The invention provides a portable three-dimensional ultrasonic imaging system, which comprises:
a case 101;
a housing 301 mounted in the case 101;
the B-ultrasonic module 403 is detachably placed in the storage device 301;
a three-dimensional space positioning module 402 detachably placed in the storage device 301;
an imaging calculation display module 401 detachably placed in the housing device 301;
the fixing device 201 is detachably placed in the accommodating device 301, and is used for installing the B-ultrasonic module 403, the three-dimensional space positioning module 402, and the imaging calculation display module 401 together with the case 101.
In this technical scheme, the box has open state and closed state, and when B-ultrasonic module, three-dimensional space orientation module, formation of image calculation display module and fixing device all place in the box, and the box is closed, the user can conveniently remove portable three-dimensional ultrasonic imaging system.
When the box body is in an open state, and the B-ultrasonic module, the three-dimensional space positioning module, the imaging calculation display module and the box body are installed together by adopting the fixing device, the portable three-dimensional ultrasonic imaging system can be started and used.
Specifically, the casing 101 includes a first casing 103 and a second casing 104 that is mounted on the first casing 103 in a reversible manner; the storage device 301 is mounted in the first casing 103. The opening and closing of the case 101 can be achieved by the relative overturning of the first case 103 and the second case 104.
Further, the housing device 301 is embedded in the case 101 and is made of a light material, and its internal shape is matched with the shape of each module and the corresponding fixing device. The modules and the corresponding fixing devices can be just arranged in the specific shapes when being retracted, so that the modules and the corresponding fixing devices can be safely stored in the box body.
Specifically, the storage device 301 is provided with a first accommodating groove 302 for storing an imaging calculation display module 401, a second accommodating groove 303 for storing a three-dimensional space positioning module 402 and a third accommodating groove 304 for storing a B-ultrasonic module 403;
the receiving device 301 has a first through hole 305 formed at the bottom of the first receiving groove 302, and the first through hole 305 and the first casing 103 enclose a fourth receiving groove for receiving the fixing device 201.
In this way, the first accommodating groove, the second accommodating groove, the third accommodating groove and the fourth accommodating groove are arranged to realize the accommodation of the fixing device, the B-ultrasonic module, the three-dimensional space positioning module and the imaging calculation display module; the fourth accommodating groove is formed through the first through hole and the first case, so that the space is utilized maximally.
Further, in use, the B-ultrasonic module 403, the three-dimensional space positioning module 402 and the imaging calculation display module 401 are connected in a wired or wireless communication manner, so as to cooperatively complete the function of three-dimensional ultrasonic imaging. In summary, an operator holds an ultrasonic probe of a B-ultrasonic module to scan an object of interest to obtain a real-time B-ultrasonic image, and simultaneously, a three-dimensional space positioning module obtains three-dimensional space information of the ultrasonic probe in real time, and transmits a series of B-ultrasonic images and corresponding three-dimensional space information to an imaging calculation display module in a wired or wireless manner to reconstruct, process and display a three-dimensional ultrasonic image. Three-dimensional ultrasound imaging methods using three-dimensional spatial localization are well known techniques and are therefore not described in detail herein.
Further, in the present embodiment, the case 101 is mounted with the roller 105 for convenience of movement. It will be appreciated that for cost savings, the case 101 may be a commercially available suitcase or travel case.
Further, a connection device 501 for fixing the tripod is provided on the outside of the case 101. By means of the connection means 501, the housing does not have to be particularly placed on a support having a certain height when the three-dimensional ultrasound imaging system is in use, but the height and/or angle of the housing can be adjusted by means of a tripod. This greatly increases the ease of use of the three-dimensional ultrasound imaging system. The housing may be secured to the ground or other surface, such as a table top, when the tripod is not mounted to the connection device.
Further, the portable three-dimensional ultrasound imaging system further includes a charging device 701 detachably disposed within the receiving device 301. The charging device 701 may be a wired or wireless charging device for charging the B-ultrasound module 403 and/or the three-dimensional spatial location module 402 and/or the imaging computing display module 401. Specifically, in the present embodiment, the storage device 301 has a second through hole 306 formed in the bottom of the third accommodation groove 304, and the second through hole 306 and the first casing 103 enclose a fifth accommodation groove for accommodating the charging device 701. The charging device 701 includes a battery for providing power and a plug or socket 801 electrically connected to the battery for charging the B-ultrasound module 403 and/or the three-dimensional spatial location module 402 and/or the imaging computation display module 401.
