Description

Ultrasonic scanning device, breast detection system, method, device and storage medium

Technical Field

The application relates to the field of breast imaging, in particular to ultrasonic scanning equipment, a breast detection system, a method, a device and a storage medium.

Background

Breast cancer is one of the more common cancers in women, and successful treatment and survival depends on early diagnosis. Breast cancer screening currently relies on mammography, three-dimensional mammography (also known as tomosynthesis) and ultrasound. Although tomosynthesis provides three-dimensional anatomical information of the breast, as with mammography, the breast is sandwiched between two plates, resulting in the breast not being in a natural state, and thus easily affecting the accuracy of the detection.

At present, some ultrasonic scanning imaging is performed by placing a patient in a prone position or a supine position, so that the patient needs to lie down or lie down, and the patient needs to lie down or lie down to adjust the position, which is not only troublesome for the patient, but also can influence the accuracy of breast detection due to the fact that the breast is not fixed and is easy to generate position variation, and in addition, the position adjustment process is time-consuming, so that the detection efficiency is low.

The following describes the technical scheme of the present application and how the technical scheme of the present application solves the above technical problems in detail with specific embodiments.

Referring to fig. 1, an embodiment of the present application provides an ultrasonic scanning apparatus including: a scan room 10, a milk film 20 and an ultrasound scanning assembly 30.

The scanning chamber 10 includes a housing 110 having a cavity inside, a first opening 111 is provided at a side of the housing 110, and the housing 110 is further provided with a first through hole 112 for liquid transfer.

Referring to fig. 1, the scan cell 10 has a barrel shape, and most of the side lying, the first opening 111 may have a diameter of 20 cm. Also, the scan cell 10 may take other shapes and be made of hard materials, such as polycarbonate or other hard plastic or metal materials, that are not easily broken under moderate pressure. The scan cell 10 is an airtight container, and the inner wall of the scan cell 10 may be coated with an ultrasonic wave absorbing material, which can suppress reflection of ultrasonic wave signals.

The milk film 20 is disposed at the first opening 111 and is a flexible film, and the milk film 20 is used to fit the breast and form a scanning cavity 210 with the inner wall of the housing 110.

Alternatively, the milk film 20 is made of a biocompatible and stretchable material such as silicone, rubber, latex or other biocompatible synthetic material capable of stretching under pressure.

Alternatively, a circular groove is provided around the first opening 111, and the edge of the milk film 20 may be a rigid edge or a stretchable flexible edge, and the edges of the stretchable milk film 20 of different sizes and depths may be tightly fitted into the groove.

Referring to fig. 1 and 2, the ultrasound scanning assembly 30 includes an ultrasound transducer array 310 positioned within the scanning cavity 210.

The ultrasonic scanning assembly 30 is configured to perform ultrasonic scanning on the breast of the target object through the ultrasonic transducer array 310 when the liquid enters the scanning cavity 210 through the first through hole 112 and the liquid level of the liquid reaches the first predetermined position when the breast is closely attached to the breast membrane 20; the first predetermined position is higher than the top of the milk film 20. The preferred liquid is water.

Alternatively, the target object is a patient in need of breast detection.

The side of the scanning chamber 10 of the ultrasonic scanning apparatus according to the embodiment of the present application is provided with the first opening 111, so that when a patient stands, the first opening 111 of the scanning chamber 10 can face the breast, the breast can be closely attached to the breast membrane 20, and when the liquid enters the scanning chamber 10 through the first through hole 112 and the liquid level of the liquid reaches the first predetermined position, the liquid overflows the top of the breast membrane 20 to cover the whole breast of the patient, so that the ultrasound can be transmitted through the liquid, and the breast can be scanned ultrasonically through the acoustic transducer array 310.

The breast of the ultrasonic scanning device is adhered to the flexible film, so that the problems of discomfort and deformation of the breast caused by clamping the breast between two plates in the prior art are avoided, and the accuracy of detection is improved. Moreover, the ultrasonic scanning equipment provided by the embodiment of the application can enable a patient to scan the breast in a standing position, so that the problem that the patient needs to lie down or lie down to adjust the position back and forth is avoided, the accuracy of breast detection is improved, the breast detection efficiency is improved, and the ultrasonic scanning equipment is simpler, more convenient and easier to operate and more comfortable.

The ultrasonic scanning equipment provided by the embodiment of the application is a method which is convenient for carrying out three-dimensional multi-mode tomographic ultrasonic imaging on the human breast of a patient based on standing posture, only one breast is imaged at a given time, and the scanning imaging is convenient.

In some embodiments, as shown in connection with fig. 1 and 2, the ultrasound scanning assembly 30 further comprises: a support structure 320 and a connecting shaft 330. Referring to fig. 2, an ultrasonic transducer array 310 is mounted on a support structure 320.

As shown in fig. 1 and 2, a first communication hole is formed in a side of the housing 110 opposite to the first opening 111, one end of the connection shaft 330 is fixedly connected to the support structure 320, and the other end passes through the first communication hole and is movable in an axial direction of the first communication hole or rotatable in the first communication hole.

In some embodiments, referring to fig. 1 and 2, a second communication aperture is provided in the connection shaft 330 for receiving a cable electrically connected to the ultrasonic transducer array 310.

