Abstract: A computer-implemented method of tomographic reconstruction, the method comprising: receiving an input dataset comprising tomographic projection data of an object; and reconstructing an image of the object using an iterative reconstruction technique, wherein the iterative reconstruction technique seeks to minimize a cost function, the cost function including a first regularizer and a second regularizer, wherein the first regularizer is a first trained machine learning model, trained using image data associated with the object and extracted from a first direction and the second regularizer is a second trained machine learning model, trained using image data associated with the object and extracted from a second direction.

Abstract: A pipe connecting device designed for detachable, sealing assembly of two pipe ends which device consists of an outer part and an inner part inserted axially into the outer part and cooperating therewith for internal connection to the first pipe end. The cooperating contact surfaces of both the inner part and the outer part are conical in shaped. Furthermore, means are arranged to prevent axial movement between the conical contact surfaces.
