltage 値 is changed to 105 kV, the tube voltage 値 of step 1 can be set to 20 k V, the tube voltage 値 of step 2 can be set to 40 kV, and the tube voltage 步骤 of step 3 can be set to 6 3. 5 k V, set the tube voltage 値 of step 4 to 86.5 kV, set the tube voltage 步骤 of step 5 to 96.5 kV, and set the tube voltage 步骤 of step 6 to 105 kV. For limiter tube voltage 値, limiter tube current 値 and focus grid voltage 値, if there is no maximum tube voltage 程式 on the program that is consistent with the changed maximum tube voltage 値, the limiter tube voltage control module can be extracted. 2 4 0 c, limiting tube current control module 2 4 0 d and focusing grid control module 2 4 0 e, so that the maximum tube voltage 程式 on the program is greater than the maximum tube voltage after the change 且, and the program The difference between the maximum tube voltage 値 and the changed maximum tube voltage 成为 becomes minimum, or after calculating the appropriate 値 limiter tube voltage 値, limiter tube current 栅极, and focus grid voltage 算出, the limiter tube voltage control is rewritten Module 2 4 0 c, limiting tube current control module 2 4 0 d, and focus grid control module 2 4 0 e.
