Simulation method and system for an optimized implant site
The invention describes a computer-implemented method and an optimized implant site simulation system which performs a simulation of a damaged oral cavity of a patient and defines an implant site adapted to receive a dental implant to repair the damage observed. The invention further describes the optimized implant site simulated (SI) and a dental implant (ID) couplable to the optimized implant site (SI) simulated. The invention further describes a computer program to perform the steps of the method and an optimized implant site (SI) simulation system.
Generating approximations of cardiograms from different source configurations
Systems are provided for generating data representing electromagnetic states of a heart for medical, scientific, research, and/or engineering purposes. The systems generate the data based on source configurations such as dimensions of, and scar or fibrosis or pro-arrhythmic substrate location within, a heart and a computational model of the electromagnetic output of the heart. The systems may dynamically generate the source configurations to provide representative source configurations that may be found in a population. For each source configuration of the electromagnetic source, the systems run a simulation of the functioning of the heart to generate modeled electromagnetic output (e.g., an electromagnetic mesh for each simulation step with a voltage at each point of the electromagnetic mesh) for that source configuration. The systems may generate a cardiogram for each source configuration from the modeled electromagnetic output of that source configuration for use in predicting the source location of an arrhythmia.
Systems and methods for numerically evaluating vasculature
Systems and methods are disclosed for providing a cardiovascular score for a patient. A method includes receiving, using at least one computer system, patient-specific data regarding a geometry of multiple coronary arteries of the patient; and creating, using at least one computer system, a three-dimensional model representing at least portions of the multiple coronary arteries based on the patient-specific data. The method also includes evaluating, using at least one computer system, multiple characteristics of at least some of the coronary arteries represented by the model; and generating, using at least one computer system, the cardiovascular score based on the evaluation of the multiple characteristics. Another method includes generating the cardiovascular score based on evaluated multiple characteristics for portions of the coronary arteries having fractional flow reserve values of at least a predetermined threshold value.
Systems and methods for scanning a patient in an imaging system
The present disclosure relates to systems and methods for scanning a patient in an imaging system. The imaging system may include at least one camera directed at the patient. The systems and methods may obtain a plurality of images of the patient that are captured by the at least one camera. Each of the plurality of images may correspond to one of a series of time points. The systems and methods may also determine a motion of the patient over the series of time points based on the plurality of images of the patient. The systems and methods may further determine whether the patient is ready for scan based on the motion of the patient, and generate control information of the imaging system for scanning the patient in response to determining that the patient is ready for scan.
Systems and methods for orthosis design
The present disclosure is related to systems and methods for orthosis design. The method includes obtaining a three-dimensional (3D) model associated with a subject. The method includes obtaining one or more reference images associated with the subject. The method includes determining, based on the 3D model and the one or more reference images, orthosis design data for the subject. The orthosis design data may be used to determine an orthosis for the subject.
MODEL-BASED IMAGE SEGMENTATION
Presented are concepts for initialising a model for model-based segmentation of an image which use specific landmarks (e.g. detected using other techniques) to initialize the segmentation mesh. Using such an approach, embodiments need not be limited to predefined model transformations, but can initialise a segmentation mesh with arbitrary shape. In this way, embodiments may provide for an image segmentation algorithm that not only delivers a robust surface-based segmentation result but also does so for strongly varying target structure variations (in terms of shape).
SYSTEM AND METHOD FOR GENERATING THREE DIMENSIONAL GEOMETRIC MODELS OF ANATOMICAL REGIONS
A three-dimensional geometric image of an anatomical region is generated from a plurality of two-dimensional echographic image slices of the region. The image slices are filtered using a reaction-diffusion partial differential equation model before being arranged into a voxel space. Each voxel is then assigned a voxel value to create a volumetric data set from which the volumetric image can be rendered. The image is rendered from far to near, relative to a preset viewing direction, by an alpha-blending process. The alpha value at any given voxel can be determined using the magnitude of the density gradient vector at that voxel. Similarly, the direction of the density gradient vector at a given voxel can be used as a surface normal vector for shading purposes at that voxel.
ENHANCED PLANNING AND VISUALIZATION WITH CURVED INSTRUMENT PATHWAY AND ITS CURVED INSTRUMENT
Exemplary methods and systems that provide a curved path trajectory that can be used with a bendable medical device. The curved pathway can comprise straight and curved concatenated arc segments. The methods and systems can provide planning, visualizing and treatment of, for example, temporal lobe epilepsy (TLE) using laser interstitial thermal therapy (LITT) or tumors using ablation therapy. With curved pathway, the physician can create plan for intervention to avoid critical structure and to cover more target volume for treatment/diagnosis than straight pathway

VOLUMETRIC DYNAMIC DEPTH DELINEATION
A method for visualizing two-dimensional data with three-dimensional volume enables the end user to easily view abnormalities in sequential data. The two-dimensional data can be in the form of a tiled texture with the images in a set row and column, a media file with the images displayed at certain images in time, or any other way to depict a set of two-dimensional images. The disclosed method takes in each pixel of the images and evaluates the density, usually represented by color, of the pixel. The disclosed method evaluates and renders the opacity and color of each of the pixels within the volume. The disclosed method also calculates and creates dynamic shadows within the volume in real time. This evaluation allows the user to set threshold values and return exact representations of the data presented.
