A CPU (57) functions as a receiving unit (65) and as an association processing unit (66). The receiving unit (65) receives an imaging order (20), patient information (21), a radiographic image (31) and imaging conditions (36). The association processing unit (66) generates a radiographic image file (40) on the basis of information received by the receiving unit (65). The association processing unit (66) assigns the same order ID (43) to the radiographic image file (40) between when a new imaging order (20) is received from the receiving unit (65) and when the radiographic image (31) is determined to be a diagnostic image (31S). In this manner, a diagnostic image file (40S) and a failed image file (40F) generated when an imaging failure occurs are associated with one another using an order ID (43).

Description

Image information management apparatus, image information management method, and image information management program

The present invention relates to a failure information management apparatus, a failure information management method, and a failure information management program.

In medical practice, for example, radiographic imaging using a radiography system and MRI images using a nuclear magnetic resonance (MRI) imaging system are widely used for taking medical images using various modalities. It has been broken. When such a medical image is taken, a photographing condition such as a doctor or a radiographer is set on the modality console. For example, in the case of radiographic imaging using a radiographic system, tube voltage, tube current, and radiation irradiation time applied to a radiation source that irradiates radiation toward a subject (patient) are set as imaging conditions.

When photographing medical images, there are cases where photographing fails due to a mistake in setting photographing conditions by the photographer (referred to as image loss). The medical image photographed at this time (referred to as a “failed image”) is determined to be an image unsuitable for diagnosis by the examiner in the post-photographing process. However, in order for the photographer to learn how to improve the setting of the shooting conditions, the shot image and the shooting condition when shooting the shot image (referred to as the shot shooting condition) are useful information. Therefore, in the failure information management apparatus described in Japanese Patent Application Laid-Open No. 2009-268586, a failure image and a failure shooting condition are stored in association with each other. As described above, if the failed image and the failed photographing condition are stored in association with each other, the photographer can easily search and refer to them.

Since a failed image is unsuitable for diagnosis, if a failure occurs due to a mistake in setting the shooting conditions, the photographer resets the shooting conditions and determines that the medical image can be used for diagnosis. Re-photographing until judged in the process. Imaging conditions (referred to as re-imaging conditions) when re-imaging medical images (referred to as diagnostic images) determined to be usable for diagnosis in the imaging process are diagnosed by changing the settings from the imaging conditions This is extremely important information indicating whether or not an image can be photographed, and is information useful for learning equivalent to or more than the photographed image and photographed photographing condition.

However, in Japanese Patent Laid-Open No. 2009-268586, although a failed image and a photographed shooting condition are associated with each other, these are not associated with a reshooting condition. For this reason, when the photographer tries to refer to a re-shooting condition related to a certain failed image and the failed shooting condition, the photographer has to find out the corresponding re-shooting condition from among a large number of shooting conditions. It took a lot of time and effort.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and is a failure information management device and a failure that can refer to a failed image, a failed shooting condition, and a reshooting condition without taking time and effort.

In addition, it is preferable to include a communication control unit that causes the external device to transmit the failure information and the re-photographing information searched by the search unit via the communication unit.

If the identification information and re-imaging information include patient identification information that identifies individual patients and patient attribute information that indicates patient attributes, the patient attribute information should be left out of the impairment information and re-imaging information. It is preferable to provide a deletion unit that deletes patient identification information.

It is preferable that the patient identification information includes a patient ID and a patient name given to each patient, and the patient attribute information includes gender, age, height, and weight.

It is preferable that the association processing unit associates the failure information and the reshooting information by giving a common case ID to the failure information and the reshooting information. The case ID is preferably an ID of a photographing order that instructs the photographer to perform photographing.

Also, the copy failure information management method of the present invention includes a reception step and an association processing step. In the reception step, the reception unit receives the failure information and the re-shooting information. The failure information includes a failure image and a failure shooting condition that is a shooting condition when the failure image is shot. The re-photographing information includes a re-photographing condition that is a photographing condition when the diagnostic image is photographed in the re-photographing after the failed image is photographed.

The examination reservation information is issued on the electronic medical record of the clinical department terminal 18 by the medical department doctor. The examination reservation information includes various examination reservations such as blood tests and endoscopic examinations, as well as examination reservations for radiography, and an imaging order 20 for instructing radiographing to a photographer R (doctor, radiographer, etc.). including.

