Small, gamma-sensitive, cadmium-telluride [CdTe(C1)] detectors are evaluated for biotelemetry of the local clearance of an injected radioactive depot in tissue. The lateral displacement dependence and depth dependence are determined with 99mTc as radiation source. Perspex is used as attenuation and scattering medium. With 133Xe injected into subcutaneous tissue the effect of a geometrical adjustment of the CdTe(C1) detector prior to measurement is studied. Examples of 133Xe disappearance curves are shown during rest and ergometry bicycling.
对小型、对γ射线敏感的碲化镉[CdTe(C1)]探测器进行评估，用于对注入组织中的放射性储库在局部清除情况进行生物遥测。以99mTc作为辐射源，确定横向位移依赖性和深度依赖性。使用有机玻璃作为衰减和散射介质。将133Xe注入皮下组织，研究在测量前对CdTe(C1)探测器进行几何调整的效果。展示了静息和功率计骑行期间133Xe消失曲线的示例。
