But in digital mammography, an electronic device records the number of X-rays going through each part of the breast, and this collection of numbers then appears as an image on the computer's two high-resolution monitors.
The X-ray spectrum, the number of X-rays at different energies, showed that the speed and density of the wind from J1655's disk corresponded to computer simulation predictions for magnetically-driven winds.
At the very least, Imam says, a transilluminating catheter could be inserted without the need for fluoroscopy or ultrasound, make bedside placements more accurate, and cut down on the number of x-rays required.
The child was taken into care after its mother noticed faint bruising and took it to hospital in January 2009, where a number of x-rays and examinations revealed several fractures.
And supernovae do put out a huge number of x-rays and gamma rays; even if a supernova is thousands of light years away, it will still dump gamma rays on us at a faster rate than the sun does during its most active periods (i.e. when it is undergoing solar flares).
Cutting the number of X-rays for lumbar spine or knee problems, which could save £221m.
They found that the number of x-rays collected during bursts oscillate at a frequency of 363 cycles per second.
The estimated total number of x-rays as a consequence of osteoporotic fractures was 304,199.
Generally, the EDS counts signify the number of X-rays coming from the different orbits of atoms.
"These are producing pulses of X-rays that are on the order of 10 to 40 femtoseconds long, so these are extremely short pulses, but there's a huge number of X-rays in each one," Caffrey explains.
