2025年2月11日 · Interstitial lung disease (ILD) is an umbrella term that encompasses a large number of disorders that are characterized by diffuse cellular infiltrates in a periacinar location. The spectrum of conditions included is broad, ranging from occasional self-limited inflammatory processes to severe debilitating fibrosis of the lungs.

2022年6月8日 · 目前，idl 在医学图像处理中的应用已非常广泛，它可以快速、容易地实现对各种医学图像的处理。 例如，IDL可以处理X-ray图像、MR和CT图像、PET 图像、DSA图像以及分子生物学中的显微医学图像等。

2020年11月4日 · CT (Computed Tomography)，即电子计算机断层扫描，它是用X射线束对人体某部一定厚度的层面进行扫描，由探测器接收透过该层面的X射线，转变为可见光后，由光电转换变为电信号，再经模拟/数字转换器转为数字，输入计算机处理。 而图像形成的处理有如对选定层面分成若干个体积相同的长方体，称之为 体素（voxel），体素的概念类似于图像中的像素，只不过它是用来显示3D的图像，它包含z方向上的大小，即厚度。 扫描所得信息经计算而获得每个体 …

When ILAs are detected, a dedicated chest CT examination could help to confirm and characterise the abnormality, especially if dependent atelectasis was present, if the initial scan of the lungs was incomplete (eg, an abdominal CT), or if the scan was done without thin sections, with an ultra-low dose technique, or using first-generation ...

ILD can be seen in all CTDs but most commonly in rheumatoid arthritis (RA), systemic sclerosis (SSc), and idiopathic inflammatory myopathy (IIM). This primer will focus on the general features of CTD-ILDs along with distinct features noted in RA, SSc, and IIM-associated ILD.

2024年5月2日 · IDL，全称为交互式数据语言，是一种专门用于数据分析、可视化及应用程序开发的编程语言。它广泛应用于天文学、遥感、医学影像分析等科学研究领域。与其他编程语言相比，IDL特别设计用于处理和可视化大量数据，提供了大量的数学、统计和图形绘制功能 ...

UCSF ILD Program Protocol for High-Resolution CT Scanning of the Chest Axial Scans in both prone and supine positions suPIne ImagIng: • 1–1.5 mm collimation at 2 cm intervals in full inspiration. • Measure field of view • High spatial frequency reconstruction algorithm (can use bone algorithm on GE machine) • Full inspiration • Window:

Interstitial lung disease (ILD) including idiopathic pulmonary fibrosis increases the risk of developing lung cancer. Diagnosing and staging lung cancer in patients with ILD is challenging and requires careful interpretation of computed tomography (CT) and fluorodeoxyglucose PET/CT to distinguish no …

本篇博客介绍一些有关于ct图像的基本知识和概念，然后通过idl语言来显示ct图像。 用 IDL 语言 读取 并操作 图像 数据 04-04

Our software, called CoBRA, is a portable cone beam reconstruction code for CT applications that efficiently and rapidly reconstructs large data sets. CoBRA applications include both x-ray and neutron inspections using x-ray phosphor screens coupled to either a CCD camera or flat-panel amorphous silicon arrays.
