  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described with reference to the drawings.

  1 and 2 are views for explaining a preferred embodiment of a wireless ultrasonic diagnostic apparatus according to the present invention. The wireless ultrasonic diagnostic apparatus according to this embodiment includes an ultrasonic probe and an apparatus main body. FIG. 1 shows a functional block diagram of the ultrasonic probe, and FIG. 2 shows a function of the apparatus main body. A block diagram is shown.

  As shown in FIG. 1, the ultrasonic probe includes a plurality of transducers 102 that transmit and receive ultrasonic waves to and from a subject. An ultrasonic transmission circuit (not shown) is connected to each transducer 102, and ultrasonic pulses are transmitted from the plurality of transducers 102 toward the subject in accordance with signals output from the transmission circuit. The Then, a plurality of transducers 102 receive reflected waves (echoes) obtained from the subject.

  An amplifier 104 and an analog-digital converter (ADC) 106 are provided corresponding to each of the plurality of vibrators 102. Each amplifier 104 amplifies the reception result of the corresponding transducer 102 and outputs it to the corresponding ADC 106. As a result, the received signal obtained from each transducer 102 is digitized and output from the plurality of ADCs 106 to the digital beam former 108.

  The digital beam former 108 is a circuit that performs reception beam forming by phasing and adding reception data (digitized reception signals) obtained from a plurality of ADCs 106. In the present embodiment, the digital beam former 108 performs a first-stage phasing addition process. That is, for a plurality of transducers 102, for example, 64 transducers 102, the phasing addition processing is performed for each transducer group including eight adjacent transducers 102. Then, phasing addition processing is performed for each of the eight transducer groups, and the phasing addition result of each transducer group is set as one channel, and phasing addition data of a total of eight channels is output from the eight transducer groups.

  Incidentally, the second-stage phasing addition processing is performed in the digital beamformer (reference numeral 218 in FIG. 2) in the apparatus main body, which will be described later, and the received data obtained from all the transducers 102 is one beam data. It is summarized as.

  The PS conversion unit 110 receives the 8-channel phasing addition data formed in the digital beamformer 108 as parallel data, and converts the received 8-channel parallel data into serial data arranged in a line in the time axis direction. Then, the phasing addition data for eight channels converted into the serial data is output to the modulator 122.

  The digital beam former 108 performs phasing addition processing on the reception data output one after another for each reception beam. Therefore, the phasing addition results for the plurality of reception beams are output one after another from the digital beam former 108, and the phasing addition data for the plurality of reception beams are output one after another in time series from the PS conversion unit 110. Therefore, synchronization data of each reception beam is inserted into a series of serial data output from the PS conversion unit 110, and a break for each reception beam is provided in the serial data. Also, information such as probe setting data may be inserted into the serial data output from the PS conversion unit 110 in addition to the phasing addition result of the reception data and the synchronization data of the reception beam.

  The modulator 122 performs digital modulation processing such as PSK (Phase Shift Keying) based on the serial data output from the PS converter 110. Instead of PSK, digital modulation processing such as ASK (Amplitude Shift Keying) and FSK (Frequency Shift Keying) may be used. Then, the modulated signal modulated by the modulator 122 is power amplified by the power amplifier 124 and transmitted from the transmission antenna 126 as a radio signal. The transmission antenna 126 is a planar antenna, for example.

  In this way, the radio signal modulated by the digital echo signal collected in one channel is transmitted. For example, a one-channel radio signal having a transmission carrier frequency of 60 GHz and a band of about 1 GHz is transmitted.

  A radio signal transmitted from the ultrasonic probe via the antenna is received by the receiving antenna 202 of the apparatus main body shown in FIG. 2, and is amplified by the power amplifier 204 via the preamplifier 203 and then to the demodulator 206. Sent. Demodulator 206 performs demodulation processing on the radio signal that has been subjected to digital modulation processing such as PSK, and outputs the demodulated digital signal to waveform reproduction circuit 208. Thereby, the data before being modulated by the modulator of the ultrasonic probe (reference numeral 122 in FIG. 1), that is, the data corresponding to the serial data output from the PS converter (reference numeral 110 in FIG. 1) is converted into the waveform reproduction circuit 208. Is played.

  Data reproduced by the waveform reproduction circuit 208, that is, serial data including a phasing addition result of the received data is output to the frame synchronization detection circuit 210 and the like. The frame synchronization detection circuit 210 detects a frame synchronization signal included in the serial data.

  The SP converter 214 converts the 8-channel phasing addition data included in the serial data output from the waveform reproduction circuit 208 into parallel data. At this time, the data is converted into 8-channel parallel data based on the frame synchronization signal detected by the frame synchronization detection circuit 210.

