  • the "Basic Menu” field allows the operator to select “Surface of Body” or “Inside of Body”.
  • the “Option” field allows the operator to select at least one of "Oxygen Saturation", “Contrast Medium”, and "Ultrasonic Waves".
  • the reason why one of "Surface of Body” and “Inside of Body” can be selected in “Basic Menu” is that the wavelength of pulsed light applied to the object and the reception frequency of the photoacoustic waves can be roughly classified depending on whether the measurement is for the surface of body or the inside of body.
  • the operator selects measurement of the surface of body or measurement of the inside of body on the "Basic Menu” using a radio button 202.
  • the operator further selects options, such as "Oxygen Saturation”, “Contrast Medium”, and “Ultrasonic Waves” as necessary.
  • the "Oxygen Saturation” is an option item for calculating and displaying oxygen saturation in a image reconstruction region of the object.
  • the "Contrast Medium” is an option item that is selected when an object given a contrast medium is to be measured.
  • the "Ultrasonic Waves” is an option item for acquiring an ultrasonic echo image by applying ultrasonic waves to an object and detecting reflected ultrasonic waves.
  • the source of the ultrasonic waves applied to the object when “Ultrasonic Waves” is selected may be disposed on the ultrasonic probe 102.
  • a "Run” button 204 is pressed after "Basic Menu” and “Option” are selected, a source wavelength and a central reception frequency of photoacoustic waves suitable for the measurement mode are automatically determined by the apparatus control unit 107.
  • “Basic Menu” is an exclusive or, while “Option” allows the operator to select a plurality of choices at the same time.
  • the apparatus control unit 107 automatically sets the source wavelengths of the pulsed lights to 756 nm and 797 nm, and the central reception frequency of the ultrasonic probe 102 to 3 MHz. Since a breast needs to be measured to a depth of about 4 cm, near-infrared light having a long light penetration depth is used for source pulsed light.
  • the central reception frequency of the ultrasonic probe 102 is set to a low frequency of about 3 MHz to draw a relatively large structure, such as a tumor or a thick blood vessel in a breast.
  • oxygen saturation is superimposed on a sound level distribution for display.
  • Another method of display is displaying an image showing a sound level distribution and an image showing oxygen saturation side by side.
  • a method of display may either be automatically determined by the apparatus control unit 107 in response to selection of a measurement mode or be selected by the operator.
  • the apparatus control unit 107 automatically sets the source wavelength of the pulsed light to 580 nm, and the central reception frequency of the ultrasonic probe 102 to 20 MHz. This is because observation in the range of around 5 mm is enough to perform measurement on a skin or the like. This allows visible light with a wavelength shorter than that selected for measurement on "Inside of Body", that is, visible light with a short penetration length, to be used for the source wavelength.
  • the photoacoustic waves needs to be set to a high central frequency because photoacoustic waves have to be detected at high resolution. Since the central reception frequency differs between measurement on "Surface of Body” and measurement on “Inside of Body”, the resolution of measurement differs. This results in different pixel resolutions of the images. Therefore, for measurement on “Surface of Body”, interpolation may be performed to prevent the difference in resolution from being viewed in the displayed images.
  • “Surface of Body” is a relatively shallow region from the surface of the object to a depth of about 1 cm.
  • the source wavelength is 780 nm.
  • a menu that prompts the operator to select the kind of contrast medium may be further displayed.
  • the apparatus control unit 107 selects a source wavelength suitable for the contrast medium given to the object.
  • time-series images are displayed as a method of displaying images. An image displayed on the display device 108 may be switched in sequence in a slide show format, or alternatively, a plurality of images may be displayed side by side in one window. A difference from the first image may be displayed to make it easy to know a change with time.
  • an image showing oxygen saturation may be interposed on an image acquired by measuring ultrasonic waves, of ultrasonic waves applied by the ultrasonic probe 102, reflected by the object.
  • the ultrasonic probe 102 switches between reception of photoacoustic waves and transmission and reception of ultrasonic waves for usage.
  • an item button 203 can be used. For example, when a "Surface of Body” button is pressed, setting for a part, such as a face, an arm, or a neck, and an observation target, such as a melanoma or a tumor, can be performed. Although the setting in this case is classified into “Surface of Body” and "Inside of Body", a selection window for measurement parts, such as a face, an arm, a neck, and a breast, may be displayed. For each of the parts, "Option" as shown in Fig. 2 may be set.
  • a plurality of ultrasonic probes 102 with different central reception frequencies may be provided so that an ultrasonic probe 102 to be used can be changed depending on the details of "Basic Menu” and "Option” selected by the operator.

  • the operator selects "Inside of Body” in "Basic Menu” and selects "Oxygen Saturation” and “Ultrasonic Waves” in “Option”.
  • Step S3 is the process of determining measurement conditions corresponding to the measurement mode selected at step S2. Since "Inside of Body”, “Oxygen Saturation”, and “Ultrasonic Waves” are selected at step S2, the apparatus control unit 107 sets two source wavelengths 756 nm and 797 nm for the pulsed light and sets the central reception frequency of the photoacoustic waves detected by the ultrasonic probe 102 to 3 MHz. When a plurality of light sources are used, the optical path of light emitted from a light source corresponding to a wavelength selected as necessary is switched so that the light is applied to a target region of the object. At this step, the ultrasonic wave circuit is switched between transmission and reception of ultrasonic waves. After completion of the setting, the process goes to step S4.

  • the photoacoustic measurement is performed for both of a wavelength of 756 nm and a wavelength of 797 nm of the pulsed light. In this case, the ultrasonic waves probe 102 switches the central reception frequency between 3 MHz and 12 MHz using an electrical filter.

If the target object is a breast, the same measurement is performed on the other breast of the identical object as needed. If the operator determines that repeated measurement is necessary, or the same measurement is to be performed on the other breast, the process returns to step S4 for measurement.
  • step S7 the operator determines whether the measurement conditions need to be changed.
