Detection Technology has launched an extra-large flat panel detector aimed at medical cone-beam computed tomography (CBCT) and image-guided radiation therapy (IGRT), as vendors continue to look for larger imaging fields of view and faster acquisition in clinical workflows.
In a press release dated 11 November 2026, the company said its X-Panel 4386a FPM uses a 430 × 860 mm active area, which it said is about twice the imaging area of a conventional 43 × 43 cm detector. The detector is designed to support broader anatomical coverage in a single acquisition and to reduce the need for multiple scans in some configurations.
Detection Technology said that, depending on system geometry, the larger detector area can expand the reconstructed field of view from about 25 cm with a typical 43 × 43 cm detector to up to 50 cm. The company said capturing more of a patient’s cross-section in each projection can help reduce truncation artifacts.
“Customers have been asking for more detector coverage while maintaining the speed required for dynamic imaging. In X-Panel 4386a FPM, we combine an extra-large single-glass TFT sensor with a CsI scintillator and fast readout electronics. This gives OEMs more freedom to design new CBCT systems, cover larger anatomies and explore new imaging workflows and applications,” said Tuomas Holma, Product Director at Detection Technology.
The company said the detector supports high-speed acquisition using fast readout electronics and dual-sided readout, and includes binning and region-of-interest modes intended to let system designers trade off spatial resolution and imaging speed depending on the protocol. It also said shorter acquisitions can reduce motion-related image degradation and improve patient comfort.
According to Detection Technology, the detector is based on a continuous single-glass amorphous silicon TFT sensor with a direct-deposition cesium iodide (CsI) scintillator. The company said the single-glass architecture avoids seams or gaps across the imaging area and supports more uniform calibration, and that built-in mounting for an anti-scatter grid is intended to support scatter reduction in large-field-of-view CBCT.
Two product variants were announced: the X-Panel 4386a FPM-CSV-TG, described as optimised for medical CBCT, and the X-Panel 4386a FPM-CSV-TG-S, which adds internal shielding intended to protect electronics from MV scatter in radiotherapy environments for kV CBCT in IGRT workflows. Both variants feature 140 µm pixel pitch, a 3072 × 6144 pixel matrix, and a 10G Ethernet interface, with Windows and Linux SDK support, the company said.
Detection Technology said it will showcase the X-Panel 4386a FPM at RSNA 2026 in Chicago from 29 November to 2 December 2026.
