Description
Technical Field
The invention relates to the field of medical equipment, in particular to a mammography system and a mammography method thereof.
Background
With the development of computer science and information technology, medical imaging technology has also been rapidly developed, and various medical imaging systems are emerging continuously. A Mammography (mammogram) system and a Digital Breast Tomography (DBT) system are widely used as a screening and diagnosis system for breast cancer.
When using mammography systems for examination, the workflow for examination typically includes: (1) patient registration, such as registration of patient Information, examination Information, etc. by hand, Hospital Information System (HIS), or other means. (2) The patient is selected, i.e. the operator selects the patient to be examined from a list of patients. (3) Selecting an examination protocol, i.e. a protocol corresponding to the current examination of the patient, said examination protocol generally comprising: the frame positioning information, exposure parameters, exposure dose, image algorithm and the like. (4) A compression system, such as a compression plate, is installed. (5) The height of the rotating arm is adjusted, so that the patient with different heights can be checked in different body positions, and the height of the rotating arm needs to be adjusted according to the position of the breast of the patient, so that the object stage can reach the position suitable for placing the breast of the patient. (6) The angle of the rotating arm is adjusted, and according to the rack positioning information in the inspection protocol, an operator can manually adjust the rotating arm to a specified angle and can also automatically rotate the rotating arm to the specified angle in the inspection protocol through a system. (7) And (3) compressing, wherein an operator can compress the breast of the patient by adopting a manual compression mode or an intelligent compression mode. (8) And acquiring an image, such as exposure in an AEC mode or a manual mode, acquiring the image and performing corresponding processing to obtain the image meeting clinical requirements.
In the above-mentioned examination process, an examination protocol is selected first, and then corresponding positioning is performed, for example, after positioning the frame, corresponding positioning is performed on the patient, and in practical applications, after positioning the frame and the patient is completed, it may be found that the current positioning is inconsistent with the positioning information in the selected examination protocol, for example: the doctor needs to examine the left breast of the patient in the head-tail position and the inner-outer oblique position in sequence, and after the left breast of the first patient is examined in the head-tail position and the inner-outer oblique position in sequence, the following situations may occur:
the doctor selects the examination protocol of the head and tail position according to the current examination sequence, then enters the examination room to finely adjust the height of the rotating arm to compress the left breast of the second patient, and the rack is in the position-setting state during the examination of the inner and outer oblique positions, so that the position-setting information in the examination protocol is inconsistent with the current position-setting of the patient, namely the current position-setting of the patient is the inner and outer oblique positions, and the corresponding position-setting in the examination protocol is the head and tail position, at the moment, the doctor can return to the operation room to reselect the examination protocol, but the workflow is complicated. Or the patient is repositioned, namely the left breast of the patient is decompressed firstly, then the frame is controlled to be repositioned to the head-tail position, and the left breast of the patient is compressed, so that discomfort is brought to the patient on one hand, and the workflow is complicated on the other hand.
In addition, when the second patient is photographed, the doctor may perform the positioning of the second patient in a current positioning state of the rack (the rack is in a positioning state of the inner and outer oblique positions), so that during the examination process of the doctor, the examination protocols of the odd number of patients are selected by sequentially selecting the head and tail positions and the inner and outer oblique positions, and the examination protocols of the even number of patients are selected by sequentially selecting the inner and outer oblique positions and the head and tail positions.
In addition, for a patient suffering from disability, if the head and tail positions and the internal and external oblique positions are also required to be checked, if a doctor selects the internal and external oblique positions according to the habit of the doctor, when the patient enters an examination room, the doctor judges that the patient is suitable for taking the head and tail positions firstly and then takes the internal and external oblique positions according to the current state of the patient, at the moment, the selected examination protocol does not accord with the current positioning required by the doctor, and if the patient positions the machine frame and the patient firstly and then returns to an operation room to select the examination protocol again, the workflow is complicated; it may cause discomfort to the patient if he positions the patient according to the examination protocol that has been selected.
Therefore, how to provide a mammography system to simplify the workflow during the examination process and improve the work efficiency of the operator is one of the problems to be solved.

The breast selection information is to select to compress the left breast or the right breast of the subject, and the breast position information is to compress the head and tail position, the internal and external oblique side and other positions of a certain breast in the compression process (regarding the positioning of the breast, the meaning of different positioning defined in practical clinical application can be referred, which is not mentioned here). In this embodiment, the positioning information obtaining unit 10 includes: a gantry positioning information acquisition unit 101, a breast selection recognition unit 102 and a determination unit 103.

