An embodiment of the present invention provides a kind of data correcting method, the executive agent of this method can be FPGA or any Control terminal including FPGA.In embodiments of the present invention, it is illustrated by taking executive agent in order to control terminal as an example.Referring to Fig. 2, This method includes:
Step 201:During continuous moving scans target object, control terminal determines target response to be corrected Line.
In embodiments of the present invention, during detector continuous moving scanning target object, control terminal is in real time to visiting The line of response that device detects is surveyed to be corrected.Therefore, detector often detects a line of response, and control terminal is obtained from detector Take a target response line to be corrected.Wherein, detector includes line of response processing module.The line of response processing module is used for Generate line of response.Correspondingly, control terminal obtains target response line to be corrected from the line of response processing module in detector. The target response line can be any line of response that detector detects.Detector can be pet detector.
Step 202:Control terminal parses the crystal detection pair for detecting the target response line from the target response line The detection time of location information and the target response line in probe unit.
The crystal detection for detecting target response line is had recorded in the target response line to the position letter in probe unit The detection time of breath and target response line.In this step, it is brilliant directly to parse detection from the target response line for control terminal The detection time of the location information of body pair and the target response line.
For example, the location information that control terminal gets crystal detection pair is respectively det1 and det2, which is t。
Step 203:Control terminal determines the target response according to the location information of the crystal detection pair and the detection time The weight of line.
In a possible realization method, this step can be realized by following steps (1) to (3), including:
(1):Control terminal determines the crystal detection to corresponding two according to the location information of the crystal detection pair The normalization factor and two coincidence correction factors.
Crystal detection is to including two crystal detections, and a crystal detection corresponds to a normalization factor and one dead The time adjustment factor.In a possible realization method, in order to realize doubling correction data, to improve correction efficiency.Control Terminal processed includes three independent controllers, and three independent RAM are arranged, these three independent RAM, which can be arranged, to be controlled Terminal inner processed can also be arranged outside control terminal.Control terminal is realized by three independent controllers respectively respectively Normalization, coincidence correction and decay correction.Correspondingly, this step can be real by following steps (1-1) and (1-2) It is existing, including:
(1-1):Control terminal is by the first controller, according to the location information of the crystal detection pair, from first it is static with Corresponding two normalizings of location information of the crystal detection pair are obtained in the normalization factor table of machine access memory storage Change correction factor.
There is a large amount of crystal detection in detector, since crystal detection is influenced by itself geometric position and performance difference, So that the detection efficient of the crystal detection in detector is inconsistent.Therefore, the location information corresponding two of crystal detection pair is obtained A normalization factor subsequently combines the two normalization factors, is corrected to the target response line, to visit The line of response measured is mapped exactly in dummy detector.Wherein, normalization factor table, the normalizing are stored in the first RAM Change the correspondence of storage detection crystal and the normalization factor in correction factor table.
Before this step, control terminal needs to generate normalization factor table.Control terminal generates normalization The process of factor table can be:
Control terminal controls detector and detects reference light source, obtains the counting rate of each crystal detection in the detector; According to the counting rate of the reference count rate and each crystal detection of each crystal detection, the normalization school of each crystal detection is determined Positive divisor.Control terminal by the location information of each crystal detection and normalization factor associated storage normalization because In sublist.Wherein, reference light source is equally distributed radioactive source or rotation sweep line source etc..
For each crystal detection, control terminal is according to the counting rate of the crystal detection and the reference count of the crystal detection The step of rate, the normalization factor for determining the crystal detection can be:Control terminal is by the reference count of the crystal detection The ratio of rate and the counting rate of the crystal detection is determined as the normalization factor of the crystal detection.
(1-2):Control terminal is determined according to the location information of the crystal detection pair comprising detection by second controller The location information of the probe unit pair of crystal pair, according to the location information of probe unit pair, from the second static random access memory The corresponding two coincidence correction factors of location information of probe unit pair are obtained in the coincidence correction factor table of device storage, extremely The correspondence of the location information of storage detection unit and the coincidence correction factor in the time adjustment factor.
Detector includes multiple probe units, and each probe unit includes multiple crystal detections.It is deposited in control terminal Store up location information of each probe unit in detector, and each location information of the crystal detection in probe unit.Phase It answers, control terminal determines the spy for including crystal detection pair by second controller according to the location information of the crystal detection pair Survey unit pair location information the step of can be:Control terminal is by second controller, according to the position of the crystal detection pair Information, it includes the crystal detection pair to be obtained from the correspondence of the location information of the location information and probe unit of crystal detection Probe unit pair location information.
Since process performance of electronics itself causes the also untreated complete the latter annihilation event of current annihilation event to send out again It is raw, cause the latter's annihilation event to lose.Therefore, coincidence correction subsequently is being carried out to the line of response detected to crystal detection, To which the line of response detected is mapped exactly in dummy detector.Before this step, when control terminal needs to generate dead Between correction factor table.The correspondence of the location information and the coincidence correction factor of storage detection unit in the coincidence correction factor table Relationship.Wherein, the process of control terminal generation coincidence correction factor table can be:
Control terminal controls detector and detects radioactive source, and the counting rate for obtaining each probe unit in the detector is bent Line determines the coincidence correction factor of each probe unit according to the count rate curve of each probe unit.Control terminal will be every The location information and coincidence correction factor associated storage of a probe unit are in coincidence correction factor table.
