[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a data editing apparatus and a data editing method, and more particularly, to an imaging condition editing mechanism in an image acquisition / display apparatus used for diagnosis of medical image data, an imaging condition editing method using the image acquisition / display apparatus, and an imaging condition. It relates to an array program.
[0002]
[Prior art]
Radiation images acquired using radiation such as X-rays are widely used as medical images for diagnosing diseases. For example, a phosphor layer (phosphor screen) is irradiated with X-rays transmitted through a subject, and the phosphor layer In the past, so-called radiographs have been used, in which visible light generated in step 1 is irradiated onto a film using a silver salt in the same manner as in ordinary photographs.
[0003]
However, in recent years, a radiation image conversion method for directly extracting a radiation image as a digital signal from a radiation detector such as a stimulable phosphor or FPD (Flat Panel Detector) without using a film coated with silver salt has been used. It is becoming. Furthermore, various image processes have been performed for the purpose of making the radiographic image obtained by the radiographic image conversion method more suitable for diagnosis.
[0004]
Specifically, for example, in US Pat. No. 3,859,527 and JP-A-55-12144, there is a radiation image conversion method using a stimulable phosphor and using visible light or infrared light as stimulated excitation light. It is disclosed. This method uses a radiation image conversion panel in which a photostimulable phosphor layer is formed on a support, and the radiation transmitted through the subject is applied to the photostimulable phosphor layer to transmit the radiation through each part of the subject. After the radiation energy corresponding to the amount is accumulated to form a latent image, the accumulated radiation energy is used as the stimulating light by scanning the stimulable phosphor layer with stimulating excitation light such as laser light of a predetermined wavelength. The light is emitted, and the stimulated light is photoelectrically converted using a photoelectric conversion element such as a photomultiplier to be taken out as an electric signal.
[0005]
Radiation imaging diagnostic systems using stimulable phosphors are commonly referred to as computed radiography (CR), and can be broadly divided into standing / recumbent position types that contain stimulable phosphors in readers. And a cassette type system in which a portable cassette containing a stimulable phosphor and a reading device for extracting and reading the phosphor from the cassette are combined.
[0006]
Even when radiographic imaging is performed with any of the above radiographic diagnostic systems, it is necessary to select an appropriate imaging condition from a number of imaging conditions such as a body part and an imaging direction. The selection is usually performed by a controller that inputs patient information and displays captured image data.
[0007]
In the display unit of the controller, the large number of shooting conditions are classified into a plurality of pages and displayed for each page. Then, by using the “Previous Page” and “Next Page” buttons, the pages are moved forward and backward to find a page that includes the imaging conditions that you want to select, and the imaging conditions that are appropriate for the patient's imaging are displayed from the displayed imaging conditions. select. In addition, when there are a large number of shooting conditions, some shooting conditions have a hierarchical structure in order to organize the shooting conditions, and the target shooting conditions can be reached by selecting options for each layer. be able to.

[Problems to be solved by the invention]
In the selection of imaging conditions in the radiological image diagnosis system, in a method in which a plurality of pages are sequentially sent to search for a page including a desired imaging condition, and the imaging condition is selected from among the pages, as the imaging conditions increase, the pages on the back There is a problem in that a large number of key operations are required when selecting the shooting conditions included in the, and lack of quickness. In addition, as the number of key operations increases, the possibility of selecting an erroneous shooting condition increases.
[0010]
Also, in the method of extracting desired shooting conditions by making the shooting conditions into a hierarchical structure and selecting from the choices for each layer, the hierarchy increases as the number of shooting conditions increases, and the desired shooting conditions are achieved. The number of key operations to reach will also increase. In addition, there is a large difference in the selection frequency in the imaging conditions in the radiological image diagnostic system, and there are some that are selected very well and those that are hardly selected. However, when shooting conditions have a hierarchical structure, a certain number of key operations are always required when selecting shooting conditions, regardless of the frequency of selection. However, there is a problem that it takes the same time as selecting an imaging condition that is hardly selected.