The breast selection identifying unit 102 according to the embodiment of the present invention is described in detail below with reference to fig. 1 and 2. Referring to fig. 2, fig. 2 is a schematic diagram of a mammography system according to a first embodiment of the present invention, and before describing the breast selection recognition unit 102 according to the first embodiment of the present invention, the mammography system in fig. 2 will be briefly described.
As shown in fig. 2, the mammography system 1 includes: the device comprises a vertical column 2, a rotating arm 3, a bulb 4, a compression plate 5 and a housing 6 (the compression plate is arranged on the upper surface of the housing 6). The gantry of a mammography system typically comprises a column 2 and a rotating arm 3. The bulb 4 is an X-ray source which generates X-rays during the photographing process, the compression plate 5 is used for compressing the breast during the photographing process, and the housing 6 is provided with a detector which is used for receiving the X-rays which penetrate through the breast of the examinee during the photographing process to generate a medical image.
Example one
In this embodiment, the breast selection recognizing unit 102 includes a triggering unit as an example. Specifically, the trigger unit includes infrared emission unit 1021 and infrared receiving unit, infrared emission unit 1021 sets up on the swinging boom 3, in this embodiment, infrared emission unit 1021 sets up in the left side of swinging boom 3, and infrared receiving unit then can set up on the wall in inspection room, and in other embodiments, infrared emission unit also can set up the right side at the swinging boom.
In the examination process, if the breast on the right side of the examinee is compressed, the body of the examinee moves leftwards without fail, the infrared transmitting unit 1021 and the infrared receiving unit which are arranged on the left side of the rotating arm 3 cannot work normally due to the blocking of the body, at the moment, the infrared receiving unit can send corresponding trigger signals to the judging unit, the trigger signals are related to the compressed breast, namely when the signals between the infrared transmitting unit and the infrared receiving unit on the left side are interrupted, the trigger signals sent by the infrared receiving unit actually represent that the breast on the right side is compressed, and after the judging unit receives the trigger signals sent by the infrared receiving unit on the left side, the judging unit learns that the infrared receiving unit on the left side stops working, and then judges that the currently compressed breast on the right side of the examinee is compressed. If the left breast of the examinee is compressed, the body of the examinee is certainly moved to the right, no blocking exists between the infrared transmitting unit 1021 and the infrared receiving unit which are arranged on the left side of the rotary arm 3 at the moment, the infrared receiving unit sends corresponding trigger signals to the judging unit, the trigger signals are related to the compressed breast, namely when the signals between the infrared transmitting unit and the infrared receiving unit on the left side are not interrupted, the trigger signals sent by the infrared receiving unit actually represent that the left breast is compressed, and the judging unit learns that the infrared receiving and transmitting unit on the left side is in a working state after receiving the trigger signals sent by the infrared receiving unit on the left side, so that the currently compressed breast on the left side of the examinee is judged.
That is, for the infrared emitting unit disposed on the left side of the rotating arm, when the compression plate is in a compressed state, the infrared emitting unit and the infrared receiving unit work with each other, so that the left breast is compressed, and when the infrared emitting unit and the infrared receiving unit stop working with each other, the right breast is compressed.
Similarly, for the infrared transmitting unit arranged at the right side of the rotating arm, when the compression plate is in a compressed state, the infrared transmitting unit and the infrared receiving unit work, the right breast is compressed, and when the infrared transmitting unit and the infrared receiving unit stop working, the left breast is compressed.
The specific arrangement of the infrared emission unit on which side of the rotating arm can be determined according to actual requirements.
In another embodiment, the trigger unit is disposed at a position different from that of the present embodiment, and the infrared emission unit of the trigger unit is disposed on a housing accommodating the detector. Still referring to fig. 2, in fig. 2, the housing 6 includes an upper surface and a side surface perpendicular to each other, the upper surface is parallel to a ground plane, and the infrared emitting unit 1021 'of the triggering unit may be disposed on the side surface of the housing 6, that is, the infrared emitting unit 1021' may be disposed on either the left side surface or the right side surface of the housing 6. The infrared receiving unit can be arranged on the wall of the inspection room as long as the communication between the infrared receiving unit and the wall is ensured.
