    摘要: A system and method for quantifying a region of interest in a medical image and in particular, a PET image. The system and method allow the clinician to make real time quantitative analysis of a region of interest. The system and method can be used to quantify small lesions within a region of interest by generating a set of virtual lesions for comparison with the actual lesion. Quantitative information, such as lesion size and tracer activity, or SUV, can be obtained to assist the clinician or physician in the diagnosis and treatment of the lesion.

    摘要: Accurate error estimates are beneficial for many applications of emission tomography, e.g. kinetic modelling or SUV quantification with confidence levels. Due to the variety of parameters influencing the noise properties of PET images, the use of a single error model for all imaging situations and data processing set-ups leads to inaccurate error estimates. The present invention circumvents this problem by providing a database that includes a plurality of pre-determined noise models for different imaging situations. The most appropriate noise model can then be selected manually or automatically depending on the given imaging situation. Hence, the time-consuming procedure of extracting correct noise models, e.g. by utilizing a bootstrap method or by analysing repeated measurements, needs to be performed only once for each model and can be done by the vendor of the acquisition system, so that the clinician can instantly access the optimized error models from the database.

    摘要: An apparatus includes a diagnostic scanner (102) and a treatment planner (112). The treatment planner (112) plans a treatment to be applied to an object. A treatment device (114) treats the object according to the treatment plan. A treatment scanner (108) scans the object during a treatment session. A motion modeler (116) uses information from the treatment scan to model a motion of the object. A motion compensated quantitative data generator (1004) uses data from the diagnostic (102) or other scanner, as well as feature geometry (1008) and feature motion (1006) information, to generate motion compensated quantitative data indicative of a feature of the object.

    摘要: An apparatus includes a scanner (102, 104) and a scanning motion monitor (100). A motion modeler (116) uses data from the scanning motion monitor (100) and the scanner (102, 104) to generate a motion model which describes motion of a region of interest of an object. A treatment planner (112) uses image data from the scanner (102, 104) to establish a treatment plan for the object. A treatment device 114, which operates in conjunction with a treatment motion monitor (108), uses the motion model to compensate for motion of the object during application of the treatment.
