Perancangan perangkat kedokteran nuklir untuk diagnosis fungsi kelenjar gondok berbasis probe

The design of a probe-based nuclear medicine device serves to diagnose thyroid function. The device design comprises a nuclear instrumentation, mechanical, and software system. The nuclear instrumentation system consists of a detection module and a spectrometry module. The detection module consists of a 2M2 NaITl detector as a probe, preamplifier, high voltage and low voltage. The spectrometry module consists of an amplifier, a single-channel analyzer and a counter timer with its DAC. The design of the mechanical system consists of a collimator, collimator holder, collimator holder arm, main body, base, and nuclear instrumentation system box. Software design using visual net programming with interfacing devasys usb. Tests are carried out on a laboratory scale and determine the percentage of capture of radioactive sources. Laboratory scale testing refers to the IAEA technical documents 602 and 363. The testing of the percentage of capture of radioactive sources was using I-131. The test results show that the lower the activity of the standard source, the smaller the percentage uptake of the thyroid gland.