In particular, the first opening 111 may allow a patient to rest on the opening, place her breast in the first opening 111, and allow the ultrasound transducer array 310 to move as close to the plane of the first opening 111 as possible in order to image the entire breast and portions of the chest wall.

Optionally, on the back of the housing 110 of the scan chamber 210, there is a first communication hole that allows the connection shaft 330 to pass through, and the connection shaft 330 is sealed watertight with an "O" shaped gasket.

Optionally, the connection shaft 330 drives the support structure 320 to move along the axial direction of the first communication hole or rotate in the first communication hole, so as to drive the ultrasonic transducer array 310 to move, thereby performing a movable full scan on the breast of the patient. The ultrasound transducer array 310 may also be moved without moving position to scan the entire breast.

In practice, for multi-modality 3D ultrasound imaging, one ring of ultrasound transducers around the breast, or one or more rows of ultrasound transducers rotating around the breast, is required.

In some embodiments, the ultrasound transducer array 310 comprises a plurality of ultrasound transducers arranged in at least one ring that encircles the periphery of the breast in a radial plane of the breast, the ultrasound transducer array 310 being configured for axial displacement from the first opening 111 to the first communication aperture to effect scanning of the breast.

The ultrasonic transducer array 310 of the embodiment of the present application performs the scanning of the breast by axially displacing the annular ultrasonic transducer array from the first opening 111 to the first communication hole.

Specifically, the breast is characterized by a sphere, and the central axis of the breast is characterized by an axis between the north and south poles of the sphere.

Alternatively, the ultrasound transducer may be arranged in a ring shape with a diameter slightly larger than the first opening 111 into which the breast enters. The support structure 320 may be a plurality of mechanical connection arms, the ring-shaped ultrasonic transducer may be mounted on each mechanical connection arm, and the other ends of all the mechanical connection arms are fixed on the connection shaft 330, and scanning may be achieved by driving the connection shaft 330 to displace the ultrasonic transducer array 310 from the first opening 111 toward the first communication hole, or displacing the ultrasonic transducer array from the first communication hole toward the first opening. The mechanical connection arms also serve as both physical support for the annular ultrasound transducer and as cable guides. All cable conduits converge into a second communication aperture inside the connecting shaft 330 through which the cable can pass through the appropriate seal to the outside of the scanning chamber 210.

As one example, referring to fig. 2, the ultrasound transducer array 310 includes ultrasound transducers arranged in at least two rows, each row surrounding the periphery of the breast with a different longitude; the ultrasound transducer array 310 is used to effect scanning of the breast by rotating at least two rows of ultrasound transducers.

In some embodiments, as shown with reference to fig. 2, every two rows of ultrasound transducers are arranged as a pair symmetrically with respect to the central axis of the breast.

Alternatively, the ultrasound transducers are arranged in at least two rows, and scanning of the breast is accomplished by rotating pairs of linear ultrasound transducer arrays along the front-to-back direction of the scan volume 210 as shown in FIG. 2. Two rows of ultrasonic transducers are placed on opposite sides of the imaging breast to form a pair, and multiple pairs can be used for accelerating the scanning speed, so that higher resolution is realized, and the problem of low resolution of high-density breast imaging is solved. The rows of ultrasound transducers may be mounted on mechanical connection arms, which also serve as both physical supports for the rows of ultrasound transducers and as cable guides. During imaging, the rows of ultrasound transducers are driven by the control unit 60 to rotate around the breast by the stretchable milk film 20. The connection shaft 330 is sealed watertight with an "O" shaped gasket, allowing the motor and gearbox to operate outside of the scan cavity 210.

In some embodiments, referring to fig. 1 and 2, the ultrasound scanning assembly 30 further comprises: a drive mechanism 100. The driving mechanism 100 is located outside the scan chamber 10, and the driving mechanism 100 is fixedly connected to one end of the connecting shaft 330 penetrating through the first communication hole, and is used for driving the connecting shaft 330 to move along the axial direction of the first communication hole or rotate in the first communication hole.

Alternatively, the drive mechanism 100 may be moved in translation outside the scan chamber 10 by a conventional linear motion (e.g., a linear drive or a ball screw).

Referring to fig. 1 and 2, the ultrasound scanning assembly 30 includes an ultrasound transducer array 310 positioned within a scanning cavity 210, a support structure 320 (e.g., a mechanical mount) that holds the ultrasound transducer array 310, and a connection shaft 330 that connects the support structure 320 and extends through the housing 110, and a drive mechanism 100 positioned outside the scanning cavity 210. The support structure 320 and the connection shaft 330 enable the mechanical drive mechanism 100 outside the scan cavity 210 to displace or rotate the ultrasound transducer array 310 within the scan cavity 210 while simultaneously drawing a cable connected to the ultrasound transducer array 310 out of the second communication aperture of the connection shaft 330. When liquid (water) enters the scanning cavity 210 through the first through hole 112 and the liquid level reaches a first preset position, a valve connected with a water path of the first through hole 112 is closed, the vacuum pump continues to pump air to enable the negative pressure of the scanning cavity 210 to reach a first preset air pressure, and at this time, the ultrasonic transducer array 310 is moved or rotated by the mechanical driving mechanism 100 outside the scanning cavity 210, so that the breast is scanned ultrasonically.

