图2A的腹腔镜探针头102还包括用于促进对来自受试者体腔内放射性药物的辐射源定位的装置。
The laparoscopic probe head 102 of FIG. 2A also comprises a means for facilitating the localization of a source of radiation from a radiopharmaceutical within a cavity of a subject.
在图2A的实施例中，腹腔镜探针200包括用于使伽马探测器相对于辐射屏蔽114移动以调整伽马探测器通过探测孔(即，通过由辐射屏蔽114在腹腔镜探针200的探测端处形成的空隙)的视场的机构。
In the embodiment of FIG. 2A, the laparoscopic probe 200 comprises a mechanism for moving the gamma detector relative to the radiation shielding 114 to adjust the field of view of the gamma detector through the detection aperture, that is, through the void formed by the radiation shielding 114 at the detection end of the laparoscopic probe 200.
特别地，图2A的闪烁体110(和光电探测器112)可以在探针头102内移动，以调整伽马辐射探测器的视场。
In particular, the scintillator 110 (and photodetector 112) of FIG. 2 A is moveable within the probe head 102 to adjust the field of view of the gamma radiation detector.
闪烁体110的位置决定了传感器的视场，如图2B所示。
The position of the scintillator 110 determines the field of view of the sensor as shown in FIG. 2B.
使用这种机构代替准直器的优点是灵敏度不受由于准直器的填充因素引起的附加损失的影响。
The advantage of using such a mechanism in place of a collimator is that the sensitivity is not affected by additional losses due to the fill factor of the collimator.
在使用中，用第二准直器代替第一准直器来调整设备的视场是不切实际的，相应地，可调整伽马辐射探测器提供了许多优点。
In use, it is impractical to replace a first collimator with a second collimator in order to adjust a field of view of the device—accordingly, an adjustable gamma radiation detector provides many advantages.
腹腔镜探针200的灵敏度和可调整性对于腹腔镜应用是特别受关注的：腹腔镜探针200的外径受到限制，并且因此伽马辐射探测器本身的尺寸也非常小，并且因此不希望在灵敏度和可调性之间进行权衡(trade-off)。
The sensitivity and adjustability of the laparoscopic probe 200 are particular concerns for the laparoscopic application: the outer diameter of the laparoscopic probe 200 is restricted and therefore the size of the gamma radiation detector itself is also very small, and so it is undesirable to trade-off between sensitivity and adjustability.
图2B显示了极坐标图，其显示了探针的角视场，该探针具有6mm直径的伽马探测元件、3mm厚的组合壳体106和侧面屏蔽114、以及3mm的后部屏蔽116。
FIG. 2B shows polar plots showing the angular field of view for a probe with a 6 mm diameter gamma detection element, 3 mm thick combined casing 106 and side shielding 114, and 3 mm rear shielding 116.
闪烁体110前部的位置距离探测孔(侧面屏蔽114的边缘)从左到右分别是0mm、3mm和6mm。
The position of the front of the scintillator 110 from the detection aperture (edge of the side shielding 114) is, from left to right, 0 mm, 3 mm, and 6 mm respectively.
本领域技术人员将理解，尽管在图2中，闪烁体110在侧面屏蔽内部移动，但是在替代实施例中，可以是侧面屏蔽114被布置成在探针头内移动，使得探测器的视场改变。
The skilled person would appreciate that although, in FIG. 2, the scintillator 110 moves inside the side shielding, in an alternative embodiment, it may be the side shielding 114 that is arranged to move within the probe head such that the field of view of the detector changes.
例如，后部屏蔽116的尺寸使得侧面屏蔽114可以绕过后部屏蔽以调整探测器的视场。
For example, the rear shielding 116 is sized such that the side shielding 114 can pass around the rear shielding to adjust the field of view of the detector.
闪烁体与侧面屏蔽114相关的移动可以通过任何合适的方式来促进。
The movement of the scintillator relevant to the side shielding 114 can be facilitated by any suitable means.
例如，用于使伽马辐射探测器相对于辐射屏蔽114移动以调整伽马探测器通过探测孔的视场的机构可以包括锁定按钮(如通常在笔上发现的按钮)。
For example, the mechanism for moving the gamma radiation detector relative to the radiation shielding 114 to adjust the field of view of the gamma detector through the detection aperture may comprise a latched button (such as is often found on pens).
伽马辐射探测器或侧面屏蔽114可以是弹簧加载的，使得例如伽马辐射探测器或侧面屏蔽最初被布置在伽马辐射探测器具有第一视场(例如，宽FOV)的第一位置，而在弹簧加载机构致动时，伽马辐射探测器或侧面屏蔽114从第一位置移动到伽马辐射探测器具有第二视场(例如，窄FOV)的第二位置。
The gamma radiation detector or the side shielding 114 may be spring loaded such that, for example, the gamma radiation detector or the side shielding is initially arranged in a first position in which the gamma radiation detector has a first field of view (e.g. a wide FOV) and, on actuation of the spring loaded mechanism, the gamma radiation detector or the side shielding 114 is moved from the first position to a second position in which the gamma radiation detector has a second field of view (e.g. a narrow FOV).
如另一个示例，机构可以是螺纹。
As another example, the mechanism may be a screw thread.
例如，壳体可以分为两部分，其中一部分可以相对于握把机械旋转。
For example, the casing can be in two sections, one of which can be mechanically rotating with respect to the grip.
在可旋转壳体和侧面屏蔽之间的内螺纹将把这种旋转转化为屏蔽114的向前或向后移动。
An internal screw thread between the rotatable casing and the side shielding would translate this rotation into forward or backward movement of the shield 114.
同样，可以设想这可以使用第二外科手术工具来完成，并且两个或更多个稳定位置被限定。
Again, it can be envisaged this can be done with a second surgical tool and that two or more stable positions are defined.
为了促进旋转，在壳体上可以包括抓握特征(例如，两个纹理平面(flats))。
To facilitate the rotation gripping features can be included on the casing (for example, two textures flats).
本文描述的实施例都允许用户快速有效地定位体腔中的辐射源。
The embodiments described herein all allow a user to locate a source of radiation in a cavity quickly and efficiently.
虽然一些实施例通过使用附加的探测器来实现，但是其他实施例通过改善对背景辐射的屏蔽来实现。
While some embodiments do so by using additional detectors, others do so by improved shielding against background radiation.
然而，本文描述的实施例可以以任何合适的方式组合。
However the embodiments described herein may be combined in any suitable way.
由于对用于穿过套管针的腹腔镜探针102的外径的固定限制，对于静态辐射屏蔽来说，在侧面排斥(rejection)和灵敏度之间存在权衡，因为侧面屏蔽深度/厚度制约了伽马辐射探测器的尺寸，例如，闪烁体的尺寸。
Due to the fixed limit on the outer diameter of the laparoscopic probe head 102 for passing through a trocar, for static radiation shielding there is a trade-off between side rejection and sensitivity as the side shielding depth/thickness constrains the size of the gamma radiation detector, for example the size of a scintillator.
发明人已经认识到，为了获得良好的信号，具有>1000的排斥比率是有益的，且因此，例如，如果套管针具有12mm的直径，那么对于6mm的辐射屏蔽，可以使用仅3mm半径的闪烁体。
The inventors have recognized that to achieve a good signal it is beneficial to have a rejection ratio of >1000 and so, for example, if a trocar has a diameter of 12 mm, then for 6 mm of radiation shielding a scintillator of only 3 mm radius may be used.
