RSNA 2019 Future News: XC-Pyxis – a four-side buttable ASIC

- By Jacqueline Wheeler

At RSNA 2019, Direct Conversion’s top team will be sharing advance details of a new product, the XC-Pyxis, a four-side buttable ASIC that is being designed specifically to support radiologists and clinicians as they strive to deliver the best outcomes for their patients.

The XC-Pyxis is a single-element, hybrid detector technology that our team of world-class specialists, led by CTO Christer Ullberg (pictured above, third from right, at booth 2973) are creating in response to the ongoing conversations we are having with medical experts across the globe. The advantage of the XC-Pyxis is that it can be assembled into larger detectors without gaps between the elements. This near seamless construction has a direct impact on the image quality obtained as it reduces potential artefacts and eases the capture of images, as well as making it possible to engineer detectors of different sizes and shapes.

To create the XC-Pyxis, Ullberg and his team have exploited an enabling technology known as Through Silicon Vias (TSV) in which signals are routed through the back of the chip. This avoids having wires at the sides so the chip can be tiled more closely to its neighbours.

As well as enhanced image quality and the potential for an increase in the size of the tiled detectors, the XC-Pyxis is being designed with a number of other important features that we look forward to demonstrating to our customers. Currently, these include the acquisition of data in up to six energy bins per pixel and on-chip binning which widens the possible uses of the detector by improving separation of contrast media in an image and improved separation of body tissue.

Our leadership team will be on hand at our booth to explain how our rapidly evolving technology can help you, including Christer, Ullberg, CEO Spencer Gunn, and our specialist Technical Sales Manager for Medical, York Haemisch.
