[0065] FIG. 1 is a block diagram showing an ultrasonic diagnostic apparatus 100 based on the first embodiment.

[0066] The ultrasonic diagnostic apparatus 100 includes: a convex probe 1C having a number of M vibrating elements; a linear probe 1L having a number of M vibrating elements; a fan-shaped probe 1S having a number of L vibrating elements; a high-voltage switch 2 , including switches with a quantity of M; transmitter / receiver 3 of N channels; B / M mode processor 4; CFM (color flow matching) processor 5; PDI (power Doppler image) processor 6; DSC (digital scan converter) 7 ; display 8 ; controller 9 ; and input device 10 .

[0067] FIG. 2 is an explanatory diagram showing connections between the sector probe 1S, the high voltage switch 2 and the transmitter / receiver 3 in the first embodiment. In this embodiment, the parameters are set to N=32, M=128 and L=64.

[0083] FIG. 7 is an explanatory diagram showing the connection between the sector probe 1S, the high voltage switch 2 and the transmitter / receiver 3 of the second embodiment. In this embodiment, the parameters are set to N=32, M=128 and L=64.

[0084] The nth channel is connected in parallel to the nth switch, the (n+32)th switch, . . . , the (n+96)th switch, where n is 0-31.

[0085] The sector probe 1S has its 0th to 63rd vibration elements connected to the 0th to 63rd switches, respectively.

[0086] The controller 9 turns on the 16th to 47th switches, and turns off other switches connected to the vibrating element. As a result, only the 16th to 47th switches located in the central portion of the arrangement of the vibrating elements are driven.

[0087] FIG. 8 is an explanatory diagram showing the correspondence relationship between the channels of the transmitter / receiver 3 of the second embodiment and the vibrating element 1S of the sector probe. The vibrating element...

[0091] FIG. 9 shows an explanatory diagram of the connection between the sector probe 1S, the high voltage switch 2 and the transmitter / receiver 3 of the third embodiment. In this embodiment, the parameters are set to N=32, M=128 and L=128.

[0092] The nth channel is connected in parallel to the nth switch, the (n+32)th switch, . . . , the (n+96)th switch, where n is 0-31.

[0093] The sector probe 1S has its 0th to 63rd vibration elements connected to the 0th to 63rd switches, respectively.

[0094] The mth to (m+31)th switches are combined into a (m / 32)th switch group.

[0095] The controller 9 selects 32 vibrating elements positioned at a constant or virtually constant pitch and not connected to the same channel, turns on only 32 switches, and turns off the other switches connected to the vibrating elements. As a result, only 32 vibrating elements distributed at a constant or virtually constant pitch in the array of vibrating elements are driven.

Abstract

The transmitter / receiver for a convex probe and linear probe are used to drive a sector probe. Usually, when an ultrasound diagnostic apparatus using a convex probe and linear probe uses a sector probe, it selects vibration elements of N in number, which is equal to the number of channels of the sector probe, out of vibration elements of L in number (N is smaller than L), so that the selected elements are distributed at a virtually constant pitch in the alignment of vibration elements, and turns on only high voltage switches which are connected with the selected vibration elements to implement the sector scanning with the transmitter / receiver. It becomes possible to implement the sector scanning by using the transmitter / receiver having channels less than the number of vibration elements of the sector probe.

Description

technical field [0001] The present invention relates to a sector probe driving method and ultrasonic diagnostic apparatus, and more particularly to a sector probe driving method and ultrasonic diagnosis capable of driving sector probes by using transmitters / receivers for convex probes and linear probes device. Background technique [0002] An ultrasonic diagnostic apparatus using a convex probe and a linear probe is equipped with: a transmitter / receiver having 0th to 31st channels; a high-voltage switch including, for example, 0th to 127th switches, wherein the nth channel— n takes each of 0 to 31 - connect in parallel to the nth switch, the (n+32)th switch, ..., the (n+96)th switch. The 0th to 127th switches are respectively connected to the 0th to 127th vibrating elements of the male probe and the linear probe. Only the 0th to 31st switches are turned on to drive the 0th to 31st vibration elements, then only the 1st to 32nd switches are turned on to drive the 1st to 32nd...
