Problems solved by technology

[0007] The disadvantage of tracking methods is that they require expensive and time-consuming image capture, which (in the case of X-rays) may expose the patient to additional ionizing radiation each time a radiography is performed

Embodiment Construction

[0025] Two general modes of operation are described in the context of the present invention: A) thresholding to determine that motion has occurred, and stopping therapy until position can be reassessed and compensatory movement made in the effector before resuming therapy; The new 6DOF position is inferred and subsequently prompted for compensatory movement in the effector before resuming treatment. It is to be appreciated that various other modes may utilize concepts from either or both of these modes, alone or in combination.

[0026] As will be detailed, in operating mode A, detection of movement can be as simple as detecting a change in force on a single strain gauge, or a change in sensor readings on a force sensing matrix (e.g., using matrix subtraction or cross-correlation) . In thresholding, a simple determination is made that movement has or has not occurred. In this case, there is no specific inference as to what the new position of the head is. In the case of ste...

Abstract

An array of force sensors for determining a position of an object, detecting motion of object, and tracking motion of objects in 3D space are described herein. In particular, an array of force sensors can be used to monitor anatomical motion during medical procedures, such as head motion during cranial radiosurgery, to maintain a desired alignment with the anatomical feature. Alerts can be posted to the medical machine operator and the radiosurgery system or scanner can make compensatory adjustments to maintain the desired alignment either after suspension of treatment or dynamically during treatment. Methods of detecting a position, movement or tracking motion of an anatomical feature are also provided herein.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit under 35 USC §119(e) of US Provisional Application No. 62 / 747,626, filed October 18, 2018, the entire disclosure of which is incorporated herein by reference in its entirety for all purposes. technical field [0003] The present disclosure relates generally to the fields of positioning and motion tracking, and in particular to computerized surgical navigation, robotic medical therapy, and stereotaxic radiation surgery. Background technique [0004] Assignment of a computer model of the location of surgical anatomy in both virtual and real space when performing computerized surgical navigation, or computerized stereotactically or image-guided guided procedures including stereotaxic radiation surgery Location. If the patient moves or is moved, and this change in position of the anatomy is not accounted for, the procedure may be misdirected, thereby potentially producing harmful resul...
