Large areas need to be scanned rapidly without removal of individual components, minimising the disruption of the structure's operation.
Some evolutionary biologists claim that the scholarly mind is an historical anomaly: that humans, like other primates, are designed to scan rapidly for danger and opportunity.
A cylindrical phantom (d = 8 cm) containing concentrated aqueous sodium permanganate (2.7 M) was scanned rapidly by 55Mn MRI in a human head coil tuned for 13C, using a balanced steady state free precession acquisition.
The theory of contrast in the photocurrent image is presented: methods utilizing intensity modulated light are compared with those in which the spot is scanned rapidly without intensity modulation.
Since a method to determine the allowable maximum pulse repetition frequency depending on target materials and structures was found by investigating the residual wave caused from the previous laser impinging, our laser ultrasonic system can scan rapidly the target with an optimal pulse repetition rate.
In this way a thick slab of tissue could be scanned rapidly.
By sweeping between the extremes of deflector bandwidth at a given rate df / dt different focal planes could be scanned rapidly.
The treatment was administered by manually scanning the rapidly pulsed laser in an even painting motion throughout the entire treatment area.
The increased sensitivity can be used to acquire scans rapidly, i.e. within a single breath hold to minimize breathing artifacts or, alternatively, to reduce the patient-administered radioactivity 20-fold.
Radio tags can carry more information about the product, can be scanned more rapidly and can be found even if they are hidden in cartons or behind other products.
Nevertheless, the final detector of all images is invariably the human eye, and, whatever means is used to transmit and control the light, the final image must either be produced simultaneously or scanned so rapidly that the observer's persistence of vision will give him the mental impression of a complete image covering a finite field of view.
