摘要： The invention relates to a tomographic apparatus for the three-dimensional modelling of an object (2) to be imaged, said tomographic apparatus comprising at least one irradiation source (6) for irradiating the object to be modelled from at least two different directions, and at least one receiving means (8) for receiving the radiation transmitted through the object. The reconstruction parameter is a parameter which determines the behavior in iteration of a reconstruction representing the object to be modelled. The tomographic apparatus comprises means for modelling an object to be imaged by using a non-iterative tomographic modelling algorithm for determining reconstruction parameters for a more accurate computation to be conducted with an iterative tomographic modelling algorithm, in which the computation is conducted from a region of interest in the object.

摘要： The object of the invention is an arrangement for medical imaging comprising a radiation source (5) for generating the radiation required for imaging directed from at least one imaging angle at the object being imaged and radiation receiving means (6) for receiving the radiation that has passed through the object for producing the image data. The arrangement comprises automated image processing means (2) for identifying the anatomy of the object being imaged on the basis of image data produced from at least one imaging angle and for carrying out image processing on the basis of the said identified anatomy so that image data comprising image parameters is produced of the part of interest in the object imaged.

摘要： The invention relates to a method (100), system and computer program product for reconstructing a model of an object of projection data advantageously gathered by X-ray imaging. It is characteristic for the invention, that after a point of at least one object of interest from at least two projection images is marked as a seed point (106), where said point locates inside the object of interest in the corresponding projection image, the model of the object of projection data is reconstructed by adding (110) plurality of elementary object elements around the marked seed point in each direction until a criteria, such as likelihood criteria, is fulfilled in said direction, where priori information relating to the object of interest is connected (108) with said elementary object element.
