For researchers · PULSE on the US PRO 2000

Programmable
ultrasound,
in one hand.

PULSE turns the US PRO 2000, a handheld 1 MHz ultrasound, into an instrument you program from a phone. Pick a pulse program from a signed library, load it in seconds over NFC, and run timed sessions at three intensities. For a study, we build the program with you.

01 · THE SYSTEM

Four parts, one loop.

A program goes from your account to the phone, over NFC into PULSE, and PULSE programs the ultrasound. Here is each part, in the order a program travels.

The UltraNFC app's Library on an iPhone
01 · LIBRARY

Signed pulse programs.

39 programs in the library today. Each is a firmware image signed by UltraDAO and checked on the device before it runs.

02 · ULTRANFC APP

Load it from a phone.

The UltraNFC app for iPhone and Android holds your library. Hold the phone to the POWER switch and the program goes over NFC; the app reads it back to confirm.

03 · PULSE MODULE

The board inside.

Under the front panel: a PN7150 NFC front end, W25Q64 flash and an RP2040 that programs the instrument. Six spring pins connect it; nothing is soldered.

04 · US PRO 2000

The instrument.

A Ø24 mm piezo transducer at 1 MHz, 0.08–1.6 W/cm² in steps, about 40 mm effective depth in soft tissue. MODE sets the intensity, TIME a 5, 10 or 15 minute session.

02 · PROGRAMMABLE

Change the protocol in seconds.

Switching protocols means loading a different program, not re-cabling a rig. These are the families in the library right now.

03 · REPEATABLE

The same program, every session.

Checked on the way in.

A program is written to flash and checked against keys provisioned by UltraDAO. A bad signature never lands.

Read back after.

After each load the app reads the program back from the device and only then says Installed and verified.

Timed on the device.

Sessions are set on the device itself (5, 10 or 15 minutes) and counted down on its lights.

04 · COMPARED

A handheld, not a rig.

Programmable pulsed ultrasound usually means a research system costing $10,000 or more, or a signal chain built on a bench. In many cases, PULSE matches them in one hand.

05 · SMALL ANIMALS

Working with mice.

Mind the size of the face.

The transducer face is 24 mm across, wider than a mouse’s head, so a session covers a broad area rather than one structure. Plan positioning and coupling with that in mind.

Your approvals.

Animal work is subject to your institution’s animal-care approvals (IACUC or equivalent). PULSE is sold for research and development use only; it is not a medical device and not FDA cleared.

Tell us what you are planning, and we work out the program and the setup with you as part of your research package.

06 · BUILT WITH YOU

Research packages are custom.

A study is more than a device. We scope each research package with you: the programs your protocol needs, the hardware, and the support to run it.

Your idea.

What you want to study, and the questions you want answered.

Your programs.

We build and sign the pulse programs your protocol calls for, alongside the library.

Your package.

Hardware, programs and support, put together for your study and quoted for it.
