Ultrasonography (US) acts by preparing a map by creating the sound waves which get in touch with a surface or infiltrate the tissues and create an echo followed by the conversion of this echo into an image by the transducer [ 28].
At one point, two of the Snow Whites, most of the dwarves and McCarthy lay in a moaning, panting, undulating pile on the living-room floor that McCarthy intended as a visual echo of an image in Jack Smith's 1963 underground transvestite romp, "Flaming Creatures".
A computer transforms these echoes into an image that is displayed on a monitor.
A computer transforms these echoes into an image that is displayed on a small screen.
The cow picture has echoes of an image released in May by West Midlands police of three lambs being transported in a Ford Galaxy people carrier.
Compared with the sub-millisecond echo times needed for the gradient echo sequences such a longer TE is easier to realise; however, with an inter-echo spacing of about 4 ms, a typical echo train for an image with 192 phase encoding steps still amounts to 192 × 4 ms = 768 ms.
Unlike ultrasound for medical imaging (which transmits ultrasonic waves and processes a returning echo to generate an image), therapeutic ultrasound is a one-way energy delivery which utilises a crystal sound head to transmit acoustic waves at 1 or 3 MHz and at amplitude densities between 0.1 and 3 W/cm2 [ 16, 19].
19) never seem to tire of discharging their six-shooters directly into the camera's lens — a shot that echoes a famous image from the sensationalistic hit of 1903, "The Great Train Robbery".
In a photo shoot for Rolling Stone, he dressed as Jesus with the word "atheist" scrawled across his bare chest; on another magazine cover, echoing a famous image of Muhammad Ali, he dressed as Saint Sebastian.
Baker's final artistic creation is an eerie echo of Thomas Keene's, an image of Mother Earth, half living, half dead, half male, half female.
A computer is then used to interpret these echo waveforms to construct an image [ 61].