In some embodiments, as shown in connection with fig. 1 and 3, the housing 110 is provided with a ring of gaskets 220, the gaskets 220 surrounding the first openings 111.

In particular, the cushion 220 is used for both patient chest wall fitting and comfort, and may be an inflated plastic tube or a sealed foam material. The pad 220 may conform to the chest wall around the bottom of the breast, thereby forming an airtight seal that establishes a vacuum suction force on the water within the scan cavity 210 as air is drawn from the scan cavity 210. By the vacuum suction, breast tissue is pulled into the scanning cavity to the maximum extent under the premise of ensuring the comfort of a patient. By balancing the vacuum suction with the stretching force of the milk film 20, a positioning action is performed on the patient's breast, thereby maintaining its position and shape during scanning.

The pad 220 provides increased comfort to the woman when placing one of the two breasts within the milk film 20, against the scan cavity 210. When the patient rests at the first opening 111 of the scanning cavity 210, the breast is placed within the milk film 20, the surface of the pad 220 and the chest surface of the patient form an airtight coupling. Furthermore, the pad 220 may also be a part of the milk film 20, instead of being separately attached to the circumference of the first opening 111.

Alternatively, referring to fig. 3, the housing 110 is provided with a circle of clamping grooves around the first opening 111, and the gasket 220 is provided with a circle of clamping bars matched with the clamping grooves, and the clamping bars are clamped into the clamping grooves, so that the gasket 220 is mounted around the first opening 111.

In some embodiments, referring to fig. 1 and 2, the milk film 20 is cup-shaped, concave toward the direction of approaching the scanning chamber 210; the milk film 20 is provided with at least one slit which is closed when the air pressure in the scanning chamber 210 is atmospheric pressure, and which is opened after the air pressure in the scanning chamber 210 is reduced to a third preset air pressure, which is smaller than the atmospheric pressure.

The third preset air pressure is smaller than the atmospheric pressure, which indicates that the third preset air pressure is a negative pressure, and the slit can be opened only when the negative pressure in the scanning cavity 210 reaches a certain value (the third preset air pressure in the embodiment of the present application), that is, the slit is opened only when the negative pressure in the scanning cavity 210 is large enough. The main purpose of the slit is to absorb all the residual air between the breast membrane 20 and the breast before scanning, so that the flexible breast membrane 20 deforms with the breast and fits the breast, so that no gap exists between the breast membrane 20 and the breast, and attenuation of ultrasound during transmission in the air between the breast membrane 20 and the breast can be prevented. Moreover, the scan chamber 210 maintains a negative pressure that enables the breast to be placed against the breast membrane 20 such that the breast is substantially entirely within the housing 110 of the scan chamber 10 and stably positioned in a predetermined location in cooperation with the ultrasound scanning assembly 30, which is advantageous for improving the accuracy, reliability and stability of the ultrasound scan.

Optionally, after the air pressure in the scanning chamber 210 is reduced to the third preset air pressure belonging to the negative pressure, the air pressure control member 40 continues to pump out the air in the scanning chamber 210, and controls the air pressure in the scanning chamber 210 to reach (continue to be reduced to) the first preset air pressure. Alternatively, the third preset air pressure may be the same as the first preset air pressure.

Alternatively, the milk film 20 is shaped like a soft dome-shaped cup, resembling a die cup. Referring to fig. 3, the milk film 20 may be made in various sizes, and the edge of the milk film 20 is an annular edge which is pressed into the groove at the first opening.

In particular, the presence of the milk film 20 in a plurality of slits, which are air leakage holes, may allow any air between the milk film 20 and the imaging breast to be drawn into the scanning chamber 210 upon application of a substantial negative pressure. These gaps are normally closed and invisible when the milk film 20 is not under substantial negative pressure. The slit allows the flow of air or liquid to be unidirectional, i.e. only from the surface of the breast to the scanning chamber.

In some embodiments, referring to fig. 4, the ultrasound scanning apparatus further comprises: a pneumatic control 40.

The housing 110 is further provided with a first air hole 113, and the height of the first air hole 113 is higher than that of the first preset position;

The air pressure control member 40 is connected to the first air hole 113, and is configured to draw air in the scanning chamber 210 when the liquid is sucked into the scanning chamber 210 and the liquid level of the liquid reaches a first predetermined position, so that the air pressure in the scanning chamber 210 reaches a first preset air pressure.

Alternatively, the air pressure control member 40 is a vacuum pump, and the air in the scanning cavity 210 is pumped by the vacuum pump, so that a first preset air pressure is formed in the scanning cavity 210. The first preset air pressure is negative pressure, and the first preset air pressure can suck breast tissue of the target object into the scanning cavity 210 to the maximum extent, that is, the breast film 20 is recessed towards the direction close to the scanning cavity 210, so that the breast tissue of the target object can enter the first opening 111 as much as possible, and thus the breast tissue of the target object is sucked into the scanning chamber 10 to the maximum extent. The first preset air pressure is set based on maximum suction of breast tissue of the target subject into the scan cavity 210 without affecting the comfort of the target subject. The preset air pressure is about-150 mmHg and is far smaller than the atmospheric pressure.