[0011]
The radiological image diagnosis system is used in a medical field such as a hospital, and there is also a demand to make a diagnosis immediately after imaging, and the entire system is required to be quick. In addition, the radiological image diagnostic system may be used at the time of mass screening, and in such a case, further rapidity is required. In addition, since radiation is harmful to the human body, it is necessary to avoid re-imaging due to imaging failure as much as possible.
[0012]
Therefore, it is necessary to select the shooting conditions in a short time. To that end, it may be possible to reduce the number of shooting conditions displayed. However, if the required shooting conditions are not displayed, shooting itself can be performed. It will disappear. On the other hand, the shooting conditions required by the user vary, and many shooting conditions that are not used are included in the shooting condition group extracted and selected from the master data covering all shooting conditions. Further, the shooting conditions to be displayed change with continuous use, and it is necessary to edit the shooting condition group itself in order to always display appropriate shooting conditions.
[0013]

[0026]
【Example】
In order to describe the above-described embodiment of the present invention in more detail, an example of the present invention will be described with reference to FIGS. FIG. 1 is a diagram showing an overall configuration of a radiological image diagnostic system, and FIG. 2 is a block diagram showing a configuration of an image acquisition and display device that constitutes the radiographic image diagnostic system. FIGS. 3 to 11 are diagrams showing examples of screens displayed on the controller.
[0027]
In the following description, a case where an imaging condition editing mechanism, which is a feature of the present invention, is provided in a controller of a cassette type image acquisition / display apparatus will be described. However, a system using a radiation image conversion medium other than a cassette Or a system dedicated to a standing or lying position that does not use a radiographic image conversion medium, or a system of any device that displays a medical image such as a system that directly extracts a radiographic image as a digital signal using a radiation detector such as an FPD It is also possible to provide the editing mechanism in an editing apparatus that operates by being connected to these medical image apparatuses via a network.
[0028]
First, in order to facilitate understanding of the imaging condition editing mechanism, which is a feature of the present invention, the configuration of the radiation image diagnostic system and the image acquisition / display apparatus and the imaging procedure using the radiation image diagnostic system will be outlined.
[0029]
As shown in FIGS. 1 and 2, the radiological image diagnosis system 1 includes an X-ray imaging apparatus 2 that performs X-ray imaging and an image acquisition display apparatus 6 that reads and displays the captured X-ray image. In the apparatus 2, X-rays irradiated from the X-ray irradiation apparatus 3 including an X-ray tube pass through the subject 4 and irradiate a radiation image conversion medium such as a radiation image conversion panel 5 a built in the cassette 5. This radiation image conversion panel 5a has a photostimulable phosphor layer, and when this photostimulable phosphor is irradiated with X-rays, a part of the energy of the X-rays becomes the amount of X-ray irradiation. Accordingly, it is stored as a latent image in the photostimulable phosphor.
[0030]
Then, after X-ray imaging, the cassette 5 containing the radiation image conversion panel 5a on which the latent image is formed is put into the image reading device (reader 7) of the image acquisition display device 6. In the reader 7, the radiation image conversion panel 5 a is taken out from the cassette 5, and when the excitation light irradiation unit 7 a in the reader 7 irradiates the radiation image conversion panel 5 a with excitation light such as visible light or infrared light, the radiation image conversion is performed. The panel 5a emits photostimulated light according to the amount of X-ray energy accumulated in the photostimulable phosphor. The emitted light is input to the photoelectric conversion unit 7c via the filter 7b, and the photoelectric conversion unit 7c converts the optical signal into a voltage signal proportional to the emission intensity and outputs the voltage signal to the A / D conversion unit 7d. The A / D converter 7 b converts the input voltage signal into digital image signal data and outputs the digital image signal data to the controller 8.
[0031]
The controller 8 includes a display unit 8d such as a CRT and an operation unit 8e such as a keyboard and a touch panel. The controller 8 records the digital image signal data sent from the A / D conversion unit 7b in the storage unit 8c, and The data is output to the display unit 8d or the like, or the data is transmitted to the laser imager 9 connected via the DICOM network and output as a film.
