The "Laboratory for Advanced Computed Tomography Imaging" is dedicated to developing next generation x-ray and computed tomography solutions to make additional diagnostic and therapy information available that exceeds current clinical standards. When it comes to diagnostics and therapy monitoring, the current tendency is to look at simple ‘gray-values’ (representing attenuation) and contrast differences to determine whether anatomical or pathological changes have occurred. In order to extend current possibilities and limitations, several new approaches are under investigation in our Lab, namely spectral / photon-counting and phase-contrast / dark-field imaging. Both of these technologies promise to significantly extend current diagnostic possibilities; however, clinical standards, for example with respect to radiation exposure and acquisition speed, need to be maintained for future clinical systems.  To fulfill current clinical standardsnow and in the future, we are investigating new acquisition schemes (e.g. sparse sampling) in combination with advanced reconstruction algorithms. This type of approach is a central ingredient to our research: the harmonization between hardware and software, reconstruction as well as post processing, to achieve integrated clinical solutions. Our strong collaboration with experts in clinical departments and the medical device industry guides and accelerates the translation of new technologies into early clinical application.The "Laboratory for Advanced Computed Tomography Imaging" is located in the Institute for Diagnostic and Interventional Radiology at Klinikum rechts der Isar der Technischen Universität München. The lab is connected with the Chair of Biomedical Physics at TUM.