Currently, since human breast tissue often extends laterally under the armpit, to ensure imaging of the entire breast tissue and a portion of the chest wall, a woman in the prone position is required to roll the body slightly, and in the prone position, it is also very difficult to control the degree of rolling.

Embodiments of the present application can place the breast in a standing position in a disposable, soft, stretchable milk film 20, imaging each of the two breasts at a time, the milk film 20 being tightly coupled to the scanning chamber 210. By resting against the scan cavity 210, the patient's chest wall and the first opening 111 form a tight seal, allowing negative pressure to be applied and breast tissue to be pulled into the scan chamber 10 for ultrasound scanning. The balance of the tensile force of the milk film 20 and the tensile force of the negative pressure realizes breast fixation in the scanning process, and improves the detection accuracy.

In some embodiments, referring to fig. 4, the ultrasound scanning apparatus further comprises: a liquid supply unit 50. The liquid supply unit 50 includes: a reservoir 510, a first communication tube 520, and a control valve 540; the two ends of the first communication pipe 520 are respectively connected with the liquid storage 510 and the first through hole 112, and the control valve 540 is arranged on the first communication pipe 520 and is used for controlling the connection or disconnection of the liquid storage 510 and the first through hole 112.

Optionally, the control valve 540 controls the opening or closing of the liquid reservoir 510 and the first through hole 112, so that the control valve 540 can be closed to maintain the negative pressure in the scanning cavity 210 when the liquid level of the liquid reaches the first predetermined position.

In some embodiments, as shown in connection with fig. 4 and 5, the ultrasound scanning apparatus further comprises: a control unit 60. The control unit 60 is electrically connected to the air pressure control member 40 and the control valve 540, where the control unit 60 is configured to control the control valve 540 to be opened, so that the liquid in the liquid storage 510 enters the scanning cavity 210 through conduction of the liquid storage 510 and the first through hole 112, and when the liquid level of the liquid reaches the first predetermined position, the control valve 540 is closed, so that after the liquid storage 510 and the first through hole 112 are closed, the air pressure in the scanning cavity 210 is controlled to reach the first preset air pressure through the air pressure control member 40.

In some embodiments, as shown in connection with fig. 4 and 5, the control unit 60 is further configured to control the air pressure control member 40 to pump the air in the scanning chamber 210 to the air pressure in the scanning chamber 210 reaching the second preset air pressure, so that the liquid is sucked into the scanning chamber 210.

Specifically, the second preset air pressure is used to make the liquid sucked into the scanning cavity 210, the air pressure control member 40 firstly pumps the air in the scanning cavity 210 to the air pressure in the scanning cavity 210 reaching the second preset air pressure, so that the liquid is sucked into the scanning cavity 210, after the liquid level of the liquid reaches the first preset position, the control unit closes the control valve 540 to stop the liquid reservoir 510 and the first through hole 112, and continues to pump the air in the scanning cavity 210, so that the air pressure in the scanning cavity 210 reaches the first preset air pressure. Alternatively, the first preset air pressure, the second preset air pressure and the atmospheric pressure are arranged from small to large.

Alternatively, the air pressure control member 40 may provide negative pressure to the scanning chamber 210, the control unit 60 opens the control valve 540, the reservoir 510 is communicated with the first through hole 112, the air pressure control member 40 starts to pump air, and water in the reservoir 510 is sucked into the scanning chamber 210. When the level of the liquid reaches the first predetermined position, the control valve 540 is closed, thereby closing the reservoir 510 and the first through hole 112. The air pressure control 40 continues to draw air out of the scan chamber 210 until the target negative pressure on the milk film 20 is reached, about-150 mmHg. At this time, the pressure of the top space of the scanning chamber 210 is higher than the pressure of the breast level, and the scanning is started after the scanning chamber 210 reaches a preset negative pressure.

Optionally, the control unit 60 is further configured to control the driving mechanism 100 to drive the ultrasound scanning assembly 30 to movably perform a full scan on the breast through the ultrasound transducer array 310 when the air pressure in the scanning cavity 210 reaches a first preset air pressure.

Specifically, the driving mechanism 100 drives the connection shaft 330 to move in the axial direction of the first communication hole or rotate within the first communication hole, so that the ultrasound transducer array 310 can movably perform an overall scan of the breast. For example, during imaging, the control unit 60 activates the drive mechanism 100 to perform a linear motion, slowly and controllably pulling the connection shaft 330 outward, moving the ultrasound transducer array 310 rearward from the forward-most position of the first opening 111. Wherein the anterior position is adjacent the chest wall of the patient and the posterior position is toward the breast.

In some embodiments, referring to fig. 4, the ultrasound scanning apparatus further comprises: a first sensor 70; the first sensor 70 is disposed on the inner wall of the housing 110, and the height of the first sensor 70 is not lower than the height of the top of the milk film 20.

The control unit 60 is electrically connected to the first sensor 70, and the control unit 60 is configured to determine a liquid level position of the liquid based on the first liquid level information output from the first sensor 70.

Alternatively, the first sensor 70 is a water level sensor, and may detect a liquid level position, and when the first sensor 70 detects that the liquid level reaches a first predetermined position, first liquid level information is sent to the control unit 60, so that the control unit 60 controls the control valve 540 to be closed.