[0032]
The controller 8 also includes a control unit 8a that controls the reader 7 based on the set reading conditions, and various image processing (correction processing, gradation conversion processing, trimming, inversion / inversion) on the image read by the reader 7. Rotation, parameter change, masking, etc.) The processing unit 8b, the reception list screen, the search screen, the imaging part selection screen, the imaging routine selection screen, the screen creation unit 8h that creates various screens, and the identification that reads the plate ID of the cassette 5 A label detection unit 8f and photographing condition editing means 8g that enables editing of photographing conditions, which is a feature of the present invention, are provided.
[0033]
In the configuration shown in the figure, the reader 7 and the controller 8 are separated from each other. However, the reader 7 and the controller 8 may be integrated into the image acquisition display device 6. The controller 8 may be connected to a terminal 10 such as HIS or RIS for inputting / outputting patient information from a remote location via a network and a database 11 for storing imaging history information. Furthermore, the editing mechanism of the present invention may be provided in the independent editing device 12.
[0034]
In the above-mentioned cassette type radiographic image diagnosis system 1, in order to clarify the correspondence between the cassette 5 and the reservation information such as patient information, imaging conditions, and reading conditions, the correspondence between the cassette 5 and the reservation information is registered in advance. Either a method of performing imaging later (pre-registration) or a method of associating the cassette insertion order with the input order of the reservation information without registering the cassette 5 before radiation imaging (post-registration) is adopted. Thus, reading of the image data is executed.
[0035]
The pre-registration and the post-registration have their respective characteristics. For example, in a hospital where a large number of readers 7 and controllers 8 are installed in different places, and a large number of radiographers take images, radio images of a large number of patients are obtained by pre-registration. Diagnosis can be performed accurately. On the other hand, a practitioner or the like in which the number of readers 7 and controllers 8 is small and a small number of radiologists perform imaging can perform X-ray imaging quickly and efficiently by post-registration. . Note that the photographing condition editing mechanism, which is a feature of the present embodiment, can be applied to an apparatus that employs any registration method.
[0036]
With reference to the screen configuration examples of FIGS. 3 to 11, a procedure for imaging a patient using the radiological image diagnosis system 1 having the above configuration and performing a diagnosis using the acquired image will be described. The necessity of editing roles and shooting conditions will be described.
[0037]
First, an operator such as a radiologist inputs patient information through the display unit 8d and the operation unit 8e of the controller 8. Here, it is assumed that the search screen 13 shown in FIG. 3 is set as an initial screen. When a predetermined search key is input by operating the keyboard of the input area 13b and the search button is touched or clicked, HIS, RIS, etc. A search is executed with reference to the external information terminal, database, etc., and patient information is displayed in the display area 13a.
[0038]
This patient information can also be obtained from the acceptance list screen 14. In this case, the [acceptance list] button on the search screen 13 is touched to display the acceptance list screen 14 as shown in FIG. The reception list screen 14 displays a list of information such as patient ID, patient name, sex, age, requested department, ward, shooting conditions, number of shots, etc. in the display area 14a. A predetermined patient to perform is selected. Then, when the [OK] button is used to return to the search screen 13 and the [Examination start] button provided on the search screen 13 is selected to start the inspection, an imaging condition selection screen is displayed.
[0039]
This imaging condition is a condition that should be taken into account when capturing a radiographic image, and an appropriate radiographic image can be acquired by imaging based on the selected imaging condition. The imaging conditions include, for example, an imaging region (head, chest, abdomen, neck, waist, spine, lung field, upper limb, lower limb, etc.), an imaging position (standing position, supine position, etc.), an imaging direction (front, side, etc.) ), Patient characteristics (sex, age, physique, etc.), disease name, etc.
[0040]
These many shooting conditions are provided as data covering all the conditions (maker master data) by the manufacturer that provides the system. However, if all of the shooting conditions of several hundreds are displayed on the screen, the screen will be several dozen pages. In addition, it is difficult to quickly select imaging conditions suitable for the patient from such a large number of pages. Therefore, the manufacturer usually extracts only the shooting conditions used by the user from all the shooting conditions, and creates and provides the user with a screen that classifies the extracted shooting conditions so that the operator can easily select them. is doing.
