Detailed Description
In order to further understand the objects, structures, features, and functions of the present invention, the following embodiments are described in detail.
Referring to fig. 1 and 2, fig. 1 is a schematic diagram of an ultrasonic system according to an embodiment of the invention, and fig. 2 is a functional block diagram of the ultrasonic system in fig. 1. The ultrasound system 1 includes an ultrasound probe 10 and an ultrasound scanner 12, wherein the ultrasound scanner 12 is in communication with the ultrasound probe 10. The ultrasonic probe 10 includes a tilt sensor 100. The ultrasonic scanner 12 includes a processing unit 120, a display unit 122, and a storage unit 124, wherein the processing unit 120 is coupled to the display unit 122 and the storage unit 124. The ultrasonic scanner 12 can be a computer or other electronic device with data calculation, processing and display functions. The ultrasonic scanner 12 and the ultrasonic probe 10 can communicate with each other via a cable (cable), so that when the ultrasonic probe 10 performs ultrasonic scanning on the target object, the ultrasonic scanning image can be displayed on the display unit 122 of the ultrasonic scanner 12.
In this embodiment, the processing unit 120 may be a processor or a controller with signal processing function; the display unit 122 may be a liquid crystal display panel or other display panel; the storage unit 124 may be a memory or other data storage device. Generally, the ultrasonic probe 10 and the ultrasonic scanner 12 are provided with hardware and software components necessary for operation, such as input/output ports, application programs, circuit boards, power supplies, communication modules, etc., depending on the actual application.
As shown in fig. 1, the ultrasonic probe 10 is used to perform ultrasonic scanning on the target 3. In this embodiment, the target 3 may be a human breast, but not limited thereto. In another embodiment, the target 3 may also be a specific part of the object, depending on the application.
Fig. 3 is a schematic diagram of a plurality of section templates and a plurality of switching conditions according to an embodiment of the invention. The storage unit 124 may pre-store a plurality of section templates S1 to S9 of the object 3 and a plurality of switching conditions corresponding to the plurality of section templates S1 to S9, wherein each switching condition includes a predetermined direction and a predetermined angle range. In this embodiment, the plurality of section templates S1 to S9 may include a coronal section (coronal section), a sagittal section (sagittal section), and/or a transverse section (horizontal section) according to different switching conditions, depending on the application. The section templates S1 to S9 and the switching conditions in fig. 3 may be set according to whether the object 3 is a human breast. In practical applications, the present invention can set the corresponding section template and the switching condition according to different objects. The center points of the sample planes S1 to S9 in fig. 3 may be defined as a reference point P corresponding to the ultrasonic probe 10, and the predetermined direction of the switching condition may be set according to the offset direction of the reference point P with respect to the portion 30 (e.g., nipple) of the target 3. Note that "horizontal scanning" in the switching condition means that the ultrasonic probe 10 scans the target 3 in a direction parallel to the ground; the "vertical scanning" in the switching condition refers to the ultrasonic probe 10 scanning the object 3 in a direction perpendicular to the ground.
When the ultrasonic probe 10 performs ultrasonic scanning on the target 3, the tilt sensor 100 detects the tilt direction and tilt angle of the ultrasonic probe 10. Then, the ultrasonic probe 10 transmits the tilt direction and the tilt angle detected by the tilt sensor 100 to the ultrasonic scanner 12. At this time, the processing unit 120 of the ultrasonic scanner 12 compares the tilt direction and the tilt angle of the ultrasonic probe 10 with the plurality of switching conditions in fig. 3, respectively. When the processing unit 120 determines that the tilting direction and the tilting angle of the ultrasonic probe 10 meet the predetermined direction and the predetermined angle range of one of the plurality of switching conditions, the processing unit 120 controls the display unit 122 to display one of the plurality of corresponding section templates S1 to S9.
For example, when the ultrasonic probe 10 is operated such that the reference point P is vertically shifted downward by 30 degrees with respect to the portion 30 (i.e., the tilting direction is vertically shifted downward and the tilting angle is 30 degrees), the processing unit 120 controls the display unit 122 to display the section template S4 in fig. 3; when the ultrasonic probe 10 is operated such that the reference point P is horizontally shifted to the right by 70 degrees (i.e. the tilting direction is horizontally shifted to the right, and the tilting angle is 70 degrees), the processing unit 120 controls the display unit 122 to display the section sample plate S7 in fig. 3; and so on.
Referring to fig. 4 and 5, fig. 4 is a schematic diagram of a display unit displaying a section template and a probe pattern according to an embodiment of the invention, and fig. 5 is a schematic diagram of a probe pattern according to an embodiment of the invention adjusted with an inclination direction and an inclination angle of an ultrasonic probe. In this embodiment, when the display unit 122 displays one of the plurality of section templates S1 to S9, the processing unit 120 may control the display unit 122 to display the probe pattern on the section template. As shown in fig. 4, when the display unit 122 displays the section template S7, the processing unit 120 may control the display unit 122 to display the probe pattern 126 on the section template S7. In addition, as shown in fig. 5, the processing unit 120 can adjust the orientation of the probe pattern 126 in real time according to the tilting direction and the tilting angle of the ultrasonic probe 10. Thus, the doctor can grasp the current scanning progress in real time according to the probe pattern 126.
