4DMedical Gains TGA Approval for CT:VQ Lung Imaging in Australia

Jun 29, 2026
4DMedical has received approval from the Australian Therapeutic Goods Administration for its CT:VQ imaging technology, enabling contrast-free ventilation and perfusion imaging using standard chest CT scans.

4DMedical has received approval from the Australian Therapeutic Goods Administration for its CT:VQ imaging technology, according to a press release. The company will introduce the software in Australia, enabling ventilation and perfusion imaging without the use of contrast agents.

CT:VQ generates ventilation and perfusion data directly from routine non-contrast chest CT scans. The technology provides a software-based option that integrates with existing CT infrastructure, expanding access to functional lung assessment.

The TGA approval follows CT:VQ’s clearance by the U.S. Food and Drug Administration in 2025, where it has been deployed in leading medical institutions.

Tensordyne Napier: What If One Rack Could Do the Work of Nine?

Tensordyne

This Tensordyne whitepaper presents Napier, an inference-focused AI processor and rack-scale system based on the company’s TDN Math logarithmic number system. It examines infrastructure requirements for large mixture-of-experts and agentic models, compares major inference architecture approaches, and details the TDN AIP processor, TDN72 pod, TDN Link fabric, and Napier Ultra configuration. The paper reports simulation-based performance, cost, and accuracy-validation results, including Tensordyne’s projected comparison of one Napier rack with a nine-rack Nvidia Rubin plus Groq deployment; the chip is reported as taped out and in fabrication.