It should be noted that in practical applications, the form of the mammography system is different, in this embodiment, the infrared emission unit of the trigger unit is disposed on the rotating arm, and in other embodiments, for example, the rotating arm of the mammography system does not include the circular base body shown in fig. 2, and is only a C-shaped arm, in which case, the infrared emission unit of the trigger unit may be disposed on the upright post 2. Therefore, the infrared emission unit is arranged at a position which only needs to ensure that the body of the examinee can block the infrared emission unit in the examination process.
In a further embodiment, the triggering unit may also be provided on the armrest, and in particular, the triggering unit may include: a touch sensor. With continued reference to fig. 2, the arm rests are fixed to the gantry in fig. 2. generally, during examination, the left hand of the subject typically rests on the left arm rest when the breasts on the right side of the subject are compressed, and the right hand of the subject typically rests on the right arm rest when the breasts on the left side of the subject are compressed.
If a touch sensor is provided on the left armrest, when the right breast of the examinee is compressed, the left hand touches the touch sensor provided on the left armrest, the touch sensor sends a trigger signal (such as a high level "1") to the determination unit, and the determination unit determines that the currently compressed breast is the right breast of the examinee after receiving the trigger signal sent by the left touch sensor. When the left breast of the examinee is compressed, the left hand of the examinee does not touch the touch sensor on the left armrest any more, the left touch sensor sends a trigger signal (such as a low level "0") to the judging unit after detecting the change of the touch signal, and the judging unit judges that the currently compressed left breast of the examinee is compressed after receiving the trigger signal sent by the left touch sensor.
Similarly, a touch sensor may be disposed on the right armrest, and when the touch sensor is disposed on the right armrest, the signal triggered by the touch sensor and the determination unit determine whether the compressed breast is the left or the right side of the subject is similar to the case where the touch sensor is disposed on the left armrest, which is not described herein again.
In another embodiment, the triggering unit includes a pressure sensor, that is, the pressure sensor may be used instead of the contact sensor, and similarly, the pressure sensor may be disposed on the armrest, taking the example that the pressure sensor is disposed on the right armrest, when the pressure sensor on the right armrest senses that the pressure is present, that is, senses the pressure, a triggering signal (for example, a high level "1") is sent to the determining unit, and the determining unit determines that the currently compressed breast on the left side of the subject is the breast on the right side of the subject after receiving the triggering signal sent by the pressure sensor on the right side. When the pressure sensor on the right armrest senses the pressure from the existence to the nonexistence, namely senses the pressure loss, a trigger signal (such as low level '0') is sent to the judging unit, and the judging unit judges that the currently compressed breast on the right side of the examinee is the breast on the right side of the examinee according to the trigger signal. When pressure sensor sets up on the handrail of left side, the signal and the judgement unit that pressure sensor triggered judge that the breast that the person of being examined is oppressed is the left side or the right side and sets up pressure sensor on the handrail of right side similar, and it is similar here no longer repeated.
The breast selection recognition unit 102 transmits selection information of the compressed subject breast to the determination unit 103 after determining the compressed breast of the subject, that is, after determining whether the subject is compressed in the left breast or the right breast.
The determination unit 103 determines the current positioning information of the subject as follows according to the gantry positioning information sent by the gantry positioning information acquisition unit 101, such as the rotating arm of the mammography system rotates counterclockwise by 45 degrees (viewed from the direction of the subject facing the mammography system) and the compressed breast sent by the breast selection recognition unit 102 is the right breast: the right breast is in oblique position. The determination unit 103 may be provided in a system control unit, or its function may be realized by the system control unit.
The positioning information acquiring unit 10 sends the current positioning information of the examinee as the information that the internal and external inclinations of the right breast are compressed to the matching unit 11, and the matching unit 11 determines the pre-stored examination protocol matched with the current positioning information of the examinee according to the current positioning information of the examinee, namely, the two characteristics of the internal and external inclinations of the right breast are matched with the pre-stored examination protocol according to the positioning information of the examinee so as to find the examination protocol related to the compression of the internal and external inclinations of the right breast. The subject's breast is then photographed (exposed) with the subject's current pose information and an examination protocol that matches the pose information to obtain an image that meets actual clinical needs. Because the examination protocol is determined according to the actual positioning information of the examinee in the process of acquiring the breast image, the condition that the examination protocol is inconsistent with the actual positioning information of the examinee in the examination process can not occur, the workflow in the examination process is simplified, the efficiency of an operator is improved, and the comfort of the examinee is improved to a certain extent.