Optionally, referring to fig. 4, the ultrasound scanning apparatus further includes: a second sensor 80; the second sensor 80 is disposed on an inner wall of the housing 110, and the second sensor 80 is disposed at a bottom of the housing 110.

The control unit 60 is electrically connected to the second sensor 80, and the control unit 60 is configured to determine that the liquid in the scanning chamber 210 has flowed out based on second liquid level information output by the second sensor 80, where the second liquid level information is sent when the second sensor 80 detects that the liquid level in the scanning chamber 210 is zero.

In some embodiments, referring to fig. 4, the liquid reservoir 510 includes a first liquid storage unit 511, a second liquid storage unit 512, and a filtering unit 513, the liquid supply unit 50 further includes a second communication pipe 530, a water pump 531, and the housing 110 is further provided with a second through hole 114.

The first liquid storage unit 511 is connected to the first through hole 112 through the first communication pipe 520; second reservoir unit 512 is connected to second port 114 through second communicating tube 530; the filtering unit 513 is disposed between the first liquid storage unit 511 and the second liquid storage unit 512, and the filtering unit 513 is configured to filter the liquid in the second liquid storage unit 512 and flow the filtered liquid into the first liquid storage unit 511.

Specifically, the filtering unit 513 may filter the water in the scanning chamber 210 and then return to the first liquid storage unit 511 for further recycling.

Alternatively, as shown in fig. 4, the first liquid storage unit 511 and the second liquid storage unit 512 are stacked, and the second liquid storage unit 512 is located above the first liquid storage unit 511. A water pump 531 is disposed in the second liquid storage unit 512. The control unit 60 is electrically connected to the water pump 531, and the control unit 60 is configured to start the water pump 531 to pump the liquid in the scanning cavity 210 back to the second liquid storage unit 512 when it is determined that the scanning of the breast in the scanning cavity is completed and the liquid in the scanning cavity 210 needs to be emptied.

In the embodiment of the application, the water pump 531 is adopted to pump the water back into the second liquid storage unit 512, so that the speed of returning the water to the second liquid storage unit 512 can be increased, and the filtered water and the unfiltered water are separated by the filtering unit 513, thereby realizing the recycling of the water and reducing the maintenance cost.

In some embodiments, referring to fig. 4, the reservoir 510 further includes a temperature control unit 514; the temperature control unit 514 is disposed in the first liquid storage unit 511, and is used for controlling the liquid in the first liquid storage unit 511 to maintain a preset temperature.

Specifically, the temperature control unit 514 may maintain the liquid at a preset temperature, so as to avoid the liquid from having too low a temperature, so that the liquid in the scanning cavity 210 has too low a temperature, which causes discomfort to the patient during detection and reduces the experience.

The ultrasonic scanning device according to the embodiment of the present application is a liquid supply unit 50 with filtering and heating functions, and after scanning, the liquid may naturally flow back to the second liquid storage unit 512, or may be pumped back to the second liquid storage unit 512 by a water pump 531, while maintaining a negative pressure in the scanning chamber 210 until the second sensor 80 at the bottom is triggered.

In some embodiments, referring to fig. 5, the ultrasound scanning apparatus further comprises: and a support assembly 90. The scan cell 10 is disposed on a support assembly 90, and the height of the support assembly 90 is adjustable.

Specifically, the scan room 10 is supported by a support assembly 90 that can raise or lower the height of the scan room 10 as needed to accommodate women of different heights.

Alternatively, the support assembly 90 is motorized, allowing the scan cell 10 to be raised or lowered by pressing a button.

In some embodiments, the scan cell 10 and the support assembly 90 are rotatably coupled for adjusting the angle between the central axis of the scan cell 10 and the horizontal.

Optionally, the first opening 111 of the scan chamber 10 is slightly upwardly inclined, with the first opening 111 being planar at about 75 degrees relative to the ground, to make it easier for the patient to place his or her breast into the first opening 111 and against it during imaging.

Alternatively, the scan room 10 may also be rotated to a small extent, allowing the first opening 111 to tilt more or less upwards to accommodate different patients.

Referring to fig. 6, a scenario is shown in which a patient is imaged in a standing position while resting in a scan room. As shown in fig. 4 to 6, in practical application, the procedure of ultrasound scanning of the breast is as follows:

a thin layer of ultrasound coupling gel is spread onto the skin of the breast, with no water in the scanning chamber 210. A milk film 20 suitable for imaging the breast size is selected and mounted at the first opening 111. The height of the scan room 10 is adjusted according to the height of the patient's breast. The torso of the patient is correctly tilted to maximize placement of all breast tissue into the scan room 10. The patient then places the breast in the milk film 20 and tilts forward onto the scan room 10, thereby establishing an airtight seal between the pad 220 around the first opening 111 of the scan room 10 and the skin surface around the patient's breast.

After the patient places the breast within the milk membrane 20, the operator initiates the ultrasound imaging procedure at the control interface of the control unit 60 using user input (e.g., a button or physical actuation button on the control interface screen). Once activated, the vacuum pump will operate to draw air from the scan chamber 10, and the control valve 540 opens to allow water to be drawn into the scan chamber 10 from the first reservoir 511, while the vacuum pump continues to pump air out of the scan chamber 10. When the water rises to the first sensor 70 near the top of the scan chamber 10, the control unit 60 will close the control valve 540 and the vacuum pump will continue to operate until a first preset air pressure is reached, and then automatically maintain the first preset air pressure.

