Embodiment Construction

[0019] refer to figure 1 A treatment system 10, such as an intensity modulated radiation therapy (IMRT) system or a volume modulated arc therapy (VMAT) system, includes an imaging system 12 to generate one or more planning images of a region of interest of a patient. The image volume (ie, the planning image) is volumetric (ie, three-dimensional) and is typically stored in the planning image memory 14 of the treatment system 10 . A region of interest includes one or more target structures, and typically includes one or more critical structures or organs at risk (OARs). Each of the target structures is a lesion or other tissue region, such as a tumor, to be irradiated. Each of the critical structures is an area of ​​an organ or other tissue at risk of damage from radiation intended for the target structure, such as radiation traveling to the target structure, which radiation has passed through the target structure, or which has passed through the target structure in close proxi...

Abstract

An automated treatment planning system having a planning image memory which stores a volume diagnostic image; a user interface device configured for a user to input data defining a plurality of regions of interest within the volume diagnostic image; and one or more processors. The processors are configured to receive the volume diagnostic image and plurality of user-defined regions of interest indicated within the volume diagnostic image; map the plurality of regions of interest to the body atlas to determine anatomical locations within the plurality of regions of interest; map each region of interest of the plurality of regions of interest to the body atlas to select correct corresponding anatomical structures; receive a treatment plan template based upon the anatomical structures from a knowledge base. A planning module is configured to generate a treatment plan using the treatment plan template.

Description

technical field [0001] This application relates generally to radiation therapy. This application finds particular application in connection with radiation therapy planning and will be described with particular reference thereto. However, it should be understood that the present application is also applicable to other usage scenarios and is not necessarily limited to the above-mentioned applications. Background technique [0002] In radiation therapy planning, creating a patient-specific treatment plan can be a time-consuming and tedious task. Some of the steps are redundant and vary little between different patients or different plans. Some of these steps can be automated using macro languages ​​or scripts, but some aspects are difficult without tools for writing logical expressions, loops, and other common programming functions. [0003] Over the past decade, technological advances have provided great leaps in the fields of intensity modulated radiation therapy (IMRT), i...
