摘要： Computer processing techniques are described for simulating grating-based X-ray phase contrast imaging systems. According to an example, a system comprises a memory that stores computer-executable components and a processor that executes the computer-executable components stored in the memory. The computer-executable components comprise a simulation component that simulates performance of an X-ray phase contrast imaging system using a simulation model, wherein the simulation model comprises a decomposition component that decomposes a virtual object into different sub-objects associated with different physical properties, and a projector component that separately models different changes to a baseline interference pattern received at a detector of the X-ray phase contrast imaging system respectively attributed to the different sub-objects in association with simulated projection of an X-ray beam through the different sub-objects.

摘要： A system and method for automatically analyzing placenta insufficiency in a curved topographical ultrasound image slice is provided. The method includes acquiring, by an ultrasound system, an ultrasound volume of a placental anatomy section, the ultrasound volume comprising color Doppler information. The method includes extracting, by at least one processor of the ultrasound system, a topographical ultrasound image slice at a distance below an inner surface of the placental anatomy section. The topographical ultrasound image slice is curved in all three dimensions and includes the color Doppler information. The method includes analyzing, by the at least one processor, the color Doppler information of the topographical ultrasound image slice to generate perfusion data information. The method includes causing, by the at least one processor, a display system to present the topographical ultrasound image slice with the perfusion data information.

摘要： Various methods and systems are provided for a microelectromechanical systems (MEMS) device. In one example, the MEMS device may include a silicon wafer with a first oxide coating, a cavity in the first oxide coating having a substantially flat floor formed of a layer of the first oxide coating and etched to a first depth prior to deposition of a masking layer, and a membrane coupled to the silicon wafer and spaced away from the substantially flat floor of the cavity by a second depth of the cavity. The second depth is a sum of the first depth and a height of a second oxide coating formed at the post regions of the MEMS device after the masking layer is removed from the post regions.

摘要： To document features of interest observed in a scanning procedure, after the images have been obtained the technician reviews the images on the imaging system and places virtual markers on the images (i.e., the 2D image or 3D volume) created by the imaging system. The virtual markers identify the type and location of the various features of interest observed during the imaging or scanning procedure and are placed directly on the images. Notes can also be added to the images, such as with regard to each of the virtual markers placed on the image. These virtual markers and optional notes communicate additional information regarding the patient and the image in a direct, efficient and comprehensive manner directly to the physician during later review of the images which would not be readily discernable solely from the image.

摘要： Various methods and systems are provided for an electro-acoustic module for a transducer probe. In one example, the electro-acoustic module may include an acoustic stack and at least one application-specific integrated circuit (ASIC) electrically coupled to the acoustic stack by an interconnect having a fan-out architecture. The electro-acoustic module may have an active aperture substantially equal to an overall size of the electro-acoustic module in at least one or an azimuth and an elevation direction.

摘要： A system may include a processor-based device configured to store or access a ranking application. When executed on or in communication with the workstation, the ranking application may determine a purpose of an exam request based on one or more attributes of the exam, retrieve a plurality of documents from a database based on the determined purpose, and assign a relevancy score to each of the plurality of documents based on a user profile. The ranking application may also create a list comprising the plurality of documents, wherein an order of the plurality of documents is based on the relevancy score and populate a graphical user interface (GUI) with the list for display on the workstation.
