GE HealthCare's StarGuide GX Digital 4D CZT SPECT/CT Receives FDA 510(k) Clearance in the U.S.

GE HealthCare recently announced that its new digital 4D CZT SPECT/CT system, StarGuide GX, has received 510(k) clearance from the U.S. Food and Drug Administration (FDA). The system had previously obtained CE marking, and this U.S. clearance marks progress in the clinical adoption of its next-generation molecular imaging technology.

Designed for theragnostics and precision medicine needs, StarGuide GX is a comprehensive SPECT/CT system. It supports imaging at multiple energy levels, enables general-purpose SPECT imaging, and is tailored for emerging tracer applications, including investigational α-emitters, aiming to provide imaging support for clinicians and researchers exploring new pathways in diagnosis, treatment planning, and therapeutic response monitoring.

With the advancement of radiopharmaceutical therapies, interest in α-emitting isotopes within the nuclear medicine field continues to grow. As noted in the materials, α-emitting isotopes such as actinium-225 and lead-212 can be used for highly targeted cancer therapy, characterized by the release of high-energy radiation over short distances to minimize impact on surrounding healthy tissue. As such therapies expand, accurate imaging and quantitative analysis of α-emitters will support treatment planning, dosimetry, efficacy assessment, and related clinical research.

In terms of technical configuration, StarGuide GX incorporates GE HealthCare's proprietary dual-sided cadmium zinc telluride (CZT) detector technology, designed to enhance volumetric sensitivity while maintaining high-resolution imaging capabilities, helping clinicians acquire more imaging information within shorter scan times. The system also integrates NVIDIA RTX computing technology to optimize image reconstruction and accelerate result generation.

Additionally, the system is equipped with proprietary dual-collimator detectors that enable collimator exchange within three seconds, designed to streamline traditional collimator change procedures and improve workflow efficiency in nuclear medicine departments. Its automated collimator exchange design also helps reduce the need for multiple collimators, carts, and associated storage space.

GE HealthCare stated that StarGuide GX is designed as an integrated system supporting advanced imaging technologies and emerging tracers, with the goal of helping clinicians expand molecular imaging capabilities and advance the development of theragnostics and personalized medicine.
