TL;DR: The goal in the study was to determine the accuracy of the simulations generated by 3D imaging technology, and the results were 90% accuracy in volume and a mean of 4-mm (98% accuracy) surface contour.

TL;DR: A novel 3-D imaging technique based on the synthetic aperture technology in which the imaging resolution is significantly improved and does not degrade with the increase of the range.
Abstract: Traditional three-dimensional (3-D) laser imaging systems are based on real aperture imaging technology, whose resolution decreases as the range increases. In this paper, we develop a novel 3-D imaging technique based on the synthetic aperture technology in which the imaging resolution is significantly improved and does not degrade with the increase of the range. We consider an imaging laser radar (ladar) system using the floodlight transmitting mode and multi-beam receiving mode. High 3-D imaging resolutions are achieved by matched filtering the linear frequency modulated (LFM) signals respectively in range, synthetic aperture along-track, and the real aperture across-track. In this paper, a novel 3-D imaging signal model is given first. Because of the motion during the transmission of a sweep, the Doppler shift induced by the continuous motion is taken into account. And then, a proper algorithm for the 3-D imaging geometry is given. Finally, simulation results validate the effectiveness of the proposed technique.

TL;DR: This issue features original research ranging from design of stimuli for human perception, optics applications, and image enhancement to novel imaging modalities in both color and infrared spectral imaging, gigapixel imaging as well as a systems perspective to imaging.
Abstract: Imaging systems have numerous applications in industrial, military, consumer, and medical settings. Assembling a complete imaging system requires the integration of optics, sensing, image processing, and display rendering. This issue features original research ranging from design of stimuli for human perception, optics applications, and image enhancement to novel imaging modalities in both color and infrared spectral imaging, gigapixel imaging as well as a systems perspective to imaging.

TL;DR: One of the main driving forces for the current development in CT is for applications in cardiology, and with multislice detectors, spiral acquisition, and subsecond rotation times, CT continues to develop and to play a major role in clinical imaging, in particular for the assessment of cardiovascular disease.
Abstract: The recent development of combined positron emission tomography/computed tomography (PET/CT) instrumentation is an important evolution in imaging technology. Since the introduction of the first prototype CT scanner in the early 1970s, tomographic imaging has made significant contributions to the diagnosis and staging of disease. Rapid commercial development followed the introduction of the first CT scanner in 1972, and within 3 years of its appearance more than 12 companies were marketing, or intending to market, CT scanners; about half that number actually market CT scanners today. With the introduction of magnetic resonance imaging (MRI) in the early 1980s, CT was, at that time, predicted to last another 5 years at most before being replaced by MRI for anatomical imaging. Obviously, this did not happen, and today, with multislice detectors, spiral acquisition, and subsecond rotation times, CT continues to develop and to play a major role in clinical imaging, in particular for the assessment of cardiovascular disease. Indeed, one of the main driving forces for the current development in CT is for applications in cardiology.
