# Major Recall Alert: Catalyst HD, Catalyst+ HD Systems Risk Erroneous Dose Delivery
C-RAD has announced an urgent recall of its Catalyst HD and Catalyst+ HD systems due to a critical safety issue impacting their CSRs mode. This issue brings into question the stated precision of these systems during stereotactic radiosurgery (SRS) treatments. The malfunction could lead to the misalignment of patients at the isocenter, ultimately causing erroneous dose delivery—a potentially serious risk for cancer patients relying on accurate radiation therapy.
Read on for the essential details surrounding this recall, including what it means for users and steps to take in light of this announcement.
## Why This Recall Is Important
When undergoing stereotactic radiosurgery, achieving accurate patient positioning is critical to ensure the correct delivery of radiation. The Catalyst HD and Catalyst+ HD systems are relied upon for their high precision capabilities during these highly targeted treatments. Unfortunately, C-RAD has identified that this precision cannot be guaranteed for all couch angles and system setups in CSRs mode.
### Key Risks of This Recall:
- **Misalignment at Isocenter**: The system may falsely indicate that a patient is correctly positioned at the isocenter, even if the isocenter is outside the acceptable tolerance range.
- **Erroneous Dose Delivery**: Mispositioning during treatment could result in delivering radiation to unintended areas, potentially harming healthy tissue or reducing the treatment's effectiveness.
This recall highlights a significant concern for healthcare providers and patients relying on this equipment for safe and effective treatment.
