Description

[Technical Field]

[0001] The embodiments disclosed in this specification and the drawings relate to a medical image diagnostic apparatus and a movement control system for the medical image diagnostic apparatus. [Background technology]

[0002] An X-ray CT (Computed Tomography) device includes a bed on which a patient rests and a gantry that acquires X-ray detection data related to the patient. To move the bed or the gantry, a user such as a doctor or technician operates a button panel with hard buttons.

[0003] To address this issue, consideration has been given to replacing button panels with liquid crystal touch panels in order to improve operability and reduce cleaning time. However, in order to operate the touch panel as intended, users must operate it while looking at it, just like with button panels. In other words, it is difficult for users to operate the touch panel while closely watching the patient's condition. [Prior art documents] [Patent documents]

[0008] Hereinafter, embodiments of a medical image diagnostic apparatus and a movement control system for a medical image diagnostic apparatus will be described in detail with reference to the drawings.

[0009] An X-ray CT device equipped with an operation panel according to an embodiment will be described in detail below with reference to the drawings. Note that the operation panel according to the embodiment can also be equipped in a plain X-ray device. In the following description, components having substantially the same functions and configurations are designated by the same reference numerals, and redundant description will be given only when necessary.

[0010] [First embodiment] 1 is a schematic diagram showing an example of the configuration of an X-ray CT apparatus 1 according to the first embodiment. The X-ray CT apparatus 1 is an example of a medical image diagnostic apparatus. As shown in FIG. 1, in the first embodiment, the rotation axis of the rotating frame 13 in a non-tilted state or the longitudinal direction of the tabletop 33 of the bed apparatus 30 is defined as the z-axis direction, an axial direction perpendicular to the z-axis direction and parallel to the floor surface is defined as the x-axis direction, and an axial direction perpendicular to the z-axis direction and perpendicular to the floor surface is defined as the y-axis direction.

[0011] The medical image diagnostic device does not have to be the X-ray CT device 1, but may be an MRI (Magnetic Resonance Imaging) device, a PET (Positron Emission Tomography) device, or the like, as long as it has a movable unit (a stand, a bed).

[0012] The X-ray CT apparatus 1 according to the first embodiment includes a gantry device 10, a bed device 30, and a console device 40. For ease of explanation, in Fig. 1, a plurality of gantry devices 10 are depicted with different orientations above and below on the left side, but in the actual configuration, there is only one gantry device 10.

[0013] The bed device 30 includes a base 31, a bed driving mechanism 32, a top plate 33, and a support frame 34. The subject P to be scanned is placed on the bed device 30. The base 31 is a housing that supports the support frame 34 so that it can move in the vertical direction (y-axis direction). The top plate 33 is provided on the upper surface of the support frame 34 and is a plate on which the subject P is placed. The top plate 33 of the bed device 30 is an example of a movable part and a bed.

[0014] The bed driving mechanism 32 is a motor or actuator that moves a tabletop 33 on which the subject P is placed under the control of the control device 15. The tabletop 33 can be moved in the longitudinal direction (z-axis direction) and vertical direction (y-axis direction) of the tabletop 33 by the bed driving mechanism 32.

[0015] The gantry device 10 includes an X-ray tube 11, an X-ray detector 12, a rotating frame 13, an X-ray high voltage device 14, a gantry base 19, a control device 15, and a data acquisition circuit (DAS: Data Acquisition System) 18.

[0016] The X-ray tube 11 is, for example, a vacuum tube that receives a high voltage power supply from an X-ray high voltage device 14 and irradiates thermoelectrons from a filament toward a target, thereby generating X-rays.

[0017] The X-ray detector 12 includes, for example, an X-ray detection element array in which a plurality of X-ray detection elements are arranged in the channel direction along one arc centered on the focal point of the X-ray tube 11. The X-ray detector 12 detects X-rays that are irradiated from the X-ray tube 11 and pass through the subject P, converts them into electrical signals, and outputs them to the data acquisition circuitry 18.

[0018] The rotating frame 13 is supported so as to be rotatable around its center as a rotation axis. The rotating frame 13 is rotationally driven under the control of the control device 15, and rotates the X-ray tube 11 and the X-ray detector 12 relative to the gantry device 10 and the bed device 30.

[0019] The X-ray high voltage device 14 includes a high voltage generator having electrical circuits such as a transformer and having the function of generating a high voltage to be applied to the X-ray tube 11, and an X-ray control device that controls the output voltage according to the X-rays emitted by the X-ray tube 11.

[0020] The gantry base 19 is a housing that supports the opening of the gantry device 10 in the vertical direction (y-axis direction). The gantry base 19 may include a gantry tilt mechanism 21 that enables the opening facing the bed device 30 to be tilted forward or backward from the vertical direction (y-axis direction). The gantry tilt mechanism 21 is a motor or actuator that tilts the gantry device 10 under the control of the control device 15. The gantry tilt mechanism 21 enables the gantry device 10 to tilt the opening facing the bed device 30 forward or backward from the vertical direction (y-axis direction).

[0021] The control device 15 includes a memory 16 and a processing circuit 150. The control device 15 has a function of controlling the driving of the gantry device 10 and the bed device 30 based on control signals generated by operations on an input interface provided in the console device 40 or the gantry device 10. Operations on the input interface include contact of a detection unit 52 by a user, which will be described later. In response to the control signals, the control device 15 controls the rotation of the rotating frame 13, the tilt of the gantry device 10, and the movement of the bed device 30 and the tabletop 33. The control device 15 may be provided in at least one of the gantry device 10 and the bed device 30, or may be provided in the console device 40. The control device 15 is an example of a control unit.

[0022] The memory 16 stores various processing programs used in the processing circuit 150, data necessary for executing the programs, etc. The memory 16 has a configuration including a processor-readable storage medium such as a magnetic or optical storage medium, or a semiconductor memory.

[0023] The processing circuitry 150 has a dedicated or general-purpose processor, and is a processor that executes a program stored in the memory 16 to realize the processing described below.

[0024] The data collection circuitry 18 includes an amplifier that amplifies the electrical signals output from each X-ray detection element of the X-ray detector 12, and an A / D converter that converts the electrical signals into digital signals. The data collection circuitry 18 generates detection data and transfers the generated detection data to the console device 40.

[0025] The console device 40 includes a memory 41, a display 42, an input interface 43, and a processing circuit 44. The console device 40 performs image processing on the detection data generated by the data acquisition circuit 18 and performs overall control of the X-ray CT apparatus 1. Note that although the console device 40 will be described as being separate from the bed device 30 and the gantry device 10, the bed device 30 and the gantry device 10 may include the console device 40 or some of the components of the console device 40.

[0026] The configurations of the memory 41 and the processing circuitry 44 are the same as those of the processing circuitry 150 and memory 16 of the control device 15, and therefore description thereof will be omitted. The display 42 is a display device realized by, for example, a liquid crystal display, and outputs medical images generated by the processing circuitry 44 and a GUI (Graphical User Interface) for accepting various operations from the user. The input interface 43 is realized by, for example, a keyboard, a mouse, and the like, and accepts various input operations from the user, converts the accepted input operations into electrical signals, and outputs the signals to the processing circuitry 44.

[0027] 2 is a schematic diagram showing an example of the configuration of the X-ray CT apparatus 1 according to the first embodiment. Communication between the panel main body 50 of the operation panel 5 and the bed device 30 will be described with reference to FIG.

[0028] The panel body 50 of the operation panel 5 has a display unit 51 and a detection unit 52. The display unit 51 outputs a GUI (Graphical User Interface) and the like for receiving various operations from the user. The display unit 51 is realized, for example, by a liquid crystal display or the like. The detection unit 52 detects contact by the user at any position. The detection unit 52 is realized, for example, by a touch panel provided on the gantry device 10. The detection unit 52 may be an area on the operation panel 5, or may be a panel (for example, a touchpad) separate from the operation panel 5.

[0029] The operation panel 5 is also configured to be able to communicate with the bed device 30. To this end, the operation panel 5 is provided with a signal generating unit 55, a first communication unit 56, and an antenna 57. The first communication unit 56 is an example of a communication unit. On the other hand, the bed device 30 is provided with a second communication unit 35 and the antenna 36 for communicating with the operation panel 5. The second communication unit 35 is an example of a receiving unit.

