As shown in Figure 1, the radiation treatment image generation system 100 according to an embodiment of the present invention, first related to the medical image information taken from the medical imaging apparatus for the radiation treatment, and the radiation treatment plan of the patient It receives and interprets radiation treatment data information including data.

The analysis information is disposed in a three-dimensional space, converted into a three-dimensional form, and a three-dimensional image is generated by integrating the medical image information and the radiation treatment data information converted into the three-dimensional form.

And at least one selected from a method of cutting the three-dimensional image into an arbitrary plane, a method of projecting the three-dimensional image into an arbitrary plane, a method of visualizing the three-dimensional image from an arbitrary viewpoint, and a method of curved in a graph form. In one method, a radiotherapy image is generated and output to the outside.

The medical image information may include at least one of a CT (Computed Tommography) device, a Magnetic Resonance Imaging (MRI) device, a Positron Emission Tomography (PET) device, a CT scanner, and a Computed Radiography (CR) device. It is taken from the medical imaging device of the digital imaging and communication standards (DICOM: Digital Imaging and Communications in Medicine) in the form of a DICOM image file is input to the radiation therapy image generation system 100.

The medical digital image communication standard (DICOM) is a standard communication standard for exchanging image related information from imaging equipment of various manufacturers, and is adopted by many global medical imaging device manufacturers.

The radiation treatment data information is generated in a radiation treatment planning system (RTP), which is a device for programmatically establishing (creating) a radiation treatment plan of a patient, and is DICOM RT (Radiotherapy) according to the medical digital image communication standard (DICOM). It is input to the radiation therapy image generation system 100 in the form of a data file.

The process of radiotherapy planning in the radiotherapy planning system (RTP) can be simplified as follows.

In other words, the Volume Contour process, which is the process of drawing important organs and treatment areas in the treatment plan of the patient while looking at the medical image, and the point to be noted in the treatment or the center of the beam. Point setup process to designate important points, beam setup process to add beams and direction of each beam, and calculate radiation dose to patient in three dimensions ( This is done by a separate calculation engine of the program). It includes the Dose Calculation & Evaluation process which reviews this and determines the final treatment.

The radiation treatment plan established by the above process is provided as the radiation treatment data information, and is generally provided in three file types. For example, it is provided in the form of RT Structure Set file, RT Plan file, RT Dose file.

In the RT Structure Set file, point information and important organs that designate a point to be noted for treatment or a center of the radiation beam among the radiation treatment plan information created in the radiation treatment planning system (RTP) And volume information indicating the treatment area is stored.

The RT plan file stores treatment information including beam-related information among the radiation treatment plan information.

The RT Dose file contains radiation dose information that is expected to be absorbed into the patient's body due to the radiation treatment plan.

The radiation therapy image generation system 100 includes at least one medical device including a computed tommography (CT) device, a magnetic resonance imaging (MRI) device, a positron emission tomography (PET) device, and a computed tomography simulator (CT Simulator). When connected to an imaging device or a medical image storage transmission system (PACS) through a network (for example, a DICOM network), the medical image information is provided using a protocol defined for medical image image communication. However, if there is no network connection or needs arise, it can be provided through local file system including magnetic disk, optical disk drive, flash drive and network drive.

The same is true for the radiation treatment data information. That is, when the radiation treatment image generation system 100 is connected to the radiation treatment planning system (RTP) or the like through a network (for example, a DICOM network), the medical image information may be obtained by using a protocol defined in medical image image communication. You will be provided. However, if there is no network connection or needs arise, it can be provided through local file system including magnetic disk, optical disk drive, flash drive and network drive.

Hereinafter, a detailed configuration of the radiation treatment image generation system 100 will be described with reference to FIG. 2.

FIG. 2 is a block diagram illustrating an internal configuration of the radiation therapy image generating system of FIG. 1.

As shown in FIG. 2, the radiation therapy image generating system 100 includes an image and data acquisition module 110, an RT data analysis module 130, a shape generation module 140, and a three-dimensional reconstruction module 120. , A dose evaluation module 150, an image generation module 160, and an image output and transmission module 170.

The image and data acquisition module 110 internally classifies and stores information provided from the outside into the medical image information and the radiation treatment data information.

In general, the medical image information and the radiation treatment data information are input without mixing in the form of DICOM files. Therefore, it is necessary to classify the mixed DICOM files into the medical image information in the form of DICOM image files and the radiation therapy data information in the form of DICOM RT data files. This operation is performed by the image and data acquisition module 110.

