Brain CT scan Improvement

o ~ 100mA, 3 秒 so that each layer of brain scan can save the patient, the tube less exposure time, scan time shorter forks, fork is not missing small lesions, the diagnosis of no effect. Principles and methods for GE9800CT scanner, brain CT scan with 256 × 256mm matrix. Cable size = display as wild (F () V) / Matrix (Matrix) a 25O × 250mm/256 × 256rnm = 0.95xO. 95ram; the fault level, the thickness of the collimator depends on the length of long axis, slice thickness should be larger than the pixels. The smaller the pixel, the greater the number, the composition of the more detailed images that the high spatial resolution. Density resolution is also high. As the aircraft near the pixel size 1.0 × 1.0mm, and we used brain CT scan slice thickness was 10mm, which 1o ~ 11 pixels of the superimposed layers,[link widoczny dla zalogowanych], or a 10mm. ~ 1995 fold brain imaging technique and the third image. Using interval 10mm, that layers do not leave gaps between; and using interval 11mm. That is 1mm between the layers between the air, or a 1mm thick brain tissue failed to sweep Ilmm thick tissue which is equivalent to 1 pixel thickness; and GE980OCT scanner density resolution of 0.5 to 1. 2mm, so even if the lesion diameter lmm. CT scanners in general is difficult to sweep; even in the sweep in 10ram thick. The pixel stack. Difficult to show normal brain tissue of different density level I scan Moreover, because of the thinner. The higher the required conditions. Tube damage more too, generally difficult to use; while for larger lesions,[link widoczny dla zalogowanych], generally in the adjacent layers or layer can be displayed. The new scanning method is based on the baseline scan lines adjacent the ear (0M line). Were 1lmm, 2Zmm, 33mm, 44ram, 55ram, 66ram, 77mm, 88mm, 99ram at the center. Left and right 5ram thick. Each slice thickness is 10ram, two intervals of 11mm, that is left between the layers have not been swept 1ram thick tissue, conditions still 120kv, 70 ~ 100mA, 3 seconds. Discuss our GE9800CT CT scanner scan on the brain scan patients l5 ・ new scanning method, in the voltage, mA and scan time under the same conditions, to obtain a satisfactory image. And 1, the resulting image scanning method compared to the various parts of the brain showed no significant difference in organizational structure to meet the requirements of the diagnosis of cerebral disease, but near the top of the parietal bone lesions or posterior fossa lesions, should be added to scan 1 Layer 2 or do posterior fossa TLC. The CT scan method of scanning machines are generally applicable. In addition, this method can shorten the scan time, not increase tube wear and tear, but also reduce the amount of x ray exposure. On the contrary, according to our patients a year to sweep the 3500 head count, you can save 31,500 times the exposure tube,[link widoczny dla zalogowanych], saving nearly 3 hours of exposure time. Can more brain scan nearly 400 patients. This method can also be used to obtain substantial economic income,[link widoczny dla zalogowanych], according to the provisions of the province. Charges within the 10-story 200. 20 yuan each per year more than ten million in revenue desirable mattress. In short, we believe that a new method of brain scanning technology. Both diagnostic purposes can be achieved, but also can reduce tube wear and tear, extending tube life, and increase revenue in a variety of common CT scan machine can be used. (Continued from page l3) 5.2 to improve accuracy of measurement and control systems to meet the photosensitive material, the high-tech fine chemical products, quality requirements, the need to introduce computer technology to strict control, so that means the cabinet of the process} fluctuations were within a narrow range, and weighing of solid materials and liquid materials,[link widoczny dla zalogowanych], measurement accuracy, so that the final oil emulsion narrow particle size distribution, average particle size between batches small fluctuations. Uniform physical and chemical properties. Given the current oil emulsion particle size is difficult to achieve on line. When the formula must take into account, the size and existence of correspondence between viscosity, and the size recommended viscosity is directly related to the determination of the performance to replace, in the discharge port before the piston to increase the viscosity line detector, the instrument can be: for the detection of high viscosity liquids, when the viscosity of fluctuations, it will loop to the liquid inlet of the second were again dispersed to form a closed loop until the required viscosity of the indicators that the product quality fully meet the requirements, which increase the product quality to a new level. 6 References 1 \1gg0, 62U.