The patient information 21 is stored in the HIS 11. The patient information 21 is registered in the electronic medical chart and includes patient identification information 22 for identifying individual patients and patient attribute information 23 indicating patient attributes.

The RIS 12 receives the imaging order 20 from the medical department terminal 18 and stores and manages it. The RIS 12 transmits the imaging order 20 to the radiology terminal 24. The radiology terminal 24 includes a display 25 that displays the imaging order 20 from the RIS 12.

The radiation imaging system 14, as is well known, receives a radiation source 30 that irradiates radiation (for example, X-rays) toward a patient P to be imaged, and receives radiation emitted from the radiation source 30 and transmitted through the patient P. A radiation image detection device 32 that detects an image 31 and a console 33 that controls driving of the radiation image detection device 32 are provided.

The console 33 has a display 34 and an input device 35. The display 34 displays various operation screens according to the operation of the input device 35 such as a mouse or a keyboard. The operation screen has an operation function by GUI (Graphical User Interface). The console 33 receives an operation instruction input from the input device 35 through the operation screen.

The display 34 displays an operation screen for setting the imaging condition 36 according to the imaging order 20 and the radiation image 31 received from the radiation image detection device 32. The input device 35 is operated when setting the shooting condition 36. The imaging conditions 36 are tube voltage, tube current, and radiation irradiation time applied to the radiation source 30 (see FIG. 5).

Also, the input device 35 is operated during the image inspection process. In the imaging process, the photographer R determines whether the radiation image 31 displayed on the display 34 is a failed image 31F (see FIG. 6) unsuitable for diagnosis or a diagnostic image 31S (see FIG. 6) usable for diagnosis. The result determined by is input. The failed image 31 F is a radiation image 31 that has failed to be imaged due to a setting error of the imaging condition 36 by the photographer R. When the determination that the radiographic image 31 displayed on the display 34 is the diagnostic image 31S is input, this is a signal that radiography for the radiographing order 20 has been completed.

The console 33 creates a radiation image file 40 that associates the radiation image 31 with the photographing condition 36 when the radiation image 31 is photographed and other information, and transmits the created radiation image file 40 to the PACS 13 and the imaging case management apparatus 16. . The PACS 13 stores and manages the radiation image file 40 from the console 33. The failure case management apparatus 16 stores and manages the failure case 84 (see FIG. 10).

The portable information terminal 15 is a portable terminal such as a mobile phone, a smartphone, a tablet terminal, a PDA (Personal Digital Assistant), and a notebook computer, and is carried by the photographer R. The portable information terminal 15 includes a touch panel 41. The touch panel 41 receives an input of an operation instruction based on the movement of the photographer R's finger. The operation instruction includes an instruction to input a search key for searching for a desired failure case 84 and an instruction to issue a transmission request 86 (see FIG. 10) of the failure case 84 including the search key to the failure case management device 16. is there. Further, the touch panel 41 displays various operation screens such as a damage case browsing window 90 (see FIG. 11) based on the damage case 84 transmitted from the damage case management apparatus 16 in response to the transmission request 86.

2, the imaging order 20 has items of order ID (Identification Data) 43, doctor ID, patient ID, and imaging region / posture / orientation. The order ID 43 is a number for identifying each photographing order 20. The order ID 43 is automatically given by the RIS 12 when the imaging order 20 is received from the clinical department terminal 18. The doctor ID is a number for identifying the doctor in the medical department who issued the imaging order 20. The patient ID is a number for identifying an individual patient. The patient ID is a part of the patient identification information 22 and is automatically assigned by the HIS 11 when the patient first visits. The patient ID described in the imaging order 20 is the patient ID of the patient P to be imaged in the radiography by the imaging order 20.

The imaging part / posture / orientation is the part, posture, and orientation of the patient P taken by radiography and directed to the radiation source 10, as instructed by a doctor in the medical department. There are various parts of the human body such as the head, cervical spine, chest, abdomen, hands, fingers, elbows, and knees. The posture includes standing, lying, sitting, etc., and the direction includes front, side, back, and the like. In addition to these items, the imaging order 20 includes the date and time when the imaging order 20 was received at the RIS 12, the purpose of radiography such as follow-up after surgery, items to be delivered from the doctor in the medical department to the photographer R, etc. Items are provided.

