摘要: A detector (2) for a positron emission tomography (PET)-scanning device is provided, the detector (2) including an opening (28) sized to accommodate the head of a human patient (P) and a plurality of sensor modules (22), which serve to detect emitted PET-radiation from the human patient (P) and which are arranged in the form of a regular polygon having a plurality of corners (24a, 24b, 24c). The detector further has an inner surface (23), which is arranged radially inside of the sensor modules (22), in order to circumferentially delimit the opening (28). The sensor modules (22) are arranged such that one of the corners is a nose corner (24a) which is adapted to accommodate the patient's nose (N) in the intended normal use of the detector (2). The inner surface (23) reflects the shape of the polygon at least in the region of the nose corner (24a).

摘要: Disclosed herein are methods that aid in the determination of whether to perform imaging, such as magnetic resonance imaging (MRI) or computerized tomography (CT) scan, on a human subject that has sustained or may have sustained an injury to the head using an early biomarker, such as ubiquitin carboxy-terminal hydrolase L1 (UCH-L1), glial fibrillary acidic protein (GFAP), or a combination thereof. These methods involve detecting levels and changes in levels of UCH-L1 in samples taken from a human subject at time points within 24 hours after the subject has sustained or may have sustained an injury to the head.

摘要: Disclosed herein are methods that aid in the hyperacute diagnosis and evaluation of a human subject that has sustained or may have sustained an injury to the head, such as mild, moderate, severe, or moderate to severe traumatic brain injury (TBI), using an early biomarker, such as ubiquitin carboxy-terminal hydrolase L1 (UCH-L1), glial fibrillary acidic protein (GFAP), or a combination thereof. Also disclosed here are methods that aid in the hyperacute determination of whether a human subject that has sustained an injury or may have sustained to the head would benefit from and thus receive a head computerized tomography (CT) scan based on the levels of UCH-L1. These methods involve detecting changes of levels of an early biomarker, such as ubiquitin carboxy-terminal hydrolase L1 (UCH-L1), glial fibrillary acidic protein (GFAP), or a combination thereof, in samples taken from a human subject at a time point within about 2 hours, such as about 10, 12, or 20 minutes, after the subject has sustained or may have sustained an injury to the head and a second time point about 3 hours to about 6 hours after the first sample is taken.

摘要: A surgical access assembly and method of use is disclosed. The surgical access assembly comprises an outer sheath and an obturator. The outer sheath and obturator are configured to be delivered to an area of interest within the brain. Either the outer sheath or the obturator may be configured to operate with a navigational system to track the location of either within the brain. Once positioned at a desired location, the obturator is removed, leaving a distal end of the outer sheath adjacent an area of interest, and creating a working corridor. Interrogation of the area of interest may be performed to evaluate a disorder and/or abnormality, as well as evaluate treatment regimes. Interventional devices may also be introduced to the area of interest, as well as a variety of treatments.

摘要: Various examples are provided related to predicting perfusion images from non-contrast scans. In one example, a method for predicting perfusion images includes generating perfusion maps of an organ of a subject from non-contrast computed tomography (NCCT) slices of the organ; processing the perfusion maps based upon weights determined by a Physicians-in-the-Loop (PILO) module; and generating synthetic computed tomography perfusion (CTP) maps from the processed perfusion maps, the synthetic CTP maps generated by deep learning-based multimodal image translation. In another example, a system includes at least one computing device that can generate prefusion maps of an organ from NCCT slices; process the perfusion maps based upon weights determined by a PILO module; and generate synthetic CTP maps from the processed perfusion maps using deep learning-based multimodal image translation. The CTP maps can be rendered for display to a user.

摘要: An X-ray detection unit includes an X-ray detector that receives and detects the X-ray beam transmitted through the head. The support supports the X-ray generation unit and the X-ray detection unit. A drive mechanism moves the support such that the X-ray generation unit and the X-ray detection unit turn about an axis extending in a direction parallel to an apparatus vertical direction and around the head. An X-ray generation source moving unit moves the X-ray generation source in the apparatus vertical direction. The X-ray imaging apparatus increases a spread in the apparatus vertical direction of the X-ray beam when the X-ray generation source is located on an apparatus upper side, and decreases a spread in the apparatus vertical direction of the X-ray beam when the X-ray generation source is located on an apparatus lower side.

摘要: An extra-oral dental imaging apparatus for obtaining an image from a patient has a radiation source and a digital imaging sensor that provides, for each of a number of image pixels, at least a first digital value according to a count of received photons that exceed at least a first energy threshold. A mount supports the radiation source and the digital imaging sensor on opposite sides of the patient's head. There can be a computer in signal communication with the digital imaging sensor for acquiring one or more two-dimensional images.
