Precision software
for radiopharmaceutical
therapy.

RadFox is building modern software for absorbed dose verification, imaging analytics, and workflow intelligence in radiopharmaceutical therapy — designed for where the field is going, not where it was.

Why now

Radiopharmaceutical therapy is entering its measurable era.

RPT is moving from fixed-activity regimens toward personalized, evidence-based care — but the software infrastructure to support it has lagged behind the science.

Projected growth in Lu-177 and alpha-emitter RPT programs at academic centers through 2028.

THE GAP

There is a gap between scientific sophistication and operationally usable software.

Dosimetry is powerful, but fragmented across vendor tools, spreadsheets, and manual contouring. Post-therapy dose verification — the most practical clinical entry point — remains under-implemented because the workflow doesn't yet exist at production grade.

RadFox is building that workflow.

The platform

Five pillars. One coherent system.

RadFox is designed as an integrated platform for radiopharmaceutical therapy programs — not a collection of point tools stitched together.

01 / DOSE

Absorbed dose verification

Patient-specific, post-therapy dose calculation with organ- and lesion-level reporting — the practical clinical entry point for scaled dosimetry.

02 / IMAGING

Imaging analytics

SPECT/CT and PET/CT ingestion, harmonization, and quantification — built for the heterogeneity of real-world multi-site protocols.

Learn more →
03 / AI

AI-assisted review

Segmentation assistance, structured summarization, and review acceleration — as copilots for trained clinical staff, not replacements.

Learn more →
04 / WORKFLOW

Clinical workflow intelligence

Case routing, review states, and auditability — treating the RPT program as a coordinated clinical workflow, not a sequence of disconnected studies.

Learn more →
05 / LONGITUDINAL

Longitudinal insight

Cycle-over-cycle dose and response tracking — the evidence infrastructure RPT needs to move toward individualized treatment.

Learn more →
06 / REPORTING

Structured reporting

Clinically literate, exportable reports that fit how nuclear medicine teams actually document, review, and hand off cases.

— RadFox operating principle №1
Built by

A team grounded in advanced oncology systems.

RadFox is being built by engineering leaders from the intersection of medical device software, imaging-driven therapy workflows, and regulated clinical systems.

Real experience in treatment systems

Founded by an engineering leader with deep background in advanced oncology and radiation treatment platforms — not a generalist entering a new field.

Designed for regulated environments

Built with the operational realities of regulated medical software in mind from day one — quality, auditability, and clinical seriousness as defaults.

Informed by where RPT is going

Shaped by the field's movement toward personalized dosimetry, dosage optimization, and evidence infrastructure for individualized radiopharmaceutical care.

Systems thinking, not demos

We are building a coherent platform — the kind of software infrastructure that takes time, technical depth, and real clinical partnership to get right.

Connect

For clinical and strategic partners.

RadFox is in active conversations with academic cancer centers, nuclear medicine programs, radiopharma developers, and clinical advisors. If that's you, we'd like to talk.
