An X-ray imaging apparatus operates by selecting an appropriate exposure sensitivity corresponding to the X-ray detector to be used. In the apparatus, an exposure sensitivity corresponding to the flat panel detectors used for an X-ray imaging is selected from multiple exposure sensitivities stored in an exposure sensitivity memory unit of the console, and the selected exposure sensitivity is displayed on the display unit of the high-voltage unit. An exposure control is executed based on the exposure sensitivity corresponding to the flat panel detectors used for the X-ray imaging, which is selected from multiple exposure sensitivities stored in an exposure sensitivity memory unit. The exposure control unit of the high-voltage unit suspends the X-ray irradiation from the X-ray tube when an integrated value of the X-ray detected by the X-ray dose sensor reaches to the setting-value set relative to the selected exposure sensitivity.

A timer circuit for an X-ray imaging system having an X-ray generator used to generate images of a patient. The circuit includes a current sensor connected between a main power system and a circuit interrupter, wherein the circuit interrupter is also connected to the X-ray generator. The circuit also includes a timing device coupled between the current sensor and a control computer. The timing device is triggered when a current level detected by the current sensor exceeds an idle current level wherein X-rays are not generated by the X-ray generator. The timing device then measures a time period that the idle current level is exceeded. When the measured time period exceeds a predetermined time period by 10%, the circuit interrupter is activated to turn off current flow to the X-ray generator.

A system including initialization, imaging, alignment, processing, and setting modules. The initialization module obtains patient parameters for a patient and procedure and surgeon parameters. The initialization module selects first settings for an x-ray source based on the patient, procedure, and surgeon parameters. The image module obtains a first sample set of images of a region-of-interest of the patient and a master sample set of images. The first sample set was acquired as a result of the x-ray source operating according to the first settings. The alignment module aligns the first sample set to the master sample set. The processing module processes pixel data corresponding to a result of the alignment based on a pixel parameter or one of the patient parameters. The setting module adjusts the first settings to provide updated settings. X-ray dosage associated with the updated settings is less than x-ray dosage associated with the first settings.

The management system of the X-ray detectors according to the embodiments detects X-rays irradiated from the X-ray generator when X-ray imaging is carried out, and includes an inspection unit and a validity period setting unit. The inspection unit inspects at least one of performance, function, and operation of an actual operation state of the X-ray detector. The validity period setting unit sets a validity period which is a criterion for determining whether the inspection results inspected are valid or not. The system is configured that the X-ray imaging is not performed on a subject when the inspection results are determined to be invalid based on the validity period.

A console for an ex-ray imaging apparatus improves operability and includes in combination an operation panel 26 and a recording button 26b on an imaging system operation lever 26a. In use, the operator grips the imaging system operation lever 26a while video imaging allowing the operator to operate a recording button 26b without unlinking a hand from the imaging system operation lever 26a while watching the display element 25 without changing the line of sight to the operation panel 26. Accordingly, the operator can start recording immediately without changing the line of the own sight, so that the scene for diagnosis is accurately recorded.
