Abstract: A method and system for personalized computation of tissue ablation extent based on medical images of a patient is disclosed. A patient-specific anatomical model of the liver and liver vessels is estimated from medical image data of a patient. Blood flow in the liver and liver vessels is simulated. An ablation simulation is performed that uses a bio-heat model to simulate heat diffusion due to an ablation based on the simulated blood flow and a cellular necrosis model to simulate cellular necrosis in the liver based on the simulated heat diffusion. Personalized tissue parameters of the bio-heat model and the cellular necrosis model are estimated based on observed results of a preliminary ablation procedure. Planning of the ablation procedure is then performed using the personalized bio-heat equation and the cellular necrosis model. The model can be subsequently refined as more ablation observations are obtained.

Abstract: A housing for a high voltage tank has a boiler which is open on one side and a circuit board cover which closes the boiler. At least one strain gauge is arranged on or in the circuit board cover such that it is expanded or compressed with a pressure-induced deformation of the circuit board cover. A housing of this type is particularly suited as a high voltage tank for an x-ray emitter. An impermissible pressure in the housing for a high voltage tank can be determined easily and reliably.
Abstract: A method and system are provided for automatically positioning a medical diagnostic device.

Abstract: In nuclear medical imaging, respiratory motion is corrected. Rather than pairwise estimation of motion from projection views, a sequence-based technique is used to jointly estimate parameters for a motion model across many projection views. In one approach, this sequence-based method is iteratively solved with a maximum likelihood objective function incorporating the motion model. A surrogate respiration signal is used to gate for the joint estimation and used to convert gated motion parameters to temporal motion parameters.

Abstract: Disclosed herein is a framework for facilitating thermal patient signal analysis. In accordance with one aspect, the framework receives patient signal data including thermal signal data. The framework then segments a waveform of the thermal signal data into portions and extracts thermal parameters based on the segmented portions. The framework then determines one or more thermal indices based at least in part on the thermal parameters and generates a report that presents cardiac event detection results determined based at least in part on the one or more thermal indices.
Abstract: A method of acquiring magnetic resonance imaging (MRI) data from an MRI scan of an object includes generating a number of excitation sequences by, in order: generating an excitation pulse, generating an imaging magnetic field gradient, and generating a spoiler magnetic field gradient. MRI data is acquired during the generation of the spoiler magnetic field gradients. The spoiler magnetic field gradients are selected such that, during each excitation sequence, substantially the same k-space trajectory is traversed during the generation of the spoiler magnetic field gradient.

Abstract: A framework for isolating an aneurysm and parent vessel in volumetric image data is provided herein. In accordance with one aspect, the framework generates a refined mask by performing region growing starting at an aneurysm dome point to eliminate vessels that are indirectly connected to an aneurysm or parent vessel in volumetric image data. A final mask may be generated based at least in part on the refined mask by eliminating any kissing vessel connected with the aneurysm from the refined mask. The final mask may then be used for segmentation of the aneurysm and the parent vessel in the volumetric image data.

Abstract: In a method and apparatus for the automatic assignment of at least one combination image of an examination object to a spin species represented in a combination magnetic resonance (MR) image, an information MR dataset is obtained and evaluated in a computer to determine information about the examination object from the captured information MR dataset. At least two MR datasets are acquired at one of at least two echo times in each case following an excitation by a multi-contrast measurement. At least one combination image is determined from the at least two MR datasets, and spin species represented in the at least one combination image are assigned on the basis of the information determined from the information MR dataset. By using additional information about the examination object determined by MR technology an automatic unambiguous global assignment of the correct spin species is enabled.

Abstract: A traffic monitoring system for a traffic area with parking surfaces for vehicles or a freely arrangeable row of vehicles includes overhead radar sensors oriented towards the area for capturing a chronological sequence of digital radar images thereof. An analyzing unit detects vehicles parked on the area and ascertains locations and dimensions thereof from the captured sequence and determines an occupancy state of the surfaces from a data comparison of the ascertained locations and dimensions of parked vehicles with configured geodata of surfaces. The parking surface is occupied or free for a vehicle, and a parking surface for a freely arrangeable row of vehicles is occupied or provided by one or more free parking spaces. An image output unit outputs a map view of the area with marked surfaces and the current occupancy state of the surfaces. The traffic monitoring system allows a more effective monitoring of the area.
