Publication number: 20190204401Abstract: Techniques are disclosed to leverage the use of convolutional neural networks or similar machine learning algorithms to predict an underlying susceptibility distribution from MRI phase data, thereby solving the ill-posed inverse problem. These techniques include the use of Deep Quantitative Susceptibility “DeepQSM” mapping, which uses a large amount of simulated susceptibility distributions and computes phase distribution using a unique forward solution. These examples are then used to train a deep convolutional neuronal network to invert the ill-posed problem.Type: ApplicationFiled: December 31, 2018Publication date: July 4, 2019Applicant: Siemens Healthcare GmbHInventors: Kieran O'Brien, Markus Barth, Steffen Bollmann

Publication number: 20190204402Abstract: The invention relates to liver diseases. Liver diseases notably encompass chronic liver disease and liver cancer (a liver primitive cancer or metastasis). There is therefore a need to be able to extract biomarkers for subjects to suffer from this disease. As a consequence, the inventors worked on a method for post-processing images of a region of interest to obtain at least one perfusion parameter and at least one transport parameter. Such method enables to obtain a method which can be implemented on computer and provides access to relevant parameters for liver diseases in an easier and more accurate way. This method may be applied for predicting that a subject is at risk of suffering from such disease, diagnosing a disease, identifying a therapeutic or a biomarker and screening compounds useful as a medicine.Type: ApplicationFiled: September 13, 2017Publication date: July 4, 2019Inventors: Benjamin LEPORQ, Jean-Luc DAIRE, Bernard VAN BEERS

Publication number: 20190204403Abstract: The present disclosure relates to a location determination system that includes acoustic transmitting devices and mobile devices. A mobile device receives acoustic signals (e.g., ultrasound signals) from an acoustic transmitting device. The mobile device must be able to identify the acoustic transmitting device with particularity when receiving the acoustic signals. It is more efficient to use a short identifier, for example 6 bits, for this purpose because it requires less power to transmit and decode. By utilizing the rotating identifier system described herein, more acoustic transmitting devices can be distinguished than using a time-invariant identifier would otherwise provide, and the transmissions are more secure and therefore less vulnerable to free-riders.Type: ApplicationFiled: December 29, 2017Publication date: July 4, 2019Applicant: Sonitor Technologies ASInventors: Wilfred Edwin BOOIJ, Endre BAKKA, Fritjof Boger ENGELHARDTSEN
