[Description of Fig. 2]

2 is a diagram of a pulse generator according to another embodiment of the present invention.

FIG. 2 is a limited interface because [B-2] is configured with a programmable logic device (PLD) such as an FPGA or an application-specific integrated circuit (ASIC). In order to avoid a resource, a block [h] including a second switch part of the company is designed.

That is, in the embodiment of FIG. 2, when [B-2] is an on-chip designed with an FPGA or an ASIC, the number of pins of the connection portion of FIG. 2C is 1/2. By reducing it, you can help improve system performance.

[B-2] includes a diagnostic pulse generator (DPG) and a therapeutic pulse generator (TPG), and again includes a mode selector (see [character] in FIG. 2) for selectively outputting the two inputs. It is output to the 2nd switch part (refer [G] of FIG. 2) through. At this time, the second switch unit controls the pulse generated in the DPG or TPG to the FET_DP (see [C] in FIG. 2) or FET_TP (see [D] in FIG. 2) under the control of the controller (refer to [A] in FIG. 2).

[Description of Fig. 3]

3 is a diagram of a pulse generator according to another embodiment of the present invention.

3 is a structure using a single FET, the output of [b-2] is delivered to one FET [car], the output from the one FET is delivered to the transformer [e]. Therefore, at this time, one FET [difference] has an operating characteristic range for delivering the DPG / TPG pulse which is the output of [B-2] to (e).

That is, according to another embodiment of the present invention, as a pulse generating device for ultrasound diagnosis and treatment,

A pulse generator including a first pulse generator (DPG in FIG. 3) for generating a diagnostic pulse and a second pulse generator (TPG in FIG. 3) for generating a treatment pulse; A mode selector connected to the first pulse generator and the second pulse generator (see Fig. 3); One FET receiving the pulse output from the mode selector (see [difference] in FIG. 3); The controller may include the first and second pulse generators and a controller (see [a] of FIG. 3) for controlling the operation of the mode selector.

In this case, the control unit selectively outputs a first driving control signal for driving the first pulse generator and a second driving control signal for driving the second pulse generator so that the diagnostic pulse or the therapeutic pulse is the first pulse. The controller may be selectively output from the pulse generator and the second pulse generator, and the operation of the mode selector may be controlled such that any one of the diagnostic pulse and the therapeutic pulse is input to the FET.

4 is a control flowchart of a pulse generation method that may correspond to the above FIGS. 1 and 2, and FIG. 5 is a control flowchart of a pulse generation method that may correspond to FIG. 3.

For this, it will be easy to understand the flow according to the flow chart through the above Figures 1 to 3, but this is briefly described as follows.

 [Description of Fig. 4]

First, in step S40, the control unit shown in FIG. 1 or 2 (refer to [a] of FIG. 1 or [a] of FIG. 2) may be any one of a diagnostic pulse generator DPG and a therapeutic pulse generator TPG. Outputs a drive control signal for controlling the drive of the DPG or TPG.

Accordingly, in step S42, a diagnostic pulse or a treatment pulse is generated from the DPG or the TPG in accordance with the drive control signal from the controller. That is, when the first driving control signal for operating the diagnostic pulse generator DPG is output from the controller, the DPG receiving the generated pulse generates a diagnostic pulse, and the second driving control signal for operating the therapeutic pulse generator TPG is provided. If output, the received TPG generates a therapeutic pulse.

Thus, the pulse generated from the DPG or TPG is transferred to the FET_DP (see [C] in FIG. 1) or the FET_TP (see [D] in FIG. 1) directly according to the configuration as shown in FIG. 1 (S45 and S46). Reference). That is, according to the configuration of FIG. 1, step S44 is omitted in FIG. 4.

As another example, according to the configuration as shown in Fig. 2, the pulse generated from the DPG or TPG is stepped by a mode selector (see Fig. 2) and a second switch unit (see Fig. 2). After the same process as in S44, the process is transferred to FET_DP (see [C] in FIG. 2) or FET_TP (see [D] in FIG. 2) (see S45 and S46). That is, in FIG. 2, the mode selector and the second switch unit may determine in which path the received pulse is output based on the value of the control signal (see “Pulse_Sel” in FIG. 4) received from the controller. In this regard, for example, as shown in the flowchart, the mode selector and the second switch unit output the received pulse to the FET_DP when the value of "Pulse_Sel" is 0, and FET_TP when the value is 1, on the contrary. Will output

Subsequently, in step S48, the first switch unit (refer to [e] in FIG. 1 or [e] in FIG. 2) is received toward the diagnostic probe when the value is 0 according to the value of "Pulse_Sel", as described above. The pulse is delivered, and if the value is 1, the pulse is received toward the therapeutic probe. Through this flow chart, it is possible to determine which pulse transmitter (which can be implemented in the form of a probe, for example) of the diagnostic pulse and the therapeutic pulse. Of course, this may be irrelevant to the core features of the present invention, but the pulse transmitter outputting the diagnostic pulse and the therapeutic pulse may be manufactured in the form of a single probe.

Hereinafter, the flowchart of FIG. 5 will be described. FIG. 5 relates to the configuration of FIG. 3 above.

[Description of Fig. 5]

Steps S50 and S51 correspond to steps S40 and S42 of FIG. 4 described above, and a detailed description thereof will be omitted. In addition, step S53 is also performed in the mode selector of FIG. 3 (see [G] of FIG. 3), which is a process corresponding to step S44 of FIG. 4 described above, and a detailed description thereof will be omitted.

Since only one FET (see [difference] in FIG. 3) is used in the configuration of FIG. 3, steps S55 and S56 are added in the flowchart of FIG. 5. That is, when the value of "Pulse_Sel" is 0, the diagnostic pulse should be output toward the diagnostic pulse transmitter (for example, the diagnostic probe, see DP_TX in FIG. 5), so that the diagnostic pulse transmitter is turned on ("DP_TX_Sel" in FIG. 5). 1). Conversely, when the value of "Pulse_Sel" is 1, since the diagnostic pulse should be output toward the therapeutic pulse transmitter (for example, the diagnostic probe, see TP_TX in FIG. 5), the therapeutic pulse transmitter is turned on ("TP_TX_Sel in FIG. 5"). "= 1). In this manner, both a diagnostic pulse and a therapeutic pulse can be output as needed while using a single FET. In this case, the diagnostic pulse transmitter and the therapeutic pulse transmitter may be manufactured as independent probes, but may be manufactured in the form of a single probe.

Although the above has been described with reference to embodiments of the present invention, those skilled in the art may variously modify the present invention without departing from the spirit and scope of the present invention as set forth in the claims below. And can be changed easily.
