Ultrasound files come in different forms
Ultrasound is unique among medical imaging because it produces both still images and short video clips. Your scan might be: a handful of still images saved as DICOM, a series of short video clips (multi-frame DICOM), or a combination of both.
OpenMyScan reads all three forms. Drop your folder and the viewer figures out what's inside — single frames or playable clips.
Unlike CT or MRI, ultrasound doesn't use radiation. It's the standard tool for prenatal monitoring, abdominal exams, and cardiac assessment, and it's frequently used in emergency rooms because it's fast and portable.
Common ultrasound types
If your scan is in DICOM format, OpenMyScan can open it — regardless of body part or scanner brand.
-
Pregnancy ultrasound
Foetal development, growth, anatomy scans. The most emotionally significant ultrasound for many patients.
-
Abdominal ultrasound
Liver, kidneys, gallbladder, pancreas. Used for abdominal pain investigation.
-
Cardiac ultrasound (echocardiogram)
Heart structure and blood flow. The standard exam for assessing heart valves and chambers.
-
Vascular ultrasound
Blood vessels, blood flow, blockages. Used for suspected DVT, peripheral vascular disease.
-
Pelvic ultrasound
Uterus, ovaries, prostate, bladder. Used in gynaecology and urology.
How multi-frame ultrasound clips work
When your hospital hands you an ultrasound on a CD or USB, what you usually receive isn't a single image — it's a series of short video clips. Ultrasound is recorded live: the technician moves the probe across your skin while the scanner saves frames continuously. Each "scene" worth keeping ends up as a multi-frame DICOM file.
A multi-frame DICOM is one file that contains many frames, packed in order, with a frame-rate header. Think of it as a tiny video wrapped in DICOM metadata. OpenMyScan reads the header, plays the frames at the recorded rate, and lets you scrub through them one frame at a time. That's different from MRI or CT, where each "slice" is a separate file showing a different cross-section through stationary anatomy.
Frame rate matters because clinical ultrasound covers very different speeds. A pregnancy anatomy clip might run at 15–30 frames per second over a few seconds, capturing the baby moving. A cardiac echo (echocardiogram) records the heart's motion — typically 30–60 frames per second — so a single clip of a few seconds shows several full heartbeats. Vascular and abdominal clips are usually slower, because the technician is sweeping the probe rather than chasing motion.
Playing a clip at full speed shows you the moment as it was recorded — useful for seeing motion (a baby kicking, a heart valve opening). Scrubbing frame-by-frame is useful for stopping at the still images radiologists actually use to make measurements. Both modes are available in OpenMyScan: press play for cine, or use the slider to step through frames one at a time. The clip stays on your device; nothing about your scan is uploaded.
Viewing pregnancy ultrasound clips
Many parents want to keep and re-watch their pregnancy ultrasound clips at home. The clips your hospital gave you are usually multi-frame DICOM files — playable as short videos.
OpenMyScan plays these clips automatically. You can pause, scrub, and zoom. This is one of the most common reasons patients use a DICOM viewer at home: to share scan moments with family who weren't at the appointment.
The files stay on your device. They aren't uploaded anywhere. That matters — pregnancy scans are personal, and we think the choice of who sees them should be yours.
Questions people actually ask
Can I view my baby's ultrasound clip?
Yes. Multi-frame ultrasound DICOMs play as videos in the viewer. Drop the folder and find the clip in the series list.
Why does my ultrasound look grainy?
Ultrasound images are inherently grainy — that's how the technology works (sound waves bouncing off tissue). The graininess isn't a viewer problem.
Can I save the ultrasound video to share?
You can save individual frames as images. Full-clip MP4 export isn't available yet — for now, a screen recorder is the simplest path.
What's the difference between 2D and 3D/4D ultrasound?
2D shows a single cross-section. 3D builds a static surface model. 4D is a 3D model that moves over time. Most clinical ultrasounds are 2D; 3D/4D is sometimes used for keepsake imaging during pregnancy. OpenMyScan plays whichever format your hospital exported.
Can OpenMyScan tell me if my baby is healthy?
No. OpenMyScan is a viewer, not a diagnostic tool. Always discuss your ultrasound results with your doctor or sonographer.
How do I tell which clip is which?
Each clip in the series list is labelled by the scanner — sometimes cryptically. Click through them to find what you're looking for.
