Okay. So let me just comment in general about Photon counting and what it's capable of. And Suraj you ask your question about how they'll manifest themselves in the field. Luckily, a lot will depend a lot on how our customers choose to implement it. So photon counting has technology. It's main benefit, there's two huge benefits from Photon counting. Number one, since it counts, X ray photons versus measuring, something that's a proxy for, let's say, amount of equivalent to what would be a waveform as an amplitude, instead of measuring the value of that we're just counting. This is like AM to FM, AM used to measure the amplitude, it was susceptible to noise. So photon counting detector, because it does not measure anything that's an intensity, it is not subject to noise. So there's no -- so if you take a signal to noise ratio, which is the number one thing that impacts your quality of your image, if the noise which is in the denominator is zero, so in -- so you get theoretically very, very high signal to noise ratio. So, conversion efficiency of a photon counting detector is very, very high. And what that means is, you get very good image quality with very low -- that means these detectors are exceptionally sensitive. That's number one. Exceptionally sensitive detectors that and every photon of X-ray is used in the imaging process versus their traditional detectors, a lot of that is lost and it cause noise etcetera. So those reduction sensitivity, number one. Number two, and this is where some of the applications creativity will come in with from our customer side, which is photon counting detectors are able to -- while we're capturing and counting the photons, we put them in different buckets of energy levels. So that means you get – you can just differentiate very, very precisely, all kinds of very precise material discrimination. Now what that means is, you get, you know, you've heard people want dual energy, they want spectral imaging, but it all comes down to is, can you -- how well can you image soft tissue. So photon counting detectors, because their inherent ability to do energy discrimination, and the way we build our photon counting detector and it's the software algorithms, we can do very, very precise energy discrimination, which then – like you take these as the foundational capabilities, what we expect is that our customers will apply these to their new development and come up with new applications, new clinical algorithms and it's really love to watch and see how they position them and in terms of their effectiveness. So I can't quite answer that part of the question yet. But we know that the capabilities bring enormous potential opportunities to the table for new applications.
