title = "Initial investigations of scatter cross-talk in simultaneous biplane high-speed 1000 frames per second neuro-angiography using Monte Carlo simulations",
abstract = "New photon-counting detectors (PCD) from Direct Conversion facilitate up to 1000 frames per second and 1 ms frame-acquisition times. When using these detectors for biplane contrast-media tracking in neuro-angiographic procedures, simultaneous acquisitions are utilized and cross-scatter between planes could degrade image quality. To quantify cross-scatter contributions, we model simultaneous biplane high-speed neuro-angiography in EGSnrc using the Zubal head phantom. Results indicate an increase in scatter due to cross-talk ranging from 4\%-56\% for AP projections and 48\%-71\% for lateral projections depending on detector orientation. This increase in scatter can be mitigated using anti-scatter grids, energy thresholding and increased air gaps.",