The DICOM image file includes files for images used in the radiotherapy plan according to the position in the vertical direction of the image (viewed from the patient's head to the foot). For example, in order to make a treatment plan on the patient's head, cross-sectional images can be obtained at 0.5 cm intervals starting from the patient's head.

The DICOM RT data file is divided into three types, RT structure set file, RT plan file, and RT dose file. These three files contain volume information, point information, beam information, and dose information.

The RT data analysis module 130 interprets the radiation treatment data information provided in the image and data acquisition module 110 (eg, an RT structure set file, an RT plan file, and an RT Dose file), and thus the volume. The data is classified into volume information, the point information, the beam information, and the dose information and stored.

The information classified by the image and data acquisition module 110 is medical image information and radiation treatment data information as described above. The medical image information may be three-dimensional reconstruction process immediately, while the radiation treatment data information may correspond to each volume information, point information, beam information, dose ( Dose) It is necessary to interpret each information.

Here, the volume information refers to information indicating important organs and treatment sites. The point information refers to information designating a point to be treated or a center of a radiation beam, and the beam information. Refers to information about the beam addition direction or the irradiation direction of the beam, and the dose information includes information for calculating a dose to be received by the patient (absorbed in the body).

Volume information, point information, beam information, and dose information analyzed by the RT data analysis module 130 may include information values for various items according to each data structure. Can be.

In the case of the volume information, for each volume, the name of the volume in the form of text, the color represented by the RGB scale, and the form according to the position in each vertical direction (the treatment area is determined by the radiation treatment plan. Contour information, etc.). In the case of the point information, each point includes a name of a point, a color expressed in an RGB scale, and position information which is a position of a point in a three-dimensional space.

In addition, in the case of beam information, for each beam, beam center information (beam center information) indicating a beam center having a beam name, a point location in a three-dimensional space, and a plurality of angles (Gantry, Table). , Angle information of the beam determined by a collimator). In this case, information on parameters such as beam energy, field size, Wedge, MLC, Block, and Bolus may be added to the beam information.

Finally, in the case of dose information, a certain range of three-dimensional space for a single data file (usually, it is limited to a specific rectangular parallelepiped space in three dimensions, and for this purpose, X, Y, and Z in three directions: Information on the radiation dose for all points within the range).

The shape generation module 140 stores the volume information, the point information, the beam information, and the dose information stored in a data form in the RT data analysis module in a three-dimensional space. Place it on to convert it into a three-dimensional form.

Volume information, point information, beam information, and dose information stored in the RT data analysis module 130 exist only as data but do not form a form in three dimensions. Accordingly, the shape generation module 140 converts such data into a three-dimensional form by a predetermined rule for each information.

First, in the case of point information, as shown in FIG. 3, the point information is converted into a three-dimensional form based on the position information and the color, which are the positions of the points on the three-dimensional point of the point information.

In the case of the volume information, the volume information is arranged in a three-dimensional space based on the volume information. In particular, since the contour information has the shape of a polygon according to each vertical position, it is a three-dimensional method by creating complete three-dimensional data using interpolation and arranging it in a three-dimensional space as shown in FIG. Convert to form

In the case of the beam information, as shown in FIG. 5, the beam center information and the angle information of the beam are not three-dimensionally disposed in the three-dimensional space as in the case of the point information or the volume information. It is made into a horn shape and placed in a three-dimensional space and converted into a three-dimensional shape.

In the case of the dose information, a constant dose (eg, at 10% intervals (10%, 20%, 30%, ..., 100%) based on the maximum radiation dose in the three-dimensional space) Iso-dose surfaces) are made as shown in FIG. 6, and each surface is placed in three-dimensional space and converted into a three-dimensional form. The iso-dose surface is a concept similar to the iso-dose line defined in three dimensions and defined in two dimensions. Iso-Dose Line is a line that is subsequently plotted with points that have the same dose value (for example, 80% of the maximum dose) on a plane. It is the plane connecting the points with dose values.

The 3D reconstruction module 120 arranges the medical image information provided by the image and data acquisition module 110 in a 3D space, converts the medical image information into a 3D form, and is provided by the shape generation module 140. The volume information, the point information, the beam information, and the dose information in a three-dimensional form are integrated with the medical image information in a three-dimensional form to provide a medical image, a volume, Point, beam, and dose forms three-dimensional images (3D volume data), each consisting of independent layers.

