What you'll see
Your scan opens slice by slice, with its series or planes beside it, what the scanner says in its corners and the patient's sides at its edges.
- Every series in order through the body • The wheel steps through it
- Window and level • Drag it, or pick CT's presets
- Measure lengths, angles and areas in millimeters
- Export • PNG, JPEG, MP4, or the files without patient data
About DICOM
DICOM has carried medical images since 1993, when the American College of Radiology and NEMA made it so any scanner could talk to any viewer. Every CT, MRI, X-ray, mammogram and ultrasound is kept and sent in it, and the CD a patient takes home holds a folder of DICOM files with a DICOMDIR that lists them.
A DICOM file holds an image, or a loop of frames, with tags about the patient, the study, the series and the scanner. Its pixels can be plain or packed with JPEG, JPEG Lossless, JPEG-LS, JPEG 2000, RLE or JPEG XL, in 8 to 16 bits or more. Some files hold no picture at all: a report, an ECG, or a PDF kept inside.
Filepeek reads them in your browser. Drop a file, a folder or a study's CD, and it sorts the images into series in their order through the body, shows them with the scanner's window and level or CT's presets, and steps through the slices with the wheel or the arrow keys. Measure lengths, angles and areas in millimeters, read every tag, and save an image as PNG or JPEG, a series as MP4, or the files without patient data. It's for looking at your images, not for diagnosis.

Questions
How do I open the scans on my CD?
Drop the CD's folder on this page, or open its DICOMDIR with the files beside it. Filepeek lists every study and series it finds, each in order.
Can I scroll through a whole series?
Yes. Drop the folder with all its files. Images are grouped into series and sorted through the body, and the wheel, the arrow keys or the slider step through them.
Can I measure?
Yes. Choose Measure, then Length, Angle or Ellipse. Lengths and areas are in millimeters, and an ellipse gives the mean of what's inside it, in Hounsfield units on CT.
Can I share a scan without my name in it?
Yes. Choose Export, then Save without patient data. The files are written again with names, IDs, dates and other details taken out, as DICOM's own profile for it says. Text burned into a picture stays, and Filepeek says so when a file has some.
Is it for diagnosis?
No. Filepeek shows your images so you can look at them. Doctors read scans with approved software on calibrated screens.
Is my scan uploaded?
No. Every file is read inside your browser, and nothing is sent anywhere.
