20110246103 | ARRANGEMENT AND METHOD FOR DETECTING AND/OR LOCATING A MAGNETIC MATERIAL IN A REGION OF ACTION - In Magnetic Particle Imaging (MPI) the reconstruction requires the knowledge of a so called system function. This function describes the relation between spatial position and frequency response and is currently measured once for a scanner set-up and a tracer material. For reasonable resolutions and fields of view the system function becomes quite large, resulting in large acquisition times to obtain reasonable signal-to-noise. However, the system function has a number of properties which can be used to improve signal-to-noise. According to the present invention use is made of the spatial symmetry and/or identical responses at different frequencies for this purpose. | 10-06-2011 |

20110237928 | ARRANGEMENT AND METHOD FOR DETECTING AND/OR LOCATING A MAGNETIC MATERIAL IN A REGION OF ACTION - In Magnetic Particle Imaging (MPI) the reconstruction requires the knowledge of a so called system function. This function describes the relation between spatial position and frequency response. For reasonable resolutions and field of views the system function becomes quite large, resulting in large acquisition times for the system function and high memory demand during reconstruction. The present invention proposes to reduce the size of the system function matrix by making use of structural properties of the matrix. Such properties are, for instance, spatial symmetries reducing the number of columns and identical responses at different frequencies reducing the number of rows. In other embodiments the matrix can be transformed to a sparse representation using appropriate base functions. | 09-29-2011 |

20130225979 | COLON SCREENING BY USING MAGNETIC PARTICLE IMAGING - The present invention relates to a method for colon screening by using Magnetic Particle Imaging comprising the steps of: (a) generating an imaging magnetic field with a spatial distribution of the magnetic field strength such that the area of examination in the colon consists of a first sub-area of the colon with lower magnetic field strength, where the magnetization of a magnetic particle which was pre-delivered to the colon is not saturated, and a second sub-area of the colon with a higher magnetic field strength, where the magnetization of said magnetic particle is saturated; (b) changing the spatial location of both sub-areas in the area of examination so that the magnetization of said particles changes locally; (c) acquiring signals that depend on the magnetization in the area of examination influenced by this change; and (d) evaluating said signals to obtain information about the spatial distribution of the signals in the area of examination. The area of examination in the colon preferably comprises a portion or segment of the colon and steps (a) to (c) may be carried out during an entire peristaltic cycle in said colon portion or segment. The present invention further relates to a corresponding method for collecting data, the use of a magnetic particle for colon screening via Magnetic Particle Imaging, a food stuff or liquid for in vivo diagnostic use comprising a magnetic particle, and a method for preparing a patient for colon screening by using Magnetic Particle Imaging. | 08-29-2013 |

20160109545 | VISUAL PRE-SCAN PATIENT INFORMATION FOR MAGNETIC RESONANCE PROTOCOL - A system and method determines an isocenter for an imaging scan. The method includes receiving, by a control panel, patient data generated by at least one sensor, the patient data corresponding to dimensions of a body of a patient. The method includes generating, by the control panel, model data as a function of the patient data, the model data representing the body of the patient. The method includes receiving, by the control panel, a target location on the model data, the target location corresponding to a desired position on the body of the patient for performing the imaging scan. The method includes determining, by the control panel, an isocenter for the imaging scan as a function of the target location. | 04-21-2016 |
