Good stuff!

Now that you have a 3Dicom account and seamlessly downloaded the software through the Singular Launcher, it is now time to load in your first medical scan into the dicom viewer. If you have not created a My Singular Health account to operate 3Dicom, you can view the informative article 這裡. We also strongly recommend you also check out our previous article on how to download the 3Dicom dicom viewer through the Singular Launcher. You can also read the article 這裡.

Now you have all the tools to begin your medical image analysis, let’s begin.

DICOM 掃描具有很高的可訪問性,可以從互聯網上的多個來源下載。 3Dicom 還為您提供完全的可訪問性,將您自己的個人 DICOM 文件上傳到軟件中。如果您無法訪問從醫療或教育機構甚至醫生等地方提供給您的 DICOM 文件或 DICOM 圖像,我們可以從許多其他位置下載 DICOM 掃描。

1. 下載您的 DICOM 掃描

The 3Dicom website has provided you with a number of scans which you can download onto your device for FREE. Yes, for free. These scans can be accessed via the DICOM Library in the ‘Support’ tab, or can be accessed 這裡.

DICOM 掃描也可以從許多開源存儲庫中下載,例如 癌症影像檔案 (TCIA), 美國國家生物醫學成像與生物工程研究所 (NIH) 或者 哈佛大學數據宇宙. Other sources associated with radiology and medical imaging also may provide you with a dicom image file. These resources provide you with a number of DICOM studies that are downloadable; both free and paid accommpanied by the DICOM metadata, different series and the scan itself. These will typically be a CT scan, MRI scan or a PET scan.

For ease of accessibility, we will be using the ‘Covid19 CT Dicom Image’ found in the DICOM Library on the 3Dicom website.

訪問 DICOM 庫後,我們需要選擇下載掃描。使用您選擇的 DICOM 掃描將我們定向到文件後,我們需要在左上角選擇下載。

Please be mindful of the download time. Each scan differs in size and complexity, so please be patient if your scan is taking a while to download. Downloads will be typically be placed on your computers desktop, downloads file or OneDrive.

Sometimes when your dicom image file is downloaded, the different images will not be in a dicom format (.dcm) and instead a different image format such as .psd, .jpeg or .png. When we unzip the file, this will typically convert the file format to a DICOM file format.

If you have designated a specific location on your device as to where downloads will be located, note where this is!

Unzipping a file on Windows

Once our scan has been downloaded on Windows, we will typically have to extract the file if it is downloaded as a ZIP file or file extension. This is just a way of your computer compressing the size of the dicom data and file contents, due to the large size of the dicom medical images. If you are having difficulty extracting your scan file, we have provided a video below to guide you through the process.

Firstly, we will have to locate the downloaded scan. Once we have located the file, we will need to extract the contents. Simply right click on the file and select ‘Extract All’. This will unzip all the contents in the file to a specific location. If you are still having trouble extracting the contents, this article will guide you through the simple process.

2.通過Singular Launcher打開3Dicom

下載 DICOM 掃描後,現在我們必須打開 dicom 軟件,否則我們無法以 3D 形式可視化我們的掃描!如果這是您第一次打開 3Dicom,請記住它是通過 Singular Launcher 打開的。 Singular Launcher 是我們通往 3Dicom 的門戶!

3. 導入您的掃描

Your last step in viewing your scan is importing the dicom file into 3Dicom. This step is very simple and we have made this process as seamless as possible. The only thing you need to remember is where you saved the file that was downloaded and, then extracted (if applicable).

First, we need to select the ‘Import Dicom’ button in the top right. Once this is selected, a drop down window will appear displaying all of your computers folders and file locations. This is why remembering where you saved your scan file is important!

找到掃描文件夾後,只需單擊它並按確定。根據您的掃描大小和切片數量,dicom 查看器中的圖像處理時間會有所不同,但是此過程非常快速且高效。您可能還有不同的系列可供選擇。選擇掃描後,這些將位於系列選項卡中。

Now you have successfully imported your first ever DICOM scan. Easy right?

如果您在加載掃描時遇到問題(這種情況很少見),請確保您下載的掃描沒有損壞或過期。加載的掃描也必須在導入 dicom 軟件之前解壓縮。

如果您仍然無法加載掃描,請 在此處提交支持票。
