High-Precision Dual Focal Spots: Seamlessly balance ultra-sharp spatial resolution and heavy thermal loading. Equipped with precision-aligned small and large focal spots, this tube assembly delivers crisp edge definition for intricate bone structures while maintaining the raw thermal headroom needed for dense thoracic and bariatric imaging.
-
Advanced Radiation Shielding Casing: Absolute safety for patients and clinicians. The robust, powder-coated cylindrical metal housing is meticulously lined with high-density lead backing to limit stray radiation leakage to levels well below strict international IEC and FDA compliance thresholds.
-
Flawless High-Voltage Receptacle Integration: Standardized power delivery. Featuring clearly defined, heavily insulated positive and negative high-voltage cable connection ports , our housing prevents dielectric breakdown or high-voltage arcing even when driven at maximum peak kilovoltage (kVp).
-
Superior Thermal Bellows Protection: The assembly incorporates an internal high-efficiency oil expansion bellows mechanism. If continuous high-volume scanning causes extreme oil expansion, the integrated safety circuit cuts system exposure commands instantly, saving the tube insert from terminal heat damage.
-
Global Interchangeability Matrix: Designed to slash aftermarket maintenance overhead. Our universal mounting configuration and center port design align perfectly with industry-standard replacement specifications, offering a highly reliable, cost-effective alternative to expensive original equipment manufacturer components.

❓ Crucial B2B Component Procurement Q&A
Q1: Looking at the design in, is the stator coil included within the housing center, and what is its compatibility with external starters?
A: Yes, the housing comes pre-equipped with an internal stator coil wrapped around the rotor neck area to drive the internal rotating anode. The electrical impedance and phase configurations are designed to be universally compatible with the vast majority of high-frequency X-ray generators and standalone electronic starters available on the global market.
Q2: How does your factory handle gas bubble elimination and oil purity during the housing filling process?
A: Every tube assembly shown in undergoes a strict vacuum oil-filling procedure. The high-dielectric insulating oil is completely degassed and dehydrated before injection under ultra-high vacuum conditions. This absolute extraction of micro-bubbles guarantees that the housing maintains its dielectric integrity and prevents internal electrical short-circuits at 150kV.
Q3: Can we purchase the raw housing assembly shell as seen in to load our own custom tube inserts, or do you only sell fully enclosed completed assemblies?
A: We accommodate both supply chains. We operate a dedicated foundry and assembly plant that can supply either empty, unsealed lead-lined housings equipped with stator coils and cable sockets, or completely finished, vacuum-sealed, and factory-calibrated completed tube units ready to plug directly into a clinic’s system.
Q4: Is the mounting flange around the central ray window adjustable to fit different types of electronic automatic collimators?
A: The main window interface featured in the center of uses an industry-standard 4-bolt or 6-bolt machined mounting flange. This physical pattern allows direct, centered attachment of most standard manual or motorized medical collimators without requiring custom adapter plates or adjustments.