The RIS 12 creates the order management list 45 shown in FIG. 3 and manages the accepted imaging order 20. The order management list 45 includes items such as the photographer ID of the photographer R who is in charge of radiography and the progress status in addition to the items of the photographing order 20. The photographer ID is a number for identifying each photographer R. The progress status includes any of radiographed images indicating that radiography of the radiographing order 20 has been completed, radiographing during radiographic imaging, and radiographic imaging not being performed. Is marked. The RIS 12 updates the progress status item in response to a signal from the console 33 indicating the end of radiation imaging.

Note that, as shown in FIG. 3, there may be one imaging order 20 for one patient or a plurality of imaging orders 20 may be issued simultaneously for one patient. When a plurality of imaging orders 20 are issued for one patient at the same time, the RIS 12 adds the same identification code indicating that they are issued simultaneously after the order ID 43 of the plurality of imaging orders 20. The imaging order 20 is associated.

4, patient information 21 includes items such as patient ID, patient name, sex, date of birth, age, height (unit cm), weight (unit kg), and the like. The patient ID and the patient name constitute the patient identification information 22, and the sex, date of birth, age, height and weight other than these constitute the patient attribute information 23, respectively. The age is automatically calculated from the date of birth. In addition to the above, the patient's address or telephone number may be added as the patient identification information 22. Further, as the patient attribute information 23, a physique index such as a BMI (Body Mass Index) index calculated from the height and weight may be added.

5, the radiation image file 40 has a file format conforming to, for example, DICOM (Digital Imaging and Communication in Medicine) standards, and includes a tag storage area 50 and a radiation image storage area 51. In the tag storage area 50, patient information 21 including the above-described patient identification information 22 and patient attribute information 23, order ID 43, imaging region / posture / orientation, radiographer ID, tube voltage (unit kV), tube current ( Each item includes a unit mA), an imaging condition 36 including a radiation irradiation time (unit msec), and a failure flag 52. In the imaging process, “1” is assigned to the failure flag 52 when a determination result that the radiation image 31 displayed on the display 34 is the failure image 31F is input.

Further, the tag storage area 50 is provided with items of file ID and shooting date / time. The file ID is a number for identifying each radiation image file 40 and is automatically assigned by the console 33 when the radiation image file 40 is created. The radiation image 31 is stored in the radiation image storage area 51.

In radiography, there may be a case where a photograph loss occurs due to an erroneous setting of the photographing condition 36 by the photographer R. In the case where the image loss occurs, the photographer R resets the image capturing condition 36 and performs re-imaging until a diagnostic image 31S that can be used for diagnosis is captured. For this reason, when a copy loss occurs, a plurality of radiation image files 40 are created for one imaging order 20. On the other hand, when there is no image loss (when the diagnostic image 31S is captured by one radiation imaging), one radiation image file 40 is provided for one imaging order 20. In the following, the radiographic image file 40 created when the imaging failure occurs is taken as the imaging image file (corresponding to the imaging information) 40F, and the radiographic image file 40 created when the diagnostic image 31S is obtained is used for diagnosis. It is expressed as an image file (corresponding to re-shooting information) 40S.

As shown in FIG. 6, the failed image file 40F contains a radiographic image 31 that has failed to be photographed due to a mistake in setting of the photographing condition 36 by the photographer R and has been determined to be unsuitable for diagnosis in the imaging process. A lossy image 31F and a lossy shooting condition 36F that is a shooting condition 36 when the lossy image 31F is shot are stored. On the other hand, in the diagnostic image file 40S in the case where a failure occurs, the diagnosis is a radiation image 31 obtained by re-imaging after the shooting of the failed image 31F and determined to be usable for diagnosis in the imaging process. The re-imaging condition 36S, which is the imaging condition 36 when the diagnostic image 31S and the diagnostic image 31S are captured, is stored. Since the failed image file 40F and the diagnostic image file 40S are created for one imaging order 20, the same order ID 43 is assigned to these

files

40F and 40S. That is, these

files

40F and 40S are related by the order ID 43.

“1” is attached to the failure flag 52 of the failure image file 40F. On the other hand, nothing is attached to the failure flag 52 of the diagnostic image file 40S. By referring to the failure flag 52, the radiation image file 40 can distinguish between the failure image file 40F and the diagnostic image file 40S.

7, the computer constituting the console 33 includes a storage device 55, a memory 56, a CPU (Central Processing Unit) 57, and a communication unit 58 in addition to the display 34 and the input device 35 described above. These are interconnected via a data bus 59.

The storage device 55 is, for example, a hard disk drive built in a computer constituting the console 33. The storage device 55 stores a control program such as an operating system and various application programs including the first failure information management program 60. The first copy information management program 60 is a program for causing a computer constituting the console 33 to function as a copy information management apparatus.

