Abstract:
Provided are a method and apparatus for monitoring a temperature using an ultrasound wave. The method of monitoring a temperature using an ultrasound wave may include generating ultrasound speed data according to temperature in tissue of a target object, from ultrasound speed data according to temperature in each component forming the tissue, based on volume fraction of each of the components; and estimating a temperature of the tissue based on an ultrasound echo signal reflected by the tissue and the generated ultrasound speed data according to temperature.
Abstract:
A method for controlling a temperature of a tissue and a temperature controlling apparatus using the method. According to the method, a tissue parameter of a target tissue is obtained in advance and used to determine an optimum intensity of ultrasound irradiation in order to maintain the target tissue at a target temperature.
Abstract:
An apparatus and a method are provided to generate an ultrasound to be transmitted from an ultrasound irradiation device. The apparatus and the method include acquiring a medical image including anatomical information about a subject, and calculating characteristics of a tissue in the subject, which may affect propagation of the ultrasound based on the medical image. The apparatus and method also determine a parameter of the ultrasound to create a focal point on the subject using the calculated characteristics, and generate the ultrasound according to the determined parameter.
Abstract:
Provided are photomask and a method of correcting errors thereof. The photomask includes a multilayer reflection film covering one side surface of a substrate and an energy receiving layer covering the other side surface of the substrate. The method includes determining a local correction position on a frontside surface of the photomask according to a detected error of the photomask, and locally applying an energy beam to a backside surface region of the photomask aligned with the local correction position in a thickness direction of the photomask. The invention may be applicable to structures other than photomasks that benefit from modification of surface heights or selectively applied stress.
Abstract:
Provided are medical apparatuses for simultaneously performing radiotherapy and hyperthermia therapy and methods of treating an affected area. The medical apparatus includes a table where a subject is placed; a driving unit configured to move the table; a treatment device configured to treat an affected area of the subject; and an ultrasonic transducer configured to increase treatment efficiency of the affected area.
Abstract:
Provided are methods and apparatuses of transmitting ultrasound by adjusting positions of a plurality of ultrasound generating elements within an applicator to direct the ultrasound waves at a position desired by a user.
Abstract:
An ultrasound treatment apparatus includes a transducer configured to irradiate ultrasound waves onto an object, and a membrane disposed in an irradiation direction of the ultrasound waves and to form, with the transducer, a space in which a cooling fluid circulates. The apparatus further includes a first temperature sensor configured to measure a temperature of a skin of a patient contacting the membrane, and a second temperature sensor configured to measure a temperature of the transducer. The apparatus further includes a cooling unit configured to circulate the cooling fluid based on the measured temperatures.
Abstract:
