CT equipment, as a kind of armarium gathering medical image, generally includes scan table and control station.Wherein, scan table can comprise gantry and scanning bed; Gantry is the important component part of CT equipment, it is provided with usually x-ray generator, high pressure bulb, detector, collimator, hardware system (can comprise processor and memorizer) etc.; Scanning bed is the instrument coordinating gantry to complete scan task, for delivery by scanning person.Control station can comprise function panel, this function panel is provided with various for gantry or the scanning bed functional keys carrying out moving, when certain functional keys is operated, hardware system on gantry can receive corresponding control instruction, and perform banking motion according to this control instruction, or gated sweep bed performs entering bed, moving back bed motion of aperture on automatic turnover gantry, or rise bed, fall bed motion etc.
The position of functional keys set on usual function panel is fixed, namely the controlling party of functional keys is to adaptive with the conventional placement direction of scan table, such as, the conventional placement direction of scan table is for place left, namely gantry is in scanning bed left side, then correspond on function panel, enter a button to be arranged on and to move back on the left of a button, during to ensure that pressing left side enters a bed button, the scanning bed aperture being moved into gantry left, performs into bed motion, and presses right side when moving back a bed button, scanning bed moving right is exited from the aperture of gantry, performs and moves back bed motion.From the above, the setting of functional keys and the conventional placement direction adaptation of scan table, mainly refer to that this set meets the routine operation custom of operator and general visual movement perception.But, if the placement direction of scan table changes, cause the controlling party of functional keys to cannot be adaptive with the placement direction of scan table, such as, scan table is changed to by aforementioned placement left and places to the right, then now operate into a button, scanning bed to be moved in the aperture away from gantry, a button is moved back in like manner operation, scanning bedly to be moved in the aperture to gantry, thus causes accurately to be controlled by the motion of operation control panel to scan table.
Therefore in the embodiment of the present invention, by when determining the placement direction between scan table and function panel and changing, the direction of motion of adjustment indicated by control instruction, to make the motion of scan table consistent with the placement direction after change, thus when ensureing that the setting position of the functional keys on function panel is constant, motor control is accurately carried out to scan table, promotes the overall work degree of accuracy of CT equipment.Describe the present invention below in conjunction with specific embodiment.
See Fig. 1, an embodiment flow chart for the method for gated sweep platform motion of the present invention:
Step 101: the placement direction information obtaining scan table.
In this step, following either type can be adopted to obtain the placement direction information of scan table.
The first: preserve the placement direction information of scan table by software design patterns.Usual control station can also comprise display device, this display device can present the software control interface of control station, after scan table has been placed, the placement direction information of scan table can be inputted in software control interface, and by this placement direction information transmission to gantry, by gantry, this placement direction information is preserved.
The second: the placement direction information being detected scan table by induction installation.When placement direction due to scan table changes, gantry and scanning bed usual interlock, therefore can in advance gantry or scanning bed on induction installation is set, such as, gyro sensor, can detect the placement direction information of scan table by this induction installation.
Step 102: according to placement direction information, judges whether scan table changes relative to the placement direction of function panel.
In a possible implementation, can in advance for function panel arrange induction installation, in order to the placement direction information of measuring ability panel.When after the placement direction information being got function panel by induction installation, according to the angular separation between the placement direction information determination scan table of the placement direction information of scan table and function panel and function panel, and can judge whether scan table changes relative to the placement direction of function panel by this angular separation.
When adopting angular separation to judge whether placement direction changes, can in advance by the placement direction of scan table with the controlling party of function panel to direction time consistent, be defined as the inceptive direction of scan table, and based on this inceptive direction, the angular range judging placement direction situation of change is set.Based on above-mentioned setting, after determining angular separation, the angular range belonging to this angular separation can be judged, when angular separation belongs to the first angular range, determine that scan table is constant relative to the placement direction of function panel, when angular separation does not belong to the first angular range, determine that scan table changes relative to the placement direction of function panel.Such as, suppose that inceptive direction is that scan table is placed relative to function panel left, the lower limit of the first angular range is greater than 0 degree, and higher limit is less than or equal to 90 degree, namely the first angular range is (0,90], then when angular separation α belong to (0,90] time, can determine that scan table is still placed relative to function panel left, when angular separation α (-90,0] between time, then can determine that scan table is changed to relative to function panel places from placing left to the right.
Step 103: if change, then when receiving the control instruction that function panel sends, the direction of motion that control instruction indicates is adjusted to change after placement direction adaptive.
Because the actual kind of CT equipment is different with specification, the functional keys that its function panel is arranged also is not quite similar.As a rule, functional keys can comprise one or more groups button following: just inclining button and the negative button that inclines, and enters a button and move back a button, rise bed button and fall a button etc.Corresponding to the functional keys of above-mentioned example, the control instruction that function panel sends can comprise: by operation just inclining button control gantry just inclining motion instruction of just inclining; The negative instruction of inclining of motion of inclining is born by operating the negative button control gantry that inclines; By operate into a button control scanning bed enter bed motion enter an instruction; By operation move back a button control scanning bed move back bed motion move back an instruction; By operation rise bed button control scanning bed rise bed motion rise bed instruction; By operation fall a button control scanning bed bed motion falls and an instruction is fallen.
In a possible implementation, change at the placement direction of scan table relative to function panel, and when receiving the control instruction that function panel sends, can for the placement direction of the scan table after change, the direction of motion of self-adaptative adjustment control instruction instruction, with ensure scan table motion can with its change after placement direction adaptive.Example in integrating step 102, when scan table relative to function panel from after placing left and being changed to and placing to the right, then when receiving into bed instruction, the direction of motion can be adjusted to move back bed from entering bed, in like manner, receive move back a bed instruction time, the direction of motion can be adjusted to into bed from moving back bed.
Step 104: move according to the direction of motion after adjustment.
