Description

[0001]
[Industrial application fields]
The present invention relates to an image capturing apparatus that captures a positioning image before capturing a continuous tomographic image or a single slice tomographic image of a patient.
[0002]
[Prior art]
In a relatively large hospital in the past, operations are being subdivided. For example, in diagnostic imaging work, doctors who have been diagnosed and treated in the past used to interpret images taken by radiation technicians who are qualified to handle radiation, but in recent years, they have been taken by radiation technicians. A specialized interpreting doctor interprets these images, and doctors have come to perform diagnosis and treatment by looking at the interpretation results (interpretation report) by the interpreting doctor.
[0003]
A series of work flows related to conventional image diagnosis will be described below. In the case of an X-ray computer tomography apparatus (X-ray CT), this operation is started when a doctor issues an imaging request form to a radiologist. In the imaging request form, information related to imaging conditions such as an imaging region is written in addition to patient-specific information such as a patient name and patient age. The radiologist receives this imaging request and drafts an imaging plan. First, a positioning projection image called a scanogram is taken. Then, the radiologist sets each position of the continuous section through the scanning console while watching the scanogram alone or according to the doctor's instruction. As a result, conditions such as each position of the continuous step surface and pedestal tilt angle (tilt angle) are automatically set in the photographing apparatus by the CPU in the console. In addition to this position information, conditions such as an X-ray tube voltage, an X-ray tube current, a distance between the X-ray tube and the subject (X-ray shift amount), a reconstruction function, and the number of imaging pulses are set. .
[0004]
Through such an imaging plan, imaging (scanning) is actually executed, and projection data in all angles is collected for each cross section. A CT image (tissue tomographic image) of each cross section is reconstructed by a computer using the projection data collected in this manner, and these CT images are sent to an interpretation workstation in the interpretation room and used for interpretation. The interpretation results are collected in an interpretation report and conveyed to the doctor who made the imaging request. The doctor makes a diagnosis while referring to the interpretation report and decides the treatment policy.
Such a series of flows is the same even in the magnetic resonance imaging apparatus.
[0005]
[Problems to be solved by the invention]
In such a conventional flow of image diagnosis, due to lack of information due to, for example, a shift between a lesioned part and an imaging section at the interpretation stage, a situation occurs in which the scan plan must be changed and imaging must be performed again. Sometimes. This is thought to be mainly due to the fact that the interpreting doctor does not intervene at all in the planning of the scan plan. Repeated imaging results in increased patient throughput. At present, there has not been established an image capturing apparatus configured in accordance with a work flow that realizes a rapid image diagnosis work while interfering with an interpreting doctor in making a scan plan.

Description of the X-ray CTs 2 and 3 and the image interpretation workstations 5 and 6 having the same configuration as that shown in FIG. The X-ray CT1 is roughly divided into a gantry 10, a console 11, and a high voltage generator 12. A gantry 10 which is a structure for collecting projection data of all angles of a photographing section is a ring-shaped gantry (not shown) supported by a pedestal mechanism so as to be tiltable and rotatable with respect to a vertical axis. , A gantry drive control device 13, an imaging system 14, a couch (not shown), a couch drive control device 15, and a data collection device 16. The gantry drive control device 13 rotationally drives the rotating gantry. The imaging system 14 is composed of an X-ray tube and a multi-channel X-ray detector array that are mounted on a rotating mount so as to face each other with an imaging region interposed therebetween. When tube power is supplied from the high voltage generator 12 to the X-ray tube, the X-ray is blown out in a fan shape from the X-ray tube. The bed drive control device 15 drives the bed and inserts or inserts the subject into the imaging region. The data acquisition device 16 individually amplifies detection signals detected in each channel of the multi-channel X-ray detector array and converts them into digital signals.
[0014]
When scanning a scanogram, the rotating gantry is stopped, and the subject is continuously moved along the body axis direction by the bed during the continuous operation of the X-ray tube and the multi-channel X-ray detector array. Thereby, a scanogram such as an X-ray projection image viewed from one direction is taken. On the other hand, in the case of imaging for collecting projection data at all angles, the rotating base is rotated, and the subject is moved along the body axis by the bed during continuous or intermittent operation of the X-ray tube and the multi-channel X-ray detector array.

Further, a scan operation of a scanogram is performed by the radiologist through the input device 21.
[0016]
Scanogram data shot by the shooting system 14 is sent to the network line 7 via the CPU 20 and the LAN interface 22.
The interpretation workstation 4 includes a CPU 23, an image display device 24, a LAN interface 25 for the network line 7, and an input device 26 such as a mouse and a keyboard. The scanogram sent from the X-ray CT 1 via the network line 7 is displayed on the image display device 24 via the CPU 23. On the scanogram, the position of the imaging cross section is set as, for example, a plurality of parallel line cursors via the input device 21 by the operation of the interpretation doctor. The plurality of line cursors are arranged at arbitrary positions desired by the interpreting doctor along the body axis of the subject and at any inclination angle desired by the interpreting doctor with respect to the vertical axis orthogonal to the body axis of the subject (Corresponding to the tilt angle) and an arbitrary interval (corresponding to the slice pitch) desired by the interpreting physician.

