Publication number: 20220391760Abstract: The invention relates to a prediction system (100) for applying multiple trained models to an input instance, for example, for detection or segmentation of objects in a medical image. The multiple trained models form a combined model. A trained model determines a model output for an input instance by determining a representation of the input instance in a common latent space and determining the respective model output therefrom. The combined model further comprises dataset fingerprints of the multiple trained models, characterizing representations of its training instances in the latent space. To determine an output of the combined model for an input instance, correspondence scores are determined between the input instance and the multiple trained models, indicating correspondences between the input instance and the respective training dataset in the latent space. The combined model output is determined by combining respective models according to the correspondence scores.Type: ApplicationFiled: November 4, 2020Publication date: December 8, 2022Inventors: IRINA FEDULOVA, FEDOR MUSHENOK, HANS-ALOYS WISCHMANN

Publication number: 20220083814Abstract: A model may be trained on a training dataset, e.g., for medical image processing or medical signal processing tasks. Systems and computer-implemented methods are provided for associating a population descriptor with the trained model and using the population descriptor to determine whether records to which the model is to be applied, conform to the population descriptor. The population descriptor characterizes a distribution of the one or more characteristic features over the training dataset, with the characteristic features characterizing the training record and/or a model output provided when the trained model is applied to the training record. For instance, the model may be applied only to records conforming to population descriptor, or model outputs of applying the model to non-conforming records may be flagged as possibly untrustworthy.Type: ApplicationFiled: January 23, 2020Publication date: March 17, 2022Inventors: ROLF JURGEN WEESE, HANS-ALOYS WISCHMANN

Publication number: 20200129153Abstract: The present invention relates the device and the method for providing a guidance signal. The device preferably relates to a mobile device, such as a mobile tablet computer. The device comprises an input unit, a display and a processing unit. Via the input unit, a three-dimensional outline image of a surface of a human subject is provided, e.g. acquired by a camera. The device further comprises a memory. The memory stores a human reference model, which statistically represents a virtual human subject. In practice it is often the case that the surface outline represented by the human reference model would not instantly fit to the surface outline of the human subject. Therefore, the processing unit is configured to adapt the human reference model resulting in an adapted model, such that the surface outline represented by the adapted model fits to the surface outline of the (real) human subject.Type: ApplicationFiled: March 16, 2018Publication date: April 30, 2020Inventors: Julien Sénégas, Cristian Lorenz, Hans-Aloys Wischmann, Sascha Krueger

Patent number: 10101471Abstract: The invention relates to a characterization apparatus (1) for characterizing scintillator material (3) especially for a PET detector. A first radiation source (2) irradiates the scintillator material with first radiation (4) having a wavelength being smaller than 450 nm. Then, a second radiation source (5) irradiates the scintillator material with pulsed second radiation (6) having a wavelength being larger than 600 nm and having a pulse duration being equal to or smaller than 50 s, wherein a detection device (9) detects third radiation (12) from the scintillator material (3) during and/or after the irradiation by the second radiation. The third radiation depends on the amount of charge carriers trapped at electronic defects of the scintillator material such that it can be used as an indicator for the amount of electronic defects and hence for characterizing the scintillator material. This characterization can be performed relatively fast and in a relatively simple way.Type: GrantFiled: July 10, 2015Date of Patent: October 16, 2018Assignees: KONINKLIJKE PHILIPS N.V., IOFFE PHYSICAL TECHNICAL INSTITUTEInventors: Herfried Karl Wieczorek, Cornelis Reinder Ronda, Hans-Aloys Wischmann, Pavel Georgiyevich Baranov, Gaik Asatrian, Danil Olegovich Tolmachev

Patent number: 9414773Abstract: A respiratory motion determination apparatus determines respiratory motion of a living being (3). A raw data providing unit (2) provides raw data assigned to different times, wherein the raw data are indicative of a structure like the apex of the heart muscle, which is influenced by cardiac motion and by respiratory motion. A reconstruction unit (6) reconstructs intermediate images of the structure from the provided raw data. A structure detection unit (7) detects the structure in the reconstructed intermediate images. A respiratory motion determination unit (10) determines the respiratory motion of the living being based on the structure detected in the reconstructed intermediate images. This allows determining respiratory motion with high accuracy, without relying on, for example, a stable correlation between a tracking signal of an external respiratory gating device and respiratory phases.Type: GrantFiled: June 19, 2012Date of Patent: August 16, 2016Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Sven Kabus, Hans-Aloys Wischmann, Cristian Lorenz

Patent number: 8411915Abstract: Medical images are collected in a plurality of cardiac and respiratory phases. The images are transformed into a series of respiratory compensated images with the plurality of cardiac phases, but all at a common respiration phase. The series of respiratory compensated images are transformed into one image at a selected cardiac phase and the common respiration phase. In some embodiments, a database of gated transform matrices is generated. The database may be based on specific patient information or on information generated from a pool of patients. The database may account for respiratory motion, cardiac contractile motion, other physiological motion, or combinations thereof. For a current image to be motion corrected, the transformation matrices collected in the database are used to estimate a current set of transformation matrices accounting for the motion in the current image, and a motion-compensated image is generated based on the current set of transform matrices.Type: GrantFiled: July 27, 2006Date of Patent: April 2, 2013Assignee: Koninklijke Philips Electronics N.V.Inventors: Hans-Aloys Wischmann, Lingxiong Shao, Angela Da Silva, Ingwer C.

Patent number: 8232798Abstract: A magnetic tracking system is particularly adapted for a combination with an imaging system, for example with a rotational X ray device. The magnetic tracking system includes pairs of first and second field generators that are disposed on opposite sides of a measuring volume. The first field generators may particularly be attached to a radiation source and the second field generators to a detector of the X ray device. Moreover, the first and second field generators may be constituted by coils with opposite magnetic polarity. Due to the attachment of the field generators to the X ray device, motions of the X ray device do not disturb the magnetic field in a frame of reference fixed to the imaging system.Type: GrantFiled: August 28, 2006Date of Patent: July 31, 2012Assignee: Koninklijke Philips Electronics N.V.Inventors: Sascha Krueger, Hans-Aloys Wischmann

Patent number: 7652468Abstract: The invention relates to a device and a method for correction of the position (x) of a field sensor (4) measured by means of a magnetic localization device. External field distortions, such as caused for example by the rotating components (1a, 1b) of a computer tomograph (1), are then determined with the help of reference sensor (3) placed at a known position. It is possible to deduce, for example, the current angle of rotation (?) of the computer tomograph (1) from the measurement signals of the reference sensor (3). Based on an empirically determined correction (?(x, ?)), the uncorrected determined positions (x) of the field sensor (4) can then be converted to corrected positions (x?) in relation to the field distortions. The field generator (2) and the reference sensor (3) are preferably fastened to the gantry in order to eliminate the dependency of the field distortions on an inclination of the gantry.Type: GrantFiled: February 11, 2005Date of Patent: January 26, 2010Assignee: Koninklijke Philips Electronics N.V.Inventors: Sascha Kruger, Hans-Aloys Wischmann, Holger Timinger, Jorg Sabczynski, Jorn Borgert
