X-ray CT apparatus and data detection system for X-ray CT apparatus
View Patent ↗According to one embodiment, a data detection system for an X-ray CT apparatus includes a data acquisition circuit and a connection structure. The data acquisition circuit includes at least one row of X-ray detection elements arrayed in a channel direction. The data acquisition circuit is configured to acquire data required for generating X-ray CT image data corresponding to the at least one row of the X-ray detection elements. The connection structure is configured to connect the data acquisition circuit with another data acquisition circuit directly or indirectly in a row direction.
1. A data detection system for an X-ray CT apparatus comprising:
a data acquisition circuit, including at least one row of X-ray detection elements arrayed in a channel direction, and configured to acquire data required for generating X-ray CT image data corresponding to the at least one row of the X-ray detection elements; and
a connection structure configured to connect said data acquisition circuit with another adjacent data acquisition circuit directly or indirectly in a row direction, the X-ray detection elements installed in said data acquisition circuit shifting from X-ray detection elements installed in the another adjacent data acquisition circuit in the channel direction; and
an adjustment structure configured to adjust a shift amount in the channel direction between said data acquisition circuit and the another adjacent data acquisition circuit.
2. The data detection system for the X-ray CT apparatus of claim 1 ,
wherein said data acquisition circuit includes a platy circuit board whose thickness direction is different from a rotation direction of said data acquisition circuit.
3. The data detection system for the X-ray CT apparatus of claim 1 ,
wherein said data acquisition circuit has X-ray detection elements, each having photodiodes arranged in an incident direction of an X-ray.
4. The data detection system for the X-ray CT apparatus of claim 1 ,
wherein said data acquisition circuit includes a platy circuit board,
a photodiode installed in each of the X-ray detection elements is on the platy circuit board, and
a boundary face between the photodiode and the platy circuit board being perpendicular to the row direction.
5. The data detection system for the X-ray CT apparatus of claim 1 ,
wherein said data acquisition circuit includes plural X-ray detection elements in the row direction.
6. A data detection system for the X-ray CT apparatus of claim 1 , including:
said data acquisition circuit; and
the another adjacent data acquisition circuit connected with said data acquisition circuit in the row direction by said connection structure.
7. An X-ray CT apparatus comprising:
said data detection system of claim 1 ;
an X-ray tube configured to expose an X-ray to an object; and
a data processing circuit configured to generate the X-ray CT image data based on projection data of the object acquired by said data detection system.
