Spellman CCT Series | CT X-Ray Generators
Spellman High Voltage has been designing, manufacturing and providing CT generators for OEM customers for over three decades. We have unrivaled experience being the first provider of a CT generator used in a commercially available continuous rotating CT scanner in 1985. Since then Spellman has enhanced performance and developed new CT generators year after year, setting the standard for CT generator technology.
Spellman’s CCT series of CT generators provide a unique combination of performance and price. Ideally suited for the economy 16 slice CT scanner, this generator has the ability to be scaled from 32kW to 50kW. Its compact size and unique bend makes it suitable for small footprint gantry designs. Designed to easily pair with many off the shelf CT tubes.

Range: 60kV to 140kV (bipolar, 30kV to 70KV)
Accuracy: ±0.5% of setting
Range: 10mA to 420mA, 50kW maximum.
10mA to 420mA, 50kW maximum.
10mA to 420mA, 50kW maximum.
Auto reversible via front panel switch
Type: Two filament outputs, large and small
Voltage/Current: 15Vac (30kHz-40kHz) @ 0-6A maximum, referenced to cathode output
Power:Maximum mA: 420mA, 50kW maximum
Maximum kV: 140kV, 50kW maximum
Maximum mA: 350mA, 42kW maximum
Maximum kV: 140kV, 42kW maximum
Maximum mA: 275mA, 32kW maximum
Maximum kV: 140kV, 32kW maximum
Type: Dual Speed Starter
Compatibility: All industry standard X-Ray tubes
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
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 |
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
High Voltage Input:
3 pin 75kV Federal Standard (Cathode, Large, Small)
High Voltage Output:

Number of Grids:
One, switched between “Zero” (0V≥Vg-c ZERO ≥ -10V) and “Cutoff” (Vg-c CUTOFF = -4kV±10% @ steady state)
