CN-122003206-A - Method and system for automatic X-ray imaging system orientation using image features

Abstract

A method for predicting an optimal orientation of an imaging device. The method includes obtaining an initial image of an anatomy, extracting at least one image feature of the anatomy from the initial image, and predicting an optimal orientation of one or more adjustable components of the imaging device for subsequent imaging of the anatomy based on the extracted at least one image feature. The predicting of the optimal orientation may include at least one of (i) maximizing an alignment of an imaging system with the anatomy, (ii) minimizing an area around the anatomy to be excluded from X-ray imaging, (iii) maximizing an alignment of the imaging device to collimate out a portion of the anatomy to be excluded from subsequent imaging, and (iv) maximizing an amount of the anatomy to be included in the subsequent imaging.

Description

Method and system for automatic X-ray imaging system orientation using image features Technical Field The present disclosure relates generally to methods and systems for predicting an optimal orientation of one or more adjustable components of an imaging system. Background A physician or technician typically needs to make several adjustments to the X-ray imaging system in order to capture the desired field of view (FOV) in the image. These adjustments may include both out-of-plane rotation of the X-ray imaging system and in-plane rotation of the X-ray imaging system. As just one example, when radial access is obtained, the patient's arm is at aboutIs extended away from the body and imaging the radial artery up to the shoulder requires that the imaging system also be rotated to accommodate the rotation of the arm. The rotation may be a specific combination of rotation of the L-arm, rotation of the detector, etc. The combination of rotations balances the various needs of the user, including the ability to align the imaging system with the anatomy to be imaged while maintaining the collimation out of areas not requiring imaging (e.g., air around the arm), or while maximizing the amount of anatomy to be imaged that is included in the FOV (such that, for example, only one contrast injection is needed to navigate through the arm and shoulder). These various evaluations are not always intuitive, can be difficult and time consuming to perform, and can result in under-utilization of system capabilities (e.g., under-utilization of detector rotation or under-utilization of collimation), sub-optimal image acquisition (e.g., a smaller FOV than desired for a second acquisition requiring a different FOV), additional use of contrast agent (e.g., two DSAs with a smaller field of view, rather than one DSA with a larger FOV), and so forth. These evaluations may be further complicated in imaging systems where the sources may also be rotated independently (e.g., philips [ Azurion ] FlexArm, C X-free radiographic imaging systems, etc.). Disclosure of Invention Accordingly, there is a continuing unmet need for methods and systems for effectively and accurately automatically adjusting the orientation of an imaging device (e.g., an X-ray imaging device) in order to optimally align the device with the anatomy to be imaged. The imaging apparatus is also referred to herein as an "imaging system" (e.g., an "X-ray imaging system" or an "X-ray system"). Various embodiments and implementations relate to a method and system for predicting an optimal orientation of one or more adjustable components of an imaging device using an orientation system. The methods and systems described or otherwise contemplated herein generally relate to in-plane rotation of an imaging/orientation system. According to one aspect, a system is provided that is configured to obtain an initial image of an anatomy and extract at least one image feature of the anatomy from the initial image. The system is configured to predict an optimal orientation of one or more adjustable components of the imaging device for subsequent imaging of the anatomy based on the extracted at least one image feature. In some embodiments, one or more adjustable components of the system may then be automatically or manually oriented to the predicted optimal orientation. According to one aspect, a method for predicting an optimal orientation of an imaging device is provided. The method includes obtaining an initial image of an anatomy, extracting at least one image feature of the anatomy from the initial image, and predicting an optimal orientation of one or more adjustable components of the imaging device for subsequent imaging of the anatomy based on the extracted at least one image feature. According to an embodiment, the method comprises applying a trained imaging orientation model configured to analyze the extracted at least one image feature to predict an optimal orientation of the one or more adjustable components. According to an embodiment, the method further comprises obtaining information comprising an identification of an anatomy to be imaged by the imaging device, and analyzing the information to predict an optimal orientation of the one or more components. According to an embodiment, the method further comprises receiving approval from a user via a user interface to orient the one or more adjustable components to the predicted optimal orientation, and orienting, by the imaging device, the one or more adjustable components to the predicted optimal orientation. According to an embodiment, the received approval includes a fine adjustment of the predicted best orientation from the user, and the orienting includes orienting the one or more adjustable components to the fine-adjusted predicted best orientation. According to an embodiment, the predicting of the optimal orientation of the one or more adjustable components includes at least one of (i) maximizing an alignment of the imaging