Example two
The difference between this embodiment and the first embodiment is that the breast selection and identification unit in this embodiment includes two triggering units, specifically:
the triggering unit includes an infrared emitting unit 1021 (refer to fig. 2) and an infrared receiving unit (not shown in the figure), in fig. 2, the infrared emitting unit 1021 is arranged at the left side of the rotating arm 3, and the infrared receiving unit can be arranged on the wall of the inspection room. On the right side of the rotary arm 3, an infrared emitting unit (not shown in fig. 2) identical to the infrared emitting unit 1021 is also provided, and accordingly an infrared receiving unit corresponding to the infrared emitting unit is also provided on the wall of the examination room.
In the examination process, if the breast on the right side of the examinee is compressed, the body of the examinee moves leftwards without fail, the infrared transmitting unit 1021 and the infrared receiving unit which are arranged on the left side of the rotating arm 3 cannot work normally due to the blocking of the body, at the moment, the infrared receiving unit can send corresponding trigger signals to the judging unit, the trigger signals are related to the compressed breast, namely when the signals between the infrared transmitting unit and the infrared receiving unit on the left side are interrupted, the trigger signals sent by the infrared receiving unit actually represent that the breast on the right side is compressed, and after the judging unit receives the trigger signals sent by the infrared receiving unit on the left side, the judging unit learns that the infrared receiving unit on the left side stops working, and then judges that the currently compressed breast on the right side of the examinee is compressed.
When the left breast of the examinee is pressed, the trigger unit consisting of the infrared transmitting unit arranged on the left side of the rotating arm and the infrared receiving unit corresponding to the infrared transmitting unit sends a trigger signal for signal interruption of the left infrared transmitting and receiving unit to the judging unit, and when the left breast of the examinee is pressed, the trigger unit consisting of the infrared transmitting unit arranged on the right side of the rotating arm and the infrared receiving unit corresponding to the infrared transmitting unit sends a trigger signal for signal interruption of the right infrared transmitting and receiving unit to the judging unit; the judging unit judges that the currently compressed breast is the right breast after receiving a trigger signal of signal interruption of the left infrared receiving and transmitting unit; and the judging unit judges that the currently compressed breast is the left breast after receiving the trigger signal of the signal interruption of the right infrared receiving and transmitting unit.
In another embodiment, the infrared emission unit 1021 'of the trigger unit may be disposed on a side surface of the housing 6 (see fig. 2), that is, the infrared emission unit 1021' may be disposed on both left and right side surfaces of the housing 6.

In a further embodiment, the trigger unit comprises a touch sensor, which may be provided on both a left hand armrest and a right hand armrest of the mammography system. When the right breast of the examinee is compressed, the left hand of the examinee touches the touch sensor arranged on the left handrail, the left touch sensor sends a trigger signal to the judging unit, and the judging unit judges that the currently compressed breast on the right side of the examinee is the breast on the right side of the examinee after receiving the trigger signal sent by the left touch sensor. When the left breast of the examinee is compressed, the right hand touches the contact sensor arranged on the right handrail, the right contact sensor sends a trigger signal to the judging unit, and the judging unit judges that the currently compressed left breast of the examinee is the breast of the examinee after receiving the trigger signal sent by the right contact sensor.
In a further embodiment, the triggering unit comprises a pressure sensor, i.e. a pressure sensor may be used instead of a touch sensor, and likewise a pressure sensor may be provided on both the left hand armrest and the right hand armrest. When the left pressure sensor senses pressure, a trigger signal is sent to the judging unit, and the judging unit judges that the currently compressed breast on the right side of the examinee is the breast on the right side of the examinee after receiving the trigger signal sent by the left pressure sensor; after receiving the trigger signal sent by the right pressure sensor, the left breast of the examinee is judged to be compressed currently.
In summary, in the present embodiment, the breast selection identifying unit may include two triggering units, so that the determining unit can identify whether the left breast or the right breast is currently compressed by the triggering signals sent by the different triggering units.
In this embodiment, the rack positioning information obtaining unit, the determining unit, and the matching unit are similar to those in the first embodiment, and are not described herein again.
