    • A disc prosthesis, suitable for replacing an intervertebral disc, includes a first (1; 1') and a second (2; 2') articulation component. The components comprise respective endplates (11, 21; 11', 21') suitable for being anchored to respective vertebrae. . The first articulation component further comprises a spacer member (13; 13') suitable for being interposed between the endplates, and which is disposed on the endplate (11; 11') of the first component (1; 1') and has a convex articulation surface (19; 19') suitable for being placed in contact with a corresponding concave articulation surface (29; 29') disposed on the endplate of- the second component. The articulation -components are made at least partially of polyethylene reinforced with calcium phosphate, one of same further having a part (17; 27'), facing towards the other articulation component, which is made of ultra-high molecular weight polyethylene, and on which one of the articulation surfaces is provided.

    • The method allows prefiltering, segmentation and analysing time sequence of volumetric images in the field of medical diagnosis. In particular the system allows detecting and selecting, from anatomical images, for example cardiac images, an organ or part of it by means instruments of segmentation and carrying out quantitative analysis for anatomical studies, function and perfusion. From the images cardiache is calcola the volume of the cavity and the thickness of the miocardium and as these variano in the tempo; in the images cardiache of perfusion, is calculated automatically the ventricular wall by means of suitable operations of segmentation and, then, is subdivide this wall in a plurality of selected regions obtaining, by means of a graphic window, time/intensity curves relative to each zone, comprised the reference curve corresponding to the ventricular cavity. The method allows di: 1) to filter the curve tempo/intensita' from heat noise and due to the hardware of the machine and by artefacts due to meccanismi fisiologici, such as the heart beat and attivita' vaso-motoria spontanea; 2) estract data relative to the flow in the regions of the myocardium wall selected automatically.
    • 该方法允许在医学诊断领域对体积图像进行预过滤,分割和分析。 特别地,该系统允许从解剖图像检测和选择例如心脏图像,器官或其一部分通过分割仪器进行解剖学研究,功能和灌注的定量分析。 从图像心跳是calcola的体积的腔和miocardium的厚度和这些variano在节奏中; 在图像灌注心电图中,通过适当的分割操作自动计算心室壁,然后将该壁细分为多个选定区域,通过图形窗口获得相对于每个区域的时间/强度曲线 包括对应于心室的参考曲线。 该方法允许di:1)过滤来自热噪声的曲线速度/强度,并且由于机器的硬件以及由于心跳反应而产生的人为因素,例如心脏跳动和自发性血管运动自发; 2)相对于自动选择的心肌壁区域的流量估计数据。
