Problems solved by technology

[0006] However, such a manual setting device requires a large space for many sliding volumes in the operating part of the ultrasound imaging apparatus
If the number of sliding volumes is reduced to save space, the accuracy of the time gain control is reduced due to the reduced number of points controlling the time gain curve

Embodiment Construction

[0046] Several embodiments of the present invention are described in detail with reference to the accompanying drawings. It should be noted that the present invention is not limited to these examples. attached figure 1 Shown is a block diagram of an ultrasound imaging apparatus, which is an embodiment of the present invention. The structure of the device represents an embodiment of the device according to the invention. The operation of the device represents one embodiment of the method according to the invention.

[0047] as attached figure 1 As shown, the device has an ultrasound probe 2. The ultrasound probe 2 has an array of ultrasound transducers (not shown). The individual ultrasonic transducers are fabricated from piezoelectric materials such as PZT (lead zirconate titanate [Pb-Zr-Ti]) ceramics. The user applies the ultrasound probe 2 against the target 4 .

[0048] The ultrasound probe 2 is connected to the transceiver section 6 . The transceiver section 6 sends ...

Abstract

In order to perform precise time-gain control using a small manual setting device, one of two-dimensional coordinates of a position on a surface of a tablet pointer which an external object touches is defined as a coordinate on a time axis, and the other as a coordinate on a gain axis; and the time gain is controlled based on the two-dimensional coordinates. In order to provide an ultrasonic imaging apparatus that responds to the requirement for both portability and versatility, the ultrasonic imaging apparatus comprises a portable imaging apparatus comprising ultrasonic imaging means, and a support apparatus which comprises supporting means for supporting extension of functions of the imaging apparatus, and which is electrically connected to and mechanically joined to the imaging apparatus so that it can be removably combined with the imaging apparatus.

Description

technical field [0001] The present invention relates to a time gain control method and equipment, recording media and ultrasonic imaging equipment, in particular, to a method and equipment for controlling the time gain of echo reception, and a record for enabling a computer to perform this time gain control function A recording medium of a program and an ultrasonic imaging device including such a time gain control device. Background technique [0002] An ultrasonic imaging device scans the interior of a target to be imaged; receives echoes; and generates a B-mode image corresponding to the intensity of the echoes for display. [0003] During reception of echoes, time gain control (TGC) is performed. The time gain control controls the gain of the echo reception according to the return time of the echo (ie, the depth of the reflection point of the echo) to correct the brightness of the B-mode image to prevent the brightness decrease with the increase of the depth. [0004] T...
