50kV X線ジェネレーター

スペルマンのPMXは、FFDMとDBTを含むマンモグラフィー用に特別設計された高性能X線ジェネレーターです。2および3ポイント露光モードおよび前露光のあるスマートAECを備えています。

PMXは、5kW高周波X線ジェネレーターであり、デュアルフィラメント電源と、デュアルスピードX線管スターターと統合されています。 PMXの卓越した電力変換テクノロジーとインバーター設計により、安定かつ正確なX線管高電圧を高速の立ち上がり・立ち下がり時間で提供できます。

PMXのスムーズなシステム統合は、RS-232とオプションのイーサネットデジタルインターフェイス、ロード済みX線管パラメーター、簡単アクセスインターロックとI/O接続、そして内部ジェネレーター診断機能を使用して達成されます。オプションのGUIユーティリティソフトウェアも内部システム統合を支援するために提供可能です。
