Problems solved by technology

Unfortunately, TAUS cannot visualize the anatomy of interest, as the rectum, bowel, applicator, and needle may not be visible in the acquired image
Similarly, TRUS may not be able to visualize the bladder, bowel and applicators
Furthermore, the combination of TAUS and TRUS presents alignment and calibration difficulties in addition to introducing undesired workflow complexity in the operating room
In addition, the presence of air in the field of view complicates the use of ultrasound modes

Embodiment Construction

[0020] Provided herein is the integration of an ultrasound (US) element, an array of US elements, or a US probe with a brachytherapy applicator to enable 3D conformal dosing for cervical or other cancer patients at the point of care in the operating room Implementation of planned equipment and systems. The disclosed embodiments may integrate a US element, element array, or probe with a brachytherapy applicator in various ways as described in more detail below. In some embodiments described below, a US element or array of US elements may include one or more crystals or other materials capable of generating and receiving US signals, and a US probe may include a US Equipment moved to another location. Furthermore, it should be noted that the embodiments described below may be implemented separately or in any suitable combination, depending on specific implementation considerations.

[0021] Turning now to the attached drawings, figure 1 A brachytherapy system 10 comprising a g...

Abstract

A brachytherapy system includes a brachytherapy applicator. The brachytherapy applicator includes an applicator tube and a radiation source configured to deliver radiation to a tumor. At least a portion of the applicator tube is configured to conform to at least a portion of a patient's anatomy. At least one ultrasound element or probe is coupled to or embedded with the applicator tube.

Description

technical field [0001] The present disclosure relates generally to applicators (applicators), and more particularly, to brachytherapy applicators that include ultrasonic elements. Background technique [0002] Brachytherapy is a type of radiation therapy that has proven effective in treating various types of cancer, such as cervical cancer. During brachytherapy, radiation is delivered to the cancerous area by positioning the radiation source close to the tumor, usually by using a physical applicator equipped with the radiation source. The brachytherapy procedure may offer advantages over external beam radiation therapy by improving the targeting of cancer cells, thus reducing the likelihood of healthy cells being irradiated during treatment. [0003] The development of a conformal dose plan for cervical cancer patients receiving brachytherapy is generally guided by images obtained via one or more imaging modalities. For example, in some cases two-dimensional (2D) x-ray ima...
