In specific assessment models, intelligence is established in processing based on the calculated result of computer system parameter can be used
It can evaluation module.Doctor can judge disease state with reference to assessment result, improve diagnosis efficiency, reduce misdiagnosis rate.
In some embodiments, specific assessment models mainly consist of two parts, concentrated area degree of correlation D (r) and dense
It spends degree of correlation D (t).
Specific evaluation process is as follows:
S20 pre-processes the characteristic;The preprocessing process be by or the characteristic processing be
Computer it will be appreciated that computer binary language.
S30 analyzes the pretreated data, obtains analysis result;
Determine that the concentrated area of cancer cell has great significance for cancer assessment.For non-small cell lung cancer
(NSCLC), determine that concentrated area degree of correlation D (r) and concentration degree of correlation D (t) help that doctor is made to select suitable treatment method.
For non-diffused NSCLC, Direct Surgery excision is main treatment method, for the NSCLC spread, operation
It is main treatment method with drug therapy.The analysis of concentrated area degree of correlation D (r) and concentration degree of correlation D (t) are specific as follows.
In some embodiments, it is described to the pretreated data carry out analysis include:
S301-1 obtains the lesion region PET scan image;
S301-2 identifies the lesion region in the PET scan image, calculates the area of the lesion region;The disease
Becoming region has at least one;
During PET-CT scanning, by dye injection to patient's body, patient is scanned within 15-40 minutes, is developed
The concentrated area of the concentrated area reflection lesion of agent.During the scanning process, the range of tumor markers from small to large, reaches maximum
It gradually becomes smaller again later.The area of the maximum magnitude is the area of tumour concentrated area, and it is maximum to observe by the naked eye selection
Region.As shown in Fig. 2, being a kind of tumor markers maximum region scanning figure provided in an embodiment of the present invention.Pass through computer side
Boundary's identification, turns to X-Y scheme, the size and actual area of the X-Y scheme for the tumor markers maximum region image
It is identical, the X-Y scheme is calculated.As shown in Figure 3a, the X-Y scheme is calculated for the embodiment of the present invention
Process schematic.The two dimensional image is scanned up and down, distance d is selected equidistantly to scan, every time the corresponding transverse direction 2r mark of scanning
Note scans n times altogether, forms set V, wherein V={ ri|1≤i≤n}.Collect at this point, we can be stored by queue EnQ (V)
It closes.By to riIt averages to calculate the equivalent redius of the X-Y schemeWherein,
The X-Y scheme is equivalent to by a circle by this calculation.Select different distance d corresponding different
Scanning times, then calculate different equivalent redius.The cartographic represenation of area of the equivalent circular are as follows:
It enablesObtain maximum equivalent areaMachine point for ease of calculation
Analysis, can focus on regularization for the calculating of equivalent circular.The judgement of maximum magnitude can also calculate in the shortest possible time,
To maximize image intensity.
Fig. 3 b is a kind of analysis datagram for calculating concentrated area area provided in an embodiment of the present invention.It is shown in figure logical
Cross the calculating analysis for adjusting different cutting distances (d) to machine concentrated area.Per unit adds 0.05 centimetre of unit length.When
When d=0.1cm, concentrated area areaAs △ d=0.15cm to △ d=0.35cm, concentrated area face
ProductStability is in 12 and 13cm2Between;As △ d=0.4cm,Less than 12cm2, so that segmentation range △ d ∈
[0.15,0.35].Concentration range is maximum, and in 12.8cm2Locate the cluster value with maximum stable.Testing 79226 figures
As after, we determined that △ d=0.2cm is suitable for Training valuation system.Therefore, can be obtained during scanning patient optimization and
Clear image, the data basis as assessment.
S301-3 obtains the sum of the area of lesion region SNSCLC;
The area of all lesion regions is calculated using above-mentioned same method, and is summed, details are not described herein.
S301-4 calculates the area of the concentration lesion region in the lesion regionTo describedWith it is described
SNSCLCRatio is sought, concentrated area degree of correlation D (r) is obtained;
For the equivalent redius for concentrating lesion region, i is equidistant scanning times.
In order to preferably analyze and calculate the concentration lesion region in image, we are using standard ratio calculation method to every
The clinical problem of a image and NSCLC are analyzed.Specifically, described in calculatingWith the SNSCLCRatio, described in acquisition
Concentrated area degree of correlation D (r),After the data for obtaining the concentrated area degree of correlation, we can be with
Scan each NSCLC clinical image.Clinical problem it is describedWith the SNSCLCRatio range may be used as being stored in number
According to one of the patient evaluation parameter in the system of library.
The relevant parameter of the D (t) includes: high correlation parameter and low correlation parameter.Specific analysis method is as follows:
S302-1 obtains the concentration of the tumor markers;
Blood serum tumor markers are mainly generated by the tumour cell of Healthy People, and detailed value is always in the normal range.But
In these malignant tumor patients especially patient with advanced cancer, the level of tumor markers is negatively correlated with life span.With
NSCLC high correlation parameter and the relevant primary tumor marker of decision data include cytokeratin (CYFRA21-1), cancer embryo
Antigen (CEA), the soluble fragments of cancer antigen (CA) -125, they have always been considered as being prognostic indicator, especially NSCLC's
Later stage.CYFRA21-1, CEA and (CA) -125 are set major parameter by us.
Table 2 reflects the normal range (NR) of three assessment parameters.Table 3 was shown according to the age between 35 to 78 years old