[0041]
A shooting condition selection screen 15 as shown in FIGS. 5 to 8 is displayed as a screen in which shooting conditions are classified. The imaging condition selection screen 15 includes, for example, a setting condition display area 15a for displaying imaging conditions that are particularly frequently used among the extracted imaging conditions using icons 15c, and imaging modes such as imaging positions and imaging regions. There is provided a classification display area 15b for displaying the photographing conditions classified for each. For example, when [Favorite] is selected from the tag of the classification display area 15b, the photographing conditions registered by the user as favorites as shown in FIG. Is displayed, the shooting conditions classified as standing are displayed as shown in FIG. 6, and the shooting conditions classified as lying are displayed as shown in FIG. When [Cassette] is selected, the photographing conditions classified as cassettes are displayed as shown in FIG. Then, the operator selects shooting conditions from the setting condition display area 15a or selects items such as standing, lying, and cassette, and then presses buttons such as [Previous Page] and [Next Page] to obtain desired shooting conditions. Is displayed, and shooting conditions are appropriately selected from the screen.
[0042]
The shooting condition selection screen 15 is created in consideration of the operability of the operator, and it is easy to select shooting conditions on the screen arranged in this way, but it is extracted from the manufacturer master data by the user. The type and number of shooting conditions you want to use are different, and there is a need to review the shooting conditions and screen configuration, such as differences in the frequency of use with continuous use and new shooting conditions. Sometimes it becomes.
[0043]
In this case, in the past, the manufacturer has performed the task of extracting the desired shooting conditions from the manufacturer master data and the operation of correcting the display order of the shooting conditions. In addition, the user can create a user-friendly screen as needed. However, as described above, the manufacturer master data includes hundreds of shooting conditions, and it is difficult to extract the shooting conditions required by the user, and an editing mechanism that supports editing work is provided. There was no image acquisition / display device or editing device provided.
[0044]
The background that makes it difficult to edit shooting conditions is the serial number assigned to each shooting condition in sequence, or even if a code that can be classified is assigned, the code configuration is It does not match the characteristics of radiological diagnosis and cannot be effectively searched or sorted. In this embodiment, therefore, various classifications can be made by assigning serial numbers composed of a plurality of classification codes set in consideration of the characteristics of radiological diagnosis to each imaging condition, and unfamiliar with machine operation. The above problem is solved by providing an editing screen that enables even a simple user to search and extract. The specific configuration will be described in each embodiment described later.
[0045]
Returning to the description of the shooting procedure, after selecting the shooting condition using the shooting condition selection screen 15, when the [OK] button is pressed, the identification label information (plate) read from the cassette 5 by the identification label detection unit 8f of the controller 8 is displayed. ID) is associated with shooting conditions and reading conditions. Then, the selected patient is photographed using a radiographic imaging apparatus such as the X-ray imaging apparatus 2, and the X-ray transmission image of the patient is recorded as a latent image on the radiographic image conversion panel 5 a inside the cassette 5.
[0046]
Next, an operator such as a radiologist takes out the cassette 5 from the X-ray imaging apparatus 2 and inserts the taken-out cassette 5 into an arbitrary slot of the reader 7. In the case of pre-registration, the reader 7 reads the plate ID, The database is searched using the ID as a search key, and the reading condition corresponding to the plate ID is extracted. In the case of post-registration, the reading condition corresponding to the cassette 5 is extracted from the association between the cassette insertion order queue and the reservation selection queue. Thereafter, the reader 7 reads the latent image of the radiation image conversion panel 5a in accordance with the set reading conditions.
[0047]
As a procedure for reading image data, first, according to the reading sensitivity and reading resolution set as reading conditions, the conveying speed of the plate conveying mechanism and the sampling pitch of the A / D converter 7d are set. Then, the radiation image conversion panel 5a is pulled out from the cassette 5, and the image data stored and held in the radiation image conversion panel 5a is read while the radiation image conversion panel 5a is scanned by the scanning mechanism.
