A Deep learning Approach to Generate Contrast-Enhanced Computerised Tomography Angiography without the Use of Intravenous Contrast Agents
Anirudh Chandrashekar, Ashok Handa, Natesh Shivakumar +3
Contrast-enhanced computed tomography angiograms (CTAs) are widely used in cardiovascular imaging to obtain a non-invasive view of arterial structures. However, contrast agents are…
A Deep Learning Approach to Automate High-Resolution Blood Vessel Reconstruction on Computerized Tomography Images With or Without the Use of Contrast Agent
Anirudh Chandrashekar, Ashok Handa, Natesh Shivakumar +3
Existing methods to reconstruct vascular structures from a computed tomography (CT) angiogram rely on injection of intravenous contrast to enhance the radio-density within the vess…
Planck pre-launch status: calibration of the Low Frequency Instrument flight model radiometers
F. Villa, L. Terenzi, M. Sandri +71
The Low Frequency Instrument (LFI) on-board the ESA Planck satellite carries eleven radiometer subsystems, called Radiometer Chain Assemblies (RCAs), each composed of a pair of pse…
The linearity response of the Planck-LFI flight model receivers
A. Mennella, F. Villa, L. Terenzi +37
In this paper we discuss the linearity response of the Planck-LFI receivers, with particular reference to signal compression measured on the 30 and 44 GHz channels. In the article…
Planck pre-launch status: Low Frequency Instrument calibration and expected scientific performance
A. Mennella, M. Bersanelli, R. C. Butler +83
We give the calibration and scientific performance parameters of the Planck Low Frequency Instrument (LFI) measured during the ground cryogenic test campaign. These parameters char…
Planck pre-launch status: Design and description of the Low Frequency Instrument
M. Bersanelli, N. Mandolesi, R. C. Butler +109
In this paper we present the Low Frequency Instrument (LFI), designed and developed as part of the Planck space mission, the ESA program dedicated to precision imaging of the cosmi…
