Will be described in explaining the example of report creation method.User reads medical imaging to be explained from data base 22, And including in image display area 310.Various functions of the user using perusing medical images device as above, in detail Observation medical imaging.User observes result described in report display area 320, used as explanation text.In figure 3, solve annotations Originally it is described as free text.It may, however, also be structured text.Then, user's select button 321 come arrange for explain The concern position of text.Concern position is set using 35 (not shown) of operating unit.For example, user is by using pointer device Concern position is clicked on, concern position is set.Concern position method to set up is certainly not limited to this, and any method is all available , as long as the positional information (hereinafter referred to as paying close attention to positional information) for paying close attention to position can be specified.Concern position Confidence breath is including the coordinate figure in such as medical imaging.In figure 3, symbol 311 is depicted on set concern position.So And, concern positional information is recorded in medical image display apparatus 10, it is not always necessary to which the symbol of position is paid close attention in description Number.Medical image display apparatus 10 will explain that text and concern positional information (or region-of-interest information) are stored in number in association According in storehouse 22.Therefore, in step S202, read and explain text and concern positional information, as explanation report.

In step S203, keyword extraction unit 43 passes through keyword match, from the explanation read in step S202 Text, extracts the keyword for pre-setting.In this embodiment, keyword is the character string for representing anatomic information, such as in doctor With the Organ naming shown in image.Example is brain, cerebellum, eyeball, nose, tooth, lung, bronchus, heart, liver, spleen, pancreas Dirty, stomach, large intestine, small intestinal, jejunum, ileum, rectum, prostate, uterus, forearm, upper arm, thigh, lower lower limb, breast, muscle, bone Bone, spinal column, celestial bone, coccyx and pelvis.Organ naming described here is only example certainly, the invention is not restricted to this.Close Key word is not limited to Organ naming, and can be arbitrary string, as long as the position in medical imaging can be specified.Under Face will describe as shown in Figure 3, " solid nodules are observed in right lung S2 regions " and be described as explaining the explanation text of report Example.In this case, " lung " is extracted as keyword.It is alternatively possible to arrange and extract tighter specify " right lung " of the position in medical imaging or " right lung S2 ".Note, here extracts keyword by keyword match, but Can also be extracted using additive method (such as known natural language processing).

In step S204, area acquisition unit 44 is extracted from the medical imaging for obtaining in step s 201 and in step The corresponding anatomic region of the keyword that extracts in S203, and the region is obtained as the region relevant with region-of-interest.Will The situation that " lung " in step S203 is extracted as keyword is described in, as an example.In this example, area acquisition unit 44 from Medical imaging obtains lung areas.More specifically, using smoothing filter, carry out from the medical imaging for obtaining in step s 201 Noise remove.Next, for the pixel value of medical imaging, using predetermined threshold (for example, HU values：- 200) carry out at binaryzation Reason, so as to medical imaging is separated into interior zone and perimeter.Using another threshold value (for example, HU values：- 500) will separate Interior zone be separated into lung areas and other regions, so as to extracting and obtaining lung areas.Note, at anatomic region extraction Reason only needs to extract predetermined region from the medical imaging for reading, and is not limited to the method.It is, for example possible to use other devices Official's dividing processing (such as pattern-cutting method) is extracting anatomic region.

In step S205, Overlapping display in the 45 pairs of medical imagings for reading in step s 201 of display location determining unit The some or all of display location of the character string of the explanation text read in being formed in step S202 is determined.In the reality Apply in example, viewing area is confirmed as not making the viewing area of explanation text overlap with anatomic region.Will be with reference to Fig. 4, Fig. 5 A, figure 5B, Fig. 5 C and Fig. 5 D describe display location and determine method.Medical imaging 410 shown in Fig. 4 is represented Medical imaging.In this example, medical imaging is axial direction (level) image shot by chest X-ray CT devices, and is cut Piece position is the position in step S202 arranging concern position.Hereinafter, the image at the slice position will be claimed To pay close attention to sectioning image.Dotted line 411 represents the boundary line between the lung field in medical imaging 410 and outside.Symbol 412 represents disease Change portion (tuberosity).Character string display region 420 represents the word of the explanation text (annotation information) read in being displayed in step S202 The region of some or all character strings (will hereinafter being referred to as showing character string) of symbol string (will hereinafter be referred to as character String viewing area).In this embodiment, character string display region 420 has predetermined size and shape.In this case, If there are many display character strings relative to character string display region, can show all in character string display region Display character string.In this case, as by represented by character string display region 421, it is possible to use scroll bar 422 is rolled It is dynamic to show character string.As, by represented by character string display region 423, shown, the font of character string can be changed in character String shows all of display character string in viewing area.It is alternatively possible to hide show character string in, word cannot be displayed on Character string in symbol string viewing area, or plucking for display character string can be automatically generated using known natural language processing Want and shown.