  Thus, parallel data corresponding to the data formed by the digital beamformer (108 in FIG. 1) of the ultrasonic probe is stored in the memory 216. The data stored in the memory 216 is read at a timing corresponding to the subsequent processing of the memory 216. As the memory 216, for example, a first input first output (FIFO) type device is used.

  The digital beamformer 218 reads the parallel data stored in the memory 216 and executes a second-stage phasing addition process. That is, the parallel data corresponding to the data formed by the digital beamformer (reference numeral 108 in FIG. 1) is read from the memory 216, and the phasing addition processing is executed based on the read parallel data for eight channels, and all vibrations are obtained. Received data obtained from the child is collected to form one beam data. The beam data is sequentially formed for each reception beam and output to the image forming unit 220.

  The image forming unit 220 forms image data of ultrasonic images such as a B-mode image, an M-mode image, and a Doppler image based on beam data that is sequentially formed for each reception beam. Then, an ultrasonic image corresponding to the formed image data is displayed on the monitor 222.

  The serial data reproduced by the waveform reproduction circuit 208 is also output to the probe setting data recognition circuit 212. The probe setting data recognition circuit 212 reads the probe setting data included in the serial data, and confirms the setting state of the ultrasonic probe (FIG. 1). For example, the diagnostic mode set on the ultrasonic probe side is confirmed, and the diagnostic mode information is output to the image forming unit 220. Then, the image forming unit 220 forms image data by executing an image forming process corresponding to a diagnostic mode set on the ultrasonic probe side, that is, an image forming process of a B-mode image, an M-mode image, or a Doppler image. Further, a display mode indicating the setting state on the ultrasonic probe side may be displayed in the ultrasonic image.

  The image signal forming unit 230 forms an image signal based on the image data of the ultrasonic image formed by the image forming unit 220. That is, based on the image data, an image signal (video signal) for transmitting an ultrasonic image of the image data is formed. The image signal is, for example, a television video signal (NTSC system or the like) configured by a synchronization signal, a luminance signal, or the like.

  The modulator 232 uses the image signal output from the image signal forming unit 230 as a modulation signal, and performs modulation processing on the wireless carrier wave. For example, an amplitude modulation process is performed on the image signal. The modulated radio signal modulated by the modulator 232 is amplified by the power amplifier 234 and transmitted from the transmission antenna 236 as a radio signal.

  A radio signal transmitted as a radio signal from the apparatus main body is received by the receiving antenna 130 of the ultrasonic probe shown in FIG. 1, and is amplified by the power amplifier 132 via the preamplifier 131 and then to the demodulator 134. Sent. The demodulator 134 demodulates the image signal with respect to the radio signal that has been subjected to modulation processing such as amplitude modulation, and outputs the image signal to the display image processing unit 136.

  Then, the display image processing unit 136 forms a display image using the image signal transmitted from the apparatus main body, and the formed display image is displayed on the monitor 138. As a result, a display image corresponding to the ultrasonic image displayed on the monitor (reference numeral 222 in FIG. 2) of the apparatus main body is displayed on the monitor 138 of the ultrasonic probe.

  FIG. 3 is a diagram for explaining another preferred embodiment of the wireless ultrasonic diagnostic apparatus according to the present invention, and FIG. 3 shows a functional block diagram of a separation-type ultrasonic probe. The ultrasonic probe of FIG. 3 is used in combination with the apparatus main body of FIG. That is, the ultrasonic probe in FIG. 3 corresponds to a modified embodiment of the ultrasonic probe in FIG. Of the functions in the ultrasonic probe of FIG. 3, the same parts as those of the ultrasonic probe of FIG. Therefore, the functions of the same reference numerals as those shown in FIG. 1 are simplified and the functions of the ultrasonic probe of FIG. 3 will be described.

  In the embodiment shown in FIG. 3, the ultrasonic probe includes a probe main body 100 and a separation unit 120.

  The probe main body 100 includes a plurality of transducers 102, a transmission circuit corresponding to each transducer 102, an amplifier 104, and an analog-digital converter (ADC) 106. Then, the digital beam former 108 performs a first-stage phasing addition process on the reception data obtained from the plurality of ADCs 106.

  The PS conversion unit 110 receives the phasing addition data formed in the digital beam former 108 as parallel data, and converts the received parallel data into serial data arranged in a line in the time axis direction. Then, the phasing addition data converted into the serial data is output to the cable 114 via the cable driving circuit 112. In the cable driving circuit 112, a power amplifier, a buffer, and the like for transmitting a signal to the cable 114 are provided.

