A method and system for spatio-temporal (4D) modeling of an object includes sampling the 4-D model at one point in time to create a 3-D model. This 3-D model is then fit based on user-supplied guide points, image forces (e.g., image edges) and prior shape models. Once the 3-D model fit is completed the full 4-D shape model is updated. Cardiac images can be spatio-temporally modeled to determine LV conditions.

A method, system, and apparatus of determining optimal viewing planes for cardiac image acquisition, wherein the method includes acquiring a set of sagittal, axial, and coronal images of a heart, where the axial and coronal images intersect with the sagittal image orthogonally, and where the heart has a natural axis and a left ventricle (“LV”) with a bloodpool, a bloodpool border, and an apex. The method also includes making a map of the bloodpool border, and using the map to create a full coordinate frame oriented along the natural axis.

The invention provides a method of measuring characteristics of an organ or part thereof from multiple images of the organ or part thereof, the method comprising the steps of defining the spatial position of at least two of the images; defining a reference model of the organ or part thereof scaled according to the distance between reference markers on the images; defining one or more boundary guide points associated with one or more images for which the spatial positions have been defined; converting the guide points to three-dimensional coordinates; defining an estimate model by fitting the reference model to the guide points; and calculating the characteristics from the estimate model. The invention also provides a system and a computer program for measuring characteristics of an organ or part thereof of a subject from multiple images of the subject's organ or part thereof.

In an access controller and method for controlling access to medical data, the medical data being provided as at least one first file and a second file independent of the first file with findings regarding patients that are generated by medical personnel being stored in the first file and measurement results of patients that were acquired by means of a medical-technical apparatus being stored in the second file, with at least one subset of the measurement results stored in the second file forming the basis of at least a subset of the findings stored in the first file, the access controller is configured to detect the measurement results forming the basis of a stored finding. Links to the measurement results forming the basis of a respective finding are stored at the findings in the first file and the access controller is configured to automatically detect measurement results stored in the second file and form the basis of a finding, the automatic detection ensuing using the link stored at the respective finding in the first file.

In a method for acquisition of movement of a subject by magnetic resonance imaging, a pulse sequence is applied that spatially modulates the magnetization of the subject in one spatial direction, a spectral maximum of the image data in the Fourier domain representing the spatially-modulated subject is acquired by a three-dimensional imaging sequence with volume excitation of the nuclear spins, the acquired spectral maximum is Fourier transformed, and the movement of the subject is determined from the Fourier-transformed signal.