Character string display region 420 is described below and is applied situation about being displayed in medical imaging 410.Note, will say Bright following example, wherein, in step S203, " lung " is extracted as the keyword for explaining text, and obtains in step S204 Take the lung areas in medical imaging 410.

Display location determining unit 45 is based on predetermined condition (hereinafter referred to as display location determines condition), determines word The display location of symbol string viewing area 420.Display location will be given and determine that " whole character string display region is located at medical figure to condition As internal " and " character string display region is not overlapping with the inside in the region extracted based on the keyword for explaining text " show Example, is described.In this case, the display location of character string display region 420 is confirmed as inside medical imaging 410 And the region outside dotted line 411.Fig. 5 A, Fig. 5 B, Fig. 5 C and Fig. 5 D show the example of display location.In Fig. 5 A and Fig. 5 B, The display location of character string display region 420 is located inside medical imaging 410 and outside dotted line 411.Therefore, in Fig. 5 A and Fig. 5 B The display location of shown character string display region is qualified appropriate display location.In figure 5 c, character string display The display location in region 420 is located at outside dotted line 411, but is positioned partially at outside medical imaging 410.Therefore, shown in Fig. 5 C The display location of character string display region be ineligible unsuitable display location.In figure 5d, character string display The display location in region 420 is located inside medical imaging 410 and inside dotted line 411.Therefore, character string shown in Fig. 5 D shows The display location for showing region is ineligible unsuitable display location.

Only condition is determined by two above-mentioned display locations, it is impossible to uniquely determine the display position of character string display region Put.Therefore, in the above-mentioned example, the display location of character string display region can meet above-mentioned display location to determine Any position in the medical imaging of condition.In order to uniquely determine the display location of character string display region, it is additionally provided in Display locations such as " the distance between center of concern position and character string display region become most short " determines condition.Fig. 6 Show the example using medical imaging 410 and character string display region 420.The concern position that calculating is obtained in step S202 413 the distance between with the center 421 of character string display region 420.Character string display region 420 is displayed on such position Put, i.e. while meeting other display locations and determining condition, make the distance between center most short.

In step S206, in the character string of the explanation text that display processing unit 46 is obtained in being included within step S202 Some or all of character string display region, at the display location determined in step S205, superposition obtain in step s 201 In the medical imaging for taking.Display processing unit 46 carries out display control, with display unit 36 to be superimposed with including solution annotations The medical imaging of this character string display region is shown.

As described above, according to the medical image display apparatus 10 of the embodiment, being obtained in that following effect.That is, when will solution It is when some or all Overlapping displays in the character string of annotations sheet are in medical imaging, aobvious to determine according to the content for explaining text Show position.The area closely related with the content of text is explained of medical imaging is displayed in therefore, it is possible to avoid character string from being applied On domain.For this reason, even if when viewing is superimposed with the medical imaging of character string, also without prejudice to user confirms character string Content, and allow users to more easily grasp medical imaging and explain the corresponding relation between report.

If in conference system etc., the user in addition to exponent is then solved to removing with reference to report and medical imaging is explained For user beyond the person of releasing, it is generally difficult to understand the content for explaining report.Equally in this case, when the solution for explaining report Annotations sheet together with medical imaging, when being displayed at the overlapping position in not related to region-of-interest region, then except solution User beyond the person of releasing can more easily grasp medical imaging and explain the corresponding relation between report.In the present embodiment, Due to determining the display location of character string display region in the region by occupied by medical imaging, so explaining that text is shown Near the corresponding region of medical imaging, and can readily recognize between explanation text and the corresponding region of medical imaging Relation.

Note, in this embodiment, it is considered to do not make character string display region and and the concern of explanation text (annotation information) The related region in region overlaps.Have been described with including that the anatomic region of region-of-interest is acquired as the area related to region-of-interest The example in domain.However, relevant range not limited to this.That is, relevant range can be when browse explain text when be referred to, by The arbitrary portion region in the region occupied by subject in medical imaging.For example, when for right lung disease establishment explanation text When, when it is determined that explaining the display location of text, the region occupied by right lung open country not only can be considered, it is also contemplated that by can be with The region that related other organs (for example, left lung field and bronchus) of disease are occupied.For diseases such as the cancers that may be shifted Disease, the region that disease present in region-of-interest may be transferred to can be acquired as relevant range.Alternatively, away from concern position The scope of preset distance (for example, 10 centimetres) can be acquired as relevant range.

