ULTRASONIC IMAGING SYSTEM WITH BODY MARKER ANNOTATIONS
An ultrasonic diagnostic imaging system is operated to acquire an ultrasound image of a region of the body containing suspect anatomy such as a suspected lesion. A body marker template of the region of the body is displayed on a touchscreen display of the imaging system. The operator records the location of the suspect anatomy by touching a corresponding point on the body marker template displayed on the touchscreen display. The mark on the template can be finely adjusted by one or more controls on the imaging system control panel. The body marker template can also record a graphic indicating the orientation of the ultrasound probe relative to the body when the suspect anatomy was imaged. A report generator produces a report containing both the ultrasound image of the suspect anatomy and the body marker template with the indicated location of the suspect anatomy.
The present application is a continuation of U.S. patent application Ser. No. 15/899,426 filed Feb. 20, 2018, which is a continuation of U.S. patent application Ser. No. 15/646,439 filed Jul. 11, 2017, which is a continuation of U.S. patent application Ser. No. 11/576,494 filed Apr. 2, 2007, now U.S. Pat. No. 9,713,458, which is the U.S. National Phase application under 35 U.S.C. § 371 of International Application No. PCT/IB2005/053251, filed Oct. 3, 2005, which claims the benefit of U.S. Provisional Application Ser. No. 60/617,493 filed Oct. 8, 2004. These applications are hereby incorporated by reference herein.
This invention relates to ultrasonic diagnostic imaging systems and, in particular, to ultrasonic imaging systems in which the results of an ultrasonic diagnosis are recorded in a template corresponding to the body region being diagnosed.
Many ultrasound examinations require that the results of the exam be annotated in a way which records the location in the body of a lesion or suspicious finding. One way to do this is for the ultrasonographer to delineate the location of the abnormality on the ultrasound image graphically with labels, measurements, and icons of the pertinent anatomy. This technique is desirable when the ultrasound images are to be transferred to another clinician who is skilled in reading ultrasound images, such as a radiologist or surgeon, particularly in applications where the anatomic location is not obvious based on surrounding structures.
However, the results of an ultrasound exam frequency are forwarded to a referring physician who may not routinely read ultrasound images. In such case the diagnostic report benefits from a template which schematically represents the region of the body being diagnosed. The location of a lesion or other abnormality can be marked on the template, clearly showing the location of the abnormality to someone who is unfamiliar with the subtleties of ultrasound images. An example of a body marker graphic is given in U.S. Pat. No. 6,500,118, for instance. The selection of a body marker and use of a lesion locator tool such as this is done at the time of the exam so that the operator can clearly convey lesion or transducer location at the time of the study. This is usually done by selecting the desired template from a file of templates, then keying the annotation information of the abnormality onto the template image. This traditional technique can be overly time-consuming as the user manipulates graphics over the template with a cursor or other graphic control, at a time when it is desirable to finish the examination and the report as efficiently as possible. Accordingly it is desirable to improve the speed and accuracy with which the annotation of the examination results is performed.
In accordance with the principles of the present invention, an ultrasound system has an image display on which an ultrasound image being read is displayed, and a touchscreen display on which a body marker template is displayed. The clinician annotates the location of an abnormality by simply touching the corresponding point on the touchscreen display while observing the ultrasound image, making template annotation quick and simple. Unlike the conventional body marker user interface, the touchscreen template display can be operated by one hand. The clinician is thus not constrained to annotating only frozen images, but can enter annotations by touching the template screen with one hand while continuing to hold the ultrasound probe in contact with the patient for continuous acquisition of real time ultrasound images. In an illustrated embodiment the template annotation also enables the clinician to easily record the position of the ultrasound probe when the image of the abnormality was being acquired. Recording this information enables the abnormality to be quickly reacquired during a subsequent imaging session such as when the abnormality is being diagnosed again or treated.

Referring first to
In operation, a probe which is plugged into one of the connectors 26 is placed against the skin of a patient (not shown) and a particular anatomy of the patient such as the breast or heart is imaged on the image display 16. The images may be examined as they are acquired in real time, or selected images may be frozen and stored. A body marker template corresponding to the anatomy being examined is accessed and displayed on the touchscreen display 18, either at the start of the examination or when particular pathology is diagnosed in one of the images on the display. The ultrasonographer with then mark the location of the pathology on the template by simply touching the appropriate location on the template and/or making further refinements as discussed more fully below. The template can then be incorporated into the diagnostic report along with one or more of the images showing the abnormality as discussed below.
A block diagram of an ultrasound system constructed in accordance with the principles of the present invention is shown in
The ultrasound system is operated by a user who manipulates the appropriate controls of a control panel 54. Signals from the control panel are received by the controller 50 which responds by controlled the ultrasound system as desired by the operator. In accordance with the present invention, the user can use the control panel to call up a body marker template for display on the touchscreen display 18. Alternately, the ultrasound system may call up a particular template in correspondence with selection by the user of a particular ultrasound exam. For instance, if the user indicates that a breast exam will be performed, the ultrasound system may call up the templates for a breast diagnosis. The graphical templates are applied to a graphics generator 56, which applies the graphics signals to a touchscreen controller 58, which drives the touchscreen display appropriately to display the selected template. Located below the touchscreen display as seen in
Located in a row 110 at the bottom of the touchscreen display 18 are five softkeys. These softkeys are operated by the control knobs 20 located below the respective softkeys. In this embodiment only the first three softkeys are used and are controlled by knobs 112 a, 112 b, and 112 c.
When the user finds an abnormality in a breast image on the image display 16, the location of the abnormality in the breast is annotated on the breast template as shown in
This embodiment also enables the sonographer to indicate the position of the probe when the ultrasound image shown on the image display 16 was acquired. This information will enable the abnormality to be imaged in the same way in a subsequent exam or treatment procedure. The front template 104 is seen to have a rectangular graphic 120 c positioned over the abnormality marker 120 b. This rectangular graphic corresponds to the rectangular shape of the transducer array 32 of the probe. In this embodiment the rectangular probe graphic 120 c automatically appears over the abnormality marker 120 b. The probe graphic must then be adjusted by the sonographer which is done by turning softkey knob 112 a. This causes the rectangular graphic to rotate about its center until it is in the same position that the sonographer was holding the probe when the image being annotated was acquired. Similar to the other softkeys, the probe orientation softkey has a rectangular graphic which rotates in the same manner as the probe graphic 120 c. With the probe graphic properly positioned the abnormality can be imaged in the same manner as shown in the currently display image at a later date.
While the templates may be indexed in a file system on the ultrasound system and called up by the user addressing the appropriate body marker template, it is sometimes desirable to have the templates called up and displayed automatically. This may be done when the user is carrying out a diagnostic protocol, a series of exam steps, which has been pre-programmed on the ultrasound system. In such case the selection of each step of the protocol by the user would automatically call up and display the appropriate body marker template for the imaging procedure of that step. This obviates the need to manually search for and call up the template for each imaging procedure of the protocol. Transition from one marker template to another (including left/right and annotations) is driven by the protocol, which are then modified by the user through the easy touchscreen interface.