[0030] The signal generation unit 55 generates a control signal related to the movement of the tabletop 33 based on contact with, for example, the user's finger detected by the detection unit 52. The control signal includes at least one of the movement direction and movement speed of the tabletop 33. The first communication unit 56 transmits the control signal via the antenna 57. The second communication unit 35 receives the control signal transmitted by the first communication unit 56 via the antenna 36 and transfers it to the processing circuit 150 of the control device 15. The first communication unit 56 and the second communication unit 35 can transmit and receive signals bidirectionally. Transmission and reception between the first communication unit 56 and the second communication unit 35 can use wireless communication such as Bluetooth (registered trademark), for example.

[0031] In the above, a configuration has been described in which the X-ray CT apparatus 1 is provided with the operation panel 5, but there may also be a movement control system for the X-ray CT apparatus 1 in which the X-ray CT apparatus 1 and the operation panel 5 are separate entities. The movement control system includes at least the X-ray CT apparatus 1, a first communication unit 56, a detection unit 52, and a signal generation unit 55. The X-ray CT apparatus 1 includes at least a top board 33, a second communication unit 35, and a control device 15 that controls the movement of the top board 33.

[0032] Then, the first communication unit 56 transmits the control signal to the second communication unit 35. The second communication unit 35 receives the control signal from the first communication unit 56. The control device 15 controls the movement of the tabletop 33 based on the control signal.

[0033] The processing circuit 150 of the control device 15 may be distributed. For example, the processing circuit 150 may be located only in the operation panel 5, or may be built into the gantry device 10. The processing circuit 150 may issue instructions directly to the bed device 30 without going through the console device 40.

[0034] 3 is a diagram illustrating the position of the operation panel 5 relative to the bed device 30 according to the first embodiment. Usually, before starting to acquire examination images, a user such as a technician performs operations to move the tabletop 33 on which the subject P is placed up and down, move the tabletop 33 in the longitudinal direction, and drive the gantry device 10 to tilt forward and backward, in order to position the subject P according to the contents of the examination. Furthermore, at the end of the examination, operations required for the subject P to get off the bed device 30 are performed.

[0035] 3, the antenna 36 is disposed inside the base 31 at a position substantially in the center in the y-axis direction and close to the side surface on the positive side in the x-axis direction. On the other hand, the operation panel 5 is disposed on the upper right side of the gantry 10, or at approximately the 2 o'clock position if the rotating frame 13 is a clock, facing the negative side in the z-axis direction.

[0036] This allows the operation panel 5 to be at an appropriate height, allowing the user to comfortably operate the operation panel 5. Furthermore, the antenna 36 of the bed device 30 and the antenna 57 of the operation panel 5 are positioned so that they can be seen from each other, allowing for good communication.

[0037] 4A and 4B are diagrams showing examples of operations for moving the tabletop 33 according to the first embodiment. FIG. 4A shows an example of a slide operation. FIG. 4B shows an example of a touch operation. The detection unit 52 detects a first contact, which is a contact by the user's finger, and a second contact, which is a contact after the first contact. The control device 15 controls the movement speed of the tabletop 33 based on the first contact and the second contact.

[0038] In FIG. 4, a black circle indicates the position of the first contact, and a white circle indicates the position of the next contact. The first contact is an example of a first contact. The next contact is a contact after the first contact and is an example of a second contact. This is also true in FIG. 5. Note that the position of the first contact indicated by the black circle may be within the area of ​​the detection unit 52.

[0039] As shown in FIG. 4(a), the user first touches the position of the black circle on the detection unit 52 with their thumb, then touches one of the white circles adjacent to the black circle (e.g., the white circle adjacent to the top), and then slides the index finger upward. When the detection unit 52 detects such a sliding operation on the operation panel 5, the signal generation unit 55 generates a control signal indicating, for example, the direction of movement of the tabletop 33 corresponding to the direction of the user's next touch relative to the position of the user's first touch, and the speed of movement of the tabletop 33 corresponding to the user's sliding operation. The first communication unit 56 transmits a control signal to the control device 15 via the bed device 30, including an instruction to move the tabletop 33 upward in the y-axis direction at a speed slower than a predetermined speed. The sliding operation on the operation panel 5 corresponds to the slow movement of the tabletop 33.

[0040] Note that up, down, in, and out in the detection unit 52 in Figure 4 correspond to the movement directions of the top plate 33. That is, the up direction corresponds to the upward direction in the y-axis direction (ascending direction). The down direction corresponds to the downward direction in the y-axis direction (descending direction). The in direction corresponds to the direction in which the top plate 33 enters the rotating frame 13 in the z-axis direction. The out direction corresponds to the direction in which the top plate 33 leaves the rotating frame 13 in the z-axis direction. This is also true in Figure 5.

