Zap-X Radiosurgery System 300150Recalls & reported problems
Zap Surgical Systems, Inc. · The self-shielded ZAP-X® Radiosurgery System is a computer-controlled system for planning and delivering non-invasive stereotactic radiosurgery for tumors, lesions and conditions in the brain, head, and neck when radiation treatment is indicated. The system is self-shielded for ionizing radiation, allowing it to be installed in a non-bunker environment. A linear accelerator mounted on a dual-gantry provides a therapeutic radiation source, and a kV imaging system is used to locate and track the treatment target throughout the treatment. · Class 2

Recalls naming this device
- Jul 25, 2025Class IIOpen, Classified
If the radiosurgery system triggers a proximity error message during a long gantry move (greater-than180 degrees), and a subsequent proximity error message occurs after the automatic reduction of speed, a software defect could potentially lead the collimator to collide with patient shoulders or the patient table.

- Jul 5, 2022Class IIOpen, Classified
Software issue identified in cases of initial patient setup with large (greater-than-or-equal-to 1.5 degrees) rotational deviations, between digitally reconstructed radiographs, and pre-delivery X-ray images. In these cases the transitional alignment algorithm may incorrectly calculate the new treatment table offset values, leading to an incorrect position for the subsequent treatment isocenter.
