Abstract: A radiation therapy system (1) includes an ultrasound (US) imaging unit (2), a registration unit (30), an US motion unit (44), and a real-time dose computation engine (46). The ultrasound (US) imaging unit (2) generates a baseline and real-time US images (3) of a subject body (4) region including a target and one or more Organs At Risk (OARs). The registration unit (30) deformably registers a planning image (32) and the baseline US image (36), and maps (66) radiation absorptive properties of tissue in the planning image (32) to the baseline US image (36). The US motion unit (44) measures motion of the target volume and OARs during radiation therapy treatment based on the real-time US images. The real-time dose computation engine (46) computes a real-time radiation dose delivered to the tissues based on the tissue radiation absorptive properties mapped from the baseline or planning images to the real-time 3D US images (3).

Abstract: A method for mapping coordinates between images and tracking systems includes providing a calibration tool having a fixed geometric shape. The calibration tool includes first sensors associated with an imaging mode and second sensors associated with a tracking mode. The first and second sensors are distributed and mounted at known locations on the fixed geometric shape. The first sensors are located in a field of view of an imaging system to determine a position of the calibration tool in image space. The second sensors are tracked to determine a same position of the calibration tool in tracking space. The image space and the tracking space are mapped in a common coordinate system based on artifacts of the calibration tool.

Abstract: A system for providing navigational guidance to a sonographer acquiring images may provide haptic feedback to the sonographer. The haptic feedback may be provided through an ultrasonic probe or a separate device. Haptic feedback may include vibrations or other sensations provided to the sonographer. The system may analyze acquired images and determine the location of acquisition and compare it to a desired image based, at least in part, on the acquired image. The system may then provide the haptic feedback to guide the sonographer to move the ultrasonic probe to the location to acquire the desired image.

Abstract: A system and method to support exploring the interior of an object. The system 100, 200 includes a graphical user interface generator (GG) to generate a graphical user interface (GUI). The graphical user interface (GUI) includes an indicator (NC) of a current position of an interventional tool (IT) inside an object (OB). There is also an exploratory indictor (PC) to indicate material composition and/or type that surrounds the tool's tip (TP) at a current position in the object (OB). The exploratory indicator (PC) includes a pointer element for a current reading against a dial element for a range of possible values.

Abstract: An ultrasound system includes a 3D imaging probe and a needle guide which attaches to the probe for guidance of needle insertion into a volumetric region which can be scanned by the 3D imaging probe. The needle guide responds to the insertion of a needle through the guide by identifying a plane for scanning by the probe which is the insertion plane through which the needle will pass during insertion. The orientation of the insertion plane is communicated to the probe to cause the probe to scan the identified plane and produce images of the needle as it travels through the insertion plane.
