5kW Рентгеновские генераторы для маммографии
Система VMX от компании Spellman задает новый стандарт высокопроизводительных и экономичных рентгеновских генераторов для маммографии. Разработка VMX проводилась для создания встраиваемого высокопроизводительного устройства с дополнительными функциями, при создании которого не придется жертвовать критически важными техническими характеристиками, чтобы обеспечить соответствие неуклонно падающим ценовым ориентирам.
Пиковая мощность этого высоковольтного устройства (5 кВт при 40 кВ) в сочетании с двухфокусной трубкой и источником питания постоянного тока катодной нити обеспечивает сокращение времени нарастания импульса, а также стабильность и точность токов эмиссии в рентгеновской трубке. Зона высокого напряжения с твердотельной изоляцией исключает риски, связанные с маслом, а также позволяет сократить негативное влияние влажности воздуха и его загрязненности на работу устройства.
Универсальность интерфейсов обеспечивается за счет цифровых интерфейсов RS-232 и Ethernet (опция). Система VMX оснащена двухскоростным стартером с функциями разгона и экстренной остановки, которые пользователь может настроить с помощью цифрового интерфейса. Компактная, полнофункциональная, недорогая система VMX от компании Spellman — это новое поколение рентгеновских генераторов для маммографии.
