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)