[0041] As shown in FIG. 4(b), the user first touches the position of the black circle on the detection unit 52 with the thumb, and then touches one of the white circles spaced from the black circle with the index finger (for example, the white circle further away from the front). When the detection unit 52 detects such a touch operation on the operation panel 5, the signal generation unit 55 generates a control signal related to the speed of movement of the tabletop 33 corresponding to the user's touch operation. The signal generation unit 55 generates a control signal related to the direction of movement of the tabletop 33 corresponding to the direction of the user's next touch, based on the position of the user's first touch. The first communication unit 56 transmits a control signal including an instruction to move the tabletop 33 toward the front in the z-axis direction at a speed faster than a predetermined speed to the control device 15 via the bed device 30. The touch operation on the operation panel 5 corresponds to fast movement of the tabletop 33.

[0042] Conventional operation panels have one fast button and four slow buttons for slow operation in each direction. When the user presses the fast button and then any of the four slow buttons, fast operation is activated. The touch operation according to the first embodiment applies the conventional fast operation with two actions.

[0043] The user operates the operation panel 5 while gazing at the subject P without looking at it, but must avoid any unintended or erroneous operation. According to the first embodiment, since both the slide operation and the touch operation include two actions, the user must be aware of the operation, which can prevent erroneous operations. In this case, the operation of touching the detection unit 52 of the operation panel 5 with the thumb once as the first contact is important.

[0044] In relation to the initial touch, since the user operates the operation panel 5 without looking at it, it becomes difficult for the user to grasp the reference position, which is the position to be touched first. However, if the reference position in the detection unit 52 is fixed, the user will have to search for that reference position, making operation even more difficult. According to the first embodiment, the point where the thumb first touches is set as the reference position, and the direction and speed of movement are determined by the point where the index finger next touches, so that user operability that matches the image of moving the tabletop 33 can be realized.

[0045] According to the above, the user can perform an operation to move the top board 33 without visually checking the detection unit 52 which is a touch panel.

[0046] Second Embodiment 5A and 5B are diagrams showing examples of operations for switching the movement speed of the tabletop 33 according to the second embodiment. Fig. 5A shows an example of switching the movement speed of the tabletop 33 based on the distance between two contact positions. Fig. 5B shows an example of switching the movement speed of the tabletop 33 based on the number of contact points between the two contacts. Fig. 5C shows an example of a flick operation.

[0047] The detection unit 52 of the operation panel 5 detects the position of the first contact and the position of the next contact and determines the distance between the positions of the first contact and the next contact. The signal generation unit 55 generates a control signal related to the movement speed of the top 33 based on the distance between the positions of the first contact and the next contact. For example, the signal generation unit 55 may control the movement speed of the top 33 so that the greater the distance, the greater the movement speed of the top 33. As shown in FIG. 5(a), when comparing the distance between the black circle representing the position of the first contact and the white circle representing the position of the next contact, the distance in the downward direction is greater than the distance in the upward direction. Therefore, the speed at which the top 33 descends is greater than the speed at which the top 33 ascends. Furthermore, the distance in the outgoing direction is greater than the distance in the incoming direction. Therefore, the speed at which the top 33 exits the rotating frame 13 is greater than the speed at which the top 33 enters the rotating frame 13.

[0048] The detection unit 52 of the operation panel 5 detects the number of contact points of the initial contact and the number of contact points of the subsequent contact. The signal generation unit 55 then generates a control signal related to the movement speed of the tabletop 33 based on the numbers of both contact points. For example, the signal generation unit 55 may generate a control signal that increases the movement speed of the tabletop 33 as the number of contact points increases. As shown in FIG. 5(b), when comparing the total number of contact points of the initial contact and the total number of contact points of the subsequent contact, the number of contact points in the downward direction is greater than the number of contact points in the upward direction. For example, the index finger and middle finger are used for the subsequent contact in the downward direction. Therefore, the speed at which the tabletop 33 descends is greater than the speed at which the tabletop 33 ascends. Furthermore, the number of contact points in the outgoing direction is greater than the number of contact points in the incoming direction. For example, the index finger and middle finger are used for the subsequent contact in the outgoing direction. Therefore, the speed at which the top plate 33 exits the rotating frame 13 is greater than the speed at which the top plate 33 enters the rotating frame 13 .

[0049] The signal generating unit 55 may generate a control signal related to the movement speed of the tabletop 33 based on other numerical values ​​instead of the total number of contact points. For example, the signal generating unit 55 may generate a control signal related to the movement speed of the tabletop 33 based on the difference or ratio between the number of contact points of the first contact and the number of contact points of the next contact.

[0050] As a variation of the above, the detection unit 52 of the operation panel 5 may detect the pressure of a finger pressing down on the surface of the detection unit 52 at the next contact. At this time, the detection unit 52 acquires the pressure detected by, for example, a pressure sensor installed on the back side of the surface. The signal generation unit 55 generates a control signal related to the movement speed of the tabletop 33 based on the pressure of the contact. The signal generation unit 55 may generate a control signal such that the movement speed of the tabletop 33 increases as the contact pressure increases.

[0051] Furthermore, the detection unit 52 of the operation panel 5 detects, as a touch by the user, an operation in which the user's finger touches the detection unit 52 and then flicks in a predetermined direction (flick operation). The control device 15 controls the top board 33 to move in a direction corresponding to the predetermined direction at a speed slower than a predetermined speed. As shown in FIG. 5(c), the user first touches the position of the black circle on the detection unit 52 with their thumb and then flicks the thumb upward. When the detection unit 52 detects the upward flick operation on the operation panel 5, the signal generation unit 55 generates a control signal including an instruction to move the top board 33 upward in the y-axis direction at a slower speed. The first communication unit 56 transmits a control signal including an instruction to move the top board 33 upward in the y-axis direction at a speed slower than the predetermined speed to the control device 15 via the bed device 30. The flick operation on the operation panel 5 corresponds to the slow movement of the top board 33.

[0052] The movement speed of the tabletop 33 may be switchable between two levels, three levels, or four or more levels. The three levels may be, for example, "normal," "slower than normal," and "faster than normal." Furthermore, the movement speed of the tabletop 33 may be continuously changeable. In this case, the movement speed may be set according to the distance between the contact points or the speed of the operation by the fingers.

[0053] Conventional operation panels have one fast button and four slow buttons for slow operation in each direction. When the user presses one of the four slow buttons without pressing the fast button, the slow operation is performed. The flick operation according to this embodiment applies the conventional slow operation with one action.

[0054] According to the second embodiment, the movement speed of the tabletop 33 can be switched depending on the distance between the first contact point and the next contact point, the number of fingers in contact, the pressure of the contact, whether there was one contact or two contacts, etc. Regarding the distance between the contact points, the movement speed of the tabletop 33 increases as the distance increases. Note that as the distance between the contact points, i.e., the distance between the fingers in the detection unit 52, gradually increases from a short state, the movement speed of the tabletop 33 increases accordingly, allowing for natural operation. Also, safety can be ensured by allocating flick operations to slow or super slow operations of the tabletop 33.

[0055] Third Embodiment Fig. 6 is a perspective view showing the appearance of operation panel 5a according to the third embodiment. As shown in Fig. 6, detection unit 52 is a touch panel having protrusion 53 provided in the approximate center. This allows the user to make an initial contact by searching for protrusion 53 with the thumb, and thus protrusion 53 can be used as the reference position. Furthermore, because the position of the initial contact is approximately the center of detection unit 52, the position of the next contact is secured in any area above, below, left, or right from the position of the initial contact on detection unit 52, allowing the user to reliably operate operation panel 5a.

[0056] 6, the bezel 54, which is the frame of the operation panel 5a, is formed higher than the surface of the detection unit 52. This allows the boundary between the surface of the detection unit 52 and other parts to be recognized by touch. Therefore, when operating the operation panel 5a without looking at it, the user can determine whether or not their fingers are touching the surface of the detection unit 52. Note that the operation panel 5a may include at least one of the protrusions 53 and the bezel 54.

[0057] FIG. 7 is a perspective view showing the appearance of an operation panel 5b according to the third embodiment. As shown in FIG. 7, the display unit 51 displays a different display than usual. For example, the detection unit 52 is a touch panel that displays a message that the user is currently operating the operation panel without looking at it. This allows the user to operate the operation panel 5b without looking at it, but informs surrounding staff that the user is operating the operation panel 5b without looking at it. Therefore, surrounding staff can be aware of ensuring safety while paying attention to the movement of the top panel 33, etc.

