It consists of a system for palpation of the rectal face of the prostate that transforms the information collected into objective, reproducible and useful information. The system makes it possible to identify areas of high rigidity reaching the entire peripheral area, transforming a diagnostic maneuver for prostate cancer into an objective one, which until now has been subjective and unreliable. All this in a short space of time, carried out in a less aggressive and more objective way than rectal examination. The device consists of a manual electronic instrument with a handle (1) and a scanning rod (3), which includes at least two concentric force/pressure sensors of different heights, as well as an ultrasonic imaging system which, through means of connection to external devices for analysis/control, allows the data obtained to be analyzed and the anatomy of the prostate being analyzed to be visualized in real time.

The present invention is directed to a prostate measurement system including an improved medical assembly allowing for the accurate measurement of a patient's prostate to be subsequently used in determining whether the patient is at increased risk of having prostate cancer or other prostate-related issues.

In some examples, a medical system includes a medical device. The medical device may include a housing configured to be implanted in a target site of a patient, a light emitter configured to emit a signal configured to cause a fluorescent marker to emit a fluoresced signal into the target site, and a light detector that may be configured to detect the fluoresced signal. The medical system may include processing circuitry configured to determine a characteristic of the fluorescent marker based on the emitted signal and the fluoresced signal. The characteristic of the fluorescent marker may be indicative of a presence of a compound in the patient, and the processing circuitry may be configured to track the presence of the compound of the patient based on the characteristic of the fluorescent marker.

Methods and systems for diagnosing cancer in the prostate and other organs are disclosed. Exemplary methods comprises extracting texture information from MRI imaging data for a target organ, sometimes using two or more different imaging modalities. Texture features are determined that are indicative of cancer by identifying frequent texture patterns. A classification model is generated based on the determined texture features that are indicative of cancer, and diagnostic cancer prediction information for the target organ is then generated to help diagnose cancer in the organ.

An apparatus for use in a minimally invasive prostate cancer detection system, using a fluorophore peptide dye conjugate compound which has at least one absorption wavelength in a range of 380 to 1400 nm, wherein said compound attaches to a prostate-specific membrane antigen (PSMA) expressed by a prostate cancer cell. A photo-acoustic imaging probe to be inserted in at least one of a rectum, urethra, or placed proximal the prostate. The probe having an emitter to emit a first signal at the prostrate and a prostate cancer, excite the conjugate compound and a receiver to receive a second signal from said conjugate compound, thereby indicating a cancerous region of the prostrate. A processor unit connected to said probe, is configured and operable for receiving and processing said to produce a tomographic representation of the prostrate.

In some aspects, the present disclosure provides gadolinium based sensors which may be used to image zinc ions in vivo. In some embodiments, the compounds show appropriate reactivity with zinc ions while maintaining high relaxivity to achieve improved background relative to other sensors.

A system for detecting tumor margins includes a topical protease-specific, fluorescence imaging probe that is activatable by enzymatic activation to produce a visually differentiated signal upon topical application to a targeted cancer cell that secretes an enzyme that activates the protease-specific, fluorescence imaging probe, an applicator for topically administering the imaging probe to the cancer cell; and an imaging device to detect activation of the imaging probe administered to the cancer cell.

Systems and methods for detection, grading, scoring and tele-screening of cancerous lesions are described. A complete scheme for automated quantitative analysis and assessment of human and animal tissue images of several types of cancers is presented. Various aspects of the invention are directed to the detection, grading, prediction and staging of prostate cancer on serial sections/slides of prostate core images, or biopsy images. Accordingly, the invention includes a variety of sub-systems, which could be used separately or in conjunction to automatically grade cancerous regions. Each system utilizes a different approach with a different feature set. For instance, in the quantitative analysis, textural-based and morphology-based features may be extracted at image- and (or) object-levels from regions of interest.

A dual modality probe is disclosed having both a gamma probe sensor and an ultrasound sensor. A dual imaging system is provided having the probe and at least one external gamma imaging detector and a data acquisition computer system for collecting data simultaneously from the gamma probe sensor, the gamma imaging detector, and the ultrasound sensor of the probe. A method for evaluating a target organ of a patient utilizing the probe and imaging system, and performing a biopsy of the organ is disclosed.

An inductively coupled magnetic resonance local prostate radio frequency coil (10) includes at least two connected electrically conductive loops (50) and an interface device (80). The at least two connected electrically conductive loops (50) are tuned to receive magnetic resonance radio frequency signal components along an axis of a subject disposed in a main magnetic field (B0) orthogonal to the axis of the subject (i.e. an open MRI system having a vertical magnetic field) and generate one or more currents indicative of the received magnetic resonance signal components. The interface device (80) connected to the at least two conductive loops transmits measures of the one or more currents to a signal processing system.