Further, in the present embodiment, the portable three-dimensional ultrasound imaging system further includes a magnetic connection device 203, and the three-dimensional space positioning module 402 and the imaging calculation display module 401 are connected to the fixing device 201 through the magnetic connection device 203, respectively. In this way, on the one hand, the portable three-dimensional ultrasound imaging system is firmly fixed in use, while the individual modules can be easily separated from their respective fixing means as and when required. This greatly increases the ease of operation of the three-dimensional ultrasound imaging system.
Further, the fixing device 201 includes a first fixing mechanism 204 and a second fixing mechanism 205; the magnetic connection device 203 comprises a first magnetic connection mechanism 206 and a second magnetic connection mechanism 207;
the imaging calculation display module 401 is connected with the first fixing mechanism 204 through the first magnetic force connecting mechanism 206; the three-dimensional space positioning module 402 is connected with the second fixing mechanism 205 through the second magnetic force connecting mechanism 207.
Specifically, the first fixing mechanism 204 includes a plurality of first connecting members 208, wherein two adjacent first connecting members 208 are rotatably connected. Similarly, the second securing mechanism 205 includes a plurality of second connecting members 209, wherein adjacent two second connecting members 209 are rotatably connected with respect to one another. The three-dimensional space positioning module, the imaging calculation display module and the fixing device can be further adjusted in all directions (namely, universally adjusted) through the first fixing mechanism 204 and the second fixing mechanism 205, so that the modules can be set to different heights and angles to facilitate ultrasonic scanning and operation. For example, the imaging calculation display module can adjust the height when displaying the scanning process, the result value and the image, so that the operator has the optimal height and angle, i.e. the display screen is adjusted at a certain height and angle, thereby being convenient for the operator. Further, the imaging calculation display module can be a tablet computer, a smart phone or a notebook computer, and the like, and a touch screen is adopted.
The B-ultrasound module 403 may further be a handheld wireless ultrasound probe with which ultrasound images are acquired and recorded. The wireless three-dimensional ultrasonic probe has special significance, and compared with wired equipment, the wireless three-dimensional ultrasonic probe can enable the whole three-dimensional ultrasonic scanning to be smoother.
Preferably, in the present embodiment, the B-ultrasonic module 403, the three-dimensional positioning module 402 and the imaging calculation display module 401 automatically adjust each module to a height and an angle preset by the ultrasonic scanning when the box 101 is opened, and are in an open operation state, and automatically stop operation when the box is closed. The height and angle preset for each module is adjusted by a resiliently compressible fixing means, i.e. the resiliently compressible fixing means is in a compressed state when the housing is in a closed state and stored together with the connected module in the receiving means 301.
When the case is opened, the resiliently compressible fastening means is automatically unfolded by means of the spring force so that the connected modules are moved to a predetermined height and angle. The elastic compressible fixing device provides a device which can enable the fixed device and the module to be automatically opened to enter an operating state when the box body is opened, such as a switch which can control the opening of the module, and the switch can be automatically set to be in an opened state when the box body is opened; the switch is automatically set to an off state when the housing is in an off state. The switch may be a magnetic switch. Thus, when the box body is opened, the three-dimensional ultrasonic imaging system can immediately enter a working state, as shown in fig. 8, then an operator 902 can detect the part to be detected of the scanned person by using the B-ultrasonic module 403, and three-dimensional ultrasonic imaging is realized by matching the three-dimensional space positioning module 402 with the imaging calculation display module 401, so that the convenience in use of the three-dimensional ultrasonic imaging system can be greatly improved.
The embodiments of the present invention have been described above with reference to the accompanying drawings, but the present invention is not limited to the above-described embodiments, which are merely illustrative and not restrictive, and many forms may be made by those having ordinary skill in the art without departing from the spirit of the present invention and the scope of the claims, which are to be protected by the present invention.