[0058] The detection unit 52 does not necessarily have to be a touch panel that also includes the display unit 51, but may be something like a touchpad provided in front of the keyboard of a notebook PC. In other words, the detection unit 52 may have only the function of detecting contact with a human finger.

[0059] Furthermore, the area on the surface of the detection unit 52 where contact with a finger can be detected may be limited, thereby preventing erroneous operations and reducing unnecessary areas.

[0060] As a modified example of the operation according to the third embodiment, for example, the control device 15 may perform control so that the movement of the tabletop 33 starts several seconds after the completion of the user operation shown in Fig. 4 or 5. Furthermore, after the user operation shown in Fig. 4 or 5 is completed, the user may further flick his or her finger to permit or stop the actual movement of the tabletop 33.

[0061] Furthermore, the detection unit 52 of the operation panel 5 identifies the area of ​​the surface that is in contact with the user's fingers. Then, the control device 15 may perform control so as to stop the movement of the tabletop 33 when the contact area is equal to or greater than a predetermined area. As an emergency stop operation, the user may, for example, touch the detection unit 52 of the operation panel 5 with the entire palm of their hand. In this case, the detection of contact of equal to or greater than the predetermined area triggers the movement of the tabletop 33 to stop.

[0062] According to the above-described modified operation, operational safety can be ensured.

[0063] [Fourth embodiment] In the first to third embodiments, the operations of vertical movement and parallel translation of the top board 33 have been described, but operations may also be performed to move other parts of the top board 33, or operations may be performed to move something other than the top board 33.

[0064] When placing the subject P on the top 33, the user may wish to tilt or rotate the top 33. Therefore, the user may use the operation panel 5 to tilt or rotate the top 33. When rotating the top 33, the user may, for example, first touch the detection unit 52 of the operation panel 5 with their thumb, then with their index finger, and then slide the index finger clockwise or counterclockwise around their thumb to indicate the direction of rotation of the top 33. At this time, the detection unit 52 detects that the two contact points maintain a constant distance between them, with the first contact point remaining stationary and the second contact point sliding in an arc. In this case, the control device 15 controls the top 33 to rotate in a direction corresponding to the movement of the second contact point.

[0065] The operation panel 5 may be used not only to move the tabletop 33 but also to move the gantry 10. The gantry 10 is an example of a movable part and a gantry. The gantry 10 can be tilted. For example, referring to FIG. 2, tilting can be performed in two directions: tilting the upper part of the front (right side) or back (left side) of the gantry 10 from a vertical position toward the back (left side), or tilting toward the bed 30 (right side). There are also different tilt angles for the gantry 10. The control device 15 may also control the on / off of the X-ray tube 11 provided in the gantry 10 based on the user's contact with the detection unit 52.

[0066] According to at least one of the embodiments described above, when moving the medical image diagnostic apparatus, it is possible to operate it as intended without looking at the operation part.

[0067] In the above embodiments, the term "processor" refers to a circuit such as a dedicated or general-purpose CPU (Central Processing Unit), GPU (Graphics Processing Unit), or an Application Specific Integrated Circuit (ASIC), a programmable logic device (e.g., a Simple Programmable Logic Device (SPLD), a Complex Programmable Logic Device (CPLD), or a Field Programmable Gate Array (FPGA)). If the processor is a CPU, for example, the processor realizes various functions by reading and executing programs stored in a memory circuit. Also, if the processor is an ASIC, for example, instead of storing programs in a memory circuit, functions corresponding to the programs are directly built into the processor circuit as logic circuits. In this case, the processor realizes various functions by hardware processing that reads and executes the programs built into the circuit. Alternatively, the processor can realize various functions by combining software processing and hardware processing.

[0068] In addition, although the above embodiment shows an example in which a single processor of a processing circuit realizes each function, a processing circuit may be configured by combining multiple independent processors, and each processor may realize each function. Furthermore, when multiple processors are provided, a memory circuit for storing programs may be provided separately for each processor, or a single memory circuit may collectively store programs corresponding to the functions of all processors.

[0069] Although several embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included within the scope and spirit of the invention, as well as within the scope of the invention described in the claims and their equivalents.