At a first preset pressure, breast tissue is pulled into the scan chamber 10. The slit in the wall of the milk film 20 will ensure that no air is present between the breast skin and the milk film 20 to achieve a perfect ultrasound scan. At this time, the tensile force of the first preset air pressure and the stretching action of the milk film 20 are balanced in the scanning chamber 10, so as to realize the reliable fixation of the breast. The buoyancy of the water also prevents the breast from falling under gravity so that all tissue of the breast can be imaged for easier full scan detection of the breast.

The scan cell 10 reaches a first preset air pressure and the control unit 60 will initiate the scan procedure. After the scanning is completed, the control unit 60 controls the water pump 531 to pump water from the scanning chamber 10 back to the second liquid storage unit 512 while maintaining the negative pressure in the scanning chamber 10.

At this point, the vacuum pump will act as a controllable relief valve, not allowing the negative pressure in the scanning chamber 10 to drop to ambient pressure, so that the water within the scanning chamber 10 will not exert pressure on the breast. The detection of the scan room 10 being empty by the second sensor 80 indicates that the patient has moved his breast out of the scan room 10. The ultrasound scanning apparatus is ready to image another breast or breast of another patient.

Based on the technical scheme, the ultrasonic scanning equipment provided by the embodiment of the application is used for carrying out automatic multi-mode tomographic ultrasonic imaging on the breast of the human body by a patient in a basic standing posture. In order to image the breast being imaged in a more natural three-dimensional shape, a thin layer of coupling gel is applied uniformly over the imaged breast, placed in the milk film 20, and held tightly against the first opening 111 of the airtight scan chamber 10. An ultrasound scanning assembly 30 within the hermetically sealed and rigid scan chamber 10 can enable 3D scanning of the breast. During the imaging process, the scanning chamber 10 is filled with water, and is sucked from the first liquid storage unit 511 through the first through hole 112. Negative pressure is applied to the water between the milk film 20 and the housing 110. The negative pressure helps pull breast tissue into the imaging volume and the milk film 20 can hold and secure the breast in a more natural three-dimensional shape.

While maintaining the first preset air pressure, the control unit 60 will initiate a scanning procedure by instructing the drive mechanism 100 to move the ultrasound transducer array 310 and for subsequently instructing the data acquisition unit 300 to determine transmission, reflection and propagation times based on the transmitted and received ultrasound signals of the ultrasound transducer array 310. After the scan is completed, water is pumped back into the second reservoir 512 and negative pressure is maintained. After the scan cell 10 is emptied, the negative pressure will be turned off. The patient removes the breast from the milk film 20.

The ultrasonic scanning apparatus of the embodiment of the present application generates negative pressure by using the scanning chamber 10 with the inlet and outlet holes, the stretchable membrane 20 and the pneumatic control 40, and the patient can image the breast in a standing posture and can place all breast tissues in the imaging space with the correct body rotation angle. Compared with the traditional prone arrangement, the ultrasonic scanning device of the embodiment of the application is easier and more comfortable for a patient, thereby accelerating the imaging process and simultaneously realizing that more breast tissues can be imaged in an imaging space.

Based on the same inventive concept, as shown in fig. 7 and 8, an embodiment of the present application provides a breast detection system, including: at least one biopsy port 200 for access by a biopsy needle 230 and an ultrasound scanning device of an embodiment of the present application.

Referring to fig. 7, the housing 110 is provided with at least one third through hole 115, and each biopsy port 200 is correspondingly installed at one third through hole 115.

In some embodiments, referring to fig. 7, biopsy port 200 is removably coupled to third through bore 115 and is airtight.

Alternatively, the biopsy port 200 is a screw-in plug comprising a connecting portion with a through hole therein, the outer surface of the connecting portion being provided with a threaded section, and an outer rim portion extending radially outwardly of the connecting portion. The connecting portion comprises a first section and a second section, the outer surface of the first section is a threaded section, the cross section of the second section is an inclined plane, and two ends of the second section are respectively connected with one end of the first section and one end of the outer edge portion. The second section forms a flared opening in the side of the first section remote from the housing 110.

Optionally, as shown in fig. 7, a gasket 220 is provided between the biopsy port 200 and the housing 110. Gasket 220 is an "O" ring seal. Specifically, the gasket 220 is provided between the outer edge portion and the housing 110.

In some embodiments, referring to fig. 8, a schematic diagram of an ultrasound scanning device with a biopsy port 200 and a biopsy needle 230 inserted into the biopsy port 200 is shown. The third through hole 115 is located above the central axis of the housing 110 and at both sides thereof.

In some embodiments, referring to fig. 7, biopsy port 200 is filled with a rubber filler 210 for repeated penetration by biopsy needle 230 without leakage. The rubber packing 210 is a disc-shaped rubber pad.

In practice, biopsy needle 230 may pierce soft rubber fill 210 without breaking the vacuum when biopsy needle 230 is retracted. While repeated puncturing of a single biopsy port 200 may impair the water tightness of the biopsy port 200, breast detection systems of embodiments of the present application may require replacement of only the biopsy port 200 for plug replacement, without replacement of the scan cavity 210.

