Lucas Brito, PhD

Clinical Medical Physicist & Software Developer · Based in Rio de Janeiro 🇧🇷

I work at the intersection of clinical radiotherapy and software engineering — building open-source tools that close the gap between treatment planning systems and the clinical reality around them.

What I'm building now

🔹 patient-plan-explainer — Turns DICOM RT treatment plans into patient-friendly explanations. PDF + audio, Brazilian Portuguese.

🔹 eclipse-dicom-fix — Re-encodes compressed DICOM files (JPEG Lossless, JPEG 2000) to Implicit VR Little Endian for clean Eclipse TPS import.

🔹 dicom-rt-explained — A practical, code-first guide to DICOM-RT for developers entering radiation oncology. Bilingual (EN / PT-BR).

🔹 Radioterapia.AI (private) — AI-powered clinical platform for radiation oncology workflows. Co-founded with Dr. Henrique Braga.

Day job

Clinical Medical Physicist & Radiation Protection Supervisor at Oncobarra (Rio de Janeiro). Daily work spans Varian Eclipse / ARIA, IMRT, VMAT, DIBH, 3D-CRT, and HDR gynecological brachytherapy.

Previously: supervising physicist during the installation of a Varian Halcyon with HyperSight at Hospital de Saúde da Mulher (Belém), and clinical roles at Oncoclínicas (Latin America's largest oncology network) and others.

Background

  • PhD in Physics — Centro Brasileiro de Pesquisas Físicas (CBPF), 2015
    • Doctoral research within the CMS Collaboration, CERN
  • CNEN-certified Radiation Protection Supervisor (Radiotherapy)
  • CNEN-certified Medical Physics Specialist (Radiotherapy)
  • 6+ years of clinical practice across four Brazilian radiation oncology services

Tech I work with

Clinical: Eclipse · ARIA · ESAPI · PDSAPI · DICOM-RT

Languages: Python · JavaScript · TypeScript · C#

Libraries / Frameworks: pydicom · React · Three.js · Streamlit · FastAPI · WeasyPrint · ReportLab

Infra: Cloudflare Pages / Workers · D1 · Git · GitHub Actions

AI: Anthropic Claude API · Google Gemini API · LLM integration in clinical workflows

Get in touch

I'm always open to conversations about medical physics + software, especially:

  • DICOM-RT processing and validation
  • Clinical workflow automation
  • AI applied to radiation oncology
  • Open-source tooling for cancer care

This profile reflects my open-source / public work. The intersection of clinical practice and software development is where I keep finding the most interesting problems.
