Embodiment Construction

[0044] figure 1 A schematic block diagram of an embodiment of an ultrasound probe positioning system 100 for positioning an ultrasound probe unit 104 onto an external object 110 is shown. The ultrasound probe positioning system 100 comprises a controllable drivable positioning unit 102 for holding the ultrasound probe unit 104 and for moving and positioning it at a target position of an external object 110 . In this specific ultrasonic probe positioning system, the positioning unit is a mechanical arm. In this particular case, the external object 110 is an ultrasound-monitored patient object. The ultrasound probe positioning system 100 includes a positioning control unit 106 configured to: provide target positioning data indicative of a target location for establishing mechanical contact of the ultrasound probe unit 104 with the patient 110, and upon moving and positioning the ultrasound probe at the position Control the mechanical positioning unit 102 when it is at the targ...

Abstract

An ultrasound probe positioning system (100) comprises a positioning unit (102) for holding an ultrasound probe unit (104) and for moving the ultrasound probe unit and positioning it at a target position and a positioning control unit (106) configured to provide target positioning data indicative of a target position that establishes a mechanical contact of the ultrasound probe unit with an external object (110) and to control the mechanical positioning unit in moving and positioning the ultrasound probe at the target position. The positioning unit comprises a force actuation unit (108) configured to adapt a pressing force amount of a mechanical pressing force exerted on the object in response to a variation of a counterforce amount so as to maintain a predetermined net pressing force amount exerted by the mechanical pressing force against the counterforce.

Description

technical field [0001] The present invention relates to an ultrasonic probe positioning system and to a method for controlling the ultrasonic probe positioning system. Background technique [0002] Frequent imaging during the course of radiation treatment (image-guided RT, IGRT) can assist in providing more accurate radiation dose delivery to the target and less toxicity of the delivered radiation to normal tissue. In current clinical practice, such frequent imaging is suitably performed using cone-beam computed tomography (CT) scanners. However, this imaging modality requires invasive implantation of fiducial markers, adds additional radiation dose to the patient, and does not allow for mid-fraction motion monitoring. [0003] An alternative involves the use of ultrasound (US) imaging. US imaging is harmless to the patient, relatively inexpensive, and allows real-time volumetric organ tracking. Ultrasound imaging is used in conjunction with medical treatment techniques s...
