Abstract: A method for automated detection of water accumulation in a ventilator, comprising: (i) a plurality of iterations of: calculating an airway pressure water accumulation index; calculating a flow water accumulation index; labeling, using a trained asynchrony detection algorithm, the single breath of the patient as synchronous or asynchronous, and ranking all of the input features based on an importance of each respective input feature to the synchronous or asynchronous determination; (ii) for the plurality of iterations; determining, a most frequent breath labeling, a most frequent most important input feature, and a most frequent most important input feature for each type of breath; and determining one or more of: (1) water accumulation and an action to remove the water accumulation; and (2) asynchrony due to a cause other than water accumulation, and an action to correct the asynchrony; and (iii) notifying a user of the determined action.

Abstract: X-ray sources emit X-rays into an examination region along different projection views. An X-ray detector array detects the X-rays emitted by the X-ray sources after passing through the examination region. X-ray imaging data are acquired by cycling through the X-ray sources with each step of the cycle including: switching an active X ray source on to emit X-rays and the other X ray sources off to not emit X rays, and acquiring X ray imaging data along the projection view corresponding to the active X-ray source that is switched on. Tomosynthesis image reconstruction is performed on the X ray imaging data to generate at least one volumetric image. A time sequence of spatially aligned images is produced from the time sequence of volumetric images. A perfusion image and/or a ventilation image is generated based on voxel intensity variation over time of the time sequence of spatially aligned images.