The memory 56 is a work memory for the CPU 57 to execute processing. The CPU 57 loads the program stored in the storage device 55 into the memory 56 and executes processing according to the program, thereby comprehensively controlling each part of the computer.

The communication unit 58 is a network interface that transmits various types of information to and from an external device via the network 17. The communication unit 58 receives the radiographing order 20 from the radiology terminal 24, the patient information 21 from the HIS 11, and the radiographic image 31 from the radiographic image detection device 32, and the diagnostic image file 40S to the PACS 13 and the failed image. The file 40F and the diagnostic image file 40S are respectively transmitted to the failure case management apparatus 16.

In FIG. 8, the CPU 57 functions as the accepting unit 65 and the association processing unit 66 in cooperation with the memory 56 when the first failure information management program 60 is activated.

The accepting unit 65 accepts the imaging order 20 from the radiology terminal 24 received by the communication unit 58, the patient information 21 from the HIS 11, and the radiation image 31 from the radiation image detection device 32. The accepting unit 65 accepts the photographing condition 36 input by the photographer R via the input device 35. The accepting unit 65 delivers the imaging order 20, the patient information 21, the radiation image 31, and the imaging condition 36 to the association processing unit 66.

The association processing unit 66 is based on the order ID 43, the imaging part / posture / orientation, the photographer ID, the patient information 21, the radiation image 31, and the imaging condition 36 of the imaging order 20 from the reception unit 65. Create The association processing unit 66 causes the created radiographic image file 40 and its storage request to be transmitted to the PACS 13 and the imaging failure case management apparatus 16 via the communication unit 58.

The association processing unit 66 associates the failed image file 40F and the diagnostic image file 40S with the order ID 43. More specifically, the association processing unit 66 passes the new imaging order 20 from the receiving unit 65 until the radiograph 31 is determined as the diagnostic image 31S by the photographer R in the imaging process. The same order ID 43 is attached to the radiation image file 40. That is, the plurality of radiographic image files 40 to which the same order ID 43 is attached is a group of at least one failed image file 40F and one diagnostic image file 40S. The association processing unit 66 adds “1” to the failure flag 52 of the failure image file 40F in order to distinguish it from the diagnostic image file 40S.

In FIG. 9, the computer configuring the image loss case management apparatus 16 has the same configuration as the console 33 of FIG. 7 except that the display 34 and the input device 35 are not provided, and includes a storage device 70, a memory 71, and a CPU 72. , A communication unit 73, and a data bus 74 interconnecting them.

The storage device 70 stores a second copy information management program 75 for causing a computer constituting the copy case management device 16 to function as a copy information management device. That is, in the present embodiment, the failure case management device 16 and the console 33 constitute a failure information management device.

The communication unit 73 receives the failed image file 40F and the diagnostic image file 40S and the storage request from the console 33. In addition, the communication unit 73 receives the transmission request 86 of the failure case 84 in which the failed image file 40F and the diagnostic image file 40S are collected from the portable information terminal 15, and transmits the transmission request 86. 15 is transmitted as a copy failure example 84.

In FIG. 10, when the second copy information management program 75 is activated, the CPU 72 functions as a communication control unit 80, a creation unit 81, and a search unit 82 in cooperation with the memory 71.

The communication control unit 80 controls transmission of various information via the communication unit 73. The creation unit 81 creates various databases (DB; Data Base) in which various information can be searched using a search key in the storage device 70. The search unit 82 searches the DB for information corresponding to a transmission request from an external device such as the transmission request 86 from the portable information terminal 15. The communication control unit 80 causes the information retrieved by the retrieval unit 82 to be transmitted to the external device that has transmitted the transmission request via the communication unit 73.

The communication control unit 80 receives the failed image file 40F and the diagnostic image file 40S received from the console 33 via the communication unit 73, and the storage request thereof. The communication control unit 80 delivers the received failed image file 40F and the diagnostic image file 40S to the creation unit 81.

The creating unit 81 sets the failed image file 40F and the diagnostic image file 40S, which are associated with the same order ID 43 from the communication control unit 80, as a group of failed case 84. The creation unit 81 creates a failure case DB 85 in the storage device 70 that can search for the failure case 84 using a search key.

