Patient CD/DVD/USB DICOM Viewer

We offer a MicroDicom DICOM Viewer CD/DVD/USB version. This autorun package can be burned together with DICOM images on CD/DVD/USB or other external storage. Our software runs from CD/DVD on other computers without installation. Users can insert a CD and Autorun will start our viewer and show images stored on the CD. It is ideal for patient CDs/DVDs, allowing users to view DICOM images without installation.

Multiplanar reconstructions

The MPR available in MicroDicom DICOM viewer enables users to reconstruct images in various planes, including coronal, sagittal, axial, or oblique, depending on the orientation of the base images. This allows for a more comprehensive visualization of anatomical structures and enhances the diagnostic capabilities.

 

3D Volume Rendering

The 3D Volume Render tool lets you visualize entire CT and MR series as a single, solid three-dimensional object — instead of paging through slices one by one. The volume can be freely rotated and zoomed with the mouse, giving you an intuitive, real-time view of complex anatomy from any angle. The image is rendered progressively, so the view stays smooth and responsive while you interact, then automatically sharpens to full detail the moment you stop — even on modest hardware, and with automatic GPU acceleration where available.

 

Image Fusion

Image fusion (PET-CT, PET-MR) is the process of combining information from two medical images into a single, more informative image. This allows you to combine functional imaging (e.g., PET) with anatomical imaging (CT/MRI) to localize metabolic activity.

 

Local database

The local database functionality enables the import of DICOM studies from various sources such as CD/DVD discs, USB flash drives, local and network folders, allowing you to store these studies directly on your local hard drive for easy future access. Additionally, you can utilize the database to organize and swiftly locate studies within your collection of DICOM files stored on the hard drive.
Each study can be assigned a status to track its progress through the review and reporting workflow. The following statuses are available: Unread, In Progress, Reviewed, Urgent / STAT (highlighted in red), On Hold, Second Opinion, Dictated, and Signed.

 

Split the screen for comparing different DICOM images

Series from different studies or examinations can be compared in our viewer. Images can be displayed side by side by splitting the view. You can compare images from the same or different series. The images are synchronized by zoom and pan, slice position, and windowing. Cross-reference lines are used to identify the relative anatomical position. Scout or reference lines indicate the position and width of each cross-sectional image.

 

Search and download DICOM images from PACS

You can use MicroDicom DICOM viewer as a PACS (Picture Archiving and communication system) client. Our viewer can easily query, retrieve, and send images using the following DICOM and DICOMweb protocols: C-ECHO, C-FIND, C-MOVE, C-GET, C-STORE, QIDO-RS, WADO-RS, and STOW-RS . It also allows you to send DICOM images to PACS servers or other computers. Our DICOM viewer fully supports DICOMweb for modern, web-based medical image retrieval and display.

 

Supported DICOM files

MicroDicom DICOM Viewer can open studies produced by different medical equipment.

• Compressed and uncompressed RLE, JPEG Lossy, JPEG Lossless, JPEG2000 Lossy, JPEG2000 Lossless compressions
• Structured Reports, MPEG-2 and MPEG-4 transfer syntaxes, Encapsulated PDF
• Supports medical images produced by different medical equipment: CT, MRI, US, XA, CR, DX, PET-CT, …

 

Print DICOM images on a standard printer

You can easily print DICOM images with MicroDicom. You can choose images from a series, how many images per page and print. Also, you can hide sensitive information from the images before printing, such as the patient's name, age, etc.
