摘要： The invention provides a method and apparatus for monitoring a thermal effect of a conformal thermal treatment to diseased tissue in a target volume. The method includes acquiring a reference image of the volume containing the diseased tissue at a first position of the device, determining a baseline temperature distribution of the reference image, acquiring an image of the volume containing the diseased tissue while delivering a treatment to the volume, performing a phase subtraction between the image and the reference image to determine a change in phase between the image and the reference image and determining a current spatial temperature distribution in the volume containing the diseased tissue.

摘要： A system and method for fluid control in a thermal therapy system is disclosed. A fluid circuit permits passage of a fluid through a fluid circuit, including into and out of a treatment zone so as to cool or heat or maintain a temperature in said treatment zone at or near a desired temperature. The desired temperature may be programmably set to a given value or within a band of values using a processor and a temperature controller. In some aspects, leakage of fluid from a patient or from the fluid control system is captured by a leak-proof member to protect imaging and treatment equipment from damage.

摘要： The present invention provides a method and apparatus for delivering and controlling thermal therapy to a volume of diseased tissue. Specifically, the invention includes using thermal imaging and other inputs to determine an acoustic (ultrasonic) treatment regime employing interstitial ultrasound applicators to deliver a required therapeutic temperature or thermal dose to the affected region in a body or organ. Various aspects of the treatment that can be controlled include individual transducer element operating power and frequency, as well as the rate of cooling and rotation of the entire applicator.

摘要： An apparatus for driving and controlling ultrasonic elements includes a computer-based host unit that determines driving characteristics with which to drive the ultrasonic elements; a microprocessor-based controller that receives an output from the host and provides signals representing a frequency and/or an amplitude characteristic; a frequency control circuit receiving the frequency characteristic signal; an amplitude control circuit receiving the amplitude characteristic signal; an RF amplifier acting on an output from the frequency and/or the amplitude control circuits to provide an amplified output signal corresponding to the frequency and/or amplitude characteristic; a coupling circuit that couples the amplified output signal to the ultrasonic elements and provides a forward output signal to a first RF detector circuit and a reverse output signal to a second RF detector circuit; and an analog-to-digital converter that receives an output of the RF detector circuits and provides a corresponding converted output to the controller.

摘要： An apparatus is disclosed for thermal therapy in a male prostate patient. The apparatus includes, in preferred embodiments, a long tubular element that is to be inserted into a patient's urethra so that a first tip end of it reaches up into the patient's diseased prostate. The elongated portion includes a narrow cylindrical tube within which an ultrasonic array is disposed along the long axis of the cylinder. Fluid is pumped into and out of a treatment zone of said patient as needed to control a temperature of a region in said treatment zone. A motorized driver is used to controllably rotate said elongated portion and the ultrasound array therein about the long axis of the apparatus so as to deliver acoustic energy to said diseased tissue. Various control and monitoring components may be used in conjunction with the present apparatus to design, control, and terminate the therapy.
