Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart of an implementation of an ultrasound image processing method according to an embodiment of the present application, which may include:
step S11: the depth range to which the currently displayed ultrasound image belongs (denoted as the first depth range for convenience of description) is determined.
The first depth range is at least a part of a maximum depth range scanned when the irradiation object is scanned by the ultrasound imaging apparatus, that is, in this embodiment, the currently displayed ultrasound image may be an image within the maximum depth range of the irradiation object when the irradiation object (for example, the abdomen, the thorax, and the like of a human body) is scanned by the ultrasound imaging apparatus, or may be an image within a partial depth range of the irradiation object, that is, a local part of the irradiation object. Generally, zooming in on an ultrasound image within the maximum depth range of the scanned object may result in an ultrasound image of the part of the illuminated object.
For example, if the maximum depth from the body surface to the inside of the body is 11cm when the thorax of the human body is scanned, the maximum depth range scanned by the ultrasonic imaging device when the thorax of the human body is scanned is 0-11cm, and the currently displayed ultrasonic image may be an image in the range of 0-11cm, or may be any part of an image in the range of 0-11cm, for example, an image in the range of 3-8 cm.
Step S12: and dividing the currently displayed ultrasonic image into N sections according to the first depth range to obtain N sections of ultrasonic images. N is a positive integer, which is the number of all time gain compensation parameter adjustment keys provided by the ultrasound imaging apparatus, and the value of N may be 6 or 8, or may be a larger value, such as 10.
The depth range of each section of ultrasonic image is a sub-range of the first depth range, and the depth ranges of the N sections of ultrasonic images are combined to obtain the first depth range.
When the currently displayed ultrasound image is divided, the currently displayed ultrasound image may be divided into N segments on average, or divided into N segments non-uniformly.
Specifically, when dividing, there may be two optional implementations:
the first method is as follows:
the currently displayed ultrasonic image is directly and averagely divided into N sections according to a first depth range, and the difference between the maximum depth value and the minimum depth value of each section of ultrasonic image is the same.
The second method comprises the following steps:
determining a region of interest of the user and a third depth range to which the region of interest of the user belongs according to a region of interest mark marked on the currently displayed ultrasonic image by the user; according to a third depth range, averagely dividing the region of interest of the user into M sections of first-class ultrasonic images, and dividing the region of the currently displayed ultrasonic image except the region of interest of the user into P sections of second-class ultrasonic images, wherein M is the depth of the currently displayed ultrasonic image<N，P<And N, wherein M + P is equal to N, and the difference between the maximum depth value and the minimum depth value of the first type of ultrasonic image is smaller than the difference between the maximum depth value and the minimum depth value of the second type of ultrasonic image. For example, assume that the maximum depth value of a first type of ultrasound image is d1maxThe minimum depth value is d1minThe maximum depth value of a second type ultrasonic image is d2maxThe minimum depth value is d2minThen (d)1max-d1min)<(d2max-d2min)。
Step S13: and establishing a one-to-one correspondence relationship between the preset N time gain compensation TGC parameter adjusting keys and the N sections of the ultrasonic images obtained by division. Wherein, the N time gain compensation parameter adjusting keys are all time gain compensation parameter adjusting keys provided by the ultrasonic imaging equipment.
The TGC parameter adjusting keys can be virtual keys or physical keys, and can be sliding blocks sliding on a sliding rod, the sliding directions of the sliding blocks on the sliding rod are different, and the adjusting directions of the TGC parameters are different. For example, if the TGC parameter increases when the slider slides on the slide bar in a first direction, the TGC parameter decreases when the slider slides on the slide bar in a second direction; the sliding distance of the sliding block on the sliding rod is different, and the adjustment amount of the TGC parameter is different, for example, generally, the larger the sliding distance of the sliding block on the sliding rod is, the larger the adjustment amount of the TGC parameter is, and conversely, the smaller the sliding distance of the sliding block on the sliding rod is, the smaller the adjustment amount of the TGC parameter is.
As shown in fig. 2, fig. 2 is a diagram illustrating an example of the mapping relationship between the N TGC parameter adjustment keys (shown in fig. 2-a) and the ultrasound image (shown in fig. 2-B) when the currently displayed ultrasound image is an image within the maximum depth range. In this example, there are 8 TGC parameter adjustment keys, and the depth of the ultrasound image gradually increases from top to bottom.
Fig. 3 is a diagram illustrating an example of a mapping relationship between TGC parameter adjustment keys (as shown in fig. 3-a) and an ultrasound image (as shown in fig. 3-B) when a currently displayed ultrasound image is an image in a local depth range (an image displayed after the ultrasound image shown in fig. 2 is enlarged) in the prior art. In the prior art, only part of the TGC parameter adjustment keys are mapped to the currently displayed ultrasound image, that is, in the example shown in fig. 2, which ones of the TGC parameter adjustment keys (in this example, the 3 rd TGC parameter adjustment key to the 6 th TGC parameter adjustment key) correspond to the images within the local depth range in fig. 3, and which ones of the TGC parameter adjustment keys still correspond to the enlarged ultrasound image.
