1.The Application of Laser Collimation for Measuring Revolving Angle
2.Our Collimation Testers are lateral-shearing interferometers that can be used to examine and adjust the collimation of laser light.
3.Experimental Investigation on Self-collimation into Characteristic of Machine Bed Simulating Parts
4.A Formula of Deciding Weight by the Collimation Line Method for Great Dam Observation
5.STUDY ON THE SELF-COLLIMATION DESIGN PRINCIPLE OF MACHINE BED AND ITS APPLICATION TO GUIDEWAY GRINDER
6.The accuracy offocus-adjustment can exceed half of focus-depth and the accuracy of collimation can exceed10￣(-5) rad.
7.No significant difference in MLD was seen between scans with 3mm (-802±51HU), 5mm (-800±46HU) collimation using low dose and scans with 3mm (-805±49HU), 5mm collimation (-801±37HU) using standard dose, respectively (both P>0.05).
8.This point and objective focus of collimation lens are superposition. Though the collimation lens, the beam of light become parallel lights. Then though the Coude Reflector and radiation system of special prism, the lights become a beam of light with 3 ° emanative angle.
9.Methods Thin collimation multi-detector spiral CT pulmonary angiography (CTPA) and CT venography (CTV) were preformed in 21 patients suspected of acute PE.
10.Three CTA studies were done by multisection CT scanner (MX8000 four-slice CT, Marconi, USA) with a collimation of 2.5 mm, resulting in an effective slice width of 3.2 mm.
