KOL-Index: 20 PURPOSE: Treatment planning for radiosurgery depends on the precise definition of radiation target volumes. For vascular pathologies such as arteriovenous malformations (AVM), the most usual technique remains standard X-ray projection imaging, most often carried out under stereotactic conditions. To further benefit from the advantages of two-dimensional digital subtraction angiography (DSA), ...

KOL-Index: 17 Abstract. The aim of this study was optimization of the radiation dose–image quality relationship for a digital scanning method of scoliosis radiography. The examination is performed as a digital multi-image translation scan that is reconstructed to a single image in a workstation. Entrance dose was recorded with thermoluminescent dosimeters placed dorsally on an Alderson phantom. At the ...

KOL-Index: 11 Abstract. Although analysis of scoliotic deformity is still studied extensively by means of conventional roentgenograms, computer-assisted digital analysis may allow a faster, more accurate and more complete evaluation of the scoliotic spine. In this study, a new computer-assisted measurement method was evaluated. This method uses digital reconstruction images for quantitative analysis of ...

KOL-Index: 7 Overview images of long parts of the human anatomy (spine, colon, legs) can be generated from a translated series of digital image intensifier (II) X-ray images using dedicated match-and-paste algorithms. The purpose of this study is to clarify the relation between the X-ray dose of the overlapping image series and the resulting image quality (contrast and noise) and image geometry of the ...

KOL-Index: 7 Blood pool agent (BPA) contrast-enhanced magnetic resonance angiography (CE-MRA) images have been acquired during the first-pass of the contrast agent and in the steady-state. Arterial visualization, which is hampered in the steady-state owing to simultaneous enhancement of arteries and veins, can be improved if the central arterial axis (CAA) is known. A method is presented that utilizes ...

KOL-Index: 7 A method is introduced to automatically find the coronary axis based on two or more user-defined points, even in the presence of a severe stenosis. The coronary axis is determined by finding a minimum cost path (MCP) in a feature image in which the tubular-like structures are enhanced. The results of the proposed method were compared with manually drawn central axes to estimate the accuracy. ...

KOL-Index: 7 Blood pool agents (BPAs) for contrast-enhanced magnetic resonance angiography (CE-MRA) allow prolonged imaging during the steady state when the agent is distributed through the complete vascular system. This increases both the spatial resolution and the contrast resolution. However, simultaneous venous and arterial enhancement hampers interpretation. For the pelvic region of the vasculature, ...

KOL-Index: 6 Nowadays, conventional X-ray radiographs are still the images of choice for evaluating spinal deformaties such as scoliosis. However, digital translation reconstruction gives easy access to high quality, digital overview images of the entire spine. This work aims at improving the description of the scoliotic deformity by developing semi-automated tools to assist the extraction of anatomical ...
