The specific embodiment
Fig. 2 is the embodiment sketch map of the operating control device of computer dislocation scanning and imaging system of the present invention; according to the present invention; the operating control device of this computer dislocation scanning and imaging system has a control box 10; be provided for control knob 101-108 that sick bed and bright dipping are operated on this control box; wherein 101 is that window width is adjusted knob; the 102nd, knob is adjusted in the window position; these two knobs are to be used to be provided with CT image observation parameter; the 103rd, the emergency shutdown button; shut down when being used to emergency takes place; the 104th, pause button, the 105th, go out light button, the 106th, open speaker button; the operator presses this button and can converse with patient; the 107th, drive the microphone button, the operator presses this button can call out patient, and the 108th, move a button.
On the control box 10 except above-mentioned control knob is set, also be provided with the control knob 201-205 of relevant scanning process.These control knobs relevant with scanning process comprise: be used to load loading button 201, the reconstruction button 202 that is used to begin reconstructed image, the cancellation movable button 203 that is used to cancel mobile sick bed action, the cancel button 204 that is used to cancel current operation of locating picture or tomoscan project, the termination reconstruction button 205 that is used to end reconstructed image.
In normal scanning imaging system, the operator at first is the suitable sweeping scheme of patient selection, and the loading button of pressing then among Fig. 2 201 loads sweeping scheme.After having selected sweeping scheme, the operator selects the location to locate as sweep parameter as option and input on user interface, and the loading button of pressing then among Fig. 2 201 loads the location as sweep parameter.
The operator has loaded the location as after the sweep parameter, and the light button of pressing among Fig. 2 105 that goes out positions picture scanning.If in locating as scanning process, patient has moved the position, perhaps sweep limits has reached requirement (promptly can see focus), presses the cancel button 204 among Fig. 2 this moment, and the cancellation bright dipping makes patient need not to accept unnecessary x-ray bombardment.
Can obtain a sweep limits after the location is as the end of scan, this sweep limits does not match with current berth usually, and the 108 pairs of sick beds of a button that move that need press among Fig. 2 this moment move, and itself and sweep limits are complementary.If sweep limits that by chance obtains and current berth coupling are then pressed the cancellation movable button 203 among Fig. 2, do not need sick bed to move.
The location as the end of scan after, show the location picture in the picture district, location of computer screen, the operator further determines scan plan, promptly delimits scanning area with square frame.Simultaneity factor enters the tomoscan programs option automatically, during the sweep parameter that the operator shows in the parameter setting area is provided with sweep parameter is set, for example effective current (milliampere-second, mAs), sweep time, bed thickness, dosage etc. parameter.Then, during the reconstruction parameter that the operator shows is provided with reconstruction parameter is set in the above-mentioned parameter setting area, for example tomography, rebuild increment, convolution kernel, window value etc., the loading button of pressing then among Fig. 2 201 loads the tomoscan parameter, and the light button of then pressing among Fig. 2 105 that goes out carries out tomoscan.
In the tomoscan process, suppose that bright dipping proceeds to half and just scanned focus, at this moment the operator can press the current action button 104 of termination among Fig. 2, and for confirmation whether the needs continues to scan or termination scanning.If the operator thinks to be necessary to continue to scan so that find the wider focus or the focus of transfer that through confirming the light button of then pressing once more among Fig. 2 105 that goes out is proceeded tomoscan.If the operator thinks that scanning has reached requirement, press the cancel button 204 among Fig. 2 this moment, the cancellation bright dipping makes patient need not to accept unnecessary x-ray bombardment.
Usually the CT chance is carried out image reconstruction automatically according to the reconstruction parameter that is provided with after the tomoscan.After image reconstruction, if the operator wants to rebuild other one group of image,, then need to add in addition reconstruction tasks, definition reconstruction parameter so that obtain further image effect, press the reconstruction button 202 of beginning reconstructed image among Fig. 2 then, carry out image reconstruction.In this image reconstruction process carries out, if the operator thinks that the reconstructed image that obtains has at present satisfied its requirement, need not to continue following image reconstruction, then press the termination that being used among Fig. 2 end reconstructed image and rebuild button 205.
For the ease of distinguishing the button of normal action button of controlling of expression and expression hang up or cancellation operation, the control knob 201-205 that is used for scanning process among Fig. 2 can be designated different colours.For example, the loading button 201 of location picture or tomoscan project, the reconstruction button 202 that is used to begin reconstructed image are designated blueness, expression is ended or the button 203,204,205 of cancellation operation is designated redness with being used among the control knob 201-205 to load.
Button among Fig. 2 is generally made by transparent plastics, the built-in luminous tube of button.When the represented operation of button was allowed to, luminous tube was lighted, and when the represented operation of button was under an embargo, luminous tube extinguished.The operator just can know the current operation that can carry out intuitively by the light on and off of button.
Correspondingly, the present invention proposes a kind of method of controlling operation thereof of computer dislocation scanning and imaging system, use being used on the control box 10 that the control knob 101-108 that sick bed and bright dipping are operated is operated sick bed and bright dipping, and use the control knob 201-205 that is used for scanning process on the described control box that scanning process is operated.
Use the control knob that is used for scanning process on the control box 10 to comprise that use one loading button 201 loads location picture or tomoscan project, use one reconstruction button 202 beginning reconstructed images, uses a cancellation movable button 203 to cancel the action of mobile sick bed, the current operation of use one cancel button, 204 cancellations, use an at least a using method of ending reconstruction button 205 termination reconstructed images to operate.
The control box button layout in the present embodiment and the number of button and function be not subjected to show among Fig. 2 limit, when reality realizes, may do corresponding change with the difference of CT type and software.
