IVUS and OCT: Either or Survivor …

Abstract: Since its introduction over 20 years ago, intravascular ultrasound (IVUS) has become the dominant imaging technology, helping us to better understand vessel biology and guiding interventional procedures, and providing information on atherosclerosis progression or regression in clinical trials.

Medical imaging examination review and quality assurance system and method

Abstract: The present invention is a computer-based review and quality assurance system and method for physicians who use portable imaging technology to diagnose and treat patients at a point of care. The system and method facilitates the credentialing of physicians, provides on-going quality assurance (QA), and integrates medical imaging equipment with software that runs over a network. Such credentialing assists medical institutions by identifying physicians who effectively use and diagnose patients with the imaging equipment.

The value of imaging technology to patients' health

Abstract: The ultimate goal of imaging research, indeed, all medical research, is the improvement of human health. However, the technologic nature of our discipline often results in research that assesses a technology or the application of a technology in terms of the information it provides rather than its relationship to care of patients. Dr. Rosenquist’s paper [i ] describes an example of how assessing a technology solely on the basis of the information it provides can be misleading with regard to the effects of that technology on patients’ health. In a broad sense, nearly all of our literature deals with imaging technology assessment. An unfortunate proportion of imaging publications are retrospective, without suitable controls or verification of diagnoses, and they employ dubious or irreproducible measures of efficacy. In evaluating the other publications, we can consider a five-stage hierarchy of imaging technology assessment: imaging efficacy, diagnostic efficacy, therapeutic efficacy, evaluation of the patients’ outcomes, and cost-effectiveness assessment. Imaging efficacy is the level of assessment most commonly encountered in prospective imaging research. Evaluation of imaging efficacy is typified by the work of Abu-Yousef et al. [2], who sought to determine the potential of sonography in identifying patients with appendicitis. This level of assessment is an important and necessary first step in assessing the value of an imaging technology. However, as Dr. Rosenquist has shown, little relationship may exist between imaging efficacy and providing benefits to patients. Indeed, only a few imaging studies have sought to develop a link between advances in imaging technology and benefits to patients. This lack of data has provided a rationale for often misguided technology regulation and reimbursement conmisguided technology regulation and reimbursement constraints. Moreover, the absence of reliable information puts radiologists at a disadvantage in selecting and using technology, especially in an environment that increasingly puts us and our associates at financial risk for applying technologies that do not result in cost-effective care. Levels two through five of the assessment hierarchy potentially could contribute to an information base that would correct these deficiencies. Level two is diagnostic efficacy. Studies dealing with diagnostic efficacy seek to determine the importance of the use of a technology in establishing or ruling out a diagnosis. An example of a measure of diagnostic efficacy that has been used successfully in assessing applications of imaging technology is the log likelihood ratio [3]:

Airport Body Scanners: The Role of Advanced Imaging Technology in Airline Passenger Screening

Abstract: This report looks at privacy and health issues, as well as effectiveness, of advanced imaging technology (AIT) scanners at airports deployed by the Transportation Security Administration (TSA).

Advanced imaging research and development at DARPA

Abstract: Advances in imaging technology have huge impact on our daily lives. Innovations in optics, focal plane arrays (FPA), microelectronics and computation have revolutionized camera design. As a result, new approaches to camera design and low cost manufacturing is now possible. These advances are clearly evident in visible wavelength band due to pixel scaling, improvements in silicon material and CMOS technology. CMOS cameras are available in cell phones and many other consumer products. Advances in infrared imaging technology have been slow due to market volume and many technological barriers in detector materials, optics and fundamental limits imposed by the scaling laws of optics. There is of course much room for improvements in both, visible and infrared imaging technology. This paper highlights various technology development projects at DARPA to advance the imaging technology for both, visible and infrared. Challenges and potentials solutions are highlighted in areas related to wide field-of-view camera design, small pitch pixel, broadband and multiband detectors and focal plane arrays.
