1. An ultrasound diagnosis apparatus comprising:
a scan controlling circuit configured to, when performing an ultrasound scanning process on a subject into whom a puncture needle has been inserted, cause an ultrasound probe to perform a first scanning process by transmitting an ultrasound wave in a first direction with respect to a surface of a vibrator for a purpose of taking an image of a tissue of the subject and a second scanning process by transmitting an ultrasound wave in each of a plurality of directions that are different from the first direction with respect to the surface of the vibrator;
an image generating circuit configured to generate a tissue image representing the tissue of the subject based on the first scanning process and to generate a needle image in which the puncture needle is emphasized based on the second scanning process;
an image synthesizing circuit configured to generate a synthesized image based on the tissue image and the needle image generated by the image generating circuit, wherein
when a puncture mode is not selected, the scan controlling circuit causes the ultrasound probe to perform the first scanning process and the image generating circuit generates the tissue image, and when the puncture mode is selected, the scan controlling circuit causes the ultrasound probe to perform the first scanning process and the second scanning process and the image generating circuit generates the synthesized image.
 
2. A method for generating an image comprising:
when performing an ultrasound scanning process on a subject into whom a puncture needle has been inserted, causing an ultrasound probe to perform a first scanning process by transmitting an ultrasound wave in a first direction with respect to a surface of a vibrator for a purpose of taking an image of a tissue of the subject and a second scanning process by transmitting an ultrasound wave in each of a plurality of directions that are different from the first direction with respect to the surface of the vibrator;
generating a tissue image representing the tissue of the subject based on the first scanning process and generating a needle image in which the puncture needle is emphasized based on the second scanning process;
generating a synthesized image by synthesizing together the tissue image and the needle image generated by the image generating circuit, wherein when a puncture mode is not selected, causing the ultrasound probe to perform the first scanning process and generating the tissue image and when the puncture mode is selected, causing the ultrasound probe to perform the first scanning process and the second scanning process and generating the synthesized image.
 
3. An ultrasound diagnosis apparatus comprising:
a scan controlling circuit for controlling a first scanning process and or a second scanning process based upon a puncture mode input, the first scanning process transmitting an ultrasound wave at a first predetermined single angle with respect to a surface of a vibrator over a certain distance towards a tissue of the subject while the second scanning process transmitting an ultrasound wave at a plurality of angles that are each different from the first predetermined single angle with respect to the surface of the vibrator over the certain distance towards a puncture needle;
an image generating circuit for generating a tissue image representing the tissue of the subject based on the first scanning process and a needle image of the puncture needle based on the second scanning process;
an image synthesizing circuit for generating a synthesized image based on the tissue image and or the needle image generated by the image generating circuit.
