Neurolytics – AI‑Powered Neuro‑Oncology Assistant

---

Overview

More than 50 million people worldwide need MRI interpretation every year, yet neuroradiologists are scarce and expensive. Neurolytics lets anyone upload a brain MRI, receive an AI‑driven diagnostic summary, and ask follow‑up questions in natural language – all inside a single web page.

We combine Next.js, Google Gemini Vision, and AWS S3 to deliver expert‑level insights in seconds, freeing clinicians to focus on critical cases and empowering students to learn neuro‑oncology hands‑on.

What It Does

Step	Action	Tech
1	Upload any T1/T2 slice (JPEG/PNG)	Next.js file input
2	Instant Analysis of tumor type, grey‑matter loss, abnormalities	Gemini Vision 2.0
3	One‑Click Chat – ask anything about the scan with grounded answers	Gemini LLM + JSON context
4	Auto‑Archival – each run saved to S3 and visible in History tab	AWS S3

---

Key Innovations

• Context‑Grounded Chat – every reply cites the exact JSON analysis, avoiding hallucinations.
• Timestamp Keys – frontend & backend stay perfectly in‑sync even with concurrent uploads.
• Zero‑Sound UX – purely visual + textual; ideal for quiet clinical settings.
• Plug‑and‑Play Cloud – no GPUs needed; Gemini handles all computation.

1. /analyze_mri → uploads image, gets JSON analysis, stores to saved/<timestamp>/.
2. /chat → receives { prompt, timestamp }, loads matching JSON, returns answer.
3. /history → lists past runs with thumbnails & summaries.