Fig. 4 is an exemplary diagram of the mapping relationship between the TGC parameter adjustment key (as shown in fig. 4-a) and the ultrasound image (as shown in fig. 4-B and the same as fig. 3-B) in the case where the currently displayed ultrasound image is an image in the local depth range (an image displayed after the ultrasound image shown in fig. 2 is enlarged) in the present embodiment. In the present application, all TGC parameter adjustment keys are mapped to the currently displayed ultrasound image, that is, regardless of which TGC parameter adjustment keys correspond to the image in the local depth range in fig. 4 in the example shown in fig. 2, after the ultrasound image is enlarged, all TGC parameter adjustment keys are the ultrasound image displayed after being enlarged.
In the embodiment of the application, regardless of the depth range to which the currently displayed ultrasound image belongs, the currently displayed ultrasound image is divided into N sections according to the depth range to which the currently displayed ultrasound image belongs; the preset N time gain compensation parameter adjusting keys are in one-to-one correspondence with the N divided ultrasonic images, so that when the currently displayed ultrasonic image is a local image, any one of the N TGC parameter adjusting keys can adjust the currently displayed ultrasonic image, namely each TGC parameter adjusting key can adjust the currently displayed ultrasonic image, and a user can roughly determine the TGC parameter adjusting key corresponding to the image with the depth to be adjusted through visual inspection instead of blind attempt, so that the user operation is simplified.
In addition, when the currently displayed ultrasonic image is a partial image, all the TGC parameter adjustment keys are mapped to the currently displayed ultrasonic image, which means that the partial region of the currently displayed ultrasonic image is subdivided again, so that the adjustment accuracy is improved.
The following explains an implementation idea of the present application by taking an example of averagely dividing a currently displayed ultrasound image into N segments according to a first depth range.
Assuming that N is 8, that is, 8 TGC parameter adjustment keys are preset, and the depth range to which the currently displayed ultrasound image belongs is 0-12cm, the currently displayed ultrasound image is averagely divided into 8 segments of ultrasound images, and the depth ranges of the segments of ultrasound images are respectively: [0-1.5cm), [1.5cm-3cm), [3cm-4.5cm), [4.5cm-6cm), [6cm-7.5cm), [7.5cm-9cm), [9cm-10.5cm ], and [10.5cm-12 cm.
Assuming that the 8 TGC parameter adjustment keys are TGC1, TGC2, TGC3, TGC4, TGC5, TGC6, TGC7, and TGC8, respectively, the TGC parameter adjustment keys and the divided 8-segment ultrasound images can be associated as follows:
TGC1 corresponds to ultrasound images with a depth range of [0-1.5cm), TGC2 corresponds to ultrasound images with a depth range of [1.5cm-3cm), TGC3 corresponds to ultrasound images with a depth range of [3cm-4.5cm), TGC4 corresponds to ultrasound images with a depth range of [4.5cm-6cm), TGC5 corresponds to ultrasound images with a depth range of [6cm-7.5cm), TGC6 corresponds to ultrasound images with a depth range of [7.5cm-9cm), TGC7 corresponds to [9cm-10.5cm), and TGC8 corresponds to ultrasound images with a depth range of [10.5cm-12cm ].
Assuming that a user performs an enlarging operation on a currently displayed ultrasound image as required, and a depth range to which the currently displayed ultrasound image belongs after enlargement is 7cm-11cm, the ultrasound image in the depth range of 7cm-11cm is averagely divided into 8 sections of ultrasound images, and the depth ranges of the ultrasound images are respectively as follows: [7cm-7.5cm), [7.5cm-8cm), [8cm-8.5cm), [8.5cm-9cm), [9cm-9.5cm), [9.5cm-10cm), [10cm-10.5cm, [10.5cm-11cm ], then the following corresponding relations can be established between the 8 TGC parameter adjusting keys and the 8 ultrasound images obtained by division:
TGC1 corresponds to an ultrasound image with a depth range of [7cm-7.5cm), [7.5cm-8cm ] TGC2 corresponds to an ultrasound image with a depth range of [7.5cm-8cm ], TGC3 corresponds to an ultrasound image with a depth range of [8cm-8.5cm), [8.5cm-9cm ] TGC4 corresponds to an ultrasound image with a depth range of [8.5cm-9cm ], TGC5 corresponds to an ultrasound image with a depth range of [9cm-9.5cm ], TGC6 corresponds to an ultrasound image with a depth range of [9.5cm-10cm ], TGC7 corresponds to an ultrasound image with a depth range of [10cm-10.5cm ], and TGC8 corresponds to an ultrasound image with a depth range of [10.5cm-11cm ].
