MRI training simulator · browser-based · brain v1

Scan a brain before you ever touch a scanner.

Zlado Scan is a virtual MRI console that runs on your own laptop. Plan slices on localizers, set TR, TE, flip angle and matrix like a real Siemens or GE console — and get an image that is computed from the physics, not pulled from a folder of pictures.

No card needed · Brain routine protocol included · a fixed number of scans, counted on screen

Every move re-samples k-space and reconstructs the image with a Fourier transform. That is what the real console does too.
Preview model. The full console uses a segmented real brain scan and a research-grade simulation engine.

Nothing is pre-rendered

Change any parameter — TE, TR, slice thickness, flip angle, bandwidth — and the image changes the way physics says it must. Wrong choices look wrong.

1laptop

No scanner slot needed

Runs in the browser with an individual login. Practise at midnight, repeat a sequence twenty times, break nothing.

The brain routine, as run in a department

Localizer, MPRAGE, DWI, SWI, T2, FLAIR, T1 and a coronal — defined by MRI faculty who teach it every week at Zlado.

How it works

The same four moves as the real console

We copied the workflow, not just the look. If you can run an exam in Zlado Scan, the console in the department will feel familiar.

Start from Brain routine or build your own from a library of sequences — each with its Siemens, GE and Philips names.

Plan on the localizers

Drag the yellow slice group across sagittal and coronal views. Slices, thickness and gap update the coverage as you go.

Scan and look

Watch k-space fill line by line, then window the image, step through slices and compare against your previous run.

Version 1 · brain

What you scan, and what each sequence teaches

One anatomy, done properly. The phantom is built from a real segmented brain scan, so what you see behaves like tissue, not like a cartoon.

Access

Two ways in

Buy it on its own, or get it bundled with the Zlado course you are already doing. Either way it is a subscription with a clear end date.

Path A · self-serve

Subscribe directly

Anyone can sign up on this site and start scanning today — students in a radiography programme, technologists preparing for a licensing exam, teachers who want a demonstration tool.

  • Monthly or yearly, cancel any time
  • Full brain routine and the sequence library
  • Your saved sequences and results stay with your login
Path B · bundled with a Zlado course

Included when you enrol

Enrol in a related course — MRI Foundation, for example — and simulator access is switched on the moment your enrolment is confirmed. No form, no waiting for staff.

  • Its own validity, typically one or two months, matched to the course
  • Scoped to the sequences the course actually teaches
  • Switches off automatically when the period ends — extend by subscribing
Free trial

Seven days. A fixed number of scans. The whole brain routine.

You get the real console, not a video of it. The counter is always on screen so you can spend your scans on the sequences you want to understand.

Talk to us

Course-bundled access (Path B) has no separate price — it is part of the course fee for the courses that include it.

Assessment

Practise unscored. Finish with a real exam.

Day-to-day practice is not graded — you are supposed to make mistakes there. The certificate is earned at the end, by two gates.

Gate 1

MCQ exam

Physics and protocol questions written by Zlado's MRI faculty: what changes when TR halves, why FLAIR needs a long TR, how to read a SAR warning.

Gate 2

Hands-on scan exam

A timed exam on the simulator itself: plan and run a set protocol on a case you have not seen, within scan-time and coverage limits. The images you produce are what gets assessed.

Clear both and you receive a Zlado Scan completion certificate, dated and verifiable, listing the protocol you were examined on.

What it does not do — yet

A simulator earns trust by being honest about its edges. These are ours in version 1.

Slices no thinner than the source

The phantom comes from a real scan acquired at 3 mm (1 mm for FLAIR). Ask for 1 mm slices on a 3 mm source and you get an interpolation, not new detail — and the console tells you so.

Normal anatomy only

Version 1 is one healthy adult brain. Stroke, tumour and other pathology datasets are the first expansion after launch.

1.5 T, head coil

Field strength and coil are fixed in v1. Sequences that need flow, steady-state or partial-Fourier physics (TOF, TrueFISP, HASTE) are listed in the library but locked until the engine supports them.

FAQ

Questions we get from students

Do I need a powerful laptop?
No. The console runs in a modern browser; the simulation itself runs on Zlado's servers. A normal laptop and a stable connection are enough. Tablets work for reviewing images but the parameter card is designed for a keyboard.
Is this the same as a Siemens or GE console?
It is modelled on them — the exam queue, three planning viewports, the parameter card with Routine / Contrast / Resolution / Geometry tabs, and the TA / voxel / SNR / SAR readout. Vendor names differ, so every sequence in the library shows what Siemens, GE, Philips and Canon call it.
What happens when my trial ends?
Your login stays, your saved sequences and images stay, but the Scan button is locked until you subscribe or a course bundle switches access back on. Nothing is deleted.
I'm enrolled in a Zlado course. Do I still need to pay?
If your course includes simulator access it is switched on automatically when you enrol, for the period the course defines. If you want to keep scanning after that period, or use sequences outside the course scope, you subscribe directly.
Is the image really computed, or is it a stored picture?
Computed. The phantom stores T1, T2 and proton density for every voxel; the engine simulates the acquisition into k-space for the parameters you chose and reconstructs the image with a Fourier transform. That is why a wrong TI on FLAIR leaves CSF bright instead of showing you a pretty picture anyway.
Who validates that the images look right?
Zlado's MRI faculty review simulated output against real departmental images as part of development. Where the simulator cannot match reality — see the limits above — the console says so rather than pretending.
