[0016] figure 1 is a block diagram showing the configuration of the information processing apparatus used in the X-ray radiographing system according to the present embodiment. The information processing apparatus is constituted by a PC (Personal Computer) capable of being driven by an AC (alternating current) power supply and a battery, such as a tablet PC.

[0017] The examination information acquisition unit 101 acquires examination information scheduled for an examination to be performed by the X-ray detector 200 constituting the X-ray radiography system such as an FPD (Flat Panel Detector) from an external examination instruction device through, for example, a wireless communication function, as digital data. The examination information is, for example, information for managing scheduled examinations such as chest radiography and abdominal radiography for each patient. The examination information presence / absence determination unit 102 detects whether the examination in...

[0028] Next, a second embodiment will be described. Since the structure of the information processing apparatus used in the X-ray radiography system in this embodiment is similar to that of the first embodiment, its description is omitted here.

[0029] image 3 Processing operations of the information processing device according to the second embodiment are shown. Step S301 to step S311 respectively with figure 2 Steps S201 to S211 in are the same. The difference between the second embodiment and the first embodiment is only that: if it is determined in step S308 that there is no checking information, the device is not switched to the sleep state but directly switched to sleep (step S312 ). In other words, in figure 2 In the flow chart of , the predetermined time M is set to 0 (M=0).

Abstract

The invention relates to an information processing apparatus and a control method thereof. When a predetermined time elapses after the start of a screen saver, it is detected whether or not an apparatus is driven by a battery. For AC driving, the apparatus is shifted to a sleep state for power saving, since there is a low power-off risk. For battery driving, it is discriminated whether or not the battery has a sufficient remaining battery level, and the apparatus is shifted to a rest state for avoiding the power-off risk, when the battery has a low remaining battery level. When the remaining battery level is sufficient, the apparatus is shifted to the sleep state and then to the rest state after a first predetermined time, if inspection information is absent, whereas the apparatus is shifted to the sleep state and then to the rest state after a second, longer predetermined time, if the inspection information is present.

Description

technical field [0001] The present invention relates to an information processing device used in an X-ray radiography system and capable of being driven by a battery, and a control method and program for such an information processing device. Background technique [0002] In the related art, there has been an increased need to realize efficient and high-speed examinations by converting patient medical image information generated at hospitals into digital data and by storing and transmitting the digital data. Therefore, until now, even in the field of X-ray imaging, a digital system for outputting digital data by using an X-ray detector such as an FPD (Flat Panel Detector, Flat Panel Detector) has been widely used in place of a screen / film system. The number of cases where a wireless communication function is provided for an X-ray detector is also increasing. [0003] An all-wireless system has been established in which wireless communication is performed by using a PC (Per...
