Patent number: 8187166Abstract: A system for the implementation of minimally invasive diagnoses and interventions in the inside of the body of a patient has an endo-robot that has a linear magnet and carries measurement instruments and/or instruments for taking specimens and/or for treatment. The endo-robot is freely mobile within the body of a patient. A magnet system accepts the examination region of the patient and generates a 3D gradient field for remotely-controls movement and orientation of the endo-robot in the patient's body by interaction with the linear magnet.Type: GrantFiled: August 29, 2002Date of Patent: May 29, 2012Assignee: Siemens AktiengesellschaftInventors: Rainer Kuth, Thomas Rupprecht, Maren Wagner

Patent number: 6338836Abstract: In an integrated asthma analysis and therapy determination method, a patient is administered hyperpolarized gas and an magnetic resonance (MR) scan is conducted to obtain a first MR image set, and the patient is then administered an allergen provoker and is again administered hyperpolarized gas and another MR scan is conducted, to obtain a second MR image set. This is followed by administering asthma therapeutics and again administering hyperpolarized gas to the subject, and another MR scan is conducted to obtain a third image data set. The first, second and third image data sets are compared among each other in order to determine the effect of the allergen provoker and the effect of the asthma therapeutics, in order to determine an appropriate medication dosage for the subject.Type: GrantFiled: September 28, 1999Date of Patent: January 15, 2002Assignee: Siemens AktiengesellschaftInventors: Rainer Kuth, Thomas Rupprecht

Patent number: 6334066Abstract: In a method for monitoring growth disorder therapy, a magnetic resonance image of a skeletal body portion, such as a hand, of a candidate for growth disorder therapy is obtained using an open magnetic resonance scanner and using an imaging sequence to produce a tomogram having a slice thickness which approximates the thickness of the hand. The number of visible wrist bones and the width of epiphysis joints in the magnetic resonance image is evaluated to obtain osteo age data, and the osteo age data, in conjunction with an atlas of compiled osteo age data, are used to determine the osteo age of the candidate for growth disorder therapy. The relationship between the osteo age of the candidate and the chronological age of the candidate is used to determine whether growth disorder therapy is required. If growth disorder therapy is administered, such as by administering a hormone, the above procedure is repeated after a predetermined time, and the status of the therapy is again evaluated.Type: GrantFiled: December 21, 1999Date of Patent: December 25, 2001Assignee: Siemens AktiengesellschaftInventors: Thomas Rupprecht, Rainer Kuth

Patent number: 6308705Abstract: In a lung therapy method, hyperpolarized gas is administered for one breath to a subject, and a magnetic resonance scan of at least one lung of the subject is conducted. The data obtained from the scan are evaluated, specifically to determine the extent and distribution of infusion of hyperpolarized gas in the lung, as an indication of the alveolae in the lung which are open. Based on the evaluation of the data obtained in the magnetic resonance scan, a determination is made as to whether administration of a surfactant is necessary in order to improve opening of the lung. If a surfactant is administered, the procedure can be repeated to obtain an updated dataset, which can be evaluated to determine whether the administered surfactant has been effective.Type: GrantFiled: December 21, 1999Date of Patent: October 30, 2001Assignee: Siemens AktiengesellschaftInventors: Thomas Rupprecht, Rainer Kuth

Patent number: 5506567Abstract: A process for monitoring an opening of an enclosed space by an IR alarm system, wherein: a measuring process is generated whereby a modulated IR beam is emitted by at least one IR emitting element of an optoelectronic unit in the form of a pulse and the beam reflected from marginal areas of the opening is detected as a measurement signal by at least one IR receiving element of the optoelectronic unit, with the directional characteristic of th IR beam being matched, by optical components in the path of the beam, to the opening being monitored; the measurement signal detected by the receiving element is compared with a mean value of the previous measurement signals, and a normal operating mode of the alarm system is initiated if there is an approximate correlation between the measurement signal and the mean value, or an alarm operating mode of the alarm system is initiated if there is a significant deviation between the measurement signal and the mean value; in the normal operating mode, the next measuring procType: GrantFiled: September 26, 1994Date of Patent: April 9, 1996Assignee: Temic Telefunken microelectronic GmbHInventors: Gunther Bichlmaier, Ferdinand Friedrich, Dieter Grafje, Udo Teubert, Hans-Joachim Fach, Thomas Rupprecht, Reiner Doefler, Rainer Ertel, Gerhard Hettich, Werner Wiedemann, Peter Robitschko, Bernhard Dilz
