CT X線ジェネレーター
スペルマンは、30年以上にわたりOEMのお客様向けにCTジェネレーターを設計、製造してきました。1985年に連続回転CTスキャナーに使用されている、CTジェネレーターの最初のプロバイダーとなってから積み重ねてきた、豊富な経験を持っています。それ以来、スペルマンは性能を向上させ、毎年新しい製品を開発し、CTジェネレーター技術の標準を確立しました。
スペルマンのCTジェネレーターのCCTシリーズは、パフォーマンスと価格で独自の組み合わせをご提供いたします。 16スライスCTスキャナーに最適なこのジェネレーターは、32 kWから50 kWまでスケーリングできます。コンパクトなサイズと独自の折れ曲がった形状により、設置面積の小さいガントリー設計に適しています。 多くの既製のCTチューブと簡単にペアリングできるように設計されています。

GRID SPECIFICATIONS
Deflection Grid: The deflection grid (also called the Flying Focal Spot) allows for dynamic movement of the focal spot providing double X sampling which increases effective resolution while decreasing unwanted artifacts.
Type: Deflection grid, single box assembly
Input Power: 24Vdc, ±10% @ 4.2A maximum, negative input ties to chassis ground internally
Connectors:
High Voltage Input: 3 pin 75kV Federal Standard (Cathode, Large, Small)
High Voltage Output: 4 pin 75kV CA7 (Cathode, Large, G1, G2)
Number of Grids: 2 grids, switching out of phase Bandwidth: DC to 5kHz
Output Voltage: 0V to -4KV, from grid to cathode. User input will command the bi-level grids to switch between adjustable voltages, VLOW and VHI. The two grids switch out of phase: If G1 is at VLOW, G2 will be at VHI and vice versa. The VLOW and VHI levels for G1 and G2 are independently adjustable from 0 to -4KV but VLOW range is constrained by: |VLOW | ≤ | VHI |
Cutoff Grid:
A cutoff grid truncates the high voltage at the end of the X-Ray exposure, reducing patient radiation dosing that does not contribute to the imaging process.
Type: Cutoff grid, single box assembly Input Power: 24Vdc, ±10% @ 0.75A maximum, negative input ties to chassis ground internally
Connectors:
High Voltage Input:
3 pin 75kV Federal Standard (Cathode, Large, Small)
High Voltage Output:
4 pin 75kV CA7 (Cathode, Large, G1, G2)
Number of Grids:
One, switched between “Zero” (0V≥Vg-c ZERO ≥ -10V) and “Cutoff” (Vg-c CUTOFF = -4kV±10% @ steady state)
