Tomographic apparatus can obtain figure according to various scan patterns or scan method according to an embodiment of the invention As data.Example for the scan pattern of tomoscan can include perspective (prospective) pattern and retrospective (retrospective) pattern, this will be described in detail with reference to Fig. 2 and Fig. 3 below.Scanning side for tomoscan The example of method includes axial scanning method and spiral scanning method, is described in detail this now with reference to Fig. 2 and Fig. 3. The CT system 100 of Figure 1A and Figure 1B can perform to break according to the scan method described now with reference to Fig. 3 and Fig. 4 and scan pattern Layer scanning.

The diagram of the scan method used when Fig. 3 is according to an embodiment of the invention for explaining tomoscan.

Fig. 3 is the diagram for describing the tomoscan according to spiral scanning method.Additionally, Fig. 3 is for describing basis The diagram of the tomoscan of retrospective pattern.

Scan pattern can be the most constant and determine according to the heart rate of the patient that will carry out imaging.Electrocardiogram (ECG) gates Can be used for obtaining for the initial data rebuilding image.In figs. 3 and 4, when performing tomoscan, the workbench of Figure 1B 105 move along the axial direction of patient 305.

With reference to Fig. 3, spiral scanning method is such tomography method: at the workbench 105 of Figure 1B in from t=0 to t In the predetermined amount of time of=end while motion, projection X-ray is to be scanned continuously.In detail, by making Figure 1B's Workbench 105 (including that the patient 305 of object is positioned on workbench) moves the most continuously, and And project X-ray continuously to perform tomoscan to object while workbench 105 moves.Therefore, the motion rail of X-ray Mark 350 can be spiral form.

With reference to Fig. 3, as the heart rate of patient irregular (as ARR patient), the regular decline of heart rate, Therefore the cycle cannot be detected as under perspective pattern at regular intervals.In this case, ECG signal 360 exists Gated at random under retrospective pattern.Under retrospective pattern, by within whole cycles of ECG signal or ECG signal Continuous print predetermined period in radiation X ray obtain initial data, then select for tomoscan image rebuild part Cycle.

Under retrospective pattern, it is separately arranged to the partial periodicity of image reconstruction to detect partial periodicity user 361, after 362 and 363, user is by the sheet of the initial data of acquisition in the partial periodicity 861,862 and 863 detected respectively Section is used in the reconstruction of tomoscan image.In other words, image processor 220 can by use data 380 include in portion The initial data 381 that obtains in 361 at times, partial period 362 in acquisition initial data 382 and at partial period The initial data 383 obtained in 363 rebuilds tomoscan image.Such as, image processor 220 can be by using when part The initial datas 381 obtained in section 361 are rebuild the tomography of the predetermined point of time representing that object includes at partial period 361 and are swept Tracing picture, and expression object can be rebuild at partial period by using acquisition initial data 382 in partial period 362 The tomoscan image of 362 predetermined point of time included.

Such as, under retrospective pattern, in the special time period of t=0 to t=end, project X-ray continuously, from And perform tomoscan.Owing to the workbench 105 of Figure 1B moves the most continuously, therefore X penetrates The movement locus 350 of line is spiral form.

Another scan method used when Fig. 4 A and Fig. 4 B is according to an embodiment of the invention for explaining tomoscan Diagram.

With reference to Fig. 4 A, axial scanning method is such tomography method: it is same that the workbench 105 at Figure 1B stops Time, projection X-ray to be scanned, workbench 105 moved from 401 to 802 predetermined space, then for predetermined segment 422 projection X-ray, thus obtain initial data.Tomographic apparatus 200 can obtain view data according to axial scanning method.

With reference to Fig. 4 A, for having the people of constant heart rate, by using perspective pattern that ECG signal 410 is advised Rule ground gate.Under perspective pattern, automatically selecting or extract predetermined segment 421, predetermined segment 421 is positioned at and R peak point The 411 time point t3 separating predetermined amount of time.During the predetermined segment 421 being gated, it is former to obtain that X-ray is applied to object Beginning data.Under perspective pattern, automatically selecting predetermined segment 422, section 422 is positioned at and separates pre-timing with R peak point 412 Between the time point t4 of section.Now, while the workbench 105 of Figure 1B stops, X-ray, to be scanned, workbench are projected 105 moved from 401 to 402 predetermined space, then project X-ray for predetermined segment 422, thus obtain initial data.

