Abstract: Phantom for verifying the calibration of PET scanners, comprising a substantially cylindrical body having a cross section with a convex curvilinear profile, and a plurality of spheres placed within said body, comprising a solid matrix of germanium-68, the phantom being characterized in that it further comprises a reference sphere filled with a solid matrix of germanium-68, said reference sphere being connected to the phantom in such a way that it can be removed and replaced in the same position.

Abstract: A method is described for automatic recognition of anatomical structures in images obtained by position emission tomography, comprising the steps of: acquiring a 3D matrix of standardized uptake values, SUVs, associated with a plurality of PET pixels in an anatomic volume of patient; calculating the Jacobian matrix of the matrix of standardized uptake values, SUVs, projections, in a predetermined anatomical direction, of the matrix of standardized uptake values, SUVs, or of its Jacobian matrix on an anatomic reference plane; locating a two-dimensional minimum of the matrix of standardized uptake values, SUVs, or of its Jacobian matrix, projected on the anatomic reference plane; locating a one-dimensional minimum in the anatomic direction of projection, corresponding to the coordinates of the two-dimensional minimum located on the reference anatomic plane of projection; and determining a center of gravity of the anatomical structure according to the coordinates of said two-dimensional and one-dimensional minim

Abstract: A method of managing a clinical trial includes verifying compliance with pre-determined data collection protocols in real time of medical data collected by peripheral clinical trial centers participating in the clinical trial, sending compliance verifications, collecting review reports submitted by the reviewers on the medical data, such as medical imaging data, according to a predetermined question-and-answer format, evaluating the answers in the review reports, for concordance, and transmitting at least one electronic notification pertaining to a result obtained from the evaluating, wherein at least one of the verifying, sending, collecting, evaluating, and transmitting is performed using at least one processor. A system for implementing the method also is provided.
