Healthcare services can be automated utilizing a system that recognizes at least one characteristic of a patient based on images of the patient acquired by an image capturing device. Relying on information extracted from these images, the system may automate multiple aspects of a medical procedure such as patient identification and verification, positioning, diagnosis and/or treatment planning using artificial intelligence or machine learning techniques. By automating these operations, healthcare services can be provided remotely and/or with minimum physical contact between the patient and a medical professional.

The present invention relates to a device (1) for the calibration of images, said device being made from a material (2) that is radiolucent to radiation that, upon striking a first object (3) of which the dimensions are to be obtained, projects the object onto a surface (4) that is sensitive to said radiation, thereby forming an image of the object (3) on the surface (4). The device (1) comprises at least one base (6) and at least two support surfaces (5) located at different distances from the base (6), said surfaces (5) being suitable for positioning a calibration object (7) that is opaque to the radiation and of known dimensions, and maintaining the object in position, such that the image formed by the radiation upon projection of the calibration object (7) onto the surface (4) is used to determine the real dimensions of the first object (3) or of parts of same.

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.
