    • A fiducial marker system (210a-c) comprises a first unit and a second unit. The first unit is patient affixable and comprises a partly spherical inner surface having a first center point that is adapted to receive a touch probe measurement head for measuring the spatial position of the center point. The second unit is releasably attachable to an outer surface of the first unit, and has a second center point, wherein the first center point and the second center point are substantially identical when the second unit is attached to the first unit. For stereotactic therapy, a patient is imaged with the first and second unit assembled. Then the second unit is detached. A stereotactic frame (300) is attached to the first units via arms. Thus frameless imaging is provided in a frame based stereotactic surgery system with high precision. Repeated assembly of the frame (300) to the first units, remaining in the patient, provides advantageous fractionized stereotactic radiotherapy.
    • 基准标记系统(210a-c)包括第一单元和第二单元。 第一单元是可耐用的,并且包括部分球形的内表面,其具有适于接收用于测量中心点的空间位置的测头测量头的第一中心点。 第二单元可释放地附接到第一单元的外表面,并且具有第二中心点,其中当第二单元附接到第一单元时,第一中心点和第二中心点基本相同。 对于立体定向治疗,患者以第一和第二单元组装成像。 然后第二个单元是分离的。 立体定向框架(300)通过臂附接到第一单元。 因此,在基于帧的立体定向手术系统中提供无框架成像,其精度高。 保留在患者体内的框架(300)重复组装到第一单元提供有利的分级立体定向放射治疗。

    • The present invention relates to a protective board forming part of a packing for cylindrical rolls (1) of wound webs of material, especially paper webs, the packing comprising a sheet- or web-shaped wrapping (3) to be arranged on the circumferential surface of the roll, and the protective board (4, 4') which is adapted to be arranged on one of the two opposite end surfaces of the roll. To be able to absorb blows and impacts and to reduce the risk of deforming the web of material, for example when placing the roll end surface on a rough or uneven surface, the protective board has a thickness in the range of 5-12 mm and is made of a porous or medium hard fibreboard which has a density in the range of 100-750 kg/m and is composed of long fibres, e.g. from waste paper or papermaking pulp, and short fibres preferably deriving from sawdust, the portion of short fibres amounting to 70-90 % of the total dry solids content of the fibreboard.
    • 保护板技术领域本发明涉及一种保护板,其形成用于圆筒形卷筒(1)的卷材的一部分的卷材,特别是纸幅,该包装件包括布置在圆周表面上的片状或网状包装(3) 以及适于布置在辊的两个相对端表面中的一个上的保护板(4,4')。 为了能够吸收冲击和冲击并降低材料网变形的风险,例如当将辊端面放置在粗糙或不平坦的表面上时,保护板的厚度在5-12mm的范围内,并且 由多孔或中等硬纤维板制成,其密度在100-750kg / m 3的范围内,并且由长纤维组成,例如 来自废纸或造纸纸浆以及优选衍生自锯屑的短纤维,短纤维的部分占纤维板总干燥固体含量的70-90%。
