  • the invention relates to an apparatus, a method and a computer program for displaying icons representing medical objects.
  • Medical imaging is in wide spread of use as a diagnostic tool in hospitals today.
  • Different digital imaging modalities e.g. CT, MRI, X-ray, PET, SPECT are used in various clinical situations, ranging from managing emergency situations to long-term screening, for example, breast screening or therapy monitoring like chemo or radiation therapy.
  • an apparatus for displaying icons representing medical objects comprising medical object attributes comprises: a display for displaying the icons,
  • a position determining unit for determining positions of the icons on the display depending on a first medical object attribute being a time and a second medical object attribute, wherein a first dimension of a position of an icon is determined depending on a value of the first medical object attribute and a second dimension of the position of the icon is determined depending on a value of the second medical object attribute,
  • an arranging unit for arranging the icons on the display in accordance with the determined position.
  • the medical objects are not only arranged depending on the time, but also depending on another medical object attribute, not only objects having different times are shown at different positions on the display, but also medical objects having the same time and being different with respect to the second medical object attribute. Different medical objects can therefore be distinguished easier and can be shown in a more sorted way, thereby allowing a user to more easily comprehend medically relevant information.
  • the display is preferentially a two-dimensional display, which shows a two-dimensional diagram.
  • the diagram can be regarded as a desktop and depicts a graphical overview of the medical objects, which are preferentially currently at the user's disposal for review.
  • the icons represent medical imaging studies comprising images.
  • the first medical object attribute is, for example, a date at which the images of the medical imaging study have been acquired.
  • the images of the study comprise preferentially image tags and the second medical object attribute is preferentially an image tag, which has the same tag value for each image of the study.
  • the icons can also represent non-image based objects or clinical events.
  • the icons can represent radiotherapy plans or clinical events like a "biopsy" event. Radiotherapy plans can be stored in, for example, a DICOM format in an image archive, which may be a central image archive on which all images of, for example, a hospital are stored or a local image archive of, for example, the apparatus for displaying the icons.
  • Displaying a radiotherapy plan may emphasize the start of a therapy.
  • Clinical events like a "biopsy event” may indicate that the user has to expect signs of scars in later image studies.
  • the clinical events may be entered by the user into the apparatus for displaying icons or may be imported from a storing unit of, for example, another system.
  • Medical objects are objects which are related to healthcare.
  • medical objects are preferentially objects containing information which is related to the maintenance and/or restoration of health by diagnosis and/or treatment of illness.
  • the medical objects are preferentially medical imaging studies, medical images, therapy plans like radiotherapy plans and/or clinical events like the above mentioned biopsy event.
  • a medical object can be a single element or a medical object can be a set of elements.
  • a medical object can be a single medical image or a medical object can be a set of medical images like a DICOM study or a DICOM series.
  • the medical object can also be a single DICOM object or a set of DICOM objects of another type like therapy plans, for example, radio therapy plans, DICOM structured reports, et cetera.
  • therapy plans for example, radio therapy plans, DICOM structured reports, et cetera.
  • a medical object comprises a set of elements, these elements have preferentially the same first medical object attribute value and the same second medical object attribute value.
  • each icon represents a single DICOM study
  • the second medical attribute is chosen such that the elements of the DICOM study have the same second medical attribute value.
  • the second medical object attribute is preferentially a DICOM tag or another tag assigned to the medical objects.
  • the DICOM tag "Body Part Examined” defines, for example, the head, the thorax, the abdomen, et cetera.
  • the DICOM tag "Modality” defines the type of the imaging modality, which has been used for acquiring the medical object.
  • the imaging modality type is, for example, magnetic resonance imaging, positron emission tomography imaging, x-ray, computed tomography imaging, ultrasound imaging, single photon emission computed tomography imaging, secondary capture, structured report, et cetera.
  • the DICOM tag "Station Name” defines preferentially the acquisition unit at which the medical objects have been acquired.
  • the second medical object attribute may be selected from a set of supplementary tags which have been assigned to the objects after acquisition, for example, by manually entering information on the same or another system or by an automatic or semiautomatic preprocessing of the medical objects on the same or another system. For instance, one may assign an attribute to each medical object which relates the object to a certain worklist, for example, a list containing all objects to be processed by a specific expert or a list containing all objects acquired within a certain clinical process like regular breast cancer screening. Another example is a full-automatic preprocessing module, which recognizes the examined body region based on image data of the medical object and stores this information in a supplementary attribute.
  • the position determining unit can be adapted to determine the first dimension of the position of the icon by using a function for mapping the medical object from the temporal dimension to the spatial dimension on the display.
  • the function is preferentially strictly monotonically increasing and can be linear.
  • the position determining unit is adapted to determine the second dimension of the position of the respective icon such that this second dimension is different for different values of the respective second medical object attribute.

  • the first medical object attribute is the time, in particular, a study or series related date if a medical object is a study or a series
  • the second medical object attribute reflects the patient, the examined body region, the modality, the acquisition unit or other information
  • an arrangement of the icons representing medical objects can be provided, which shows the icons in a medically particularly reasonable way, thereby further improving the user's comprehension of the medically relevant information.

  • the user interface can further be adapted to allow a user to select a medical object attribute, which represents a time, in particular, which represents a date, as- signed to the medical objects as the first medical object attribute. This allows a user to adapt the arrangement, in particular, the two-dimensional diagram, such that it best suits his/her clinical task at hand.
  • the apparatus comprises a group icon providing unit for providing a group icon representing a group of medical objects comprising medical group attributes, wherein

  • the arranging unit is adapted to arrange the group icon on the display in accordance with the determined position of the group icon.

Abstract

La présente invention se rapporte à un appareil permettant d'afficher des icônes représentant des objets médicaux comprenant des attributs d'objets médicaux. L'appareil selon l'invention (1) comprend : un dispositif d'affichage (2), adapté pour afficher les icônes (6); et un module de détermination de position (3), adapté pour déterminer des positions des icônes (6) sur le dispositif d'affichage (2). La détermination des positions des icônes se fait sur la base d'un premier attribut d'objet médical, qui est un attribut temporel, et d'un second attribut d'objet médical. L'invention est caractérisée en ce qu'une première dimension d'une position d'une icône (6) est déterminée sur la base d'une valeur du premier attribut d'objet médical et qu'une seconde dimension de la position de l'icône (6) est déterminée sur la base d'une valeur du second attribut d'objet médical. L'appareil selon l'invention comprend par ailleurs un module de configuration (4), adapté pour configurer les icônes (6) sur le dispositif d'affichage (2) en fonction de la position déterminée.
