20130288249 | Dynamic Range Methods - The present invention relates to methods for detecting and quantifying an analyte in a sample, principally in proximity probe assays, and in particular to an improvement in such methods to extend the dynamic range of detection, which is particularly advantageous for the detection and quantification of an analyte where the concentration range of the analyte in said sample is unknown and/or the range is likely to be broad, said method comprising: (i) contacting said sample with at least a pair of proximity probes each comprising a proteinaceous target-binding domain coupled to a nucleic acid domain such that said nucleic acid domains may be allowed to interact directly or indirectly when the proximity probes have bound in proximity to their respective target, said target being either the analyte or a binding partner for the analyte; (ii) further contacting said sample with at least one set of markers which function to extend the dynamic range of detection of the method, wherein said set comprises at least two markers, wherein each marker is a nucleic acid molecule comprising a binding domain and a reporter domain which gives rise to a detectable signal, and each marker: (a) is capable of interacting either with said nucleic acid domains to form a nucleic acid molecule from which a detectable signal is generated, or with a nucleic acid molecule generated by interaction of said domains; (b) cannot interact with said nucleic acid domains simultaneously with another marker in the set; (c) generates a signal that is distinguishable from the signal of another marker in the set; and (d) is present in an amount capable of detecting the analyte at a range of concentrations that differs from the range of concentrations detectable by other markers; (ii) allowing said markers to interact with said nucleic acid domains or said generated nucleic acid molecule; and (iii) detecting said signal. | 10-31-2013 |

20140170654 | Unfolding Proximity Probes and Methods for the Use Thereof - The present invention relates to a proximity-probe based detection assay for detecting an analyte in a sample and in particular to a method that comprises the use of at least one set of at least first and second proximity probes, which probes each comprise an analyte-binding domain and a nucleic acid domain and can simultaneously bind to the analyte directly or indirectly, wherein the nucleic acid domain of at least one of said proximity probes comprises a hairpin structure that can be unfolded by cleavage of the nucleic acid domain to generate at least one ligatable free end or region of complementarity to another nucleic acid molecule in said sample, wherein when the probes bind to said analyte unfolding said hairpin structure allows the nucleic acid domains of said at least first and second proximity probes to interact directly or indirectly. | 06-19-2014 |

20080316226 | Method For Displaying High Resolution Image Data Together With Time-Varying Low Resolution Image Data - A method allowing display of time-varying merged high resolution and low resolution image data with a smooth frame rate. In one embodiment the high resolution data is structural image data and the low resolution image data is functional image data. The functional image data is gathered ( | 12-25-2008 |
20110299747 | FUNCTIONAL IMAGING - A method includes obtaining an image of a region of interest of a subject, wherein the image is generated with image data produced by an imaging system used to scan the subject, obtaining a signal indicative of a physiological state of the subject before the scan, and displaying both the image and data indicative of the physiological state. In another aspect, a method includes correcting, via a processor, a tracer uptake value for a target region of interest based on a tracer uptake correction factor. | 12-08-2011 |

20120063657 | METHOD AND DEVICE FOR SIDE-EFFECT PROGNOSIS AND MONITORING - A method for radiotherapy monitoring is provided. The method comprises calculation of treatment-guiding indices of side-effects based on processing image derived descriptors and measurement values of selected disease specific biomarkers and optionally questionnaire data. A computer program product is also provided. | 03-15-2012 |
20120290324 | DIAGNOSTIC TECHNIQUES FOR CONTINUOUS STORAGE AND JOINT ANALYSIS OF BOTH IMAGE AND NON-IMAGE MEDICAL DATA - An apparatus comprises: a database ( | 11-15-2012 |
20130024126 | METHOD AND A CORRECTION SYSTEM FOR CORRECTING TRACER-UPTAKE MEASUREMENTS - This invention relates to a method and a correction system for correcting tracer-uptake measurements for patient specific variations in the tracer-uptake. Input data are received about the patient and subsequently it is determining whether the received input data include tracer-impact data that impact the tracer-uptake measurements for the patient. In case the tracer-impact data are included in the input data a comparing is performed where the tracer-impact data are compared with pre-stored reference data that have associated thereto a correction indicator indicating an amount of deviation of the tracer-uptake measurement due to the tracer-uptake dependent data. The correction indicator of the pre-stored reference data that match with the tracer-impact data is then used to correct the tracer-uptake measurements for the patient. | 01-24-2013 |

20120203469 | METHOD OF EVALUATING TOXICITY LEVEL OF A PATIENT UNDERGOING A CANCER TREATMENT - This invention relates to a method and a system of evaluating toxicity level of a patient undergoing a cancer treatment protocol. Patient's related data including biomarkers of toxicity level caused by said cancer treatment are received. These biomarkers of toxicity level are then compared with a range of reference biomarkers of toxicity level caused during a similar cancer treatment. Finally, an alert signal is issued in case the biomarkers of toxicity level fall outside said range of reference biomarkers of toxicity level. | 08-09-2012 |
