Benefits of technology

[0011] The present invention can transmit an unsatisfactorily photographed image or photography information to an X-ray photography management server apparatus in order to manage a photography record including the skill of a radiographer and a photographic error. Accordingly, an X-ray image photographing apparatus that performs digital photography and that achieves improved operation, and a management method are provided.

Problems solved by technology

However, if a deviation from photographic conditions occurs, overexposure or underexposure is likely to occur.
This adversely affects diagnosis.
Thus, unsuccessfully photographed film is not used for diagnosis.
Such failure film is disposed of as unsatisfactorily photographed film.
When a digital X-ray photographing apparatus is used, if a photographed image is not appropriate, outputting the image onto film wastes resources and money.
However, management of unsatisfactorily photographed images is not performed properly, and the number of unsatisfactorily photographed images is unclear.
Thus, unsatisfactorily photographed images can be generated easily.
That is, a subject is likely to be unnecessarily exposed to radiation, and such unnecessary exposure is detrimental to patient's health.

Embodiment Construction

[0031] Various embodiments, features and aspects of the present invention will now be herein described in detail in accordance with the accompanying drawings.

[0032]FIG. 1 is a block circuit diagram showing an exemplary system structure of a medical digital X-ray photographing apparatus according to an embodiment of the present invention. An X-ray photographing apparatus 10 includes an image read controller 12, a random-access memory (RAM) 13, a central processing unit (CPU) 14, a disk interface 15, a local-area network (LAN) interface 16, and a user interface 17 that are connected to each other via an internal bus 11. The RAM 13 includes a RAM unit 13a that stores a control program and a RAM unit 13b that temporarily stores images.

[0033] An output of a flat-panel detector (FPD) 18 that includes a phosphor and a large-screen photoelectric converter, is connected via a data line 10a, to the image read controller 12 that stores images. A hard disk 19 that stores a control program, co...

Abstract

When a retake button is selected, a CPU causes a dialog screen for inputting a reason for a photographic error to be displayed. On the dialog screen, the name of a radiographer who is logging onto an X-ray photographing apparatus and select buttons indicating possible reasons for photographic errors are indicated. The CPU transmits an unsatisfactorily photographed image to a different server.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to an X-ray image photographing apparatus and a management method in which images that are unsuccessfully X-ray photographed are treated as unsatisfactorily photographed images. [0003] 2. Description of the Related Art [0004] Film-screen systems in which intensifying screens and X-ray photographic film are combined together have been widely used for X-ray photography in medical diagnosis. A photography order requested by a doctor is returned to the doctor as X-ray film, and the doctor observes the X-ray film on an X-ray film observation device. In this case, in order to observe a diagnosis region easily, a density range in which observation can be easily achieved, such as a contrast range of about 1.0 D to 1.5 D, is set. However, if a deviation from photographic conditions occurs, overexposure or underexposure is likely to occur. This adversely affects diagnosis. Thus, unsuccessfully ph...
