Tomographic reconstruction from cone-beam X-ray data is only solved for static objects, e. g. the abdomen. In cardiac imaging, a rotational angiography sequence takes approx. 5 s and therefore spans several heart beats. Since such an acquisition scheme forces a trade-off between consistency of the scene and reasonable angular spacings between camera positions, standard reconstruction techniques...

MEDISIP Medical Imaging and Signal Processing Group, Ghent University, IBBT-IBiTech, iMinds Medical IT, Ghent, Belgium In Time-of-Flight PET/MRI systems accurate attenuation correction, based on the MRI image, is not straight forward. An alternative is attenuation correction based on emission data only. This is for instance done by simultaneous reconstruction of attenuation and activity with th...

BACKGROUND Patients having unilateral breast reconstruction often require a second stage procedure on the contralateral breast to improve symmetry. In order to provide immediate symmetry and minimize the frequency and extent of secondary procedures, we began performing simultaneous contralateral balancing operations at the time of initial reconstruction. This study examines the indications, saf...

This paper focuses on minimizing the time requirement for CT capture through innovative simultaneous x-ray capture method. The state-of-the-art CT imaging methodology captures a sequence of projections during which the internal organ movements may lead to poor reconstruction due to motion artefacts. Traditional CT scanners' minimize such effect by taking more projections than necessary. In this...

BACKGROUND Multiligamentous injuries of knee are a complex problem in orthopaedics. Combined ACL-PCL injuries are uncommon, usually associated with knee dislocations. Extremity vascular status is essential because of possible arterio-venous compromise. These complex injuries require a systematic evaluation and treatment. Single setting simultaneous arthroscopic ACL and PCL reconstruction or a s...

We introduce a new algorithm for the reconstruction of functional brain activations from near-infrared spectroscopic imaging (NIRSI) data. While NIRSI offers remarkable biochemical specificity, the attainable spatial resolution with this technique is rather limited, mainly due to the highly scattering nature of brain tissue and the low number of measurement channels. Our approach exploits the s...

An integrated system for performing interventional magnetic resonance angiography (MRA) with actively visualized instruments and real-time image fusion was implemented on a 1.5 T scanner. True fast imaging with steady precession (TrueFISP) imaging provided high acquisition speed paired with high signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) for the simultaneous visualization of ...

The author is presenting his experience in surgical reconstruction of the dysplastic acetabular roof. combined with a simultaneous reduction subluxed hip. This method was under author’s elaboration since 1927 and it named by him as transiliac osteotomy 1958. Detailed technique described.

Purpose: To achieve high-resolution diffusion-weighted imaging (DWI) with short duration acquisition and robustness to patient motion. In [1, 2], high resolution (HR) dense k-space sampling of a DW image was achieved with a series of anisotropically oversampled acquisitions (so-called "shots"), which amounts to sampling k-space in a non-Cartesian manner, and by reconstruction in the image space...
