Abstract: A medical-imaging digital-computing platform serves to access a plurality of data objects and to execute an iterative process with respect to these data objects. The data objects themselves each at least generally pertain to portions of the human anatomy and may comprise, for example, both a source data object and a target data object. The platform executes the iterative process to determine at least one of a labeling of a portion of one of the data objects and a geometric relationship between at least portions of at least two of the data objects. This can be done, for example, by automatically employing both a segmentation module and a registration module as steps within the iterative process. This can also comprise determining when to automatically generate an intermediate data object to provide as input to at least one of these modules.

Abstract: Embodiments of the present invention are directed to techniques for providing an environment for the efficient execution of recognition tasks. A novel environment is provided which automatically and efficiently executes a recognition program on as many computer processors as available. This program, deconstructed into separate tasks, may be executed by constructing a dependency network from known inputs and outputs of the tasks, applying project planning methods for scheduling these tasks into multiple processing threads, and dynamically assigning tasks within these threads to processors. Therefore, an efficient schedule of tasks to complete a recognition program can be created and executed automatically, for any type of recognition problem.

Abstract: A method of constructing a navigation table relating a set of images representative of a region of interest in a subject to a reference system with reference positions indicating known anatomic landmarks of a reference subject comprising providing reference positions for two or more images identified with two or more anatomic landmarks indicative of the region of interest with reference positions of known anatomic landmarks corresponding to the identified anatomic landmarks, and determining reference positions for the remaining images by interpolation.

Abstract: An electronically commutated motor (20) has a rotor (28) and a rotor position sensor (30), which sensor, during operation, furnishes a rotational position signal (34). A stator interacts with the rotor (28). The stator has a stator winding strand (26) in an H bridge (22), and a control apparatus (36) which, during operation, performs the steps of: (A) controlling the H bridge (22) so that current pulses (+i1, ?i1) flow through the stator winding strand (26), in alternate directions, each pulse starting at a first point in time (t1); (B) at the beginning of each commutation, starting from a second point in time (t2), operating in short circuit the winding strand (26), in order to cause a decreasing loop current (I*) through the stator winding strand (26), which loop current (I*) reaches zero at a third point in time (t3); and (C) stepwise modifying, toward a minimum, the time interval (TCC) between the first and third points in time (t1, t3).

Abstract: An electronically commutated motor (ECM 20) has a rotor (28) and a stator, associated with which is a winding arrangement (26) to which electrical current (i1) is applied to drive the motor (20), a computer (36), and a PWM generator (84) associated therewith. The motor (20) is designed for operation in a parameter range that encompasses at least one variable parameter, e.g. operating voltage or ambient temperature, that can have different values. The computer (36) is configured to operate by carrying out these steps: After the motor (20) is switched on and before normal startup begins, during an initial time phase (T1), current (i1) delivered to the stator winding arrangement (26) is switched off and on using a pulse duty factor (pwm) derived from said variable parameter, in order to produce startup of the motor (20); subsequent to phase (T1), when the rotor (28) is rotating, normal startup is performed.