Additionally, according to the modification for explaining text (annotation information), display location determining unit 45 can change explanation text Character string display region display location, and display processing unit 46 can be shown after the change on display unit 36 The amended medical imaging for explaining text is superimposed with display location.Change explanation text when the modification according to explanation text Display location of the character string display region in medical imaging when, user always easily can grasp explanation text with it is corresponding Corresponding relation between the region of medical imaging of text is explained.

According to by area acquisition unit 44 from explaining extraction of the character string that includes of text to keyword, display processing list Unit 46 can show the part corresponding with the keyword in character string, to distinguish with other character strings.It is, for example possible to use The character color different from other parts or background color are showing the part corresponding with keyword.Under the part can be added Rule, shown using different fonts, or highlighting.This allows users to identify the pass for explaining that text includes at a glance Key word, and easily grasp the content for explaining text.

In this embodiment, it has been described that determine solution annotations based on the keyword of character string that text includes is explained The example of the display location of this character string display region.However, it is not necessary to the character for explaining text is always determined based on keyword The display location of string viewing area, as long as explaining that the character string display region of text is not overlapping with the relevant range of region-of-interest i.e. Can.For example, relevant range can be used as by the position acquisition anatomic region based on the region-of-interest in medical imaging, is determined Explain the display location of the character string display region of text.Alternatively, if anatomic region cannot be obtained based on character string, as In the case where explaining that text does not include keyword, anatomical area can be obtained based on the position of the region-of-interest in medical imaging Domain.Therefore, explain text can be shown as not with the case where key word is not used, with high probability with will be together with solution Annotations is originally overlapped by the anatomic region of reference together, and can more easily be grasped medical imaging and be explained right between report Should be related to.

The image file including the medical imaging for explaining text and display location information, display location information table can be created Show the display location of the character string display region determined by display location determining unit 45.Therefore, as long as device being capable of loading figure As file, even the device of the function not with the medical image display apparatus 10 according to the embodiment, it is also possible to read figure As file and it is output to display to show the relation between text and corresponding region explained.For example, the lattice of image file Formula can be DICOM.The information of the region-of-interest explanation text (annotation information) corresponding with region-of-interest and showing is explained The information of the viewing area of text (annotation information), is included in DICOM image files.Annotation information and the letter of viewing area Breath is retained as the data corresponding with the annotation of the GSPS for for example being defined by DICOM.It is in present condition that GSPS is gray scale soft copy The abbreviation of (Grayscale Softcopy Presentation State).Show that above-mentioned explanation text (annotation information) shows The information of the sectioning image in region is also included in DICOM image files.

The character string display region for explaining text can be moved according to the operation input of user.For example, it is assumed that being made that Character string display region (the first viewing area) is moved to overlapping with the relevant range of region-of-interest (the second viewing area) The operation input of position.In this case, the display location of at least one of the first viewing area and the second viewing area, It is confirmed as not making the first viewing area and the second viewing area overlap each other.This is prevented from the character string display for explaining text Region is overlapping with relevant range before and after the movement of character string display region of text is explained, and clearly can show Show medical imaging and explain the corresponding relation between text.

In the above-described embodiments, as will in step S203 from explain Text Feature Extraction keyword, pre-set expression The character string of anatomic information (Organ naming that such as will be shown in medical imaging).However, the keyword for pre-setting is not limited In this.For example, disease name, tuberosity, cancer, pneumonia, emphysema or mycobacterial diseaseses etc. can be set.

Here, the character string display region being described in reference picture 7A in the case that " tuberosity " is arranged to crucial word shows Location determining method.Medical imaging 410, dotted line 411 and black circle 412 in Fig. 7 A with it is identical shown in Fig. 4.

In step S202, " solid nodules are observed in right lung S2 regions " is acquired as explaining text.In step In S203, as " tuberosity " is arranged to crucial word, so from explanation Text Feature Extraction " tuberosity ".In step S204, from medical Image obtains the region of " tuberosity ".Processed by the region segmentation of pattern cut process etc., carry out the region of tuberosity Extract.
