RadCase: the hidden bits

Fourteen years of shortcuts, secrets and one very long June weekend.

Easter eggs

Four secrets hidden in RadCase for years. Each one below is a working replica — go find them.

01
God mode · 2016

Type the magic word

RadCase

Type kingme into the Accession box and the window grows, revealing a row of hidden green debug buttons. Watch closely: the moment you type a “k”, the box starts hiding what you type, so nobody looking over your shoulder sees the password.

02
Hidden note · 2016

A message only an auditor would find

RadCase.exe — decompiled
string msgForAgfa = 

Never shown on screen. The only way to find it is to take the program apart — which is exactly what an auditor would do.

03
Rare sighting

“We have a live one!”

If IMPAX ever sends RadCase its launch application signal, RadCase answers with this. It has been wired up all along and is almost never seen.

04
Error message · 2016

Boom!

When Win+H can’t paste the clinical history, the apology comes with a word from our sponsor: the full error report.

Bonus level PACS DOWN! The game from the night the site went dark. Dodge the “quick questions”, dictate through the garble, top the leaderboard. Play →

Keyboard shortcuts

All shortcuts work from anywhere while RadCase is running in the tray.

KeysWhat it does
Win+X
Win+C
Win+Shift+X
Search. Refreshes the current patient, then resets the IMPAX search and fills in the patient’s name and date of birth so every study they’ve had comes up. Long names that IMPAX cuts off with “…” become a wildcard; middle names are dropped because sites record them inconsistently. Win+C and Win+Shift+X were added in 2026 because Windows 10/11 keep Win+X for their own menu.
Win+Shift+C Tag current case. Captures the study on screen (user, site, accession) and pops RadCase up so you can mark it Teaching, Follow Up, Procedure, QA or Private, add a diagnosis and keywords, and submit. This was Win+C until 2026.
Win+H Clinical history. Pulls the indication from IMPAX (skipping the allergy information, keeping multiple lines) and pastes it straight into your dictation. Added July 2013 for the inpatient work at St. Boniface.
Win+W Comparison. Pastes the comparison study’s date into your report, e.g. “October 1, 2016” — and adds the hospital, e.g. “(St. Boniface General Hospital)”, when the comparison was done somewhere else. Added May 2016 (it started life as the laptop key).
Win+N Back to New. Sets the current study’s status back to New. One of the first features, June 2012.
Win+Z Trainee click-off. For staff reviewing a trainee’s work: marks the current study as trainee-dictated and then closes off everything in the current display.
Win+S Capture key image number never released
Grabs the series and image number of the current key image and puts it on the clipboard, ready to paste as “(series 3, image 42)”. It stayed in the build but was never released publicly, despite months of testing, because it was unreliable (see Mitra below).
Click the Accession box Copies the accession; with several accessions, a single click copies just the first one.
Double-click the Accession box Copies everything in the box.

Why key image capture never shipped

The root cause was the Mitra Context Server (mitra_context_server), the intermediary that lets outside programs talk to IMPAX. It took one entire, beautiful June weekend to figure it out: the context server itself was fragile and would work a few times before crashing.

Fun fact

Mitra was essentially the software engine behind IMPAX for most of its first decade. Agfa sold and branded the product, but Mitra, a company in Waterloo, Ontario, wrote much of the code.

After 2002. The Mitra brand was absorbed into Agfa HealthCare over the following years. Waterloo became one of Agfa HealthCare’s main R&D centres, and IMPAX 6 was developed largely there. The IMPAX line later fed into Agfa’s Enterprise Imaging platform. So the Waterloo engineering base that started as Mitra stayed central to the product long after the name disappeared. If you go through file listings and crash logs, Mitra is usually there!

The build log, 2009–2026

Pieced together from the dated comments in the RadCase source code.

  1. Prologue
  2. 2009
    Residency begins.
  3. 2010
    First year of radiology residency.
  4. Before 2012
    Code from two earlier projects — HookTorcha, and OnCall (a separate app entirely) — is carried forward into the IMPAX library RadCase would grow out of.
  5. 2011–12
    A year of OCR. A project called Satellite tries to read IMPAX off the screen with home-made character recognition so studies can be searched and tagged.
  6. May 31, 2012
    First entry in the development log: patient number and accession fields, a user picker.
  7. June 2012
    Teaching-file submission, hospital proxy support, and Win+N “back to New” — much of it written on Sunday nights.
  8. The roots
  9. Nov 15, 2012
    The Mitra Context Server is discovered and the OCR is retired — glitchy at best, completely unreliable at worst. This is where RadCase really begins.