The communication control unit 80 receives the transmission request 86 from the portable information terminal 15 received via the communication unit 73 and passes it to the search unit 82. The search unit 82 searches for a failure case 84 corresponding to the transmission request 86 from the failure case DB 85. The search unit 82 delivers the searched failure example 84 to the communication control unit 80. The communication control unit 80 causes the portable information terminal 15 that has transmitted the transmission request 86 to transmit the failure example 84 from the search unit 82 via the communication unit 73.

As a search key included in the transmission request 86, it is possible to specify arbitrary items stored in the tag storage area 50 of the radiation image file 40 such as an order ID 43, an imaging date and time, a patient ID, and the like. Further, for example, it is possible to specify a search range, such as specifying all the lost cases 84 whose shooting date and time is one week ago, and the lost cases where the photographer ID is R0001 and the patient's weight is 100 kg or more. It is also possible to perform a so-called AND search or OR search using a plurality of items such as 84.

Although illustration is omitted, the computer constituting the PACS 13 has the same configuration as the failure case management apparatus 16 shown in FIG. 9, and the CPU of the computer constituting the PACS 13 is also the same as that of the failure case management apparatus 16 shown in FIG. The same functional unit as the CPU 72 is included. However, the difference is that the information handled by the PACS 13 is only the diagnostic image file 40S.

The creation unit of the PACS 13 creates, in the storage device, an image DB that can search the diagnostic image file 40S using a search key instead of the failure case DB 85 of the failure case management apparatus 16. The search unit of the PACS 13 receives a diagnostic image file from the image DB in response to a transmission request for the diagnostic image file 40S from the clinical department terminal 18 or a radiology department terminal that has an interpretation doctor responsible for interpretation of the diagnostic image 31S. Search 40S. The communication control unit of the PACS 13 accepts the diagnostic image file 40S from the console 33 and a storage request thereof, and the transmission request of the diagnostic image file 40S from the clinical department terminal 18 or the interpretation department terminal. The communication control unit of the PACS 13 causes the diagnostic image file 40S searched by the search unit to be transmitted via the communication unit to the clinical department terminal 18 or the interpretation department terminal that has transmitted the transmission request.

The portable information terminal 15 displays a failure case browsing window 90 shown in FIG. 11 on the touch panel 41 based on the failure case 84 received from the failure case management device 16. The photographed case browsing window 90 includes display frames 91, 92, 93, and 94 for displaying the photographed image 31F, the photographed photographing condition 36F, the diagnostic image 31S, and the re-photographing condition 36S, respectively. By these display frames 91 to 94, the photographed image 31F and the photographed imaging condition 36F, and the diagnostic image 31S and the reimaging condition 36S are displayed so that the photographer R can compare them. The display frames 91 and 92 for displaying the failed image 31F and the failed imaging condition 36F are vertically arranged, and the display frames 93 and 94 for displaying the diagnostic image 31S and the re-imaging condition 36S are also vertically arranged. Further, the display frames 91 and 92 and the display frames 93 and 94 are arranged on the left and right so as to be comparable. Above the display frames 91 and 93, a display frame 95 for displaying the file ID and a display frame 96 for displaying the shooting date and time are provided.

In addition to the display frames 91 to 96, the image display window 91 for displaying a case of damage is a display frame 97 for displaying an order ID 43, an imaging region / posture / orientation, and a photographer ID, and a display frame 98 for displaying patient information 21. Is provided. The display frame 98 is further divided into a display frame 99 for displaying the patient identification information 22 and a display frame 100 for displaying the patient attribute information 23.

The direction of the arrow is upward when the value of the re-shooting condition 36 is higher than the value of the shooting condition 36, downward when it is lowered, and sideways when the value does not change.

Hereinafter, the operation of the above configuration will be described with reference to the flowcharts of FIGS. First, an imaging order 20 is issued from the clinical department terminal 18 to the RIS 12 by the medical department doctor. The imaging order 20 is transmitted from the RIS 12 to the radiology terminal 24 and displayed on the display 25 of the radiology terminal 24.

The photographer R confirms the photographing order 20 from the RIS 12 on the display 25 and transfers it to the console 33. Then, the imaging condition 36 corresponding to the confirmed imaging order 20 is set in the console 33 via the input device 35. The photographer R positions the radiation source 30, the radiation image detection device 32, and the patient P to desired positions, and then drives the radiation source 30 to irradiate the patient P with radiation. The radiation that has passed through the patient P is applied to the radiation image detection device 32, whereby the radiation image detection device 32 detects the radiation image 31. The radiation image 31 is transmitted from the radiation image detection device 32 to the console 33.