[0048]
When excitation light acts on the radiation image conversion panel 5a, the energy accumulated in the phosphor is generated as stimulating light, and the stimulated light is collected and converted into an electrical signal by the photoelectric conversion unit 7c. The logarithmic converter converts the electric signal into a logarithmic converter (the electric signal is changed from an electric signal linear to the light intensity of the stimulating light to a logarithmic linear electric signal of the light intensity of the stimulating light, that is, linear to the concentration. The digital signal is further converted into a digital signal by the A / D converter 7d.
[0049]
The image data output from the A / D conversion unit 7d is subjected to correction processing (shading correction, unevenness correction caused by the excitation light generation unit, radiation correction) specific to the image acquisition display device 6 and the radiation image conversion panel 5a by the arithmetic processing unit 8b. (Sensitivity unevenness correction of the image conversion panel, etc.), gradation conversion processing, etc. are performed.
[0050]
Thereafter, a photographing routine screen as shown in FIGS. 9 to 11 is displayed. FIG. 9 shows a main display unit 16a on which representative image data is displayed, a sub-display unit 16b on which related captured image data is reduced and displayed in a thumbnail format, and a patient on which input patient information is displayed. FIG. 10 shows a shooting routine screen 16 in one image format provided with an information display area 16c and icons indicating modalities (standing position icon 16d, lying position icon 16e, and cassette icon 16f). In FIG. 11, a shooting routine screen 17 having a display format (collective format) in which four images are displayed on an equal scale is shown, and FIG. 11 is a shooting routine screen 18 having a display format in which two images are displayed on a comparable scale. From the above, a display format suitable for diagnosis is selected as appropriate, and the captured image data is displayed for diagnosis.
[0051]
Diagnosis is performed by repeating the above series of operations. However, medical imaging may be urgent, and in order to prevent mistakes in selecting imaging conditions, the imaging condition selection screen will be displayed according to the user's usage. Necessary and sufficient shooting conditions must be displayed. A shooting condition editing mechanism for allowing the user himself to extract shooting conditions from the maker master data and obtaining a desired shooting condition selection screen will be described below.
[0052]
[Example 1]
First, an image acquisition / display apparatus having an imaging condition editing mechanism according to a first embodiment of the present invention and an imaging condition editing method using the apparatus will be described with reference to FIGS. FIGS. 12 to 14 are diagrams showing examples of screen configurations displayed on the controller when shooting conditions are edited according to the present embodiment, and FIG. 15 is a diagram showing a configuration of classification codes assigned to shooting conditions. is there.
[0053]
As described above, there are a wide variety of shooting conditions, and it is necessary to cover all shooting conditions in the manufacturer master data set in advance by the manufacturer in order to meet the demands of each user. As a result, the shooting condition is divided into a large number of pages, and a desired shooting condition must be selected from the large number of pages, and the shooting condition selection operation takes time. To select shooting conditions smoothly, you can delete unnecessary shooting conditions and reduce the number of shooting conditions. However, it is up to you to decide which shooting conditions are required and which shooting conditions are unnecessary. For this purpose, it is preferable that the user himself creates user-specific master data.
[0054]
Therefore, in this embodiment, serial numbers composed of a plurality of classification codes set in consideration of the characteristics of radiological diagnosis are assigned to each imaging condition instead of serial numbers, and extraction, search, and arrangement using the classification codes are performed. Editing work such as replacement can be performed easily. More specifically, as shown in FIG. 15, a serial composed of a plurality of classification codes 22 such as a management flag 22a, a modality 22b, parts 22d and 22e, left and right 22f, an imaging technique 22g, an imaging direction 22h, and a branch number 22i. Number 23 is assigned to each imaging condition so that classification according to the characteristics of radiation diagnosis can be performed.