As shown in fig. 2, the ultrasonic probe 10 further includes a track sensor 102 and a pressure sensor 104. In this embodiment, the track sensor 102 may be a photoelectric sensor, but not limited thereto. The track sensor 102 is used for sensing the moving track of the ultrasonic probe 10, and the pressure sensor 104 is used for sensing the pressure applied to the ultrasonic probe 10. After the ultrasonic probe 10 transmits the moving track sensed by the track sensor 102 and the pressure sensed by the pressure sensor 104 to the ultrasonic scanner 12, the processing unit 120 calculates the moving distance of the ultrasonic probe 10 relative to the target 3 according to the moving track and the pressure, and correspondingly moves the probe pattern 126 on the section sample plate according to the moving distance. In this embodiment, the processing unit 120 converts the pressure sensed by the pressure sensor 104 into the depth a of the ultrasonic probe 10 pressed against the target object 3. Assuming that the length of the moving track sensed by the track sensor 102 is B, the moving distance C of the ultrasonic probe 10 relative to the target 3 can be calculated by the following formula 1.
Equation 1:
then, assuming that the length of the target 3 is L and the length of the section template is L ', the corresponding moving distance C' of the probe pattern 126 on the section template can be calculated by the following formula 2.
Equation 2:
therefore, the processing unit 120 can correspondingly move the probe pattern 126 on the section sample plate by the movement distance C' according to the movement distance C of the ultrasonic probe 10 relative to the target 3. Thus, the doctor can grasp the current scanning progress in real time according to the probe pattern 126.
In this embodiment, the ultrasound system 1 further includes a positioning activation unit 128, wherein the positioning activation unit 128 is coupled to the processing unit 120 and disposed on the ultrasound scanner 12, as shown in fig. 2. In another embodiment, the positioning activation unit 128 may also be disposed on the ultrasonic probe 10 and coupled to the processing unit 120 through the ultrasonic probe 10. In other words, the positioning activation unit 128 may be selectively disposed on one of the ultrasound scanner 12 and the ultrasound probe 10, depending on the application. In practical applications, the positioning activation unit 128 may be a button, a knob, an On-Screen Display (OSD) menu or other operation interface.
The user may activate or deactivate the positioning function of the probe pattern 126 by activating or deactivating the positioning activation unit 128. Further, before performing the ultrasonic scanning on the target 3, the user may activate the positioning activation unit 128 (e.g., press the positioning activation unit 128) to activate the positioning function. When the positioning activation unit 128 is turned off, the processing unit 120 locks the probe pattern 126. At this time, the processing unit 120 stops moving the probe pattern 126 according to the operation of the ultrasonic probe 10. Then, the user can move the ultrasonic probe 10 to a position corresponding to the probe pattern 126 with respect to the target object 3 to perform the initial positioning before scanning. The user may then turn off the positioning initiation unit 128 (e.g., press the positioning initiation unit 128 again) to turn off the positioning function. When the positioning initiation unit 128 is turned off, the processing unit 120 may record the current angle sensed by the tilt sensor 100 in the storage unit 124 and unlock the probe pattern 126. At this time, the processing unit 120 starts to move the probe pattern 126 according to the operation of the ultrasonic probe 10 with the current angle as the reference angle.
Referring to fig. 6, fig. 6 is a flowchart of an ultrasonic scanning method according to an embodiment of the invention. The ultrasonic scanning method in fig. 6 is suitable for the ultrasonic system 1 in fig. 1 and 2. First, step S10 is executed to provide a plurality of section sample plates S1 to S9 of the object 3 and a plurality of switching conditions corresponding to the plurality of section sample plates S1 to S9, wherein each switching condition includes a predetermined direction and a predetermined angle range, as shown in fig. 3. Next, step S12 is executed to perform ultrasonic scanning on the target 3 by the ultrasonic probe 10. Next, step S14 is executed to detect the tilting direction and the tilting angle of the ultrasonic probe 10. Then, step S16 is executed to display one of the tangent plane templates S1 to S9 when the tilt direction and the tilt angle meet the predetermined direction and the predetermined angle range of one of the switching conditions.
When one of the section templates S1 to S9 is displayed, the ultrasonic scanning method of the present invention can further display the probe pattern 126 on the section template, as shown in fig. 4. In addition, the ultrasonic scanning method of the present invention can further adjust the orientation of the probe pattern 126 according to the tilting direction and the tilting angle of the ultrasonic probe 10, as shown in fig. 5.
In another embodiment, the ultrasonic scanning method of the present invention can detect the moving track of the ultrasonic probe 10 and detect the pressure applied to the ultrasonic probe 10. Then, the ultrasonic scanning method of the present invention can calculate the moving distance of the ultrasonic probe 10 according to the moving track and the pressure. Then, the ultrasonic scanning method of the present invention can correspondingly move the probe pattern 126 on the section template according to the moving distance.
In another embodiment, the ultrasonic scanning method of the present invention can provide the function of positioning the probe pattern 126. When the positioning function is activated, the ultrasonic scanning method of the present invention can lock the probe pattern 126. On the other hand, when the positioning function is turned off, the ultrasonic scanning method of the present invention records the current angle of the ultrasonic probe 10 and unlocks the probe pattern 126.
It should be noted that the detailed embodiments of the ultrasonic scanning method of the present invention are described above, and are not described herein again. In addition, each part or function of the control logic of the ultrasonic scanning method of the present invention can be implemented by a combination of software and hardware.
In summary, when the ultrasonic probe performs ultrasonic scanning on the target object, the tilt sensor of the present invention detects the tilt direction and the tilt angle of the ultrasonic probe. Then, the ultrasonic scanner can automatically switch the corresponding section template according to the inclination direction and the inclination angle of the ultrasonic probe. Therefore, the doctor does not need to spend time on manually switching the section sample plate, thereby improving the efficiency of ultrasonic scanning and diagnosis. In addition, the present invention can display the probe pattern on the section sample plate, adjust the orientation of the probe pattern according to the tilting direction and the tilting angle of the ultrasonic probe, and/or correspondingly move the probe pattern on the section sample plate according to the moving distance of the ultrasonic probe. Therefore, the doctor can grasp the current scanning progress in real time according to the probe pattern.
