## TL;DR

Empyrean Medical Systems, of Florida, develops radiotherapy machines that use magnetic fields to shape high-energy electron beams, an MD Anderson approach designed for both conventional and FLASH dose rates, plus Vektra, a robotic arm for delivering radiation during surgery. None of its patient-treatment devices is yet cleared for sale.

## Summary

Empyrean Medical Systems develops radiotherapy devices built around MOVHEET, an approach from MD Anderson Cancer Center researchers that uses magnetic fields to sculpt high-energy electron beams and is designed for both conventional and FLASH dose rates. In 2022 the company acquired Vektra, a robotically assisted 50 to 120 kV platform for brachytherapy and intraoperative radiotherapy described as FLASH capable; it is not for sale and is pending FDA 510(k) clearance. Its first shipped product, Artemis 320, is a preclinical cabinet x-ray irradiator intended to replace caesium irradiators, with a first US installation announced in June 2026. In January 2026 Hamilton Reserve Bank took an equity stake and agreed to arrange a credit line of up to USD 20 million; the release states MD Anderson owns 15 percent and Mayo Clinic is also a shareholder.

- The domain empyreanmedicalsystems.com does not resolve; the company's live site is empyreanmed.com (as given in its press releases). Equity amount from Hamilton Reserve Bank was not disclosed and the USD 20 million credit line was 'to be arranged', so no amountUsd is recorded. Founding year and any venture rounds are unsourced. No clinical device has FDA clearance as of the fetched pages.
