Example 1
The present embodiments provide an imageable system for displaying three-dimensional images of a predetermined site in a body. Such as the fossa ovalis, atria, etc., in the body.
As shown in fig. 1, the imageable system includes a power module 107, the power module 107 providing power to the imageable system, and further includes a signal transmitter 101, a signal sensor 103, a signal processing unit 104, and a display control unit 105. The signal processing unit 104 and the signal sensor 103 may enable efficient transfer of information, such as through wired or wireless access. Where a and B access may refer to a and B coupling, and thus information exchange occurs between a and B.
When three-dimensional development is needed in vivo, the signal transmitter 101 is conveyed to a first preset position of a preset part, and when the signal transmitter 101 is at the first preset position, imaging source signals can be sent to the periphery uninterruptedly. The first preset position can be reasonably selected by those skilled in the art according to clinical practical situations, and the signal emitter 101 can be fixed or moved as required during the process of sending the imaging source signal by the signal emitter 101. In some embodiments, the signal transmitter 101 may also transmit signals at a fixed frequency.

The signal sensor 103 may be integrated with the signal emitter 101 in a single unit device to be delivered to a first predetermined location at a predetermined location in the body, or may be a separate device to be delivered to the predetermined location in the body.

As shown in fig. 2, the display control unit 105 includes a display 1051 and a control layer 1052, and the control layer 1052 can perform operation control on the imageable system, such as adjustment of signal frequency of the signal transmitter 101, modification of the distance display preset point, and the like. The display control unit 105 receives the three-dimensional data analyzed by the signal processing unit 104, generates a three-dimensional image according to the three-dimensional data, and displays the three-dimensional image of the preset portion on the display 1051. The operator can clearly observe the spatial information of the preset portion in the body by observing the display 1051.
In the above embodiment, the signal transmitter 101 transmits a signal at a first preset position of the preset portion, so that the spatial environment of the preset portion can be sensed in real time. After receiving a signal returned by encountering an obstacle, the signal sensor 103 converts the returned signal into an imageable signal, and transmits the imageable signal to the signal processing unit 104, the signal processing unit 104 analyzes the imageable signal to obtain three-dimensional data of a preset part, and transmits the three-dimensional data to the display control unit 105, the display control unit 105 expresses a three-dimensional image of the preset part according to the three-dimensional data, so that the preset part is dynamically displayed in real time, and the display control unit 105 can perform artificial parameter adjustment intervention on an imaging source signal transmitted by the signal transmitter 101 according to the fed-back signal and the three-dimensional image to achieve an ideal imaging effect.
The imaging system provided by the embodiment is clearer than a three-dimensional image formed by using a section scanning device in modes such as in-vitro scanning and the like, is higher in accuracy, can dynamically monitor the preset part in real time, and can timely know when the environment of the preset part in vivo changes.
As shown in fig. 1, the signal receiver 102 is connected to the signal sensor 103, and after receiving a signal returned by an obstacle, the signal receiver 102 can perform appropriate amplification according to the received signal strength, transmit the amplified signal to the signal sensor 103, and convert the returned signal into an imageable signal by the signal sensor 103. If the receiver 102 is not provided, the signal sensor 103 should be provided with a signal receiving device in order to receive a signal returned when an obstacle is encountered.
The signal transmitter 101 and the signal receiver 102 may be integrated into a single signal source unit, i.e. the signal transmitter 101 and the signal receiver 102 are delivered as a whole to a predetermined location in the body. The signal transmitter 101, signal receiver 102 and signal sensor 103 may also be integrated into a signal sensing unit that is delivered to a predetermined location in the body.
The signal receiver 102 and the signal sensor 103 are connected, and can perform moderate amplification according to the intensity of the signal returned by encountering an obstacle, so as to ensure the definition and accuracy of the finally displayed three-dimensional image. In some embodiments, the signal transmitter 101, the signal receiver 102 and the signal sensor 103 may be integrated into a single signal sensing unit, which performs the transmission and return reception of the imaging source signal and performs the preprocessing conversion.