Embodiments of the present application provide a plurality of biopsy ports 200 in housing 110, these biopsy ports 200 being points through which biopsy needle 230 may penetrate without breaking vacuum. The rubber filler 210 may be implemented by injecting and filling the through hole in the biopsy port 200 with a soft biocompatible plastic material. However, repeated insertion of biopsy needle 230 may result in biopsy port 200 being breathable, and thus biopsy port 200 of embodiments of the present application may be removable and replaceable.

In some embodiments, referring to fig. 5, the breast detection system further comprises: a data acquisition unit 300; the data acquisition unit 300 is electrically connected with the ultrasonic transducer array 310 and is used for acquiring a reflected signal, a transmitted signal and a propagation time from the ultrasonic transducer array 310; the transmission signal is a signal received by the opposite ultrasonic transducer after the ultrasonic signal transmitted by the ultrasonic transducer array 310 is transmitted through the breast, the reflection signal is a signal received by the ultrasonic transducer array 310 after the ultrasonic signal is transmitted and reflected by the breast tissue with different depths, and the propagation time is the time difference between the transmission signal and the reception signal.

Specifically, the transmission signal is a signal that is received by the transducer of the ultrasonic transducer array 310 by the transducer opposite the breast, and the reflection signal is a signal that is received by the transducer of the ultrasonic transducer array 310 by the transducer after being reflected by the breast tissue at different depths of the breast, and the propagation time is a time difference between the ultrasonic signal transmitted by the transducer on one side of the breast and the transmission signal received by the transducer opposite the breast.

In some embodiments, referring to fig. 5, the breast detection system further comprises: a processing unit 400; the processing unit 400 is electrically connected to the data acquisition unit 300, and is configured to determine a three-dimensional reflected image, a three-dimensional transmitted image, and a three-dimensional sound velocity image according to the reflected signal, the transmitted signal, and the propagation time of the ultrasonic transducer array 310, respectively, using a predetermined image reconstruction algorithm. Unlike conventional ultrasound imaging, multimode ultrasound tomograms can be scanned from a single scan to obtain three-dimensional images, each reflecting different physical and biological characteristics of the breast, thus obtaining more information.

The image reconstruction algorithm run in the processing unit 400 creates three-dimensional images from three different signals, including a three-dimensional reflected image, a three-dimensional transmitted image, and a three-dimensional sonic image. The three-dimensional images are calculated by using mature image reconstruction algorithms, including a back projection algorithm, a numerical iteration algorithm and the like.

The processing unit 400 executes image reconstruction software and calculates tomographic pixel values, including reflected signals, transmitted signals, and travel times, from the data acquired in the different modes. After the images are constructed, they will be displayed on the display unit 500 and saved under the personal information of the patient. Meanwhile, the embodiment of the application can use artificial intelligent software to carry out local analysis, can also input other computer software to carry out automatic diagnosis or screening, and can also use an international standard format and a commonly accepted communication protocol to send to a medical care provider or other related parties or systems.

The processing unit 400 may be a CPU (Central Processing Unit ), general purpose processor, DSP (Digital Signal Processor, data signal processor), ASIC (Application Specific Integrated Circuit ), FPGA (Field Programmable Gate Array, field programmable gate array) or other programmable logic device, transistor logic device, hardware components, or any combination thereof. Which may implement or perform the various exemplary logic blocks, modules and circuits described in connection with this disclosure. The processing unit 400 may also be a combination implementing computing functionality, e.g., comprising one or more microprocessor combinations, a combination of a DSP and a microprocessor, etc.

In some embodiments, the processing unit 400 is further configured to determine a biopsy region from the three-dimensional reflected image, the three-dimensional transmitted image, and the three-dimensional sound velocity image of the breast, and to determine the biopsy port 200 from the biopsy region.

According to the embodiment of the application, at least one biopsy port 200 is arranged, and a proper biopsy port 200 can be correspondingly selected for insertion according to the position of a biopsy area, so that biopsy operation is facilitated, and biopsy efficiency is improved.

In some embodiments, referring to fig. 5, the breast detection system further comprises: a display unit 500; the display unit 500 is electrically connected with the processing unit 400, and the display unit 500 is used for acquiring and displaying a real-time three-dimensional scanning image of the breast when the biopsy needle 230 is inserted into the biopsy port 200 and moved toward the biopsy region; the real-time three-dimensional scan image includes a three-dimensional reflection image, a three-dimensional transmission image, and a three-dimensional sound velocity image.

Optionally, the ultrasound transducer array 310 includes a plurality of ultrasound transducers arranged in at least one ring, which can be performed at the same time period as the scanning imaging and the needle biopsy of the biopsy needle 230. The needle biopsy of the ultrasound transducer array 310 and the biopsy needle 230 may also not be performed at the same time period, e.g. the ultrasound transducer array 310 comprises ultrasound transducers arranged in at least two rows.

A three-dimensional scan image of the breast of an embodiment of the present application is reconstructed and if the operator or computer notices a suspicious abnormality through deep learning artificial intelligence, a biopsy region is determined and the system will prompt the user to take a biopsy from the selected biopsy port 200. The selection of the selected biopsy port 200 is based on two factors: 1) The most convenient and shortest path through breast tissue; 2) The direction of imaging is not disturbed, i.e. the ultrasound transducer is allowed to continue imaging the suspicious region while the biopsy needle 230 is inserted, so that the breast detection system can verify in real time whether the correct tissue is being collected.