  Thus, serial data including the phasing addition result of the received data is output from the probe main body 100 via the cable 114.

  The separation unit 120 transmits serial data supplied from the probe main body 100 to the apparatus main body (FIG. 2) as a radio signal. The modulator 122 performs digital modulation processing such as PSK based on serial data supplied via the cable 114. Then, the signal modulated by the digital signal in the modulator 122 is amplified in the power amplifier 124 and transmitted as a radio signal from the transmission antenna 126.

  Thus, a radio signal modulated by serial data of one channel is transmitted from the transmission antenna 126. For example, a one-channel radio signal having a transmission carrier frequency of 60 GHz and a band of about 1 GHz is transmitted. Echo data transmitted as a radio signal from the separation unit 120 is received by a receiving antenna (reference numeral 202 in FIG. 2) of the apparatus main body.

  Further, a radio signal transmitted from the transmission antenna (reference numeral 236 in FIG. 2) of the apparatus main body is received by the reception antenna 130 of the separation unit 120 shown in FIG. The power is amplified and then sent to the demodulator 134. The demodulator 134 performs demodulation processing on the radio signal subjected to modulation processing such as amplitude modulation, extracts an image signal, and outputs the image signal to the display image processing unit 136.

  Then, the display image processing unit 136 forms a display image from the image signal, and the formed display image is displayed on the monitor 138. Thereby, a display image corresponding to the ultrasonic image displayed on the monitor (reference numeral 222 in FIG. 2) of the apparatus main body is displayed on the monitor 138 provided in the separation unit 120.

  Thus, in the wireless ultrasonic diagnostic apparatus according to the present invention, an ultrasonic image is displayed on the monitor (reference numeral 138 in FIGS. 1 and 3) of the ultrasonic probe. For this reason, even when the distance between the operator of the ultrasonic probe and the apparatus main body is long, or even when the operator of the ultrasonic probe cannot face the apparatus main body, the ultrasonic probe displayed on the ultrasonic probe is displayed. A sound image can be easily confirmed.

  Moreover, since an ultrasonic image is formed by the apparatus main body (FIG. 2), it is not necessary to provide an image forming unit (reference numeral 220 in FIG. 2) having a relatively large signal processing scale in the ultrasonic probe. Therefore, for example, it is advantageous in terms of miniaturization of the ultrasonic probe and countermeasures against heat generation.

  FIG. 4 is an external view of the ultrasonic probe of the present embodiment, and FIG. 4 shows an external view of the ultrasonic probe of FIG.

  The ultrasonic probe shown in FIG. 4 includes a transducer 102 that transmits and receives ultrasonic waves. Since this ultrasonic probe is used by a user (examiner) in his / her hand with the vibrator 102 applied to the subject, it is desirable that the ultrasonic probe has a shape, size and weight that can be easily held in the hand. For example, the shape (appearance) of the ultrasonic probe is designed based on the shape of a conventionally known ultrasonic probe.

  However, the ultrasonic probe shown in FIG. 4 is provided with a monitor 138, operation buttons 142, and a speaker 144. On the monitor 138, an ultrasonic image formed by the apparatus main body (FIG. 2) is displayed. For this reason, the user can check the ultrasonic image with the monitor 138 of the ultrasonic probe that is held in hand. The operation button 142 can be used to operate, for example, setting of the measurement mode from the ultrasonic probe. Furthermore, by reproducing the Doppler sound obtained from the echo data by the speaker 144, for example, a heart sound can be confirmed.

  FIG. 5 is a diagram for explaining an example of use of the wireless ultrasonic diagnostic apparatus of the present embodiment. In FIG. 5, a user (inspector) 10 who uses a wireless ultrasonic diagnostic apparatus holds an ultrasonic probe (ultrasonic probe in FIG. 4) in his hand and makes a diagnosis by placing the ultrasonic probe on the abdomen of a patient 20. It shows how to do it.

  In FIG. 5, echo data obtained from a patient 20 as a subject is wirelessly transmitted from an ultrasonic probe, received by a receiving antenna 202 of the apparatus body, and supplied to the apparatus body. The apparatus main body 200 that has received the wireless signal via the receiving antenna 202 forms an ultrasound image relating to the diagnostic region of the patient 20 based on the wireless signal. Then, an image signal corresponding to the formed ultrasonic image is wirelessly transmitted from the apparatus main body to the ultrasonic probe, and the ultrasonic image is displayed on the monitor (reference numeral 138 in FIG. 4) of the ultrasonic probe. Of course, an ultrasonic image may be displayed on the monitor of the apparatus main body as in the past.