[0055]
Each of the classification codes 22 will be described. The management flag 22a includes a version of the master code itself, a flag for distinguishing between original and copy, and the modality 22b indicates a reading type such as standing, saddle, and cassette. Further, the part (1) 22c and the part (2) 22d are codes for classifying the respective imaging conditions for each part (head, chest, abdomen, neck, waist, spine, lung field, upper limb, lower limb, etc.). Yes, the left and right 22e represent types such as hand, foot, chin, left (L), and right (R). The imaging technique 22g is a code representing imaging methods such as simple / contrast / stress / bending / backbending, and the imaging direction 22h is AP, PA, front, side, RAO, LAO, RL, LR, etc. This is a code representing the shooting direction. Branch number 22i is a code representing a print format (1 × 1, 2 × 1, 1 × 2, etc.).
[0056]
That is, the conventional imaging conditions are numbered by serial numbers or classified and numbered for each part, so that extraction and search cannot be performed with detailed conditions, and the right and left, imaging technique, imaging direction, etc. Although it was difficult to retrieve the desired shooting conditions from a large amount of data because it was not possible to search with conditions specific to the shooting conditions, in this embodiment, various classifications can be made by finely classifying with the classification codes specific to the shooting conditions. Extraction and search are possible, and the convenience of the user is remarkably improved. Further, by providing a spare area in addition to the above classification code, it is possible to perform classification based on user-specific conditions, and it is possible to cope with new imaging conditions added in the future.
[0057]
The imaging condition classification code 22 is not limited to the above-described configuration, and may be any configuration that includes at least one classification code that represents characteristics specific to imaging conditions that reflect the characteristics of radiation diagnosis in addition to the imaging region.
[0058]
FIG. 12 shows a method for creating user-specific master data in which shooting conditions required by a user are extracted from master data provided by a manufacturer using shooting conditions to which a serial number composed of the classification code 22 is assigned. It demonstrates using the example of a screen structure of thru | or FIG.
[0059]
FIG. 12 is a screen configuration example of a master editing screen 19 that creates new user master data by extracting desired shooting conditions from original or user-created master data, and FIG. 13 is created on the master editing screen. FIG. 14 is a screen configuration example of the condition key editing screen 20 for confirming the contents and classification of the user master and editing the condition key. FIG. 14 shows a screen of the condition editing screen for displaying and editing the detailed contents of each photographing condition. It is a structural example.
[0060]
The photographing condition editing mechanism of this embodiment is composed of at least the above three types of screens. First, the master editing screen 19 will be described. This screen is referred to as shooting condition data (hereinafter referred to as user master data) extracted by the user from original shooting condition data provided by the manufacturer (hereinafter referred to as manufacturer master data). ), A copy source data display column 19a for displaying copy source maker master data or already created user master data, and a copy destination data display column 19b for displaying newly created user master data Each display field has a scroll function, an extraction function (extraction condition input field 19c), a search function (search button 19d), and a rearrangement function (rearrangement button 19e) for enabling display of desired shooting conditions. Is provided.
[0061]
For example, when extraction is performed from the maker master data on the condition of the head, the data of the value corresponding to the head (1) 22d of the classification code 22 is retrieved and displayed in the copy source data display column 19a. Is done. Here, in the configuration of the present embodiment, the imaging conditions are not limited to the imaging region (head / neck / chest / abdomen / spine / lumbar / upper limb / lower limb, etc.), but the modality 22b and the left and right 22f, shooting technique 22g, shooting direction 22h, branch number 22i, and the like, so that these conditions can be used as extraction conditions. For example, shooting conditions used for specific modalities or specific shooting It is possible to extract shooting conditions that meet the user's needs, such as shooting conditions for shooting with a technique, shooting conditions for shooting from a specific direction, shooting conditions for printing in a specific print format, etc., making it easy to select shooting conditions ing.
[0062]
When the sort button 19e is pressed, all data can be sorted in ascending order of serial number, serial number descending order, ascending order by part, and descending order by part. When the search button 19d is pressed, a search window is opened and the serial number is opened. You can search by name.