With reference to Fig. 4 B, the view data 460 obtained in the section (such as, predetermined segment 421 or 422) selected or extract Length direction corresponding with the time.In other words, view data 460 can be from time point t41 to the time of time point t42 The data that section obtains.It is often necessary to the fragment of the data more than the view data needed for the reconstruction of tomoscan image.Such as, when When the amount of the view data needed for the reconstruction of tomoscan image is the first data volume 461, fill period (padding first Period) 471 also can obtain data, also can obtain data in the second filling period 475.

When tomoscan, for having the patient of erratic heart rate, can by by retrospective model application to spiral Scan method performs tomoscan.For having the patient of regular heart rate, can by by perspective model application to axial Scan method performs tomoscan.But, embodiments of the invention are not limited to this, can by by perspective model application to spiral shell Revolve scan method or by retrospective model application is performed tomoscan to axial scanning method.Fig. 5 shows ECG signal 510。

Heart is by shrinking to health blood supply periodically.The heart beating period of heart can be based on the signal of telecommunication produced by heart Determine.Such as, the sinuatrial node in heart the signal of telecommunication produced can check (the electrode by attaching to skin surface via ECG Detect the signal of telecommunication coming from heart) and determine.The signal of telecommunication (that is, ECG signal) detected is represented by curve chart.ECG Signal includes the cycle information of heart beating period.By analyzing ECG signal, user can determine that the interval when motion of heart is minimum, And also can determine that the rhythm of the heart is irregular, fast or slow.

Therefore, during CT scan, image processor 220 can use ECG signal to move to reduce in tomoscan image The generation of artifact.Such as, by using ECG signal, when tomographic apparatus 200 can obtain part when moving minimum of heart Section, and tomoscan image can be rebuild by using the view data obtained in the partial period obtained.As above institute Select a part and from selected period part (hereinafter, referred to as partial period) period from ECG signal stated The operation obtaining view data is referred to as ECG gate.

Such as, image processor 220 carries out windowing by ECG gate to the predefined phase section of ECG signal 510, thus Obtain some periods P1 and P2.Image processor 220 can control some periods of ECG signal, to add it Window also shows.

With reference to Fig. 5, ECG signal 510 includes multiple singular point in each cycle 520.Such as, the cycle 520 includes R peak Value point 511, Q peak point 512 and S peak point 513.Within the heart beating period, produce R peak point time time point t1 with produce next The interval between time point t2 during individual R peak point can be referred to as the cycle 520.

The operator scheme of ECG gate can be the most constant and change based on cardiac cycle.Such as, constant when the cardiac cycle of people Time, under perspective pattern, ECG signal 510 is gated.Under perspective pattern, image processor 220 automatically selects predetermined rank Section section P1, P1 are positioned at and separate the time point t3 of predetermined amount of time t4 with R peak point 511.In other words, in perspective pattern Under, after each cycle detects R peak point 511, it is positioned at for the detection of each time point and divides with the R peak point detected Open the predetermined segment of the time point of predetermined amount of time, when rebuilding tomoscan image, use only in the predetermined segment detected The fragment of the view data of middle acquisition.

As another example, when when cardiac cycle ARR patient is non-constant, the regularity of cardiac cycle Reducing, therefore as under perspective pattern, uniform period detection is infeasible.At retrospective pattern hypograph processor 220 pairs of ECG signal 510 gate.Under retrospective pattern, by all cycles of ECG signal 510 or particular range In cycle, radiation X ray obtains view data continuously, partly selects the partial period for image reconstruction.In other words Say, under retrospective pattern, user setup by during at image reconstruction use partial period then test section P1 at times and After P2, the view data obtained in partial period P1 and P2 detected is used in the reconstruction of tomoscan image by user.