When putting a strong radioactive source, with its strength reduction of time, it can be seen that counting rate is gradually curved, when intensity drops After to a certain degree, counting rate linearly declines, and according to the count rate curve of each probe unit, can calculate each detection Unit with Strength Changes the coincidence correction factor.Wherein, radioactive source can be that radioactive tracer or detector itself have There is the crystal of decay function.Radioactive tracer can be18F-FDG(2-Fluorine-18-Fluoro-2-deeoxy-D- Glucose, 2- Value linear-fluoro- 2-deoxy-D-glucose) solution.Itself have decay function crystal can be containing176LU's LYSO crystal.
It should be noted that the first controller and second controller are different controllers, and the first static random-access Memory and the second static RAM are different memories.Also, step (1-1) and step (1-2) are not Sequencing executes parallel.Due to using independent first static RAM and the second static state in the present invention Random access memory stores normalization factor table and coincidence correction factor table respectively, passes through the first controller and second Controller realizes the flowing water inquiry normalization factor and the coincidence correction factor, to improve treatment effeciency.
(2):Control terminal determines the decay correction factor of the target response line according to the detection time.
Control terminal is stored according to the detection time from third static RAM by third controller The corresponding decay correction factor of the detection time is obtained in decay correction factor table, in the decay correction factor table when storage detection Between and the decay correction factor correspondence.
Before detecting target object by detector, radioactive tracer is injected in target object.Due to the radiation Property tracer nucleic have a half-life period, intensity is reduced with time index rule, the number of the line of response of a certain position As the time is reduced.Therefore, decay correction subsequently is being carried out to line of response, to which same position to be generated to the counting rate of line of response Normalize to some moment (injection time).Before this step, control terminal needs to generate decay correction factor table.This declines Become the correspondence of storage detection time and decay factor in correction factor table.Wherein, control terminal generates the decay correction factor The process of table can be:
Control terminal detect benchmark radioactive tracer, obtain probe unit detect line of response multiple detection times and Intensity;The reference intensity for obtaining each detection time determines decay correction according to the intensity and reference intensity of each detection time The factor.Control terminal is by each detection time and decay correction factor associated storage in decay correction factor table.
(3):Control terminal according to two normalization factors, two coincidence correction factors and the decay correction because Son determines the weight of the target response line.
Control terminal is by two normalization factors, the product of two the coincidence correction factors and the decay correction factor Weight as the target response line.
For example, two normalization factors are respectively norm (det1) and norm (det2), two coincidence corrections because Son is respectively dt (det1') and dt (det2'), which isT12For the half-life period of nucleic.The then target The weight of line of response is
Step 204:Control terminal obtains the displacement distance of the target object.
For example, the displacement distance that control terminal obtains the target object is d.
Step 205:Control terminal determines according to the location information of the displacement distance and the crystal detection item and rings the target Answer two virtual responsive lines that line is mapped in dummy detector.
This step can be realized by following steps (1) to (2), including:
(1):Control terminal determines the number of crystals of target object movement according to the width of the displacement distance and crystal detection Mesh.
Control terminal determines the ratio between the displacement distance and the width of the crystal detection, and the upper rounding of the ratio is made For the crystal number of target object movement.
For example, displacement distance is (d), the width of crystal detection is (l), then is equivalent to the crystal number of target object movement For i, thenWherein i is integer.
(2):Control terminal is determined according to the location information of the crystal detection pair and the crystal number in dummy detector The location information of the corresponding two virtual responsive lines of the target response line.
Control terminal determines the crystal detection to the position in dummy detector according to the location information of the crystal detection pair Confidence ceases, and according to the crystal detection to location information and the crystal number in dummy detector, determines two virtual responsives The location information of line.
For example, the location information of the crystal detection pair is (det1, det2), which is i, then two virtual responsives The location information of line is respectively (det1+i, det2+i) and (det1+i+1, det2+i+1).
Step 206:Control terminal determines the weight of two virtual responsive lines according to the weight of the target response line.
This step can be realized by following steps (1) to (3), including:
(1):Control terminal obtains the location information for the virtual crystal that the target response line is mapped in dummy detector.
(2):Control terminal is mapped to dummy detector according to the location information and the target response line of the virtual crystal pair In two virtual responsive lines location information, determine target response line in dummy detector between two virtual responsive lines Relative distance.
For example, the location information of two virtual responsive lines is respectively (det1+i, det2+i) and (det1+i+1, det2+i+ 1), then the relative distance between the virtual crystal and two virtual responsive lines is to be respectivelyWith
(3):Control terminal according to the weight of the target response line, the target response line in dummy detector with two void Relative distance between quasi- line of response, determines the weight of two virtual responsive lines.
Control terminal determines relative distance of the target response line in dummy detector between two virtual responsive lines With the ratio of the width of virtual crystal, two ratios are obtained, the weight of the target response line and the product of two ratios are obtained The weight of two virtual responsive lines.
For example, with reference to Fig. 3, relative distance of the target response line in dummy detector between two virtual responsive lines RespectivelyWithThe width of the virtual crystal is l, then two ratios are respectively: WithThe weight of the target response line isThen The weight of two virtual responsive lines is respectively: With
Step 207:Control terminal, will according to the location information of the weight and two virtual responsive lines of two virtual responsive lines Two virtual responsive lines are mapped in dummy detector.
