The Development of ESR-CT Apparatus for Biological Samples and the Application to Diagnosis of Intractable Diseases such as Tumor

我们研制了几种X波段ESR-CT(ESR-CT)成像仪，并在个人计算机上通过GP-IB接口总线进行了自动测量，如下所示：(1)具有针孔TE_(102)模腔和快速扫描线圈的ESR成像仪。(2)具有薄TM_(110)模腔和三维ESR成像线圈的ESR_CT装置。(3)具有小型TM_t；01&GT；的ESR CT装置。Delta型腔体和ESR成像线圈。(4)方便、教育的三维ESR-CT设备。利用这些设备，首次观察到了小鼠B16黑色素瘤的ESR成像。丙氨酸和蔗糖(蔗糖)的三维ESR成像板已被开发为剂量计，并应用于测量接收到的放射性强度。

We have developed several X-band ESR-CT (ESR Imaging ) Apparatus and automatically measured by using a personal computer through the GP-IB interface bus shown as follows.(1) ESR imaging apparatus with a pin-hole TE_<102> mode cavity and a rapid scan coil.(2) ESR CT apparatus with a thin TM_<110> mode cavity and 3-dimensional ESR imaging coils.(3) ESR CT apparatus with a small TM_<01> delta mode cavity and ESR imaging coils.(4) convenient and educational 3-dimensional ESR-CT apparatus.Using these apparatus, ESR imaging of melanin in mouse B16 melanoma was observed for the first time. Three dimensional ESR imaging plates of alanine and sucrose (cane sugar) have been developed as dosimeters and applied to measure how much radioactivity is received.
