Temporal Contiguity. Temporal contiguity occurs when two stimuli are experienced close together in time and, as a result an association may be formed. In Pavlovian conditioning the strength of the association between the conditioned stimulus (CS) and the unconditioned stimulus (US) is largely affected by temporal contiguity.

Systems, devices, and methods for more accurately determining a radiopharmaceutical dose administered to a patient by relying on a time factor. Particularly, broadly contemplated herein is the administration of a dose on the basis of an elapsed time from when a dose was last accurately measured in the past to when it is injected into the patient. As such, when a dose is first measured, that timepoint is preferably recorded whereupon the time of injection or administration into a patient is also recorded. Based on the original measured dose, the radionuclide (and thus its known decay rate) and the time elapsed, the dose is calculated and not directly measured on injection. The clocks on the filling station and the transport cart are synchronized to each other or to a known and accepted time standard. In this manner, there is temporal continuity and no inaccuracies of time or loss of time occurs between measurement and injection.

The invention relates to a time-space domain multi-field related de-interlacing technology, which is convenient to realize by hardware. The invention provides a de-interlacing method with time-space domain information based on a movement adaptive algorithm. Different from moving state directed by an ordinary movement adaptive algorithm, that is field-in interpolation, the invention still searches for related points in a small scale of adjacent fields when it judges that it is in the moving state. It further determines specific interpolation method of next step by comparison with a predetermined value. The predetermined value ensures inter-field direction correlation of current field enough, which makes inter-field pixel points with large direction correlation participate interpolation calculation. It consumes less hardware resources compared with various search algorithms of movement compensation and is added with time domain information compared with movement adaptation, which makes the interpolation result in movement condition have time continuity.