The processing unit 400 of an embodiment of the present application may determine the longitudinal and latitudes of the biopsy region, insert the biopsy needle 230 to a specified longitudinal and latitudes using the selected biopsy port 200, and the operator may sample the biopsy needle 230 in alignment with the suspicious region in the breast, or may sample automatically using the biopsy needle 230. Upon insertion of the biopsy needle 230, the display unit 500 will display a real time three-dimensional scan image so that an operator can see the insertion of the biopsy needle 230 into the biopsy region or adjust the position of the biopsy needle 230 into the biopsy region. Therefore, the breast detection system provided by the embodiment of the application can carry out biopsy on the suspected region in the breast under the guidance of an ultrasonic image.

Based on the same inventive concept, the embodiment of the present application further provides an ultrasonic scanning method, which is applied to the ultrasonic scanning apparatus of the embodiment of the present application, and as shown in fig. 9, the ultrasonic scanning method includes:

s901, when the breast of the target object is closely attached to the breast membrane 20, controlling the liquid to enter the scanning cavity 210 through the first through hole 112.

S902, when the liquid level of the liquid reaches the first predetermined position, the air pressure control member 40 of the ultrasonic scanning device is used to pump air from the scanning cavity 210, so that the air pressure in the scanning cavity 210 reaches the first predetermined air pressure, and the ultrasonic transducer array 310 is controlled to perform ultrasonic scanning on the breast.

Specifically, the first preset air pressure is used to suck breast tissue of the target object into the scanning chamber 210 to the maximum extent, that is, the milk film 20 is recessed toward the direction approaching the scanning chamber 210, so that the breast tissue of the target object can enter the first opening 111 as much as possible, thereby sucking the breast tissue of the target object into the scanning chamber 10 to the maximum extent. The first preset air pressure is set based on maximum suction of breast tissue of the target subject into the scan cavity 210 without affecting the comfort of the target subject. The ultrasonic scanning method of the embodiment of the application can play a role in positioning the breast of a patient through the balance of vacuum suction and the stretching force of the milk film 20, so that the position and the shape of the breast can be maintained during scanning.

The ultrasonic scanning method of the embodiment of the application is applied to the ultrasonic scanning equipment of the embodiment of the application, and the breast is adhered to the flexible film, so that the problems of discomfort caused by clamping the breast between two plates and deformation on the breast in the prior art are avoided, and the accuracy of detection is improved. Moreover, the ultrasonic scanning method provided by the embodiment of the application can enable a patient to scan the breast in a standing position, so that the problem that the patient needs to lie down or lie down to adjust the position back and forth is avoided, the accuracy of breast detection is improved, the breast detection efficiency is improved, and the method is simpler, more convenient and more comfortable to operate.

The ultrasonic scanning method of the embodiment of the application is a method which is convenient for carrying out three-dimensional multi-mode tomographic ultrasonic imaging on the human breast of a patient based on standing posture, and only one breast is imaged at a given time, so that the scanning imaging is convenient.

Embodiments of the present application can place the breasts in a standing position in a disposable, flexible, stretchable milk film 20, imaging each of the two breasts at a time, the milk film 20 being tightly coupled to the scan cavity 210. By resting against the scan cavity 210, the patient's chest wall and the first opening 111 form a tight seal, allowing negative pressure to be applied and breast tissue to be pulled into the scan chamber 10 for ultrasound scanning. The balance of the tensile force of the milk film 20 and the tensile force of the negative pressure realizes breast fixation in the scanning process, and improves the detection accuracy.

Optionally, controlling the ultrasound transducer array 310 to ultrasonically scan the breast includes: the support structure 320 is controlled to move axially along or rotate within the first communication hole of the connection shaft 330, so as to drive the ultrasonic transducer array 310 to perform ultrasonic scanning on the breast.

Optionally, when the breast of the target subject is in close proximity to the milk film 20, controlling the liquid to enter the scanning chamber 210 through the first through hole 112 includes: the control air pressure control member 40 draws out air in the scanning chamber 210 and controls the control valve 540 of the liquid supply unit 50 to be opened, so that the liquid reservoir 510 and the first through hole 112 of the liquid supply unit 50 are communicated to suck liquid into the scanning chamber 10;

when the liquid level of the liquid reaches the first preset position, the air pressure in the scanning cavity 210 reaches the preset air pressure by pumping the air pressure control part 40 of the ultrasonic scanning device to pump the scanning cavity 210, which comprises the following steps: when the liquid level of the liquid reaches the first predetermined position, the control valve 540 is closed to stop the liquid reservoir 510 and the first through hole 112, and the scanning cavity 210 is pumped by the air pressure control member 40 of the ultrasonic scanning device, so that the air pressure in the scanning cavity 210 reaches the preset air pressure.

Optionally, in step S902, after controlling the ultrasound transducer array 310 to perform ultrasound scanning on the breast when the liquid level of the liquid reaches the first predetermined position, the method includes:

The second liquid storage unit 512 of the control liquid storage 510 is communicated with the second through hole 114 of the shell 110 to return the liquid to the second liquid storage unit 512;
