CT检查参数知识点

CT检查参数知识点

CT检查参数知识点CT(计算机断层扫描)是一种影像学技术,用于生成身体内部的详细图像。

在进行CT检查时,掌握一些基本参数和知识点是非常重要的。

本文将介绍CT检查的几个主要参数,包括扫描方式、层厚、峰值伏特数、螺旋扫描、重建方式和对比剂。

1. 扫描方式:CT检查可以使用两种主要的扫描方式:连续扫描和螺旋扫描。

连续扫描是一种通过连续扫描患者身体部位来获取图像的方法。

而螺旋扫描是一种通过将X射线管和探测器同时旋转以连续扫描身体部位的方法。

螺旋扫描速度更快,对于动态病灶的观察效果更好。

2. 层厚:层厚是指CT扫描中每个层面的厚度。

一般来说,层厚越薄,图像越清晰,但扫描时间也会相应增加。

层厚的选择取决于患者病情、检查目的和扫描器性能等因素。

3. 峰值伏特数:峰值伏特数是指CT扫描中所使用的X射线的电压大小。

峰值伏特数越高,图像对比度越高,但辐射剂量也会增加。

常用的峰值伏特数一般为100kV或120kV。

4. 螺旋扫描:螺旋扫描是一种通过移动X射线管和探测器的方式,连续获取图像的方法。

与传统的连续扫描相比,螺旋扫描可以更快地获取图像,并能够观察到动态病变的变化。

5. 重建方式:CT图像的重建方式有两种:传统重建和重建间隔。

传统重建是指将扫描获得的原始数据直接生成图像。

而重建间隔是指在连续扫描过程中,将采集到的数据间隔一定距离进行重建,从而减少图像数量。

选择重建方式取决于具体的病情和检查目的。

6. 对比剂:对比剂是一种用于增强CT图像对比度的物质。

常用的对比剂包括碘剂和钡剂,它们可以在某些病灶中突出显示出来。

在进行CT检查时,医生会根据需要使用适当的对比剂。

7. 剂量管理:CT扫描中的辐射剂量是一个重要的关注点。

医生和技师们需要确保以最低的辐射剂量获得足够的图像质量。

因此,合理的剂量管理对于保护患者的健康非常重要。

总结:掌握CT检查的参数知识点是理解和解读CT图像的基础。

在选择合适的扫描方式、层厚、峰值伏特数、重建方式和对比剂等参数时,需要综合考虑患者情况和检查目的。

User's GuideCable Tester and Digital MultimeterModel CT40CT40 V1.3 09/092 IntroductionCongratulations on your purchase of the Extech CT40. This meter is shipped fully tested and calibrated and, with proper use, will provide years of reliable service. The CT40 is a cable tester which uses a transmitter/receiver to allow for wire identification of an individual core to the end of a multi-core cable .The meter’s digital multimeter functions provides for easy measurement of AC/DC Voltage, AC/DC Current, Resistance, Continuity and Diode check.SafetyInternational Safety SymbolsThis symbol, adjacent to another symbol or terminal, indicates the user must refer to the manual for further information.This symbol, adjacent to a terminal, indicates that, under normal use, hazardous voltages may be presentDouble insulationSafety Notes• Do not exceed the maximum allowable input range of any function.• Set the function switch OFF when the meter is not in use.• Remove the battery if meter is to be stored for longer than 60 days.Warnings• Set function switch to the appropriate position before measuring.• Do not measure current on a circuit whose voltage exceeds 600V.• When changing ranges always disconnect the test leads from the circuit under test. Cautions• Improper use of this meter can cause damage, shock, injury or death. Read and understand this user manual before operating the meter.• Always remove the test leads before replacing the battery.• Inspect the condition of the test leads and the meter itself for any damage before operating the meter. Repair or replace any damage before use.• Use great care when making measurements if the voltages are greater than 25VAC rms or 35VDC. These voltages are considered a shock hazard.• Voltage checks on electrical outlets can be difficult and misleading because of the uncertainty of connection to the recessed electrical contacts. Other means should be used to ensure that the terminals are not "live".• If the equipment is used in a manner not specified by the manufacturer, the protectionprovided by the equipment may be impaired.CT40 V1.3 09/093 Meter Description1.Low Battery Indicator -Receiver 2.Receiver Alligator Test Leads 3.Operation Indicator -Receiver 4.On/Off Switch -Receiver 5.Hold Switch – Digital Multimeter Mode 6.DMM Input Jacks 7.Max Button – Digital Multimeter Mode 8.Mode Button – Digital Multimeter Mode 9.
