Problems solved by technology

However, one problem with this approach is that the user has much more flexibility than needed, which makes the workflow too general and not focused on the physician
Another problem is that it only has impact-based programs exclusively

Embodiment Construction

[0022] refer to figure 1 A treatment system 10 (eg, an intensity modulated radiation therapy (IMRT) system or a volume modulated arc therapy (VMAT) system) includes an imaging system 12 for generating 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 target structure is a lesion or other tissue region, such as a tumor, to be irradiated. Each critical structure is an organ or other tissue region at risk of being damaged by radiation intended for the target structure (e.g., radiation that travels to the target structure), the radiation passes through the target structure, or the radiation is in close proximity to the target structure through.

Abstract

A planning image memory (14) stores volumetric diagnostic images. A user enters data defining clinical objectives including organs at risk using a user interface device (32). An automated planning module (36) generates candidate treatment plans. A tradeoff module (38) has a processor that evaluates the treatment plan against the clinical goal. When one or more goals are not met, the trade-off module (38) performs a trade-off analysis to determine effects on other clinical goals and generates at least one trade-off treatment plan that more closely meets the unmet goals. A candidate plan and at least one trade-off plan are displayed on a display device (30) and / or analyzed by said processor, and a final treatment plan is selected from said at least one trade-off treatment plan and said candidate treatment plan.

Description

technical field [0001] This application relates generally to radiation therapy. This application is described in conjunction with, and with specific reference to, the specific application of radiation therapy planning. However, it is to be understood that the present application is also applicable to other use cases and is not necessarily limited to the aforementioned applications. Background technique [0002] In radiation therapy planning, creating a patient-specific treatment plan can be a time-consuming and tedious task. Many steps are redundant and vary very little between different patients or between different plans. Many 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 giant leaps in the fields of intensity-modulated radiation therapy (IMRT), intensity-mod...