  As described above, in this embodiment, since an ultrasonic image is displayed on the monitor of the ultrasonic probe, the user 10 and the apparatus main body are separated from each other, or the user 10 cannot face the apparatus main body side. Even so, the ultrasonic image can be easily confirmed by the monitor displayed on the ultrasonic probe.

  FIG. 6 is an external view of a separation type ultrasonic probe, and FIG. 6 shows an external view of the ultrasonic probe of FIG. The ultrasonic probe of FIG. 6 has a configuration in which a probe main body 100 and a separation unit 120 are connected to each other via a cable 114.

  Since the probe main body 100 is used by a user (inspector) in his / her hand, it is desirable that the probe main body 100 has a shape, size and weight that are easy to hold in the hand. The shape (external appearance) of the probe main body 100 may be the same as the shape of a conventionally known ultrasonic probe.

  The separation unit 120 is attached to, for example, a bed on which a patient lies. Therefore, the separation unit 120 is provided with a mounting jig 146. Further, the separation unit 120 is provided with a monitor 138 and a speaker 144.

  On the monitor 138, an ultrasonic image formed by the apparatus main body (FIG. 2) is displayed. For this reason, the user can confirm an ultrasonic image by the monitor 138 of the separation unit 120 attached to a bed or the like. Further, for example, a heart sound can be confirmed by reproducing a Doppler sound obtained from the echo data by the speaker 144. Note that an operation button may be provided on the separation unit 120 so that, for example, the measurement mode can be set from the separation unit 120.

  The separation unit 120 is provided with a transmission antenna (not shown) (reference numeral 126 in FIG. 3) for wirelessly transmitting echo data acquired by the probe main body 100. Therefore, the separation unit 120 is attached to a bed or the like so that the transmission antenna is directed to the apparatus main body of the ultrasonic diagnostic apparatus.

  With the separation unit 120 attached to a bed or the like, the user makes a diagnosis by holding the probe main body 100 in his / her hand. Therefore, it is sufficient that the cable 114 is long enough to allow the user to move his / her hand freely while holding the probe main body 100 in his / her hand. Note that a mechanism that can change the length of the cable 114 may be provided so that the user can set the length of the cable 114 according to the diagnostic application. Further, power may be supplied from the separation unit 120 to the probe body 100 via the cable 114.

  FIG. 7 is a diagram for explaining an example of use of the separation-type ultrasonic probe (FIGS. 3 and 6). FIG. 7 shows a state in which a user (examiner) 10 who uses a wireless ultrasonic diagnostic apparatus holds the probe body 100 in his hand and makes a diagnosis by placing the probe body 100 against the abdomen of the patient 20.

  In FIG. 7, a separation unit 120 provided separately from the probe main body 100 is attached to a bed 300 on which the patient 20 lies. The echo data acquired by the probe main body 100 is transmitted from the separation unit 120 toward the receiving antenna 202 of the apparatus main body by a radio signal. The apparatus main body that has received the wireless signal via the receiving antenna 202 forms an ultrasound image related to the diagnostic region of the patient 20 based on the wireless signal. An image signal corresponding to the formed ultrasonic image is wirelessly transmitted from the apparatus main body to the separation unit 120, and the ultrasonic image is displayed on the monitor (reference numeral 138 in FIG. 6) of the separation unit 120. Of course, an ultrasonic image may be displayed on the monitor of the apparatus main body as in the past.

  When making a diagnosis using a separation-type ultrasonic probe, the user 10 operates the probe main body 100 while confirming an image displayed on the monitor of the separation unit 120. For this reason, an ultrasonic image can be easily confirmed by placing the separation unit 120 at a position where the user 10 can easily observe. Further, since the separation unit 120 is provided separately from the probe body 100, the separation unit 120 can be fixed regardless of the posture of the probe body 100.

  The separation unit 120 is provided with a transmission antenna (not shown) (reference numeral 126 in FIG. 3) for wirelessly transmitting echo data acquired by the probe body 100. Therefore, the separation unit 120 is attached so that the transmission antenna is directed to the reception antenna 202 of the apparatus main body. As a result, the transmission antenna is directed toward the apparatus main body 200 regardless of the posture of the probe main body 100, so that it is possible to suppress deterioration in transmission quality depending on the directivity of the radio signal.

  As mentioned above, although preferred embodiment of this invention was described, embodiment mentioned above is only a mere illustration in all the points, and does not limit the scope of the present invention. For example, an optical signal may be used as a radio signal instead of a radio signal.