As shown in step S10 of FIG. 12, the console 33 receives the imaging order 20 from the radiology terminal 24 received by the communication unit 58, patient information 21 from the HIS 11, and a radiological image 31 (photographing from the radiological image detection device 32). Any one of the damaged image 31F and the diagnostic image 31S) and the imaging condition 36 (any one of the imaging failure condition 36F and the re-imaging condition 36S) input by the photographer R via the input device 35 are input to the reception unit 65. Accepted. These pieces of information received by the receiving unit 65 are transferred to the association processing unit 66. The patient information 21 is transmitted via the communication unit 58 to the HIS 11 as a search request for the patient information 21 of the patient ID using the patient ID of the imaging order 20 received by the receiving unit 65 as a search key. The patient information 21 corresponding to is acquired by receiving from the HIS 11.

In step S11, the association processing unit 66 creates the radiation image file 40 (either the failed image file 40F or the diagnostic image file 40S) based on the information delivered from the receiving unit 65. Until the radiographic image file 40 is determined to be the diagnostic image 31S by the photographer R in the imaging process after the new imaging order 20 is delivered from the receiving unit 65 to the radiographic image file 40 by the association processing unit 66. The same order ID 43 is assigned. By doing so, the failed image file 40F and the diagnostic image file 40S created when a failure occurs are associated by the order ID 43.

In step S12, the radiation image file 40 created by the association processing unit 66 is requested to save the diagnostic image file 40S to the PACS 13 and the failed image file 40F and the diagnostic image file 40S to the failed case management apparatus 16, respectively. At the same time, it is transmitted via the communication unit 58.

In the PACS 13, the diagnostic image file 40S from the console 33 is stored in the image DB.

In the failure case management apparatus 16, the communication unit 73 receives the failure image file 40 F and the diagnostic image file 40 S from the console 33. As shown in step S20 of FIG. 13, the failed image file 40F and the diagnostic image file 40S received by the communication unit 73 are received by the communication control unit 80. The failed image file 40F and the diagnostic image file 40S received by the communication control unit 80 are transferred to the creation unit 81.

As shown in step S21, the failed image file 40F and the diagnostic image file 40S associated with the same order ID 43 from the communication control unit 80 are made the failed case 84 by the creating unit 81 and stored in the failed case DB 85. Is done.

The photographer R operates the portable information terminal 15 to transmit a transmission request 86 for the failure case 84 to the failure case management device 16. As shown in step S 30 of FIG. 14, the transmission request 86 from the portable information terminal 15 is received by the communication unit 73 and accepted by the communication control unit 80. The transmission request 86 received by the communication control unit 80 is transferred to the search unit 82.

As shown in step S31, the retrieval unit 82 retrieves the failure case 84 corresponding to the transmission request 86 from the failure case DB 85. The failed image file 40F and the diagnostic image file 40S are associated with each other by the order ID 43, and the failed case DB 85 for storing the failed case 84 in which these

files

40F and 40S are collected together is created. The failure example 84 corresponding to the request 86 can be easily retrieved.

The failure example 84 retrieved by the retrieval unit 82 is delivered to the communication control unit 80. Then, as shown in step S 32, the failure example 84 is transmitted by the communication control unit 80 to the portable information terminal 15 that has transmitted the transmission request 86 via the communication unit 73.

In the portable information terminal 15, a failure case browsing window 90 based on the failure case 84 from the failure case management device 16 is displayed on the touch panel 41. The photographer R browses the failure case browsing window 90 and learns to find an improvement point in the setting of the photographing condition 36 of the photographer R.

By associating the failed image file 40F and the diagnostic image file 40S, not only the failed image 31F and the failed imaging condition 36F but also the diagnostic image 31S and the reimaging condition 36S can be easily referred to. Therefore, as compared with the case where only the failed image 31F and the failed photographing condition 36F are referred to, learning for improving the setting of the photographing condition 36 progresses, and it can contribute to the improvement of the photographing technique of the photographer R. .

The photographer R instantly searches for and transmits the failure case 84 corresponding to the transmission request 86 from the portable information terminal 15, so that the photographer R repeatedly refers to the failure case 84 that he / she is interested in regardless of the date / time and location. can do. For this reason, it is possible to spend free time such as intervals between radiography and commuting hours. Further, when setting the imaging condition 36, the imaging condition 36 is set to the imaging condition 36, such as referring to the past imaging example 84 of the patient P to be imaged or the imaging example 84 having a physique similar to the patient P. You can also help.

