醫療儀器解決方案:無磁性同軸連接器

佳楠提供許多系列的無磁性同軸連接器,包括 SMA、SMA 27G、MCX、MMCX、SMB 和 SMT 系列。
無磁性同軸連接器主要是為磁振造影MRI 醫療設備需求而創建的,因為MRI相關設備非常需要無磁性干擾這個特性。在生產上除了對材料和電鍍的選用十分嚴謹,還需要嚴格控制的生產和檢驗程序,才能確保製造出來的無磁性同軸連接器的品質和性能能夠符合醫療應用需求。

 

快速導讀:

 

 

為什麼我需要無磁性同軸連接器?

磁振造影(Magnetic Resonance Imaging, MRI),原名為核磁共振(Nuclear Magnetic Resonance, NMR),是一種利用強力磁場和射頻波,結合電腦技術生成人體橫截面圖像的非侵入性成像技術。透過 MRI 儀器,臨床醫師能有效檢查和診斷人體內部結構與病變,且對患者無輻射傷害。

現代醫療診斷工作高度依賴 MRI 儀器。在某些情況下,若使用磁性材料製成的組件,可能會干擾磁場穩定性,進而影響圖像品質。低品質的影像可能導致診斷失誤,甚至引發不當治療。

磁場的均勻性和信噪比是影響 MRI 圖像品質的關鍵因素,因此選擇無磁性的金屬作為材料對於 MRI 儀器的性能非常重要。

任何磁性成份或材料都有可能干擾磁場的均勻性,進而降低成像的品質。為了確保成像精準度,MRI 儀器中使用的同軸連接器、電纜及電容器等組件都應該要避免採用磁性材料。

隨著磁振造影MRI 技術不斷進步,佳楠對低磁化率的無磁性連接器也持續進行相應改進以滿足醫療產業需求。不僅僅是醫療產業,我們還發現無磁性電鍍技術也適用於一些需要無磁特性的其他產業,如WIFI通訊、天線和測量設備。

佳楠是如何生產製造無磁性同軸連接器的?

與一般市場上普遍由黃銅或鎳材料製成的標準同軸連接器不同,無磁性同軸連接器的製成通常會使用低磁性金屬,例如合金,如鈹銅、銀或白青銅。含有微量鐵的不銹鋼、黃銅或鎳可能會產生磁性,對無磁性同軸連接器而言並不是理想的材料選項。

佳楠選用鈹銅和優質無磁性電鍍製作無磁同軸連接器,藉此消除磁力影響,並同時滿足磁振造影MRI和醫療產業的嚴格製造要求。


佳楠根據嚴格的品質控管程序,在嚴密控制的生產和檢驗過程中製造無磁性同軸連接器,並且在一個乾淨的工作環境中進行加工和組裝過程,以防止任何潛在磁性因素,干擾影響無磁性連接器的磁特性卓越表現。
