Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
160 words
A radiation computed tomography apparatus for obtaining a tomographic image of a patient, comprising: a couch which is movable in a predetermined direction; a top board which carries the patient and is slidably arranged on said couch; a gantry which has an opening and acquires projection data of the patient by guiding the patient carried on said top board into the opening; reconstruction means for reconstructing the tomographic image of the patient by reconstructing the projection data acquired by said gantry in real-time; display means for displaying the tomographic image of the patient reconstructed by said reconstruction means in real-time; detecting means for detecting at least a direction of an external force applied to one of said top board and said gantry; and means for driving the one of said top board and said gantry, to which the external force is applied, in the direction of the external force on the basis of a detection value of said detecting means.
Claim 2
Dependent Claim
160 words
A radiation computed tomography apparatus for obtaining a tomographic image of a patient, comprising: a couch which is movable in a predetermined direction; a top board which carries the patient and is slidably arranged on said couch; a gantry which has an opening and acquires projection data of the patient by guiding the patient carried on said top board into the opening; reconstruction means for reconstructing the tomographic image of the patient by reconstructing the projection data acquired by said gantry in real-time; display means for displaying the tomographic image of the patient reconstructed by said reconstruction means in real-time; detecting means for detecting at least a direction of an external force applied to one of said top board and said gantry; and means for driving the one of said top board and said gantry, to which the external force is applied, in the direction of the external force on the basis of a detection value of said detecting means.
Claim 3
Dependent Claim
29 words
An apparatus according to claim 1, further comprising: scan means for scanning the patient while changing a slice width and a slice position upon acquisition of the projection data.
Claim 4
Dependent Claim
33 words
An apparatus according to claim 2, further comprising adjusting means, arranged on or near said gantry, for adjusting a photographing condition of the patient for obtaining a predetermined tomographic image of the patient.
Claim 5
Dependent Claim
43 words
An apparatus according to claim 3, wherein said couch is arranged on a first side surface side of the opening, and said adjusting means is arranged on or near said gantry on a second side surface side opposite to the first side surface.
Claim 6
Dependent Claim
31 words
An apparatus according to claim 3, wherein said gantry and said adjusting means respectively include transmission/reception means and transmit/receive data using said transmission/reception means by one of wireless and wired methods.
Claim 7
Dependent Claim
19 words
An apparatus according to claim 2, wherein said display means is arranged at least on or near said gantry.
Claim 8
Dependent Claim
15 words
An apparatus according to claim 6, wherein said display means is arranged on said gantry.
Claim 9
Dependent Claim
31 words

Claim 10
Dependent Claim
29 words
An apparatus according to claim 6, further comprising goggles which can be fixed to a head of an operator, and wherein said display means is arranged in said goggles.
Claim 11
Dependent Claim
28 words
An apparatus according to claim 1, wherein said gantry has a radiation path at a position separated from said couch with respect to a center of said gantry.
Claim 12
Dependent Claim
19 words
An apparatus according to claim 1, further comprising gantry rotation means for rotating said gantry about a vertical axis.
Claim 13
Dependent Claim
33 words
An apparatus according to claim 1, wherein said gantry has a radiation path movable along an axis of the opening, further comprising gantry rotation means for rotating said gantry about a vertical axis.
Claim 14
Dependent Claim
135 words
A radiation computed tomography apparatus for obtaining a tomographic image of a patient, comprising: a top board which carries the patient; a gantry which has an opening and radiation path arranged in the opening, and acquires projection data of the patient by guiding the patient carried on said top board into the opening, wherein the radiation path is arranged near an opposite side of said gantry opposite to the side to which the patient is guided; detecting means for detecting at least a direction of an external force applied to one of said top board and said gantry: and means for driving one of said top board and said gantry, to which the external force is applied, in the direction of the external force on the basis of a detection value of said detecting means.
Claim 15
Dependent Claim
135 words
A radiation computed tomography apparatus for obtaining a tomographic image of a patient, comprising: a top board which carries the patient; a gantry which has an opening and radiation path arranged in the opening, and acquires projection data of the patient by guiding the patient carried on said top board into the opening, wherein the radiation path is arranged near an opposite side of said gantry opposite to the side to which the patient is guided; detecting means for detecting at least a direction of an external force applied to one of said top board and said gantry: and means for driving one of said top board and said gantry, to which the external force is applied, in the direction of the external force on the basis of a detection value of said detecting means.
