ULTRASOUND DIAGNOSIS APPARATUS
The ultrasound diagnosis apparatus is provided capable of preventing visibility of the ultrasound image from being impaired when piercing a puncture needle. The ultrasound diagnosis apparatus according to the embodiments includes an image processor and a display controller. The image processor generates an ultrasound image based on echo signals received by the ultrasound probe. The display controller causes a display unit to display, along with the ultrasound image, a marker which indicates allowable change range for the orientation of the puncture needle defined by the guide mechanism for guiding the puncture needle to the puncture target part.
1 . An ultrasound diagnosis apparatus, comprising:
an ultrasound probe configured to transmit/receive ultrasound waves;
a guide mechanism which is provided directly or indirectly to the ultrasound probe and has a wall unit configured to regulate so as to allow an angle with which a puncture needle is guided to a puncture target part within a predetermined range;
an image processor configured to generate an ultrasound image from echo signal received by the ultrasound probe;
a display configured to display the ultrasound image; and
a marker output unit configured to output a marker indicating the inclination of the wall unit on the display.
2 . The ultrasound diagnosis apparatus according to claim 1 , wherein the marker output unit is configured to identify an output position of the marker corresponding to the position of the guide mechanism from the position relationship between the ultrasound probe and the ultrasound image so as to output the marker at the identified output position.
3 . The ultrasound diagnosis apparatus according to claim 2 , comprising:
a storage configured to store guide mechanism information including the shape and the position of the guide mechanism;
a selection unit configured to select the guide mechanism information corresponding to the guide mechanism for use from the guide mechanism information stored in the storage; and
a marker creator configured to create the marker based on the guide mechanism information selected by the selection unit.
4 . An ultrasound diagnosis apparatus, comprising:
an ultrasound probe configured to transmit/receive ultrasound waves;
a guide mechanism which is provided directly or indirectly to the ultrasound probe and is configured to guide an puncture needle to a puncture target part;
an image processor configured to generate an ultrasound image from echo signals received by the ultrasound probe;
a display configured to display the ultrasound image; and
an area suggestion unit configured to suggest an area in which an image of the puncture needle based on the shape of the guide mechanism can appear on the display.
5 . The ultrasound diagnosis apparatus according to claim 4 , wherein the area is the area sandwiched between two boundary lines indicating a limit in which the puncture needle can be pierced along the wall unit of the guide mechanism, and the area suggestion unit is configured to identify the output positions of the two boundary lines corresponding to the position of the guide mechanism from the position relationship between the ultrasound probe and the ultrasound image so as to output the two boundary lines at the output positions.
6 . The ultrasound diagnosis apparatus according to claim 5 , comprising:
a storage configured to store guide mechanism information including the shape and the position of the guide mechanism;
a selection unit configured to select the guide mechanism information corresponding to the guide mechanism for use from the guide mechanism information stored in the storage; and
a boundary line creator configured to create the two boundary lines based on the guide mechanism information selected by the selection unit.
7 . An ultrasound diagnosis apparatus, comprising:
an ultrasound probe configured to transmit/receive ultrasound waves;
a guide mechanism which is provided directly or indirectly to the ultrasound probe and is configured to guide a puncture needle to a puncture target part;
an image processor configured to generate an ultrasound image from echo signals received by the ultrasound probe;
a display configured to display the ultrasound image;
a marker output unit configured to output a marker imitating the shape for the guide mechanism on the display; and
an area suggestion unit configured to suggest an area in which an image of the puncture needle based on the shape of the guide mechanism can appear on the display.
8 . An ultrasound diagnosis apparatus, comprising:
an image processor configured to generate an ultrasound image based on echo signals received by an ultrasound probe; and
a display controller configured to cause a display unit to display, along with the ultrasound image, a marker indicating an allowable change range for an orientation of a puncture needle defined by a guide mechanism for guiding the puncture needle to a puncture target part.
9 . The ultrasound diagnosis apparatus according to claim 8 , wherein the marker is configured to indicate the allowable change range defined by the shape of the guide mechanism.
10 . The ultrasound diagnosis apparatus according to claim 8 , wherein the marker is configured to indicate the allowable change range defined by the shape of the wall unit of the guide mechanism.
11 . The ultrasound diagnosis apparatus according to claim 8 , wherein the display controller is configured to cause the marker to be displayed at a position adjacent to the ultrasound image.
12 . The ultrasound diagnosis apparatus according to claim 8 , wherein the display controller is configured to cause the marker to be displayed based on the positions of the ultrasound probe and the guide mechanism.
13 . The ultrasound diagnosis apparatus according to claim 1 , wherein the image processor is configured to generate an ultrasound image from echo signals received by the ultrasound probe in a state where at least most of the guide mechanism is inserted into a subject.
