Figure 4 shows the features that are extracted from the upper right quadrant of a radar scan example.
In our CT skull scan example, as well as in many similar real-world medical images, we can see that the last slices of the sets contain very little data, located far from the image borders.

We used this to create subject-specific parametric regressors of each subject's estimated learning state during each sweep of the scan, examples of which are shown in Figure 6.
Furthermore, using fast read-out detectors (Pilatus 6M) large areas can be scanned, for example a grid scan of 225 images at 0.2 s per exposure takes only 99 s.
Applicants undergo several rounds of background and biometric checks — fingerprints and retina scans, for example — by multiple federal immigration and intelligence agencies.
Functional magnetic resonance imaging (fMRI) scans, for example, can reveal changes in brain activity, as evidenced by changes in blood flow, but it is difficult to use them to study infants because the subjects must remain absolutely still.
CAT scans, for example, are three times more available in the United States than in Canada.
Software has been cleared through the 510(k) pathway that allows for segmentation of 3D patient scans, for example CT or MRI scans, to be converted to a 3D representation of the anatomy.
Furthermore, the physicians who continue to treat patients in hospital emergency situations may try to defend themselves against malpractice lawsuits by ordering unnecessary tests or procedures -- x-rays and CT scans, for example -- but in doing so exposes the patient to potentially hazardous radiation.
