Embodiment Construction

[0019] refer to figure 1 , a radiation therapy system 100 for a user treating a patient is provided. The radiation therapy system 100 includes one or more imaging modalities 102 adapted to acquire images representing objects of interest (OOIs) in the patient, such as regions of interest (ROIs) and points of interest (POIs). Imaging modality 102 suitably includes a computed tomography (CT) scanner. However, the imaging modality 102 may additionally or alternatively include positron emission tomography (PET) scanners, magnetic resonance (MR) scanners, single photon emission computed tomography (SPECT) scanners, etc. one or more.

[0020] Images acquired from imaging modality 102 are typically three-dimensional images. However, a 2D image is expected. A three-dimensional image typically comprises a plurality of two-dimensional images, hereinafter referred to as slices. Additionally, images acquired from imaging modality 102 are stored in image memory 104 . Typically, image ...

Abstract

A system (106) visualizing an image registration mapping in an intuitive interactive manner. The system (106) includes a display (110) and one or more processors (116). The processors (116) are programmed to receive a first image and a second image and obtain an image registration mapping from the first image to the second image. Even more, the processors (116) are programmed to display the first image adjacent to the second image on the display (110) and obtain one or more reference image locations. Each of the reference image locations is defined in the coordinate frame of one of the first image and the second image. Moreover, the processors (116) are programmed to highlight each of the reference image locations on the one of the first image and the second image and highlight a correlated image location for each of the reference image locations in the other one of the first image and the second image. The correlated image locations are determined using the image registration mapping.

Description

technical field [0001] This application generally relates to image registration. It is particularly suitable for use in conjunction with radiation therapy and will be described with particular reference to radiation therapy. However, it should be understood that the present application is also applicable to other usage scenarios and is not necessarily limited to the aforementioned applications. For example, the present application is suitable for visually analyzing image registration maps in certain image studies, in monitoring the progress of a treatment regimen or the progress of a medical condition, in planning a treatment course, and the like. Background technique [0002] In radiation therapy, a spatially targeted dose of radiation is applied to a tumor or other area containing cancerous or malignant tissue. Growing and rapidly replicating cancer cells tend to be more susceptible to radiation damage than normal cells, so that doses administered through rational planni...