[0063]
The user displays the desired shooting conditions using the scroll function, extraction function, search function, and sort function, then clicks the mouse or moves the cursor to select the shooting conditions, and drag and drop the data. When moved, the selected shooting condition is displayed in the copy destination data display field 19b. When the simple selection button 19f is pressed, all data is specified, data of a specific part (head / neck / chest / abdomen / spine / lumbar / upper limb / lower limb, etc.) is specified. When the simple copy button 19g is pressed, the specified data can be copied at a time. This operation is repeated to extract a desired shooting condition.
[0064]
At that time, if there are a large number of copied data, it becomes difficult to know which shooting condition has been copied. Therefore, a predetermined condition is selected and extracted in the extraction condition input field 19c of the copy destination data display field 19b, or a sort button is selected. The photographing conditions selected by rearranging at 19e can be confirmed. When the copy button is pressed when editing is completed, the user master data is stored in the storage unit 8c.
[0065]
In this way, the copy source data display field 19a and the copy destination data display field 19b are displayed in comparison, and each is provided with a scroll function, an extraction function, a search function, and a rearrangement function, and can be edited by drag and drop. Thus, desired shooting conditions can be easily extracted from a large number of shooting conditions, and user-specific master data can be created.
[0066]
Further, it is possible to confirm and correct the detailed contents of each photographing condition displayed in the copy source data display field 19a and the copy destination data display field 19b. In that case, when the shooting conditions in each column are selected and clicked, a condition editing screen 21 as shown in FIG. 14 is displayed. The condition editing screen 21 includes, for example, an input condition field 21a and an output condition field 21b. The input condition field 21a includes the type of device that reads image data, sensitivity (low sensitivity / standard / high sensitivity), pixel Basic conditions such as size (standard / high definition), size (six-cut / four-cut / large-four / large-angle / half-cut), orientation (vertical / horizontal), position (top / middle / bottom / right / left), etc. An area for displaying a read pixel size and an image to be read is provided. In the output condition column 21b, the type of output destination printer, print format (1 frame 1 frame / 1 image 2 frames / 2 images 2 frames), output method (total output / cutout output), various image adjustments, Setting fields such as overlay display are provided. Then, the operator confirms the detailed setting of the photographing condition on the condition editing screen 21 or edits and returns to the master editing screen 19 to continue the editing work.
[0067]

As a result, only necessary and sufficient shooting conditions are displayed, making it easy to select shooting conditions.However, even if the number of shooting conditions is smaller than the manufacturer master data, it is not necessary to select shooting conditions by listing the data. take time. Some shooting conditions are used alone, while others are used as a set by combining a plurality of shooting conditions.
[0068]
For example, images that are normally shot are often taken and compared for even numbers such as front + side, right side + left side, right oblique, left oblique. In particular, two images are often taken as a set for the front and side of the chest, and when the lumbar spine is photographed from four directions (front, side, right oblique, left oblique), the density in the four directions is the same. In such a case, it is preferable to register the photographing condition as a set condition.
[0069]
Therefore, after the user master data is created, the user master data can be classified for each modality and each imaging region, or set conditions can be set using a condition key editing screen 20 as shown in FIG. The condition key edit screen 20 includes a master data display column 20a similar to the copy destination data display column 19b of the master edit screen 19, a modality classification column 20b for selecting a modality, and a head / neck / chest / abdomen / spine. A region classification column 20c for selecting an imaging region such as / lumbar region / upper limb / lower limb, and a condition display column 20d for displaying the imaging conditions of the selected classification are included.
[0070]
When the designated master data is displayed in the master data display field 20a and a condition corresponding to each classification code 22 is selected as the extraction condition, data matching the extraction condition is displayed, and the modality classification field 20b and the part classification field are displayed. When a desired category is selected from 20c, the shooting conditions corresponding to the category are displayed in the condition display column 20d with reference to the category code 22. The user confirms the contents displayed in the condition display field 20d, and if the classification automatically assigned by the classification code 22 is insufficient, the user can individually select the shooting condition and delete it from the classification, In addition, desired shooting conditions can be moved and registered from the master data display column 20a by drag and drop. Further, when a plurality of shooting conditions are selected in the master data display column 20a and moved to the condition display column 20d, the plurality of shooting conditions are registered in the classification as set conditions.