When there is a transmission request for the diagnostic image file 40S from the medical department terminal 18 or the interpretation department terminal to the PACS 13, the corresponding diagnostic image file 40S is searched from the image DB by the search unit, and the searched diagnostic image is searched. The file 40S is transmitted to the clinical department terminal 18 or the radiology department terminal via the communication unit. The diagnostic image 31S of the diagnostic image file 40S transmitted to the interpretation department terminal is used for interpretation by the interpretation doctor. Further, the diagnostic image 31S of the diagnostic image file 40S transmitted to the clinical department terminal 18 is used for diagnosis of the medical department doctor together with the report created by the interpretation doctor.

In the first embodiment, the console 33 is stored with the first copy information management program 60 to have the functions of the receiving unit 65 and the association processing unit 66, and the copy case management apparatus 16 has the second copy information management program. 75 is stored, and the functions of the communication control unit 80, the creation unit 81, and the search unit 82 are carried out. However, a failure information management program in which the first and second failure

information management programs

60 and 75 are integrated is displayed on the console 33. And the console 33 may have all the functions of the reception unit 65, the association processing unit 66, the communication control unit 80, the creation unit 81, and the search unit 82. In this case, the storage unit that stores the failure case 84 is handled by the storage device 55 of the console 33 instead of the storage device 70 of the failure case management apparatus 16 of the first embodiment.

The PACS 13 is used for storing and managing the diagnostic image file 40S. The PACS 13 is provided with a failure case management apparatus 16 for storing and managing the failure cases 84 separately from the PACS 13. The function of the device 16 may be performed. As described above, in the failure information management apparatus of the present invention, each functional unit may be distributed and arranged in a plurality of computers, or each functional unit is collectively arranged in one computer. Also good.

In the first embodiment, the failure case 84 searched by the search unit 82 is transmitted to the portable information terminal 15 by the communication control unit 80 via the communication unit 73, and the failure case 84 is browsed by the portable information terminal 15. However, an input device for inputting the search key for the failure case 84 and a display for displaying the searched failure case 84 are provided in the failure case management device 16, and the photographer R can use only the portable information terminal 15. Alternatively, the failure example 84 may be browsed via the failure case management device 16.

[Second Embodiment]
In the first embodiment, the diagnostic image 31S is included in the diagnostic image file 40S corresponding to the re-imaging condition. However, the diagnostic image 31S also exists in the diagnostic image file 40S stored in the PACS 13. Further, if there is only the failed image 31F, the fundamental reason indicating why the image is lost, such as the image density being low, can be understood. For this reason, the diagnostic image 31S is not so necessary for learning to search for an improvement in the setting of the imaging condition 36. Therefore, the diagnostic image file 40S of the copy failure example 84 only needs to include at least the re-imaging condition 36S.

Therefore, in the present embodiment, as illustrated in FIG. 15, the diagnostic image 31S in the diagnostic image file 40S is deleted when the creation unit 81 stores the failure case 84 in the failure case DB 85. If it is desired to refer to the diagnostic image 31S together with the imaging condition 36F or the like, the diagnostic image 31S may be transmitted from the PACS 13. Accordingly, there is no practical problem even if the diagnostic image 31S is deleted from the copy failure example 84.

[Third Embodiment]
As in the case of the first embodiment, when the failure case browsing window 90 is displayed on the touch panel 41 of the portable information terminal 15, the failure case 84 can be easily referred to, but is displayed on the failure case browsing window 90. There is a risk that the recorded information may be stolen by a third party other than the photographer R. Of the information displayed in the copy case browsing window 90, the information that should never be stolen by a third party is the patient identification information 22 displayed in the display frame 99. On the other hand, the patient attribute information 23 displayed in the display frame 100 is necessary for learning to find an improvement in the setting of the imaging condition 36 because the setting of the imaging condition 36 changes depending on the sex, age, height, and weight (physique). Information.

Therefore, in the present embodiment, as shown in FIG. 16, patient attribute information 23 that is necessary for learning is left from a failed image file 40F and a diagnostic image file 40S, and patient identification that is difficult to be stolen by a third party is difficult. A deletion unit 110 that deletes the information 22 is provided. For example, the deletion unit 110 deletes the patient identification information 22 from the failure image file 40F and the diagnostic image file 40S of the failure case 84 created by the creation unit 81, and stores the patient identification information 22 in the failure case DB 85. By doing this, the patient identification information 22 is not displayed in the failure case browsing window 90, and there is no fear that the patient identification information 22 is stolen by a third party.

