This paper presents a comparison study between 10 automatic and six interactive methods for liver segmentation from contrast-enhanced CT images. It is based on results from the "MICCAI 2007 Grand Challenge" workshop, where 16 teams evaluated their algorithms on a common database. A collection of 20 clinical images with reference segmentations was provided(More)
Eight patients aged 1 month up to nine years with congenital diaphragmatic hernias (seven left sided postero-lateral, one right-sided antero-medial), who presented outside of the neonatal period, are reported, four are described in detail. Radiographic presentation was obvious in four patients, simulated inflammatory lung disease in one and pneumothorax in(More)
Skeleton is a frequently applied shape feature to represent the general form of an object. Thinning is an iterative object reduction technique for producing a reasonable approximation to the skeleton in a topology preserving way. This paper describes a sequential 3D thinning algorithm for extracting medial lines of objects in (26, 6) pictures. Our algorithm(More)
At the Department of Pediatric Surgery in Graz, 31 boys and 23 girls were operated on for congenital diaphragmatic hernia (CDH) from 1978 to 1994. In 49 patients the defect was on the left, in five on the right side. In 46 cases, the hernia was diagnosed within the first week of life; in eight children at a later date. 19 children (35%) died. 25 of the 35(More)
The segmentation of tubular tree structures like vessel systems in volumetric datasets is of vital interest for many medical applications. We present a novel approach that allows to simultaneously separate and segment multiple interwoven tubular tree structures. The algorithm consists of two main processing steps. First, the tree structures are identified(More)
Biodegradable Mg alloys are of great interest for osteosynthetic applications because they do not require surgical removal after they have served their purpose. In this study, fast-degrading ZX50 Mg-based implants were surface-treated by micro-arc oxidation (MAO), to alter the initial degradation, and implanted along with untreated ZX50 controls in the(More)
In this paper we propose a technique for 3-D segmentation of abdominal aortic aneurysm (AAA) from computed tomography (CT) angiography images. Output data form the proposed method can be used for measurement of aortic shape and dimensions. Knowledge of aortic shape and size is very important for selection of appropriate stent graft device for treatment of(More)
Liver segmentation is an important prerequisite for planning of surgical interventions like liver tumor resections. For clinical applicability, the segmentation approach must be able to cope with the high variation in shape and gray-value appearance of the liver. In this paper we present a novel segmentation scheme based on a true 3D segmentation refinement(More)
OBJECTIVE To describe the potential and application of interventional image guided procedures in the paediatric urinary tract. PATIENTS AND METHODS The different techniques are illustrated using case reports. The examples comprise established indications such as percutaneous nephrostomy for compromised kidneys in obstructive uropathy and infection,(More)
Today CT represents about 10% of all ionizing radiation based imaging modalities, but delivers more than 50% of the total collective dose for diagnostic imaging. Compared to adults the radiation sensitivity of children is considerable higher than in adults. Additionally children differ from adults--factors like body size, mass, density, proportions as well(More)