FIG. 5 is a diagram showing a display screen of the image display device of the image interpretation workstation.
[0019]
First, the operation of this embodiment will be described with reference to FIG. Before actually starting the scanning of the continuous section, the radiologist performs a scanogram imaging operation via the input device 21 of the console 11. That is, the rotating gantry is stopped, and the subject is continuously moved along the body axis direction by the bed during the continuous operation of the X-ray tube and the multi-channel X-ray detector array. Thereby, a scanogram such as an X-ray projection image viewed from one direction is taken. The scanogram data is sent to the interpretation workstation 4 (or 5 or 6) on which the interpretation doctor stands by via the CPU 20 of the console 11, the LAN interface 22, and the network line 7. The scanogram is displayed on the image display device 24 via the CPU 23 of the image interpretation workstation 4. The interpreting doctor makes a scan plan while looking at the scanogram. That is, each position of the continuous cross section is set on the scanogram as a plurality of parallel line cursors as shown in FIG. The plurality of line cursors are arranged at arbitrary positions desired by the interpreting doctor along the body axis of the subject and at any inclination angle desired by the interpreting doctor with respect to the vertical axis orthogonal to the body axis of the subject (Corresponding to the tilt angle) and an arbitrary interval (corresponding to the slice pitch) desired by the interpreting physician.
[0020]
In addition to the position of this radiographing section, the interpreting physician via the input device 21 of the interpretation workstation 4 uses the X-ray tube voltage, the X-ray tube current, the distance between the X-ray tube and the subject (X-ray shift amount), Each condition such as a configuration function and the number of imaging pulses is set. The imaging conditions set by the interpretation workstations 4, 5, 6 are transferred to the CPU 20 of the X-ray CT 1 via the CPU 23, the LAN interface 25, and the network line 7. Under the overall control of the CPU 20 according to the photographing conditions, the high voltage generator 12 and the units 13, 14, 15, and 16 of the gantry 10 operate in association with each other. In other words, the rotating gantry is set to be tilted with respect to the vertical axis by the tilt angle, the rotating gantry is continuously driven to rotate, and the X-ray tube and the multi-channel X-ray detector array are operated continuously or intermittently. The subject is intermittently moved at the slice pitch along the body axis direction by the bed. As a result, full-angle projection data for each cross section planned for photographing is collected. The projection data collected in this way is sent to the image reconstruction device 17, and a tomographic image of each cross section of the continuous cross section is reconstructed.
[0021]
The tomographic image data of each cross section is transferred to the interpretation workstation 4 (or 5 or 6) on which the interpretation doctor who has set the imaging conditions stands by via the CPU 20 of the console 11, the LAN interface 22, and the network line 7. Is done. The data of the tomographic images of these cross sections are received via the CPU 23 of the interpretation workstation 4 and are displayed on the image display device 24 one by one or in batches. The interpretation doctor interprets the display image. The interpretation results are compiled into an interpretation report and reported to the doctor who requested the imaging as an interpretation result report.
[0022]
Next, FIG. 3 will be described with reference to FIG. The doctor (physician) explains the imaging to the patient, instructs the nurse to take care when imaging, and requests the radiographer to take an image by issuing an imaging request form. Ask for interpretation.
[0023]
The nurse who received the instruction from the doctor places the patient on the bed in the photographing room as preparation for photographing, and fixes the patient to the bed in order to avoid movement as much as possible. The radiologist who has received the imaging request form from the doctor first operates the X-ray CT1 to capture a scanogram. The scanogram data is transferred from the X-ray CT1 to the interpretation workstation 4 on which the interpretation doctor requested to interpret by the doctor waits. The interpreting physician operates the input device 26 to set the imaging conditions. That is, a plurality of line cursors are operated on the scanogram via the input device 21 by the operation of the interpreting doctor, on the scan axis, at a desired position of the interpreting doctor along the vertical axis perpendicular to the body axis of the subject. Are set to an arbitrary inclination angle (corresponding to the tilt angle of the gantry) desired by the interpretation doctor and to an arbitrary interval (corresponding to the slice pitch) desired by the interpretation doctor. Further, a plurality of plans can be performed as the same plan by changing an arbitrary pitch and other conditions.
[0024]
In addition to the position of this radiographing section, the radiographing doctor uses the input device 21 of the radiographing workstation 4 to read the X-ray tube voltage, X-ray tube current, and distance between the X-ray tube and the subject (X-ray shift amount). Each condition such as the reconstruction function and the number of imaging pulses is set.
[0025]
The imaging conditions set in this way are transferred to the CPU 20 in the console 11 of the X-ray CT1, and imaging is executed under the overall control of the CPU 20, and the tomographic images of the respective sections are reconstructed.
[0026]
When the radiographer finishes the radiography, the radiographer informs the nurse who has been waiting in a place where the bomb is not exposed during the radiographing period. The nurse releases the patient from the X-ray CT1.
The interpretation doctor interprets each tomographic image transferred to the interpretation workstation 4 and reports the interpretation result to the doctor as an interpretation report.
[0027]
The doctor makes a diagnosis based on the tomographic image and the interpretation result, and makes a treatment plan.
As described above, according to the present embodiment, an interpreting doctor can easily intervene in setting of imaging conditions, that is, planning of an imaging plan. Accordingly, since the number of re-imaging due to lack of information at the interpretation stage is reduced, patient throughput can be shortened. In addition, since the interpreting doctor can set the imaging conditions while staying in the interpretation room, even if the interpreting doctor intervenes in setting the imaging conditions, it is possible to avoid a long series of flow of image diagnosis. In addition, since the radiographing doctor can set imaging conditions while staying in the radiology room, imaging can be performed quickly even when patient imaging is performed again.
