Abstract: The present embodiments relate to a method for transmitting medical data records. The method includes receiving a patient data record from an internal data storage unit, selecting an anonymization setting from a set of predetermined anonymization settings, generating an anonymized patient data record on the basis of the selected anonymization setting or rule, and transmitting the anonymized patient data record to an external data storage unit.

Abstract: In a method for retrieval of similar findings from a hybrid image dataset, a database of hotspots is prepared, wherein the hotspots are identified by binary strings encoding descriptors, and identify binary strings stored in the database are identified that resemble a new binary string.

Abstract: A method for facilitating comparison of medical image data captured using first and second combinations of scanner and reconstruction protocol (‘systems’) includes using a modifier to modify image data of a first subject captured using a first system to reduce a difference from image data of a second subject captured using a second system.

Abstract: The invention addresses the problem of reproducibly estimating statistics in structurally significant regions of interest of medical volumes where the data is acquired as projections of a Cartesian-space distribution. The regions of interest (ROI) are specified to a high resolution using a spatial reference dataset, and these are mapped to the spatial frame of reference of the apparatus on which the data was acquired. This allows the regions to be projected on to the detector loci of the apparatus and ROI activity is estimated directly from measurement projections. The invention also addresses problems associated with poor delineation of ROIs.

Abstract: In a method and apparatus for determining a framing interval used when reconstructing medical scanning data such as Positron Emission Tomography (PET) scans, peak activity in the Blood Input Function Time Activity Curve is identified by regions of maximum rate of change and the framing interval is selected to include the peak in a frame. Once the framing interval is established, reconstruction of the data is performed by conventional methods.

Abstract: In a method and apparatus for calculation of a confidence measure indicating the validity of comparing medical scans such as PET or SPECT, the conditions for each scan are analyzed, with regard to conditions for various factors affecting Standardized Uptake Value (SUV). A scoring system assigns a score dependent on whether conditions are the same or different for each factor and the confidence measure is calculated from a combination of the scores, and a representation of the confidence measure is displayed.

Abstract: The invention addresses the problem of algorithm specific artefacts introduced by reconstruction of functional medical scans. After a general purpose reconstruction is performed, regions of interest are identified from the data and task specific reconstruction of the region(s) of interest is carried out. The reconstructed data can be displayed (for example) as a report or image overlay.

Abstract: A method is described for analysing the images produced by functional medical scans such as Positron Emission Tomography (PET), which method provides for an accurate estimation of Blood Input Function (BIF). An MRI scan and the functional scan is performed simultaneously and the results of the former is used to derive the BIF. The BIF so derived is then used in pharmacokinetic modelling along with the results of the functional scan.
