DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, without any other intention than to provide a thorough understanding of the present invention to those skilled in the art.

1 is a block diagram of a radiation treatment planning system according to an embodiment of the present invention.

As shown in FIG. 1, a radiation treatment planning system according to an embodiment of the present invention includes an auxiliary radiation treatment planning system group 150 (hereinafter, referred to as 'secondary') having at least one auxiliary radiation treatment planning system 152, 154, and 156. sub) RTP ') and a main radiation treatment planning system group 400 (hereinafter referred to as' main RTP') having at least one main radiation treatment planning system.

The main RTP 400 performs contouring, radiotherapy planning, radiation dose calculation and review for organs such as organs or radiation treatment targets of a patient. The radiation treatment plan information established in the main RTP 400 will be referred to as main treatment plan information.

The auxiliary RTP 150 is contouring for setting an organ or a radiation treatment target such as an organ of a patient, a radiation treatment plan created by the main RTP 400, and a calculated radiation dose distribution. Query and so on. In addition, modification or change of the radiotherapy plan created in the main RTP 400, and simple dose calculation and review of the changed treatment plan is performed. In addition, when the main RTP 400 is composed of a plurality of main RTP, the secondary RTP 150 integrates and manages treatment plan information in each main RTP 400. In order to assist the main RTP 400 in the auxiliary RTP 150, supplementary treatment plan including contouring and / or beam parameters generated based on patient information and medical images of the patient. It will be referred to as information.

The relationship between the secondary RTP 150 and the main RTP 400 will be described in more detail as follows.

Contouring is generally performed in the secondary RTP 150, and the main RTP 400 performs radiotherapy planning and dose calculation accordingly. However, when there is room in the main RTP 400, the contouring may be performed. In addition, the final treatment plan, dose calculation and review are performed in the main RTP (400).

The contouring process is the most time-consuming task in the preparation of the overall treatment plan information, so if you do this in the secondary RTP 150, the secondary RTP 150 does what the original RTP 400 should do. During that time, other important tasks can be performed in the main RTP 400, which can increase the efficiency of the work in the radiation treatment plan.

In addition, after establishing treatment plan information of a patient in the main RTP 400 and calculating a dose, the secondary RTP 150 may query detailed treatment plan information and dose distribution of the treatment plan information for the patient.

The detailed treatment plan information may include any information (eg, contour information, beam parameter information, etc.) within a range supported by the main RTP 400 required for radiotherapy. .

When there is a method that may be better with respect to the treatment plan information, the treatment plan information such as the change of the beam parameter may be modified and changed. And if the result is better after simple dose calculation and review of the changed treatment plan information, the modified treatment plan information may be established as the final treatment plan.

In addition, some radiation therapy devices may rely on a specific radiotherapy planning system (RTP). Thus, for some radiotherapy devices, the transmission of treatment planning information is only possible using the functionality of a specific radiotherapy planning system (RTP). Therefore, when the number of radiotherapy devices introduced in one hospital is large, the number of main RTP 400 should also be increased. In this case, it becomes difficult to manage the treatment plan information and dose distribution established in each main RTP 400. However, in the case of using the secondary RTP 150, if the treatment plan information is transmitted from the main RTP 400 to the secondary RTP 150, since the secondary RTP 150 can be integrated and managed, each treatment plan information Management is very easy.

When the secondary RTP 150 is composed of a plurality of secondary RTPs 152, 154, and 156, some secondary RTPs (eg, 152) perform the contouring process and some secondary RTPs (eg, 154). ) May perform treatment plan information and dose distribution query, and some secondary RTPs (eg, 156) may perform modifications or changes of the treatment plan information.

 Since the secondary RTP 150 performs only a role for assisting the main RTP 400, the secondary RTP 150 may include a program or other device for performing such a role.

In addition, the main RTP 400 may be a general radiotherapy planning system (RTP) well known to those skilled in the art.

The data or information of the main RTP 400 and the secondary RTP 150 may be a digital imaging and communications in medicine (DICOM) (eg, Images, RT Structure Set, RT Plan, RT Dose). Can be made through communication. Currently, most radiation treatment planning systems in the main RTP class support this.

First, when an image of a medical image photographed by medical imaging apparatuses is loaded to establish a radiation treatment plan, as shown in the screen of FIG. 6, the organ of the patient or the target of cancer treatment is not set. It is a state. Setting such an organ or target is referred to as a region of interest (ROI) or a volume of interest (VOI), which is expressed as a set of lung curves. If no ROI is set, it is not possible to grasp the effects of radiation doses to organs or targets such as organs after calculating the dose, so it is necessary to draw each ROI before planning treatment. In other words, contouring is performed.

 In the treatment plan preparation, important organs or cancer treatment sites of the patient are registered and then drawn directly as shown in the screens of FIGS. 7 and 8. Most RTPs offer improved contouring, which is often done automatically or semi-automatically rather than manually.

After each ROI contour is completed for each image slice, a treatment plan can be developed. That is, it is possible to prepare main treatment plan information. 9 is a three-dimensional image screen after contouring (contouring), it can be seen that each ROI is a contour (Contour).

This may be done in the secondary RTP 150 according to one embodiment of the invention.

10 and 11 are 2D and 3D image screens in which the final treatment plan information is prepared.

As shown in FIG. 10, cancer tissues receive radiation in a two-dimensional manner in the center of the screen, and the color distribution is such that each part of the body receives energy from three X-ray beams. Is indicated. The table at the bottom of the screen displays detailed information about the three X-ray beams, and the numbers in this table represent treatment plan information.

As shown in FIG. 11, the energy distribution received by X-rays is displayed in three dimensions, and the contour (VOI) specifying each organ is also displayed in a wire frame. It is. For example, yellow denotes the outline of the body, light blue denotes the eyeball, and blue denotes the optic nerve. On the left side of the screen, the VOI specifying each organ representing the composition of the final treatment plan, the POI including location information, and three beams used in the treatment are shown.
