Engineering advances in CT have produced multi-slice instruments that can scan large areas of the body in short periods of time, and such instruments now permit high resolution examination of entire anatomic regions (eg, the chest) in a single breath hold.
Twohy suggests that the "slaughterhouse," an uneasy analogy where the slicing instruments aren't knives but part of a video editing suite, does more than just provide shots of women's segmented body parts.
But he cautioned that using a shear, rather than a finer diamond-laced wire saw, as the slicing instrument resulted in a jagged cut, meaning that the containment cap will fit less snugly.
Thin sections were made using a LKB-5 type ultra-thin slicing instrument (LKB Nova, Bromma, Sweden).
It is possible, exploiting the technology to its maximum potential as regards speed, to perform an examination many times faster (depending on the number of detector rings from 4 to 64) even than with earlier single slice spiral instruments.
The desired tissue, once isolated, was placed in cold (4°C), oxygenated sucrose based physiological solution (in mM: sucrose 209, KCl 2, NaH2PO4 1.25, MgCl2 5, CaCl2 0.5, NaHCO3 26, D-glucose 10) for 90 s, and then cut with a vibrating tissue slicer (Precisionary Instruments, Greenville, NC, USA) into 300 µm sections in 4°C physiological solution.
The tissue block was cut in the epicardium-tangential plane, using a high precision vibratome (7000smz tissue slicer; Campden Instruments, Loughborough, UK) with a ceramic blade (Campden Instruments) at a progression speed of 0.03 mm/s (lateral blade vibration amplitude 2 mm, frequency 80 Hz).
The canal spaces of the root slices were instrumented by number 2 through number 5 Gates-Glidden burs (Mani, Utsunomiya, Japan) to form 1.3 mm diameter standardized cavities.
The brains are removed and placed in PFA (4% in PBS) over night, followed by sectioning to 200-µm slices using vibrating slicer (Vibroslice, Campden Instruments, Lafayette, IN, USA).
Certificates take the form of a bearer bond — a slice of the instruments engineered by the bank — and depend on the creditworthiness of the issuer.
Like PFIs, they will be traded as financial instruments, sliced and diced according to risk and sold on.