[0071]
The detailed contents of the individual shooting conditions can also be confirmed and edited on the condition key editing screen 20, and in this case, by clicking each shooting condition in the master data display column 20a or the condition display column 20d, The condition editing screen 21 thus displayed is displayed, and detailed contents can be confirmed and edited.
[0072]
Using the master editing screen 19, the condition key editing screen 20, and the condition editing screen 21 configured as described above, new user master data is created from maker master data or user master data that has already been created, When the conditions are registered, the shooting conditions classified by reflecting the contents are displayed in the classification display field 15b on the shooting condition selection screen 15, and the convenience of the user can be improved.
[0073]
As described above, in the imaging condition editing mechanism and the imaging condition editing method of the present embodiment, the imaging conditions are assigned serial numbers composed of a plurality of classification codes set in consideration of the characteristics of radiation diagnosis. Compared to conventional methods, more advanced and diverse extraction and retrieval can be performed. In addition, by using an editing screen as shown in FIGS. 12 to 14, even a user unfamiliar with the machine operation can extract a desired shooting condition from a large number of shooting conditions, correct a classification, A plurality of shooting conditions can be registered as set conditions.
[0074]
[Example 2]

For example, as shown in FIG. 16, the controller 8 includes a control unit 8a, an arithmetic processing unit 8b, a storage unit 8c, a display unit 8d, an operation unit 8e, an identification label detection unit 8f, an imaging condition editing unit 8g, and a screen creation unit 8h. In addition, the data arrangement unit 8i for rearranging the user master data with reference to the selection frequency of the shooting conditions is provided, and when the shooting condition selection screen 15 is created, the display order of the shooting conditions is changed according to the selection frequency. It can be updated as appropriate.
[0077]
In order to realize such rearrangement, for example, as shown in FIG. 17, a frequency area 22j for writing a numerical value corresponding to the selection frequency of each shooting condition in the spare column of the classification code 22 given to the shooting condition is provided. When the shooting condition is selected on the shooting condition selection screen 15, the storage unit 8c sequentially adds and stores the selection frequencies, and the arithmetic processing unit 8b sets the selection frequency or a value set in association with the selection frequency as the frequency. By writing in the area 22j, each photographing condition can be identified by the selection frequency. The time for the user to select the shooting condition can be shortened by displaying the shooting conditions that are selected almost frequently before the shooting conditions that are frequently selected according to the selection frequency.
[0078]
In addition, the date when the shooting condition is selected instead of the selection frequency can be stored in a predetermined area of the classification code 22, and the shooting condition can be displayed in the order of date. In addition, it is possible to display in front a part that is often taken urgently, or to display a part that covers a plurality of doctors, radiologists, and requested departments. Alternatively, the user may set a numerical value, and the display order may be set by referring to the numerical value when the photographing condition selection screen 15 is created.
[0079]
Such rearrangement of the display order can be automatically performed. In that case, according to the process of extracting the value of the predetermined classification code 22 from the serial number 23 of the shooting condition and the selection of the shooting condition on the shooting condition selection screen 15, the value of the classification code of the shooting condition is added. A shooting condition array program that performs a process of ranking a plurality of shooting conditions with reference to the value of the classification code, and a process of setting a display position based on the rank, and is executed. Is possible.
[0080]
In this way, taking advantage of the characteristics of serial numbers composed of multiple classification codes, the selection frequency, shooting date, etc. are recorded and written in the classification code, and the display order of the shooting conditions is determined in consideration of the classification code value. By automatically updating, it is possible to always display a screen that is easy to handle, and it is possible to smoothly perform a medical diagnosis by reducing the time required for the user to select imaging conditions.
[0081]
In each of the above embodiments, the editing of the shooting conditions has been described. However, the present invention is not limited to each of the above embodiments, and new data is extracted by extracting data suitable for the user's usage form from an arbitrary data string. The present invention can be applied to an editing mechanism, an editing method, and an editing apparatus that generate a simple data string.
[0082]
【The invention's effect】
