What's the difference between collimation and collineation?
Collimation
Definition:
(n.) The act of collimating; the adjustment of the line of the sights, as the axial line of the telescope of an instrument, into its proper position relative to the other parts of the instrument.
Example Sentences:
(1) The dual-probe system incorporates a central collimated probe for monitoring activity in the LV surrounded by an annular detector collimated in such a manner as to provide simultaneous real-time monitoring of the LV background activity.
(2) The second area of improved SPECT technology is camera collimation and related imaging techniques.
(3) Comparative clinical studies on temporomandibular joints (TMJ) between the LEGP and fan beam collimators also confirm the superior image quality obtained with the fan beam collimator.
(4) In work to determine whether X-radiation could be used to induce tumors of the colon in outbred Holtzman rats, a technique was devised so that only the descending colon could be irradiated with a collimated X-ray beam and tumorigenic exposures in the kilo-Roentgen range were delivered.
(5) In the RAO view with the collimator flat against the chest there was better resolution of the cardiac apex.
(6) As an initial feasibility study of computer-controlled radiation therapy, its application to produce wedge-shaped dose distributions by moving the collimator jaws has been evaluated.
(7) Analysis of the penumbra width of cross dose distributions, as a function of field sizes, allowed us to postulate that the dmax shift could be due to the phantom scattered photons, which in turn were generated by the collimator scattered photons.
(8) Larger detectors with converging collimation result in much higher photon input rates to the scintillation crystal in routine clinical studies than has occurred in the past.
(9) Neutron spectra at various locations in a phantom, irradiated by collimated beams of 14 MeV neutrons and neutrons from 252 Cf and Po-Be sources, were calculated using the Monte Carlo technique.
(10) Without scatter, the resolution was 4.7 mm (full width at half-maximum); in a scatter medium, the resolution was 5.3-10.0 mm with high resolution collimation and 7.7-18.8 mm with general purpose collimation, depending on filtering.
(11) Quantitative measurement of the scatter dose in polystyrene solid phantoms with a Farmer type chamber and effects of shielding blocks under the collimators were studied.
(12) Spatial resolution with parallel-hole or converging collimators was much less satisfactory with Ta-178 because of septal penetration by high-energy photons.
(13) Moving the collimator during imaging will reduce septal aberrations but will not increase resolution.
(14) The nonuniform response inherent in the use of the pinhole collimator has a significant effect, but with computer processing this is readily eliminated.
(15) The exchange of collimator pairs results in significant output differences but has a negligible effect on the depth-dose curves.
(16) This was consistent with the design of the line focus and the beam collimators used in this system.
(17) One-centimeter collimation contiguous scans through the chest were obtained in all patients.
(18) A further increase in photon utization is gained for small-organ imaging with converging collimators, which produce images with superior resolution and sensitivity to that obtained with equivalent parallel-hole collimators.
(19) Normal quantitative circumferential profile limits were established for a 30 degrees bilateral rotating slant-hole (RSH) collimator tomographic system.
(20) Central axis percentage depth doses and off-axis ratios measured with such a collimator show variations with the source-to-surface distance (SSD).
Collineation
Definition:
(n.) The act of aiming at, or directing in a line with, a fixed object.
Example Sentences:
(1) Collins said she asked Sullivan several questions, including who the women were.
(2) Results demonstrate that the development of biliary strictures is strongly associated with the duration of cold ischemic storage of allografts in both Euro-Collins solution and University of Wisconsin solution.
(3) First, Dr Collins is fear-mongering when he says that ‘lives will be lost’ as a result of our calculations.
(4) Collins later thanked the condemned man for what he said was the respect he showed toward the execution team and for the way he endured the ordeal.
(5) Rat livers were stored for 4 hr in cold Euro-Collins solution, transplanted orthotopically, and then perfused 2 hr later with oxygenated Krebs-Henseleit buffer, using a nonrecirculating system.
(6) People want real graphics, real Hollywood-type experiences,” said Collins, a games industry veteran before founding SuperAwesome.
(7) But Matt Collins of Exeter University said it was unlikely to cause an absolute cooling: "It could offset some of the warming, but really the greenhouse gas signal wins over the AMOC.
(8) (“The Dynasty of Bush” sounds like a terribly disparaging term for Linda Evans, Kate O’Mara and Joan Collins .
(9) 1) Short term follow-up study: Perfusion of the limb with Fluosol-DA solution significantly minimized edema formation and leakage of skeletal muscle enzymes (GOT, CPK) into the serum 5.5 hours after revascularization as compared to Collins sol., lactated Ringer's sol.
(10) Hopefully there can be some really great performances which will try to blow away the shadow that programme has caused.” But Kilty will face a strong field in the men’s 100m that includes five athletes who have gone under the 10 second barrier in 2015, including the Frenchman Jimmy Vicaut, the American Mike Rodgers and the evergreen Kim Collins.
(11) Comparison was also made with cephalometric roentgenograms of a patient with Treacher Collins syndrome and of a patient with progeria.
(12) The clinical study of the major cranio-facial malformations such as Apert syndrome, Treacher-Collins syndrome, Blepharophimosis and Bilateral Cleft Palate patients, lead us to note a similarity of the orbito-palpebral region.
(13) People will see the Donald Trump I know, not necessarily the one you see in the rallies,” Collins said.
(14) The technical difficulties can be avoided by en bloc removal, perfusion in situ with Collins solution, and bench surgery during graft preparation.
(15) With Jackie Collins announcing plans to self-publish a revised version of her novel The Bitch, even traditionally published authors are now dabbling in self-publishing, and the survey found this was to good effect: they earned 2.5 times more when self-publishing than did rejected authors or authors who went straight to self-publishing.
(16) Cautious conclusion should advise to use Collins solution when there has not been a long warm ischemia.
(17) Collins's claim came after a member of the bureau went to Bell Pottinger, as well as a number of other lobbying firms, posing as a member of the Uzbek government wanting to clean up the regime's image in the west.
