An imaging apparatus for use with an imaging device in order to image a subject. The imaging device includes an annular gantry having an opening and a table to accommodate the subject or a portion thereof for imaging. The imaging apparatus includes a platform and a positioning device. The imaging device is mounted to the platform. The annular gantry is in a fixed position relative to the platform. The table is horizontally displaceable relative to the annular gantry. The positioning device supports the platform and is configured to horizontally displace the platform relative to a supporting surface for the subject. The positioning device is configured to position the platform with the imaging device in at least one operational state in such a way that, during a relative movement of the table with respect to the annular gantry, the table remains stationary relative to the supporting surface.

An adaptive template image for registering a PET or a SPECT image includes a template image model including variability of values for each voxel in a template image according to one or more control parameters.

Wearable apparatus and method of using same for tracking a labeled probe in a subject are disclosed.

A method is for computed tomography imaging. In an embodiment, the method includes provisioning a CT data set of an object, the CT data set being previously recorded via a multispectral recording method; suppressing a contrast, caused by a tissue type, and generating a contrast-suppressed data set from the CT data set provisioned; and analyzing at least the contrast-suppressed data set generated or a data set generated via a machine learning algorithm based on the contrast-suppressed data set, the analyzing being configured to identify at least one change in the tissue type. A corresponding device, a control device for a computed tomography system or a diagnosis system, and a diagnosis system and a computed tomography system are also disclosed.

Images can be generated with overlays indicating an amount of brain tissue damage based on the disruption of blood supply. Imaging data can be analyzed to determine perfusion parameters with respect to regions of the brain of an individual. The thresholds for the perfusion parameters with respect to the presence of damaged brain tissue can be based on a period of time elapsed since the onset of a biological condition disrupting blood flow to one or more regions of the brain of the individual. The imaging data can also be analyzed to determine measures of hypodensity with respect to regions of the brain of the individual. A likelihood of the measures of hypodensity corresponding to damaged brain tissue can also be determined based on the period of time elapsed since the onset of the biological condition.

The present disclosure provides a method for identifying sites for administering cells in cell therapy for central nervous system damage in a subject, comprising the steps of: A) acquiring image data on at least part of the subject's brain, with an imaging device; B) obtaining information on the subject's brain, with a computer device in communication with the imaging device; C) using the image data and data pertaining to the subject's brain acquired by the computer device to depict motor fibers; D) identifying damaged locations where motor fibers have suffered damage, with the computer device, identifying a portion where motor fiber run-data is lower than another portion and identifying the lower portion as being motor fibers that have suffered damage; E) using the computer device to select, as sites of administration, safe regions near the damaged locations; and F) outputting, as graphic display, the selected sites of administration.

A method of analysing data from an angiographic scan that provides three-dimensional information about blood vessels in a patient's brain, the method comprising the steps of: processing the data (26) to produce a three-dimensional image; extracting the system of blood vessels inside the skull, so as to obtain a vessel mask (28); skeletonising (30) the vessel mask with a thinning algorithm to produce a skeleton mask performing a central plane extraction; analysing (32) the skeleton mask to identify voxels that have more than two neighbours, indicating a fork, bifurcation or branch; detecting the most proximal location of each of the three main supplying arteries of the head in the skeleton mask to identify starting positions; and then starting from each starting position in turn, and walking along the line representing the corresponding blood vessel to detect (34) a plurality of anatomical markers within the network of blood vessels.

The present disclosure is related to systems and methods for image evaluation. The method may include obtaining an original image including a representation of at least one subject. The method may include generating a plurality of target positioning results for each of the at least one subject by inputting the original image into a prediction model. The prediction model may include a plurality of branches. Each of the plurality of target positioning results may correspond to a branch of the plurality of branches. The method may include determining an evaluation result corresponding to the original image based on the plurality of target positioning results.

A head stabilization system including a head restraint mechanism and a head harness configured to engage a head of a patient. The head restraint mechanism is configured to be operatively disposed on a patient support device and includes a generally vertically upstanding arcuate tilt guide. The head harness is releasably attachable to and at least partially supported by the head restraint mechanism. The head harness is selectively repositionable generally vertically relative to the tilt guide. The head restraint mechanism is configured to stabilize the head harness relative to the patient support device. The head restraint mechanism is configured to selectively allow lateral flexion of a neck of the patient, lateral rotation of the head of the patient, and extension and flexion of the neck of the patient.

Arrangements described herein relate to a headset. The headset includes a device. The device includes a transducer configured to interact with a head of a subject. The headset further includes a manually-operated registration system configured to delineate a workspace of the transducer at the head of the subject.