Assuming that the user performs a zoom-out operation on the currently displayed ultrasound image as required, and the depth range to which the currently displayed ultrasound image belongs after being zoomed out is 6cm-12cm, the ultrasound image in the depth range of 6cm-12cm is averagely divided into 8 segments of ultrasound images, and the depth ranges of the ultrasound images are respectively as follows: [6cm-6.75cm), [6.75cm-7.5cm), [7.5cm-8.25cm), [8.25cm-9cm), [9cm-9.75cm), [9.75cm-10.5cm), [10.5cm-11.25cm ], and [11.25cm-12cm ], the following correspondence relationship can be established between the 8 TGC parameter adjustment keys and the 8 ultrasound images obtained by dividing:
TGC1 corresponds to an ultrasound image with a depth range of [6cm-6.75cm), TGC2 corresponds to an ultrasound image with a depth range of [6.75cm-7.5cm), TGC3 corresponds to an ultrasound image with a depth range of [7.5cm-8.25cm), TGC4 corresponds to an ultrasound image with a depth range of [8.25cm-9cm), TGC5 corresponds to an ultrasound image with a depth range of [9cm-9.75cm), TGC6 corresponds to an ultrasound image with a depth range of [9.75cm-10.5cm), TGC7 corresponds to an ultrasound image with a depth range of [10.5cm-11.25cm), and TGC8 corresponds to an ultrasound image with a depth range of [11.25cm-12cm ].
In an optional embodiment, after a one-to-one correspondence relationship is established between preset N time gain compensation parameter adjustment keys and N divided ultrasound images, if an adjustment instruction of the time gain compensation parameter adjustment key (for convenience of description, recorded as a first time gain compensation parameter adjustment key) is received, a second depth range of the ultrasound image corresponding to the first time gain compensation parameter adjustment key is determined, and an ultrasound image in the second depth range is adjusted.
Wherein, the first time gain compensation parameter adjustment key is any one of the N time gain compensation parameter adjustment keys.
After the user operates the first time gain compensation parameter adjustment key, an adjustment instruction is generated, wherein the adjustment instruction carries the identification of the first time gain compensation parameter adjustment key and the adjustment amount of the time gain compensation parameter generated by the user operating the first time gain compensation parameter adjustment key.
And adjusting the ultrasound image belonging to the second depth range in the currently displayed ultrasound image according to the adjustment quantity of the time gain compensation parameter carried in the adjustment instruction so as to change the display effect of the ultrasound image belonging to the second depth range in the currently displayed ultrasound image.
How to adjust the image in the currently displayed ultrasound image that belongs to the second depth range can refer to the implementation manner in the prior art, and since it does not belong to the focus of the present application, it will not be described in detail here.
In an optional embodiment, before determining the first depth range to which the currently displayed ultrasound image belongs, the method may further include:
acquiring a mapping instruction;
in response to the mapping instructions, a first depth range to which the currently displayed ultrasound image belongs is determined.
In the embodiment of the present application, after the ultrasound image is zoomed in or zoomed out, the user may manually trigger the ultrasound image processing method provided by the present application to establish a mapping relationship between preset N time gain compensation parameter adjustment keys and N segments of ultrasound images in the currently displayed ultrasound image.
Manual operation makes the operation of user comparatively many, in order to further simplify user's operation, this application provides another implementation:
in an optional embodiment, before determining the first depth range to which the currently displayed ultrasound image belongs, the method may further include:
whether the ultrasonic image displayed by the ultrasonic imaging device is enlarged or reduced is monitored. The ultrasound image displayed by the ultrasound imaging device is enlarged or reduced, which includes two situations: the ultrasound image is entirely enlarged or reduced, or a part of the ultrasound image is enlarged or reduced.
When the fact that the ultrasonic image displayed by the ultrasonic imaging equipment is zoomed in or zoomed out is monitored, the image displayed after being zoomed in or zoomed out is determined to be the currently displayed ultrasonic image.
That is to say, in the embodiment of the present application, whether a user performs a zoom operation on an ultrasound image displayed by an ultrasound imaging device is monitored in real time, and when the user performs a zoom-in or zoom-out operation on the ultrasound image displayed by the ultrasound imaging device, an image displayed after being zoomed in or out (that is, a partial image of the ultrasound image in the maximum depth range scanned by the ultrasound imaging device) is determined as a currently displayed ultrasound image. Therefore, the mapping relation between the preset N time gain compensation parameter adjusting keys and the currently displayed N sections of ultrasonic images can be established in real time.
In an optional embodiment, before determining the first depth range to which the currently displayed ultrasound image belongs, the method may further include:
the region of interest of the ultrasound image displayed by the ultrasound imaging device is enlarged or reduced. The region of interest may be manually marked by a user.

That is, the currently displayed ultrasound image is a local zoom-in or zoom-out image, and after the region of interest is zoomed in or zoomed out, the ultrasound imaging apparatus displays the whole region of the region of interest, and may also display a partial region of the region of interest, so the local zoom-in or zoom-out image may be the whole region of the region of interest, and may also be the partial region of the region of interest.

In addition, when the currently displayed ultrasonic image is a partial image, all the TGC parameter adjustment keys are mapped to the currently displayed ultrasonic image, which means that the partial region of the currently displayed ultrasonic image is subdivided again, so that the adjustment accuracy is improved.
