CTI presents photon-counting breast CT at RSNA 2015 with great success

2015/12/23, CT Imaging GmbH
RSNA2015 Photon-counting Breast CT
Diagnostic procedures for early and reliable diagnosis of breast cancer are still insufficient today in one or several regards.
CT of the breast shall overcome this situation and, in particular, increase sensitivity and specificity by offering the following features in combinaton:
  • Superposition-free imaging with very high spatial resolution of 100 μm or better in all three spatial dimensions
  • Dose levels low enough to conform with mammographic screening regulations
  • Dynamic imaging with contrast medium application when indicated

CT pioneers spell out how to reduce patients' anxiety over dose

2015/02/08, AuntMinnieEurope

Few people have had greater individual impact on the evolution of CT scanners than Dr. Willi Kalender, PhD, the pioneer of spiral systems. As the director of the Institute of Medical Physics at the Friedrich-Alexander University of Erlangen-Nürnberg in Germany, he is currently overseeing projects relating to CT imaging of the heart, micro-CT, and image-based navigated interventions.

CTDI and Patient Dose: A European Perspective

2013/07/29 - 2013/08/02, The American Association of Physicists in Medicine Annual Meeting, Charlotte, NC (USA)

Dose in CT has been a dominant topic in Medical Physics for at least a decade. This was for good reason since increasing use of CT necessarily led to an increase of cumulative dose to the population and inappropriate use of CT in some cases led to an unnecessarily high exposure of patients with subsequent coverage in the U.S. media.

Effect of shaped filter design on dose and image quality in breast CT

2013/06/21, Phys Med Biol. 58 (13): 4205-23

The purpose of this study was to investigate the effect of shaped filters specifically designed for dedicated breast computed tomography (CT) scanners on dose and image quality. Optimization of filter shape and material in fan direction was performed using two different design methods, one aiming at homogeneous noise distributions in the CT images and the other aiming at a uniform dose distribution in the breast.

High-resolution spiral CT of the breast at very low dose: concept and feasibility considerations

2012, Eur Radiol (2012) 22: 1-8

Objective Mammography, today’s standard imaging approach, has deficits with respect to the superimposition of anatomical structures. Dedicated CT of the breast so far indicated that it can provide superior soft-tissue imaging, but that it still has significant limitations with respect to spatial resolution and dose. We have assessed novel dedicated breast CT technology.

German pioneers bury their differences for breast imaging's sake

December 6, 2012 -- Arguably one of the most eye-catching and unexpected moments at last week's RSNA meeting was the sight of Willi Kalender, PhD, and Dr. Christiane Kuhl enjoying a long, amicable chat in the Lakeside Center. These two well-known scientists have championed CT and MRI respectively for many years, fighting their corner with intense passion and evangelical-like zeal, but now they're forgetting their differences and working together on potentially ground-breaking research.

Iterative reconstruction methods in X-ray CT

2012/04/02, Physica Medica 28: 94–108

Iterative reconstruction (IR) methods have recently re-emerged in transmission x-ray computed tomography (CT). They were successfully used in the early years of CT, but given up when the amount of measured data increased because of the higher computational demands of IR compared to analytical methods.

German group reports progress on dedicated breast CT

2011/06/27, AuntMinnieEurope

June 27, 2011 -- Dedicated breast CT has long been proffered as a potential rival to mammography for brest screening, but early prototype systems have been limited by higher radiation dose and lower resolution. In a new paper in European Radiology, however, German researchers report progress in addressing both concerns.

Verein Medical Valley verdammt sich selbst zum Erfolg

Als am 26. Januar 2010 der Verein Medical Valley Erlangen/Metropolregion Nürnberg (EMN) vom Bundesministerium für Bildung und Forschung zu einem wissenschaftlichen "Batzen", gekürt wurde und staatliche Fördermittel in Höhe von 40 Millionen für strategische Produkte angekündigt wurden, war das der eigentliche Startschuss für den drei Jahre zuvor gegründeten Verein. Nun wurde Zwischenbilanz gezogen. [...] Konkrete Produkte- und solche mit "strategischer Bedeutung" zu entwickeln ist schließlich das Ziel der Förderung - gibt es natürlich auch, und mit Prof. Willi Kalender ist auch einer der führenden Köpfe Deutschlands bei der Entwicklung innovativer bildgebender Verfahren Zeuge für erste Erfolge.