The medical image information is provided in the form of a DICOM image file in the image and data acquisition module 110, and the DICOM image has respective image data according to each vertical position. For example, the vertical direction is usually represented by 'Z', and image data such as an image of Z = -14.00 cm, an image of Z = 0.5 cm, and the like exist. here, Z = 0.5cm or Z = -14cm is an indication of how far the image is from the reference point. When taking a CT image, the image is taken from the head of the patient and ends in the direction of the foot, and vice versa. Since it depends on which part is taken as a reference point, various interpretations are possible in some cases.

The three-dimensional reconstruction module 120 arranges the above-described medical image information in a three-dimensional space and converts the medical image information into a complete three-dimensional image while supplementing an intermediate part with interpolation.

The three-dimensional form of the medical image information obtained as described above is the volume information, the point information, the beam information, and the dose of the three-dimensional form provided by the form generating module 140. By integrating with dose information, a 3D volume data is generated in which medical image, volume, point, beam, and dose forms are each composed of independent layers.

Here, integrating the three-dimensional form of medical image information with the volume information, the point information, the beam information, and the dose information means to virtually group these data together. Meaning that it is composed of independent layers means that the three-dimensional form of the medical image information, the volume information, the point information, the beam information, and the dose information are integrated. However, it means that it is configured to be separated into individual object information again. As a simple example, when we express colors, we use RGB (Red-Green-Blue), but if there is an image file, each RGB data is not stored separately but is integrated and stored in one image file. That's the same thing you can get for each point in RGB.

The dose evaluation module 150 uses the volume information and the dose information provided by the RT data analysis module 130 to determine the distribution of dose in each volume as a whole maximum radiation dose. The graph data is generated in the form of a Dose-Volume Histogram (DVH) graph by statistic by the ratio of and the distribution of each ratio.

In other words, the distribution of dose in each volume is statistically calculated for the ratio (1% interval: 0%, 1%, ..., 100%) to the total maximum radiation dose to find the distribution number for each ratio and graph You will generate DVH graph data that is a curve.

The image generation module 160 may include a cut image, a projection image, a 3D rendering image, and the 3D image through the 3D volume data provided by the 3D reconstruction module 120. The radiation treatment image (image array) is generated and stored by generating a graph image through the graph data provided from the dose evaluation module 150.

The image generation module 160 may generate a radiotherapy image by appropriately selecting a cut image, a projection image, a 3D rendering image, and a graph image as needed. It is also possible to create them simultaneously.

As shown in FIG. 7, the cut image is generated by cutting the 3D volume data into an arbitrary plane. As shown in FIG. 8, the projection image is generated by projecting the 3D volume data onto an arbitrary plane.

As shown in FIG. 9, the rendered image is generated by visualizing the 3D volume data through a rendering process based on an arbitrary viewpoint or an arbitrary direction.

The rendering process refers to representing a three-dimensional structure as a two-dimensional image. A similar concept, for example, is that when we take a picture with a camera, the space we are in is a three-dimensional space. What is obtained is the same as being a two-dimensional image. The rendering process refers to a process of obtaining a 2D image from 3D in this manner. At this time, the image displayed by the rendering is determined by the viewpoint and the direction, and the image obtained by the camera is the same as it depends on where it is taken and which direction is taken based on a specific point of view.

The graph image is generated in the form of a DVH image by imaging the graph data provided from the dose evaluation module 150, as shown in FIG.

The image output and transmission module 170 is an image file format including a bitmap and JPEG or an image of a medical digital image communication standard (DICOM) of the radiation treatment image (image array) generated by the image generation module 170 It is converted to file format and sent to the outside.

When the image output and transmission module 170 is connected to a medical image storage transmission system (PACS) or the like in a hospital (for example, a DICOM network), the radiotherapy image using a protocol defined for medical image image communication. (image array) will be sent to the outside. However, if there is no network connection or needs arise, it can be provided through local file system including magnetic disk, optical disk drive, flash drive, network drive.

In this case, the image output and transmission module 170 converts the radiotherapy image into a bitmap or JPEG image file format and transmits the medical treatment image when transmitting to a local file system including a magnetic disk, a flash drive, and a network drive. In case of transmitting by protocol defined in communication, it can be converted into DICOM SC (Secondary Captured) image file and transmitted.

As described above, according to the present invention, by generating and providing a radiation treatment image containing radiation treatment information, the radiation treatment information can be easily known along with the image, and the treatment of the patient with the treatment record when the treatment information is inquired. Because you can check the important image together, there is an advantage to make the most of the information.

The foregoing description of the embodiments is merely illustrative of the present invention with reference to the drawings for a more thorough understanding of the present invention, and thus should not be construed as limiting the present invention. It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the basic principles of the present invention.
