Publication number: 20150327816Abstract: According to an embodiment, an X-ray CT apparatus comprises a bed reciprocating member, setting circuitry, determination circuitry, and control circuitry. The bed reciprocating member reciprocally moves the top along the body axis direction of the object. The setting circuitry sets an imaging range in the above helical scanning.
