Abstract: In an implementation, a system for registering at least one medical image is provided, the system including a standardization component that may initially adjust the medical image. The system provides a deep learning model that receives the at least one medical image from the standardization component, the deep learning model generating an 3D transform matrix for the at least one medical image relative to a template image based on trained machine learning logic and an interpolation component that receives the 3D transform matrix from the deep learning model and receives the at least one medical image, the interpolation component registering the at least one medical image in three-dimensional space based on the 3D transform matrix.

Abstract: The present invention discloses a PET system attenuation correction method based on a flow model. The flow model adopted is a completely reversible model, the forward and reverse mappings share the same parameters, and the structure itself is a consistency constraint. The model utilizes the spatial correlation of adjacent slices, and adopts the structure of multi-slice input and single-slice output. The model consists of multiple reversible blocks, each of which consists of a enhanced affine coupling layer and a reversible 1×1 convolutional layer, and uses several small u-nets to learn the transformation parameters of the enhanced affine coupling layer. The present invention avoids additional CT or MR scanning, saves scanning cost for the patient, and reduces the damage of CT radiation to the patient; compared with similar methods, higher quality non-attenuation-corrected PET image can be obtained.

Abstract: In various examples, a two-dimensional (2D) and three-dimensional (3D) deep neural network (DNN) is implemented to fuse 2D and 3D object detection results for classifying objects. For example, regions of interest (ROIs) and/or bounding shapes corresponding thereto may be determined using one or more region proposal networks (RPNs)—such as an image-based RPN and/or a depth-based RPN. Each ROI may be extended into a frustum in 3D world-space, and a point cloud may be filtered to include only points from within the frustum. The remaining points may be voxelated to generate a volume in 3D world space, and the volume may be applied to a 3D DNN to generate one or more vectors. The one or more vectors, in addition to one or more additional vectors generated using a 2D DNN processing image data, may be applied to a classifier network to generate a classification for an object.

Abstract: The disclosed method relates to an approach of monitoring validity of a patient registration, wherein a contour of a rigid anatomical structure is initially determined in three-dimensional space, and its spatial position is constantly checked afterwards so as to detect a possible spatial deviation of the contour which may indicate an invalidated patient registration.

Abstract: A framework for registering anatomical to functional images using deep learning. In accordance with one aspect, the framework extracts features by applying an anatomical image and a corresponding functional image as input to a first trained convolutional neural network. A deformation field is estimated by applying the extracted features as input to a second trained convolutional neural network. The deformation field may then be applied to the anatomical image to generate a registered anatomical image.

Abstract: An improved method and system for image alignment of an inspection image are disclosed. An improved method comprises acquiring an inspection image, acquiring a reference image corresponding to the inspection image, acquiring a target alignment between the inspection image and the reference image based on characteristics of the inspection image and the reference image, estimating an alignment parameter based on the target alignment, and applying the alignment parameter to a subsequent inspection image.

Abstract: A method performed by a computing system comprises receiving shape information for an elongate flexible portion of a medical instrument. The medical instrument includes a reference portion movably coupled to a fixture having a known pose in a surgical reference frame. The fixture includes a constraint structure having a known constraint structure location in the surgical reference frame. The elongate flexible portion is coupled to the reference portion and is sized to pass through the constraint structure. The method further includes receiving reference portion position information in the surgical reference frame; determining an estimated constraint structure location in the surgical reference frame from the reference portion position information and the shape information; determining a correction factor by comparing the estimated constraint structure location to the known constraint structure location; and modifying the shape information based upon the correction factor.