Note that the timing for deleting the patient identification information 22 is not the method of deleting the case 84 when storing the case 84 in the case DB 85 as described above. It may be deleted when handing over to the control unit 80, or may be deleted when displaying the failure case browsing window 90 on the portable information terminal 15 side. That is, the function of the deletion unit 110 may be performed by the image loss case management device 16 or the portable information terminal 15. When the mobile information terminal 15 has the function of the deletion unit 110, the mobile information terminal 15 also constitutes a copy failure information management device.

[Fourth Embodiment]
In the first embodiment, the failed image file 40F and the diagnostic image file 40S are associated by the order ID 43, but the present invention is not limited to this. As in the association processing unit 115 shown in FIG. 17, by assigning a case ID 116 different from the order ID 43 to the failed image file 40F and the diagnostic image file 40S, the failed image file 40F and the diagnostic image file 40S are obtained. You may associate.

Further, instead of attaching a common case ID such as the order ID 43 and the like, the failed image file 40F and the diagnostic image file 40S may be associated by being integrated into one file format.

In the first embodiment, the radiograph 31 is subjected to image analysis, although it is left to the photographer R himself to determine whether or not the cause of taking the failed image 31F is a setting error of the imaging condition 36. Thus, it may be possible to automatically determine whether or not the cause of shooting the failed image 31F is a setting error of the shooting condition 36.

Possible causes of the image loss other than the setting mistake of the shooting condition 36 by the photographer R include a shake due to the body movement of the patient P during radiography and a positioning error of the patient P. Therefore, first, shake due to body movement of the patient P is detected from the radiation image 31, and then a positioning error is detected. If it is neither of them, it is determined that the cause of shooting the failed image 31F is a setting error of the shooting condition 36.

As a method for detecting shake due to body movement of the patient P, for example, a method for detecting the size of image blur by detecting edges included in an image in a plurality of directions, as described in JP-A-2007-175138 Can be adopted. In addition, as a method of detecting a positioning error of the patient P, for example, a radiographic image obtained in a normal positioning is stored in advance for each imaging region / posture / orientation, The similarities can be calculated by comparing the radiographic images 31 obtained in the above, and when the similarity is lower than the threshold value, it is possible to adopt a method of determining that the patient P is positioned incorrectly. Here, although it is automatically determined whether or not the cause of shooting the failed image 31F is a setting error of the imaging condition 36, the radiation image 31 is a failed image 31F that is not suitable for diagnosis. The imaging process for determining whether or not there is is performed visually by the photographer R to the last.

Note that the imaging process is not performed by the photographer R using the console 34 as in the first embodiment, but may be performed by a medical staff other than the photographer R using a terminal different from the console 34.

Note that when the photographer R tries to set a shooting condition 36 that is the same as or similar to the failed shooting condition 36F, a warning that prompts the user to change the shooting condition 36 may be displayed. More specifically, a transmission request for the failed imaging condition 36F of the failed image file 40F of the patient ID using the patient ID of the imaging order 20 received by the receiving unit 65 as a search key is managed from the console 33. The failure photographing condition 36F corresponding to the transmission request is transmitted from the failure case management device 16 to the console 33. Then, the image capturing condition 36F transmitted from the image capturing case management apparatus 16 is compared with the image capturing condition 36 input by the photographer R via the input device 35, and these are the same or the difference is within a predetermined range. If it is, a warning is displayed on the display 34.

Note that, as shown in the above embodiments, the present invention extends to a program form and further to a storage medium for storing the program. Further, the present invention is not limited to the above-described embodiments, and various configurations can be adopted without departing from the gist of the present invention. For example, an MRI imaging system may be provided as a modality for imaging medical images instead of or in addition to the radiation imaging system 14. Further, the radiographic image 31 and the imaging condition 36 may not be collected in a file format like the radiographic image file 40. Furthermore, although one diagnostic image file 40S has been described for one imaging order 20, a plurality of diagnostic image files 40S may be provided for one imaging order 20. Further, the failed image file 40F and the diagnostic image file 40S are grouped together as a failed case 84, and the failed case 84 is stored in the failed case DB 85. A DB for storing the diagnostic image file 40S may be provided separately.
